What I'd like to see is a pocket design lesson. Emphasis on placing entities in the exact postion on the screen, trimmed etc. Here's what I suggest for a real world design:

A part that is 4 inches by 3 inches by .75 inches thick. It has four 0.5 inch holes placed in each corner with the centers .75 inches from each edge. In the center of the part is a pocket machined .250 inches deep, the pocket has an approximate shape of a keyhole; an arc with a radius of .490 inches joined with a rectangle of .45" wide and 1" long.

Once drawn, I'd like to see the steps for generating the tool path that only cuts the pocket, not the entire surface & not the holes which must be drilled.

This can & should span several tutorial threads for each step.

Perhaps an inverse of the design where the keyhole is an island instead of a pocket. I know there is more than one way of doing it, using primatives & boolean functions is quick, but I'd like to see it done using the conventional drawing tools. I'll even do homework & practice! Thanks!

Well, I have figured out how to spell CAD. I am working on the other one "CAMM" or something like that. I installed the v20 demo of BobCAD and was thrilled that I could open an example file of a bottle. Big question is, "howcome it's only half a bottle?".

What I'd like to see is a pocket design lesson. Emphasis on placing entities in the exact postion on the screen, trimmed etc.

Sorin has this tutorial. You may wish to contact him or Bobcad about a training course. They are pretty cheap and Sorin gives you several tutorials in a computer video format.

Have you looked at Bobcad's web sight.

www.bobcad.com then click the downloads tab....a few tutorials there.

The reason that there is only one half of the bottle is because you can't machine a full diameter bottle on a mill. It must be a core (upper half ) or a cavity (bottom half. Just itry to imagine ast the tool goes abover top of the bottle and mills it , now it has to go down below and cut the bottom....alt the top will cut off. If you want to see the whole bottle, rotate the bottom (or upper half that you have and choose "make copy). There you have it...Cheers, a adult beverage of your choice...LOL
Hope this helps. I want to take you guys one the lesson program and actually do video on how to do the key hole example. The problem is that the video file size can be a bit large for an email. Any suggestions???? I can burn it on a CD but now we are talking mailing expenses. I have some clips that will take you from creating the drawing to getting the G code done. Plese let me know of you have any suggestions on how to post them here for you.
Happy New Year to you all!
Sorin
PS: Make sure you wear some type of wrist brace while using your PC... Just got a Carpall Tunel surgery last week on my right hand..Not a fun thing trying to be a lefty for a while.

you can upload them to a site I read about and then everyone can go to that site and download them . I wil look and find the site for you and post it . It is a free site also.

www. yousendit.com

you can upload and send emails to those who want it. Then they go to the site and download simple.

www. dropload.com

Thanks Ken,
I will check it out and then gladly have there for you guys. I will need a couple days for my hand to get better. I just had a carpall tunel surgery and will like to saty of the PC for a couple days....that if I can resist. LOL
Best wishes to you all,
Sorin

sounds good . you should let everything heal first

here is my email whenever you feel like doing it let me know and I will defanatly download them thanks

Hand is starting to feel better......I will start with first tuturial tomorrow evening. That will be on how to draw the part using Bobcad (i will be using V20.5 but V18 or 19 will work the same). The second tutorial will be creating the pocket for the key hole and next how to generate a G code from it. The last one will be for creating tool path and leave the key hole as a island. A fair warning to you all....I was born in Romania and live in the US for over 30 years now but still have an accent. You former students know what I mean....LOL
Best regards to you all and I hope that you will enjoy the class.
Sorin
PS: The files will be posted at www.savefile.com

Attached is the finish drawing of the part that we are going to work with. It is drawn in 2 D since that is all that we need for this particular part. I have changed from just a plain square for the key hole to 2 lines at 240 and 300 degrees so the part looks more like a "Key Hole" as per your request. I also added some filets to the sharp corners of the inside of the "key hole". The video on how to do this will be uploaded sometimes tonight. Hope you all enjoy it.
Best regards,
Sorin

Hi Guys,
Sorry it so long to get this done. I kinda pushed my lock with my surgery on my arm and and I was in lots of pain...However, I got the first video done. It shows how to draw the part that you were asking for and I have psted as a DXF in my previous post. So here it is, I hope to have the rest done tonight (it wil be another one that is going to rough the inside of the key hole, one that is going to rough the part and leave the key hole as a island and another that is going to cut one of the tool paths.
Best regards,
Sorin

Let me try attaching the file again...
Sorin

Hello again,
I guess the file is too big to uploaded on the forum. It can be downloaded from the following link: http://savefile.com/projects/561668
I apologize for the inconvenience.

I get voice but no vidio am I doing something wrong?

Ken,
I have played them on my PC and they work fine. They are AVI files that are played with windows media player. I have created a DVD file with all 3 of them plus a menu but I need to find a way to zip the whole folder so I can upload it to www.savefile.com. I will let you know if I find anything else.
Best regards,
Sorin

Ok thanks

They work just fine on my desktop so I must have the wrong settings on my laptop thanks for takeing the time to do this for us.

I don't know why but neither my real player or my windows media player works with this video.

However the player from the software company Sorin records this with will work. It can be downloaded for free at this sight.
http://www.techsmith.com/products/studio/player.asp

I will check more into why this will not play AVI with windows media.

Tim

I found the problem which is detailed here.

http://techsmith.custhelp.com/cgi-bin/techsmith.cfg/php/enduser/std_adp.php?p_faqid=154&p_created=1104264463&p_sid=6aOWtWYh&p_lva=&p_sp=cF9zcmNoPSZwX3NvcnRfYnk9JnBfZ3JpZHNvcnQ9JnBfcm93X2NudD0zMjEmcF9wcm9kcz0mcF9jYXRzPSZwX3B2PSZwX2N2PSZwX3BhZ2U9MQ**&p_li=&p_topview=1

It boils down to the codec is not installed on the system used by Camtasia to record the file. This needs to be installed on the system before windows media will play the file.

To download a codec for this AVI format you can go to this sight. Run the codec install and real media or windows media players will play the file.

http://www.techsmith.com/download/codecsdefault.asp?lid=CodecsHome

Someone else said the above link no longer works so here is the new link

http://www.techsmith.com/download/codecs.asp

that fixed it thanks
I wish I was that smart

I was in one of Sorin's classes and he gave us tutorials aready made with the software. That is how I knew what he used. I just went to the web sight for that company and went through the support page. Nice little recording program. Anyhow it wasn't smarts it was just snoops.

he sure makes it look simple. One of these days I would like to go to one of the seminars .

"t",

I would like to see a tutorial done with tips on how to make pocketing in BobCADCAM much quicker.... clever scripts, strategies, etc.

In the tutorial, I'd like to see pockets machined using cutter comp where you enter a positive or negative cutter comp (negative cuts into the stock, positive stays away) in the machine control. I would also like to see how to make BobCADCAM start pocketing where I choose not where it chooses... without jumping thru a ton of hoops or manually editing the G code.

For those who can't make it to a training class why not sell video's etc. ? I see a market for this based on my viewing of the BobCADCAM V18 videos. The BobCADCAM V18 videos basically follow the manual and go thru the menu choices. In my opinion this is not a particularly effective strategy and it's boring as well.

Perhaps something like a BobCADCAM V20 Power Tips To Save You Time and Money video or whatever.

The BobCADCAM V18 videos are very basic and don't deal with scripts, tips to save you time, etc.

For what it's worth I found the videos presented in this thread to be interesting and well done. The author of the videos expresses concern about his accent in these videos... I see this as a benefit as the voice on the BobCAD V18 official videos puts me to sleep as it's basically a flat monotone. To be honest I got nothing out of the official BobCADCAM V18 videos and it was all I could do to get through them because I was bored to death. I was never bored in the videos presented in this thread. Further the video in this thread moves along at the rate I'm use to at a machining job shop.

"I may have many faults, but being wrong ain't one of them." ... Jimmy Hoffa

the v20 training cd's are better than v18 but not near as good as these here. I would be willing to veiw any of his tutorials he would post. I am not phisicaly able nor wealthy enough to attend his seminars at this time , but if I were I would be there.
Very good lesson Mr Sorin.

Thats because Sorin is a machinist. He actually has used the software in real life not just for teaching. No better teacher than someone who has to actually make it work.

BTW, Sorin may be one of ,if not the, first Bobcad users in a machine shop.

Here is a simple script I did while in Sorin's class. It is a functional script for placing bolt hole circle points. I did not have it actually put circles because you don't need them.

The script allows entry of center position, start angle, arc, and number of points.

the v20 training cd's are better than v18 but not near as good as these here. I would be willing to veiw any of his tutorials he would post. I am not phisicaly able nor wealthy enough to attend his seminars at this time , but if I were I would be there.
Very good lesson Mr Sorin.

Thanks for the heads up on the V20 CD's, Ken. Sadly that's what I figured. I agree with you that the tutorials posted are very well done. What I would like to see is advanced tutorials made available for a reasonable fee covering the subjects I mentioned. It's very clear that the author of the video's has a natural talent for doing CADCAM video instruction.

In my opinion the presentation in the video is excellent and I feel his style of tutorial is the only way to go. I also like that the videos posted use no fancy video effect nonsense and cover machining in almost (I like using cutter comp at the machine :>) ) a real world scenario.

Bottom Line: The quality of the videos posted speaks for itself and stands on it's own. I think we all can agree on that.

As Ken stated all of us can't attend a seminar. Even if someone I know attended a seminar he might get tossed out ... hence a great reason for the author to sell BobCADCAM videos at a reasonable price. Sometimes seminars give rise to arguments over things like the best way to apply cutter comp. :eek:

Can you imagine some of the authors of posts you read on the other web forum attending a seminar for BobCADCAM ? Might be the start of W.W.III.

Lets give peace a chance. (group)

"I may have many faults, but being wrong ain't one of them." ... Jimmy Hoffa

Guys,
Thank you for the kind words and glad to hear that you have found the videos helpfull. Regarding new ones, what else can I do for you? I was going to have a collection of 3 CD's that will include environment settings, post processors tweaking, some scripting modifications and editing and so on. Any other suggestions? Once again, thank you for your kind words.
Best regards,
Sorin

HEY SORIN

We have bobcad v20 and we need some help. Would you or do you know of someone who would spend a day or so with us. Mainly 3d questions. We are located in northern Indiana. The bobcad 3 day training is pretty salty

Thank you, ynkey

what do you mean by salty?
expensive or something like that?

Ynkey,
I don't think that $650 for 3 day is "too salty" based on what every one else (if they even have a training program...LOL)is charging. Let me explain something to you and everyione else here about my self. I have known Bob and been using Bobcad for over 20 years now. Bob and I have become friends and we are trusting each other. As right now Bobcad uses me as the only person to do the trainig and I woul only do trainig for them. It will be wrong for me to go and undercut their prices and do training "on the side". That will break our trust and probably riun our relationship. I wouldn't want to be the one doing that. I hope that you understand my situation. I am helping here because I like helping others and it is free of charge. Hope this doesn't ofends anyone but once again, I can't do that to a friend or the Bobcad organization.
Best regards,
Sorin

Sorin

I appreciate your reply and your position with bobcad. This is the first time I have looked at this site and I did not know. We were quoted a price of 5000.00 dollars ( Ken for us this is salty) for 3 days in house. We probably dont need three days. Just looking for a expert in our area who could help us obviously I am on the wrong site. Again Sorin I am sure you are worth the money, did not mean to cause problems.

Take care , Paul

I just wonderd what salty ment I had never herd that term used. I woild pay the 695 if and go if I could aford it , with just starting to take some courses in cam my funds a depleated. 5000 would realy hurt, maybe Bobcad would work you a deal if you got intouch with the right person, worth a try.

Paul and Ken,
Bobcad sells seminars for $650 if you are willing to attend a class. The seminar lasts 3 days. That is an average of about $230/day for training. The $5,000 is for a "on site" seminar. That means, I have to get a plane ticket, rent a car, hotel and be at your place for 3 days training up to 6 of your emplyees (if you had that many). This is not for everybody but if you had a shop that big with that many employees, then will be worth it (remember, the norm fee is $650/person times 6..) Some of the bigger shops and companies did this. Actually, my wife come up with the plan of doing the seminars at a hotel and have everyone shar in the expanses. That makes it more affordable. Anyway, this is NOT why I got involved with this thread. Not to get you to come to a seminar, just to be able to help you guys that can't afford it to be able to use Bobcad and make some chips. I hope that I didn't offend anyone. If so, then I apologize.
If you guys need any more help or any videos, please let me know what I can do to help.
Best regards,
Sorin

"Bob and I have become friends and we are trusting each other."

It would be nice if Bob*finally*recognized that the "official" BobCADCAM manual and the "official video" are not adequate in any way, shape or form and hired you to redo them as no progress in presentation format appears to have been made in this area since V18. The current Video / Manual support system that is now in place is broken beyond repair and it will not be fixed without making a change in personnel. Not trying to be a jerk but FACTS are FACTS. Perhaps a reassignment of tasks is in order instead of a parting of the ways ? Don't know. Not my business. What I do know for SURE is that something needs to change and should have been changed by now. The posting of your videos was like a breath of fresh air.

IMO, $650 for a three day seminar is very inexpensive. As has been previously covered, for various reasons, some people can't attend a seminar. This is why I proposed selling the videos / etc. as well. Perhaps the problem is that doing so would compete with the "official" BobCADCAM video's ? If this is the case please see my first paragraph of this post.

I am working on a list of issues that you asked for input on and that I think should be covered and will post it shortly.

Finally I would appreciate you forwarding my post to Bob. You can even tell Bob you and I don't always / ever (your choice) get along and that my opinion is based solely on *how content is presented* and on *nothing* else... no matter what someone else might care to argue.

"I may have many faults, but being wrong ain't one of them." ... Jimmy Hoffa

Jon,
I don't work directely for Bobcad and I really don't want to get here into Bobcad bashing. This started as me ofering to take someone up to their question on how to do a sample part. That was it.... I have never seen the videos or read Bobcad's manuas. Don't have time for that. I have spoken to hundreds of people at my seminars and I get mixed responses regarding the videos...I don't have any interest in becoming a critic nor a editor for the videos. What I did for you guys is what I do at all my seminars every week. You and I have spoken long time ago and you know that I am a machinist by trade not a computer geek. Maybe that is the reason that I might come across to you better....I don't know. Anyway, this is the last post that I will respond to in regards with Bobcad's videos, manuals etc. I will only respond to questions regarding help. This is really making me feel unconfortable and that is not what I am looking for or what I had in mind when I offered to help. I hope that you can respect the way I feel. Once again, I am not interested on bashing or promoting and CAD-CAM software, I just want to share what ever I know with everyone else.
Best regards,
Sorin

Sorin
I understand the charges and will do a seminar when the time is right and realy do apreciate the help and all on the site , I may have been misunderstood about my question because I didn't understand what salty ment and I understand that everyone must make a profit. I had my own shop for years till my illness took afect and am now trying to learn a new trade so I can get back to work, I think this is the trade I want to do,and should be able to do it. I am just trying to learn all I can .thanks for all the help.

I followed the links to the download site. Today is 01/14/2006 and it claims the project ID is invalid. Out of date and deleted? Would love to look at them.

Wes

Ken,
Ididn't mean anything about what you have said. I was answering to Jon and his remarks about Bobcad and Bob personally. I didn't think that this thread was about what is wrong or right with Bobcad. This started as a simple thread on how to do a simple part. I still don't know how we got to all the flaming about Bobcad....perhaps that needs to be taken to other threads not in this one. Regardding the message that wtbaker69 that the files were deleted. They were removed after 1 week from the server. These are the rules on that site. I am in Chicago right now and will be flying back home tomorrow afternoon. I will try to post them back again tomorrow evening. My wife has a surgery Monday and I will like to get all this done before that. I will be in Atlanta next Tue. so it needs to be done as soon as I get home so you guys can have the files.
Best regards to you all,
Sorin

thanks and hope all goes well with the wife.

OUT OF DATE AND DELETED!!!!!

It was a free sight and I guess they dont keep them there for long. Took me almost a week to get one of them posted due to failures. I am not sure I will keep posting them there if they only last for a month or less.

If I had the money for the extra cost to have a fixed IP I would do them at my home. The transfer rate is not a problem and I have a Mac that loves web sharing. The only problem is with no fixed IP I would have to update a link every few days.

As asked for and as I promissed... BobCADCAM areas that I feel need to be covered:

How to created tapered walls on a pocket and on an island.

How to make Boolean solid construction faster / easier.

Surfacing toolpath tips.

Toolpath verification is badly lacking in BobCADCAM... what can be done to deal with this ? What do you do ? External verification program suggestions ? Sometimes cutting a solid is very helpful to conceptualizing what is going on in a non-trivial part. Verification/Visualization is so important that one CADCAM program use to be called Virtual "G" and another one is called Visual "M".

Scripting:

While I don't think it's appropriate to try and teach programming / scripting from the ground up I do think it's appropriate to show what kind of scripts you are using / can be used and to take as complete as possible approach to showing the power of BobCADCAM scripts.

Specifically: Showing how scripts you are using help make program construction easier. Examples of easier would be a slots script, G12, G13 scripts, Custom machine canned cycle scripts.... not full detail of the exact code in the script but more like attempting a comprehensive approach to what can be done with scripting. Note: It seems to me that what you did in the Approach / Depart Video with trimming back to cut possible wasted material should most definitely be done in a script as this is something many BobCADCAM users would use all the time. Why do it manually if it can be scripted ?

Programming for Horizontal mills with rotating tombstones with say different parts or different sides of the part being machined or just one part but 3 sides being worked on... does it make sense to start working in 3D for this ?

Lathe programming: Needs to be covered.

see if you can get this video for those that didn't get it the first time It is from sorin on 2d to solid to 2d

a guestion for jon if everything isn't working right in bobcad why stay with it? this is a lagit guestion because I don't know much about cadcam software ,but it seems you do have a lot of issuse with bobcad, and this is in no way ment to critisize anyonr just would like to know .

a guestion for jon if everything isn't working right in bobcad why stay with it? this is a lagit guestion because I don't know much about cadcam software ,but it seems you do have a lot of issuse with bobcad, and this is in no way ment to critisize anyonr just would like to know .

Part of what I do for a living entails supporting multiple CADCAM systems. Many machining job shops use multiple CADCAM systems.

BobCADCAM is not the only system I have issues with.

Here is a question for you... are you getting anything out of what I post both here and on the official BobCADCAM Tech Support Forum ? Has what I have posted made you think about stuff you might not have otherwise ?

jon

"I may have many faults, but being wrong ain't one of them." ... Jimmy Hoffa

well to be honest I have not , but then I am just starting to learn this stuff and what I do use of the program ( very limited ) has worked and when I had a problem with certain options I call and it takes about 2 minutes and all works but this is just the simple stuff at this time. I draw a few parts and convert to g code and send it to my machine and it seems to cut the parts, I have not made any mager long machining jobs yet , I think one did take 1.5 hrs . I am working on some 3d stuff to cut but haven't gotten anywhere nere the extensive items that you are discusing that may be why I don't understand most of your post, but hopefully in the nere future I will know exactly what you are talking about . thanks for replying to my question. I am desperatly trying to learn all of this type stuff.

John,
Bobcad 20.5 has already a tapered walls feature. It will allow you to have different tapers for the wals, each island and further more the depth of each taper can be controlled individually. Really cool stuf since it gets done from a simple 2D drawing. I will make a video of it tomorrow (my wife's surgery got switched to a earlier time so I hope to be home in the evenin g). Anyway, regarding scripts, they are a hybrid between Visual basic and Bobcad's internal commands. If you are a user of Bobcad and have a legal copy of it, Bobcad will let you have a PDF file regarding scripting and their scrips manual. All my students get that from me at the seminars. The support team at Bobcad and my self have a comprehensive colection of scrips (some of them we have written, some we gout from customers willing to share). Al that info is there, all that you or anyone else needs to do is to contact Bobcad's tech support or my self and we will provide you with evrithing that we have. It will be kinda impossible to write scripts with out having any knowledge of VB or fully un derstanding Bobcad and it's internal commands. Glen and Chris Wren at Bobcad are very helpfull and know that stuff better than anyone else. Did you ever contact them and asked them about this??? I am sure they are going to help if you or anyone else asks. Rgarding Boolean functions, they are only 3 options and they are very symple to use, have you tried it ?. They have some pretty self explanatory images with each one of the functions, to make that very symple. Regarding approach depart. I like the way it works and it easy to use. I believe that my video shows how to save some small amounts of material if you need to. I don't think you will need to re write the function since V20.5 has a new feature called "Profile" That can be selected from the "Machine" mode in NC Cam side of the software. By the way, what version of Bobcad do you curentely use????.
I will try to cover the above in few lessons that I am going to start tomorrow evening. Anyway, this is a good start, it gives me an idea of what you guys need . By the way, I am forever gratefull to www.savefile.com for giving me a chance to post these files for you even if it is for a week at the time.
Best regards,
Sorin

Sorin
I would just like to say thank you for your time and effort, being new to all this I have tried various programmes but could not really get to grips with them including Madcam, but I have managed to get a few of your tutorials which have been great and I am now starting to get to grips with things.
Again many thanks.
Keith

Sorin,

Please contact the Bird (Chris) at Bobcad and discuss adding the video files. I have been emailing him and he needs to talk directly to you. They may need toreview the videos before placing them on their sight. Anyhow My bet is they will give you a place to upload.

Dear Sorin,

I would also like to thank you for taking your time, and sharing your experience with us. I'm new to CNC and trying to learn all I can. Your willingness to help is very much appreciated. Hope the wrist is feeling better.

I read through many posts regarding BobCam before I decided to purchase, and in the end figured there simply was no product that came close to the value. I'm going through the training videos that came with my 20.5 and, as mentioned in an earlier post, they so far (I'm only through half) seem to be only going through the menu items. Nonetheless, I'm glad I have them as they are helping me get more comfortable with the software. If BobCad produced a video that starts with the initial design of a complex part, through to the final machining, it would be a terrific aid for me. I presume most of the people on this forum are already proficient in this, but I'm a guy who saw an ad for a second hand CNC mill, got excited, came up with a plan to justify it to my wife, and am now committed to try and figure out how to use it.

In any case, thanks to everyone on the forum. I've learned a lot already.

Randy

Randy and all,
LOL couldn't help laughing about what Rany said.....Justify to the wife for the machine ...Sounds like the story of my lifeLOL. That was a good one, remin ded me many times and situations in my life. Anyway, thank you all for all the kind words. I will continue to contribute to this thread. I just want to let you all know that this morning my wife had a surgery to remove some pre canceros toumors. It all went well and I am back at home. After I feed the kids, I will get on with some lessons, and I will try to post them tonight.
Thanks for all your prayers and for the kind words,
Best regards,
Sorin

Good to hear all went well with the surgery.
Regards

We will continue to pray for her as she recovers. Glad to hear all went well.

"I will make a video of it tomorrow (my wife's surgery got switched to a earlier time so I hope to be home in the evenin g)."

Look forward to seeing it.

"If you are a user of Bobcad and have a legal copy of it, Bobcad will let you have a PDF file regarding scripting and their scrips manual."

The shop I work for owns it. I took Chris's advise and told my boss to upgrade our V19 to V20. First day using V20 I found out that moving the UCS broke the lead-in, lead-out in the new Profiling. I guess this got fixed in 20.5... my boss got sick of what he calls spam from BobCAD and removed himself from the BobCAD mailing list. Most of our users are still using V17. Isn't the only scripting manual that is available what is in the V20.5 manual that Chris wrote and that anyone can download ? I've read it... it's rather incomplete. See the BobCAD forum for others who have said the same thing I'm saying here... for years. I will contact BobCAD tech support and ask about the collection of scripts you are referring to. I would think that BobCAD would put them on their download page. Can't figure out why they wouldn't... everything else is there.... all the manuals, the post processors.

"V20.5 has a new feature called "Profile""

See above. Profile was in V20... just broke when you moved the UCS.

BTW, pocketing should also have the same kind of comprehensive dialog box that Profile does.

"If BobCad produced a video that starts with the initial design of a complex part, through to the final machining, it would be a terrific aid for me."

I believe this is what should have been done a long time ago. I have suggested this be done for V20. It feel on deaf ears and I don't see it happening. Perhaps someone will decide to sell a video like your requesting. In my opinion your on the right track to what is really needed and what has unfortunately not been done.

Going through the menu and covering every command is a very, very poor choice for a video presentation.

John,
I hate to do this but I am kind of running out of patience here. Do you ever have anything good to say about any software??? Using V 17.........Gee, that is about 12 years old technology man...It came around durring Windows 3.1 (remember Windows3.1????!!!!). Anyway, if you or your boss expects everything to be top notch and up to par, then you need to stay up with all the upgrades, updates and fixes. That is why that Bobcad has auto updates. Updates are free and simple to do, just click on "Auto Updates". Don't know of any software whatsoever that doesent have glitches, bugs or short comings. Maybe you do, if so please post it here so we can all find it or learn about it. Anyway, I will like to chalange you to bring something positive or creative to this post. If not let everyone else enjoy what they have and learn how to use it and make money with it please.
Best regards,
Sorin
BTW: In your expert opinion (I know you have used/tryied all of them) , what is the best Cad-Cam package, how much does it cost, do you own a license for it and what are the features that makes that package so great for the money you spend, also what are the bad points, short comings and bugs for that package. Remember, not everyone can spend 17-20 K to buy software.
Sorry but I had to ask.
Sorin

To all,
Some new videos done. It is about 12:30 AM. I need to catch some ZZZZZZZZZZZZZs. I will upload them tomorrow when I get to Atlanta. Lots of time to kill in a hotel room...LOL. Anyway, I talked to someone at savefile.com and I will be able to upload the old videos as well as the new ones and leave them longer.
Good night my friends,
Sorin

"If BobCad produced a video that starts with the initial design of a complex part, through to the final machining, it would be a terrific aid for me."



What features, since there are so many available, should the video cover. In version 20 there are 5 types of pockets, spiral thread milling, profiling with aproach and depart, splines, facing, nesting, 12 types of surface creation, 5 types of solids, 3 types of booleans, 8 types of lines sketching, 3 types of fillet, skins, converting between 2d and 3d, 5 types of surface, text to vector, dimensioning, fitting text to path, driling,tapping,etc.. And who knows how many ways to change things like attributes, trimming, extending, break, divide, etc.

Thats not even all to cover in milling. Then there is lathe and wire. Now there are all the other stuff in the NC window and scripting to do. I am sure most of these would not be covered in one example unless it was driven towards that goal.

Could you post an example of what you feel the part should be or what it should cover. I personally use Bobcad for 95% solid work and haven't come close to using all of the options in solids. The other 5% has been in pocketing that might be too time consuming to program on a Mazatrol. So my ideal of the perfect video would most likely fall very short of what you need.

Sorin,

I have started posting the downloads into individual threads to help everyone find the files and what they do. There are several from the Bobcad forum now checking through here to find them.

It seems if we post in one thread the download message gets lost somewhere in the middle of 10-30 meassages. This way at least they will be the first message and if the link changes we can edit the first post as well.

Your last video I posted got 20 downloads in the first 4 hrs.

I was curious if there was a video done covering rough-out cutting. Is there one up there or someplace? If not, it sure would be nice to see one of those videos!

John(bloy)

p.s. Sorin... I really want to thank you for whipping out those tutorials and helping us smooth out our control of BobCad !

I will have to check but there is one that covers pocketing and I am sure it covers the roughing of pockets as well.

Could you be more specific on what operation you would like.

I'm about out of patience myself, Soren. Like you don't own BobCAD I don't own the company I work for. If my boss prefers to use V17 that's his choice, not mine and not yours. He took your training by the way and he did very little with it. Again, his choice not yours or mine. Also, any chance you can spell my name right... it's jon not john. I would appreciate the courtesy.

As far as staying up to date, my boss purchased V20 like I asked him to after I talked to Chris about V20... not sure why your still confused about this.

I do have a favorite CADCAM software. Our company doesn't use it. It's a very capable package and I fail to see why mentioning the name of this CADCAM package in the BobCAD Forum is appropriate. Why do you think it's appropriate to do here ? Even if I mention it how in the world is it relevant to BobCADCAM and what BobCADCAM needs ? We use multiple CADCAM systems... a point I have also made clear in *this* thread. Many machining job shops today have /use mulitple CADCAM systems not just one.

In any case, in my post where I stated the need for showing tapered walls for pockets and islands I forget to state that I wish to *easily* create a chamfer on the islands as well. Sorry I left this off as I was focused on trying to make my points clear on how I think BobCADCAM needs to be improved in the official BobCAD Tech Support Forum and I apologize for my mistake in leaving this out. This picture should make it very clear the kind of thing I wish to be able to do in BobCADCAM quickly and easily.

Maybe you could make us a video and let us beginers learn some of what you know. If I ever get any of this down I will be more than happy to share what I have learned from all this. Please don't make Sorin and the others upset to the point they wil no longer participate, I am learning quit a bit from them. Thanks

I suggest anyone who thinks I don't support improving BobCAD check out the official BobCAD Tech Support Forum and take a look at the effort I have put in to making positive suggestions. I also suggest that others take a very close look at the www.practicalmachinist.com (CNC Forum) and read how BobCAD is viewed by the majority of posters there. There is a reason BobCAD is perceived like this and by reading these threads it should be clear to anyone that's even remotely objective that I'm all for improving this product and it's image problem. I would appreciate anyone replying to this post *FIRST READ* what's on www.practicalmachinist.com (CNC Forum) as well as what I have posted on BobCAD's official tech support web board.

The FACTS speak for themselves.

Ken,

I suggest you get a better understanding of the problems BobCAD has and must deal with to understand where my experience is coming from. You can do that by reading the CNC Forum at www.practicalmachinist.com and seeing how much effort I have put into trying to straighten out the problems. I understand the video is very helpful to you... in someways they are to me as well but this does not excuse you from understanding what the situation really is with BobCADCAM and how it's perceived by many machinists. Put the effort into this and you will have a much better understanding of where I and many others are coming from.

One of the big problems for machining job shops using BobCADCAM is that so many are attracted by BobCADCAM's low price and many who are attracted have very little / no job shop machining experience. They also have *no idea* what is expected and how strict the time requirement to produce quality programs that don't need to be dry run at the CNC machine are.

If you expect me to understand your problems then I expect you to understand how BobCADCAM is often perceived in the market place as well as the type of pressure many machining job shops are under. Do some reading on www.practicalmachinist.com and see if you can understand why what has been posted has been posted.

Trent,
I have spoken with Chris (bird) today and he sent me a link to the ftp site. I am gettin my onw site so I can have full control over what is going on. I will also like to thank you all for the patience with this issue. I will continue to help as long as Paul is OK with it.
The old files are posted back on savefile.com (see link in one of my previous posts) I will have to delete that project in 48 hrs because I have other files to post (setting environment, tweak your post and ooopy tapered pocket with tapered islands and to make the trolls happy, I will add a chanfer to the top....LOL).
Regards to all,
Sorin

Sorin,

I promise I am not angry about it but my name is Tim....lol Really it is!

I am glad to hear Bobcad is setting you up. Also there was a question on the Bobcad sight that wished to buy these videos on CDs. He doesn't wish to spend the time downloading but wants to play them from the CD. He is willling to pay but wants to know how to go about getting them.

Anyhow I hope Trent was a nice guy!

Tim

Got to admit one thing...it's the most exciting forum I've been on.
:cheers:

LOL.

Just remember there is a difference in exciting and trying to do the right thing to really make the needed changes in BobCADCAM. I do believe that you are trying very hard to make the needed changes. I have no doubt that "newbies" have no idea how BobCADCAM is perceived. Changing the perception can only be done with teamwork because the problems go a lot deeper then documentation... although documentation is certainly a big problem.

Night "Trent",

jon

For the second time in this thread, I've edited and deleted posts. This might be the only thread here I've ever had to do that. Continue on topic, or else!!

(chair)

Looks like the cleanup crew has been here. Removing posts. But why did they remove one of mine? I did not post anything against the rules.

Anyhow, Glad to see they were paying attention.

Edit: Guess I do understand. My post is meaningless without the other posts that prompted it.
Good Job!

For the second time in this thread, I've edited and deleted posts. This might be the only thread here I've ever had to do that. Continue on topic, or else!!

Thanks Gerry,
I hope this "help" thread can continue with the idea of learning to use BobCadCam in a proficient manner. I think every forum needs to be edited to keep distress to a minimum while emphasizing a spirit of focused amicable exchange.

John (bloy)

Tim and all,
When I first got involved with this, it was because someone was asking for help. I figgured that why not help someone. I have greated the videos and everyione was happy. On my way with new ones and hopefully you guys can all benefit from it. Along comes one individual that has been kicked around in every news group and started to do what he does best. Complain about everything and contribute at all. Same stuff that he is well known all over the internet for the past 10 years or so. Now I get my messages deleted and get a private message\notice. I really don't need this and have no time fro playing games. It was done with good intentions and it turned up sour.....I guess the famous JB started to cry and now everyone is paying the price. Oh well, I will bid goodbye to you all and it was nice talking to you all. I will no longer participate in this group and perhaps JB can take over from here on and delight everyone with his vast experience.... Tim (tjones) has my private email address ad you can ask him for it through a private message. I will continue helping you if need it but NOT here. It is sad that it had to end this way. Good luck to you all.

I am sorry to see Sorin go. He will be working a little more with Bobcad on the videos and hopefully I will be able to continue posting video links for you here. You may also be able to have discussions with him on Bobcad's web sight forum. However the other individual is there as well and may still be a problem with battles towards Sorin. (and others)

Ain't that something I sure hope Jon can produce some EASY to use videos to make up the difference ! I sure was looking forward to the next videos, I will met Sorin one of these days and thank him in person, I got a notice there is a seminar in Dallas first week of FEB but I will not be able to make that one sense I go to school on Tuesday and Thursday.
Thanks for the help Sorin.

I'm with you Kenneth. With everything Sorin's got going on right now, he goes out of his way to help us out. I think I'm safe in saying almost everyone will miss him. Thanks to Tim for his help as well. I watched the videos last night, and got a lot out of them, especially the 2d to 3d.

This happens way TOO often... Someone has to "get in someone's face" and ruin it for everyone. JB just has to push it and push it(right or wrong) until something gives... and it's never good.
Sorin, if you still read here, Thanks for all your efforts! ....wish you'd give it another chance!

Now I get my messages deleted and get a private message\notice. I really don't need this and have no time fro playing games..

For the record, several people's posts were edited/deleted, to remove personal attacks, and inappropriate comments, in order to keep the thread on topic. No pertinent information was deleted, just cleaned up a few things. Sorry Sorin feels this way.

I posted this request in the offical BobCAD Tech Support Forum:

Request For Training Enhancement

I think it's time that BobCADCAM had an official training video that covers creating and machining a complex part start to finish.

I have done a good deal of thinking about this today and have come to the conclusion that this video could be done by someone who did not have an extensive machinist background if they were to work with a machinist who did have an extensive background and who provided assistance on how the part would be fixtured and the best way to machine the part. The current video offering, from what I'm told, (I only have the V18 BobCADCAM video's) is much like V20 only better video production. The real problem with these videos is that going through every command is a very poor way to learn how to properly use a CADCAM system. When you model and machine a complex part in video the user can follow along doing the same thing in BobCADCAM.

Without a doubt, modeling and machining a complex real world part is the best method of teaching someone how to use a CADCAM system that I know of. This is an excellent approach to full hands learning that keeps the user interested because they are following along in BobCADCAM creating the model and the machining toolpaths to make the model.

Even when they are done with the video, it can later serve as reenforcement when they are having a problem with one of their real world parts and can can refer back to the video.

Again, this must be a complex model that requires using all / almost all the tools in BobCADCAM. A video like this would generate sales and product loyalty and give the viewer a sense of accomplishment and pride that one does not get when they try and learn how a CADCAM system works by being shown how every menu command works.

On another Web Forum it was shown how even very simple parts being modeled and machined generated lots of interest / demand.

Imagine what a full blown "art to part" approach would do ?

Sorry to see you go! I got a lot out of your videos. One bad apple spoils the basket.

It appers there will not anymore good come out of thise thread anymore. If i wanted to get some complaining ahd arguing I would watch the soaps with my Wife.

Tjones and Sorin here is my main email kenlambert@valornet.com feel free to let me know if I can help in any way,

where are the videos? who made them. are they for sale or something? Please let me know

where are the videos? who made them. are they for sale or something? Please let me know

I have them if you can't find any way to download them. On the BobCAD Technical Support Forum I offered to burn the videos to CD's and mail them at no charge to one person who has downloading problems. Let me know if you would like me to do the same for you.

No charge for the CD's and no charge for the mailing.

jon

thank you for the offer. where can i download them from. it is nice of you to help us and make the videos. can you make a full set. i need to learn and this will help me. i do n't want to get in trouble with bobcad. is this a bootleg or is it done by you?
BD

There is no real way to cover all the features in one video. The concept is a good ideal but to do a video of this magnitude would not be productive. To do a specific video covering the part you posted before however would be good. It would not however come close to covering Bobcad's capabilities.

Since Bobcad does have more options than milling so there is no way to cover full features. Wire, turning, milling, laser, waterjet, and router uses are all in some way different and could not be covered in one video. A video to cover machining only still would be very massive if it were to cover all feature and the part would be too complicated to get thru on a dozen CDs. This much information would then cause a problem for anyone to locate and distinguish how to do individual operations. If anyone does not know this then they could not have used Bobcad for nearly what the users on the Bobcad sight are doing with it.

I have worked with Bobcad for a couple years myself and I have made some detailed parts. Some of the parts have taken 7 hrs to create with 1.5 millions lines of gcode. I am sure there are many other people who has done more than this but I use mostly solids and some pocketing.

An art to part video is available for the use of Bobart ProX.

BTW...If you own version 20 there is an update to 20.6 available.

Version 20 updates have addressed most issues with actual problems relating to errors reported. 20.6 is no different in this respect. Bobcad can be much better and no doubt it will be in the future. I however will not be one to harrass anyone to do what I feel is the right thing to do. I will keep requesting features that I feal are needed and I incourage everyone else to do the same in a constructive manner.

thank you for the offer. where can i download them from. it is nice of you to help us and make the videos. can you make a full set. i need to learn and this will help me. i do n't want to get in trouble with bobcad. is this a bootleg or is it done by you?

The videos were done by Sorin Nenu. He is a long time trainer of BobCADCAM and he does seminars on how to use BobCADCAM. While Sorin is not an employee of BobCAD he is their offical seminar person as it's BobCAD who schedules and handles the details of Sorin's seminars. The videos have no copyright and I guess you are free to do what you want with them. In my opinion you should not be selling them but giving them to others who wish to learn / know more about BobCADCAM. The videos fill a big void in documentation and in the other videos that BobCADCAM sells and were not done by Sorin Nenu.

jon

"I may have many faults, but being wrong ain't one of them." ... Jimmy Hoffa

As far as videos go the ones that Jon is offering are free to anyone. They may not be sold because they are produced by Sorin for Bobcad users. He has offered to freely make and offer for download.

If you wish to buy and sell then you should contact him. If you wish to do so send me an email and I will gladly send you his contact information.

Jon can freely give you a copy of any of Sorin's videos but there may be an issue if they are sold.

BTW. I am not a lawyer but was just trying to put into my own words what I was told.

"To do a specific video covering the part you posted before however would be good."

I don't think a specific video just covering the part I posted is necessary because it can be included in a more comprehensive video. The reason I put the screen shot up is because I have not seen it covered by BobCAD or by Sorin so I thought it would be a good thing to cover because Sorin was asking for input on what should be covered.

The part is actually the main part used in a tutorial for milling done by another CADCAM company. It's very quick and easy to do tapers and chamfers in their package. I've got some ideas of how I think BobCADCAM can make this process easier but I wanted to see how Sorin handled it before I posted my specific suggestions for better ways to handle tappers and chamfers on pockets and islands on the BobCAD Technical Support Forums.

"Wire, turning, milling, laser, waterjet, and router uses are all in some way different and could not be covered in one video."

I agree but I have not suggested that one video can cover everything. What I would like to see is modeling a complex part and then machining it with 2 1/2 axis machining routines. I would suggest a separate video for 3 axis surface milling and perhaps a separate modeling video for 2 axis wireframe and solid modeling.

"I may have many faults, but being wrong ain't one of them." ... Jimmy Hoffa

OK, i will buy them from jon so I don't get in trouble with bobcad. I will need a copy of the release to use so we can have them on network. I work for a big company and we do all this crazy paperwork to keep it legal.

They are not for sale and will never be for sale from me. They are a gift of me burning them to CD's and mailing them to you. As I stated, I don't feel they should be sold but rather given away.

"Thank you Jon for all your time and effort. I wish everyone was like you."

One of me is more than enough for some people. ;)

Send me an email with the address you want them shipped to and I will see to it that they hit the mail by Friday.

"I may have many faults, but being wrong ain't one of them." ... Jimmy Hoffa

Sorry but that is what I gathered from this statement.

I have posted this before but here it goes again.

In version 20 there are 5 types of pockets, spiral thread milling, profiling with aproach and depart, splines, facing, nesting, 12 types of surface creation, 5 types of solids, 3 types of booleans, 8 types of lines sketching, 3 types of fillet, skins, converting between 2d and 3d, 5 types of surface, text to vector, dimensioning, fitting text to path, driling,tapping,etc.. And who knows how many ways to change things like attributes, trimming, extending, break, divide, etc.

Also 20.6 has new nesting features as well. And like I said a single video would be way too long. However this could be done as a multiple video set. Say starting with cad drawing a 2D then converting it to 3d and so on. Simular to what Sorin now has but all based on the same part. This however may just be redundant work for Sorin and since no-one is paying him to do this I would bet it would be way too much to ask. I know you ask for Bobcad to do this but they most likely (like all other companies) would believe this is redundant and not wish to pay to have it done.

If you would care to do it then post some examples then maybe someone would buy them from you.

Without a doubt, modeling and machining a complex real world part is the best method of teaching someone how to use a CADCAM system that I know of. This is an excellent approach to full hands learning that keeps the user interested because they are following along in BobCADCAM creating the model and the machining toolpaths to make the model.

I agree with Jon on this point, and think it would be a great video to have. Combined with the V20 training videos, I think it would give us new guys a big step forward in learing the software.

Jon, what videos do you have, and are they available for download somewhere?

First off, I would like to thank Sorin for his willingness to assist BobCAD-CAM customers by creating additional videos. He is a professional and we appreciate his efforts and having him as a part of the BobCAD-CAM team.

The Version 20 Training Professor Video Series is the largest body of video training that the CAD-CAM world has ever seen with more than 170 individual videos covering individual and specific software functionality and packaged in a way that is not only affordable, they have proved to be very workable in trainingthe user. The primary objective is to offer a visual aid to specific functions rather than make a user watch a 30-40 minute video just so they can learn 1 function. The video box set includes a video index that does provide data regarding recommended videos to watch for specific things which do include solid modeling and the creation of toolpath for both simple and complex parts. These videos have helped thousands of users gain a better understanding of BobCAD-CAM Version 20 and opened the door to success. That was the objective and always will be for us here at BobCAD-CAM.

In the future, the BobCAD-CAM software user will not only have this type of video catalog, they will be able to view "start to finish" lessons that will support the constructive requests in this forum as well. This you can expect to see from us. We have also just launched a new program that offers one-on-one web-based training solutions as of today to further provide effective training solutions for the customer. This will ultimately solve the immediate need for answers. These individual training sessions can be video recorded for the user as well.

As for web-based downloadable training videos, we are working on providing you some solutions. We appreciate your patience and dedication to BobCAD-CAM.
Sincerely,
Chris Corbell
BobCAD-CAM

Chris,

This will be great, and I'll look forward to it. I agree that the 'Version 20 Training Professor Video Series' is a very good training aid, and a LOT of work went into producing it. I can't imagine trying to learn the software without it.

The amount of time we spent producing those videos was staggering. It took me approximately 3 months full time to get them finished. However, I also realize that things can be improved and made even better. When I wrote the Version 17 operators manual I was in sales not tech. I was embarrased at the quality of what we were giving users. That was 11 years ago I believe. I have written our operator manuals ever since. Every manual is better than the last as are the training video products. You learn and get better at what you do and we listen to what your customers say. The next series of products and training aids will be even better.
Chris

Chris,

Thank you for your input. This helps to answer questions for those of us who would not know any more than they are being told by others.

I have also done manuals for a company I supported and know the cost of producing them is very high. Detailed training videos, when done correctly, are also very difficult to get done. A mispoken word could cost several hours of time and starting almost over. Comes in handy to have a good audio editor. Also knowing that every upgrade and change in the software will effect the manuals and videos greatly, sometimes requiring the video be completely remade.

I am glad Bobcad and Sorin are working on making these type videos for actual part samples and will be glad to see them soon. It is always nice to see that some companies still listen and support the small users.

Tim

Jon,
Can you plase make some more videos for us. idownloaded the one on the site but we could use mre. since soren doesn't want to do it anymore, can you please, please help us and make some more of them. i really could use another pocket one with taper on the walls and islands. bobcad told that it is simple but i need to see it. can you please make one for me?
BD

Just to clear things out. Me and Chris at Bobcad know each other for long, long time and I know that he as well as me and everyone else at Bobcad, are willing to do what ever we can to help. Most of the time, we don't know what your needs are until is too late and you are upset...There is so much that a company can do. Can you get videos from Microsoft on how to create a simple folder????LOL. The video files that I have are not to compete with Bobcad by any means. They are additional tools that I create for the guys in my classes in the evening to help them when they go back to work. I have the whole colection of them. They are not rehearsed or anything and I apologize for that. I am NOT mad at anyone here (well except one) and I want to help (that was my intention to begin with) but it needs to be done based on what this thread was all about. So, in order for me to continue to participate and share the videos with you here are rules:

No more bashing Bobcad or complaining (create you own Bash Bobcad thread if you wish, remember this is about learning).

Posts from JB will be ignored by me and whatever he is asking for I will NOT do.

My commitment to you and Bobcad is to help at no cost to anyone so please be patient with me since my schedule and personal life makes time a very scarce comodity.

Here is what I have:
Environment settings
Tool bars configuration
Icon functions changes
Post processor tweaking/creating
Gasket part from my class example(rough,finish,chanfer,spot drill
drill andrough and finish 2 pockets)
Storing your G code, Setup pictures and setup sheet to the cad file (really cool stuff)
All this is already done but is going to be posted as individual files so it will take a while and they are going to be posted over time to give everyone a chance to download them
Best reagrd to you all,
Sorin (By the way JB- the files are copyrighted and I will have to issue you a release to do that or else.....)

Jon may have been using Bobcad for some time now but thats not making a video. I think Jon was actually needing a little help with that same style of pocketing not to long ago.

Actually maybe he could record for you how he did his job. I assume he got the job done so it might be easy to go back and record the steps.

How about it Jon?

BTW....Sorin, the Storing the Gcode one is what I posted in 2 files. I called it something like Using Bobcad in an ORganized Manner. It was really good and it took me a week and a half to post. Again I thank you for giving the permission to help you post them.

Tim,
I finally got my stuff together and I got some space on the net...long overdue. Anyway, I will have my site up and going in about few days and then the files will be there. It will be a password protected site so anyone that needs access will have to have a password issued by me at no cost to access the site. That way I can somehow control who gets there and who doesn't. Regarding your previous post, I hope that I get to see Jon's video also and hopefully we can all download it. How abot it Jon. Thank you in advance for it. How about you guys? Don't you want to see it? Please ask Jon for it, I am sure he has it and wants to share it with us.

Sorin has clearly said he doesn't want any of my help and will ignore all of my suggestions and input. Here is his quote from above:

"Posts from JB will be ignored by me and whatever he is asking for I will NOT do."

There is a reason BobCAD has the kinds of problems it has and why what is posted on www.practicalmachinist.com in the CNC Forum is posted.

BTW....Sorin, the Storing the Gcode one is what I posted in 2 files. I called it something like Using Bobcad in an ORganized Manner. It was really good and it took me a week and a half to post. Again I thank you for giving the permission to help you post them.


"I called it something like Using Bobcad in an ORganized Manner. It was really good and it took me a week and a half to post. Again I thank you for giving the permission to help you post them."

I burned Using BobCADCAM In An Organized Manner as well as the other videos to CD's and mailed them to those who requested them today.

Unfortunately, these files are copyright protected and sending them with out a written permission could mean that you broke the law. I will appreciate it if you could post your video file here to see how you did the file that you have posted. That way we can all learn new way of getting things done. No one person can know it all so I hope that you are going to post the video and give me the permission to show it in my class and pass it on to who needs it.
Thank you in advance

Still waiting for the video from Jon. Hope to get it this evening so I can show it tomorrow to the class.
Thank you in advance.

Sorin,
thank you for returning and continuing to share your information. I had been a user of another Cam system for ten years and switched to Bobcad after starting my own shop and found it hard to learn. The videos that you posted where very helpful. I have the version 20 training professor cd's, but found your short and to the point lessons much more useful.

Thank you for the kind words. Bobcad as the rest of the programs out there, requires some ime to learn and to get the feel of the way they do things. I am sure that you will do all right as long as you are willing to learn. I am sure that Jon's videos are as good as mine if not better. I am really looking forward to seeing them.

Just relized that I will have a seminar in Phoenix next week. I invite Jon (Phoenix resident) to please stop by the hotel and maybe share some of his experience with all of us. His videos will be probably a great help for all my trainees. Thank you in advance Jon.

"I have the version 20 training professor cd's, but found your short and to the point lessons much more useful."

Of course you did ! That's because it's not possible to learn a CADCAM system going though the every menu choices like the V20 Training Professor Videos do. In my opinion the current V20 Training Professor Videos don't teach someone how to model and machine with BobCADCAM at all.

The current V20 Training Professor Videos should be set aside and new ones done immediately that actually teach someone how to model and machine with practical examples. This is the approach taken by most CADCAM vendors and it has shown to be very effective.

With quality training materials many people do not have any need to attend a 3 day seminar on how to use their CADCAM program. Even complex surface modeling software like Rhino can be learned by most users with their Level 1 and Level 2 training .Pdf files.

I have a more simple 3D job I made using bobcad posted on our web sight. The mold insert is the one. I can not give out company files but the parts are modeled in Alibre.

http://www.indtools.net/

I have some really good ones like I showed you in class Sorin but I do not have permission to post it yet. That is the large extrusion die I had questions on about doing the full part in Bobcad. That one would make a pretty good sample for converting a 2D spiral pocket into a 2.5D path. You might remember the file you showed the class and the time would require an unattented run at night. Most of the people in class said they would never let their machine run with lights out.

If I can I will post the model of it on the web sight this week. I must get permission as out customers have certain rights to the designs.

Jon,

Do you have any jobs you did we can see posted. I will try to get a picture of the cavity to go along with the model to show the finished product.

Maybe you could show us some of your work. Is there a link to your company's homepage we can check out?

Bobcad could get a good ideal of what types of videos might work well if some of the users posted links or pictures of work that would be benificial.

tjones,

Good idea. While I don't have v20, sorry Sorin I'm still using 17, I have been a long time Bobcad user. I needed and still do need the ability to place a part in a position I want it machined at, regardless where that is located, and have the the cam software automatically rotate the part a minimum of 4 indexes on my simple designs and several more on the more complicated. I don't want to have to re-draw, re-orient or re-do anything. I offer this sample for anyone to show me if Bobcad v20.??? can do this. In 17 it is a long and tedious process of doing all those things I don't want to re-do, but I get really good code from it and accurate parts. I just need it simpler.

Mike

well I can't post it. zipped to the max it is still too big.
If any one wants to try this I will email the file (zipped) to them. It is a rifle stock.

I have a website with a few parts I did in Bobcad , the site is still being worked on but you can see a few simple parts.
www.lambertsrc.com

OK I posted a few pictures of the top and bottom of the extrusion die. The die again was designed in Alibre and the pretty picture is just easy to export from there even without the photorender option. I would have to do screenshots of Bobcad for the same effect but I was told these would be what I could post. The part is 24" long.

www.indtools.net then click pictures

I havent made a photo yet of the machined part because I will need to bring my digital camera from home. Anyhow you may be able to see the nice pocket in the back of the plates. They were done with Bobcad and the form on the other side was as well. Notice the pockets have a 3D contour and many islands.

How bout you Jon? Got any to show us yet? Would like to see what type of work you and the others here are doing.

Nice work Ken. I would like to have that type of stuff at home to do.

Some machine info would be nice. If Bobcad is to do this would it be a little like the nesting feature? I am just not sure yet what you are doing with the parts but is the program small enough to fit in your control?

I would like to see a little more about this and was wondering if a script might be the best way to handle it.

Hi tjones,

I have unlimited file size for the program but they mostly run 130,000 lines when done on Bobcad and somewhat higher than that on mastercam. I have attached some screenshots so you can at least see what I am talking about. I use a 4 axis machine that is way low tech by most of the standards but I can hold .015" over the length of a 32" stock. That's pretty decent considering I will make it much worse than that when it goes to sanding! :(

All these were made using my 4th axis machine. The blue one is a Bobcad v 17 program but still needs some tweaking due to the fact that 17 could not do surface cams. The little one in the fixture is also a Bobcad program that again needs tweaking. The finished walnut stock is made using Mastercam and was programmed for me by Dab here on the Zone.

Guys,
Have you noticed that JB keeps posting negative things and braggs about how much he knows but is ignoring our request of posting some of his work???

Sorin,
I for one appreciate your dedication to us new users of BobCad and hope that you continue to share your wealth of knowedge, I have only been able to see one of your AVI's and would like to be able to see them all, I have been a silent spectator on many forums and have noticed that no matter what forum we are members of there is always someone who is bored or lonley or disgruntled or just desires some attention.
Constructive critisizim(sp) is welcome on most boards however constant negatives posted by some on forums usally have no positive benefit to the poster or other members of the forum. I hope that these people do not deter you from the positive help that you have done on these forums.

Thank you
Mark

Any negative comments about someone else, and this thread gets closed. Final warning.

I could and should but wont!

Anyhow keeping on the positive, are there more actual users who will post some examples?

turmite,

Bobcad does not auto rotate parts when posting unless you can lay the part out as a flat form. Then you can convert the Y or X axis into a 4th axis move. This way the entire part is machined using the 4th axis during cutting with the one axis staying on centerline. This is normally done for round parts where a groove or text is machine around the circumference.

Your parts would be a little difficult to do this way so there is not a auto turn and cut as you would like. However what you would normally do in Bobcad is to post one side, use a script that will rotate the 4th axis. Rotate the part on the CAD window (this too could be done in the same script as the one adding the gcode to the program) and then generate the code again.

These things could be handled in scripts to make it pretty simple and just taking a few clicks instead of the manual work.

I have a "simple " example here....
one of two matching motor mounts I used BobCadCAM to prep for machining through Mach3 and a Shoptask. This(these) are for the slaved drive of my 3'x3' router project logged under the wood router log files here in CNCZone. These are designed to allow springloading of the pinions to the racks.
Many of the other parts that had to be made were also done with BobCadCamV19. Others just by writing them out. And still others using Mach3's features with the wizards.

"How bout you Jon? Got any to show us yet? Would like to see what type of work you and the others here are doing"

I'm sure you would.

The majority of work done in Phoenix, Arizona is for either Honeywell or the semi conductor industry. How do you think they would feel when I violated their non-disclosure clause and posted their proprietary designs on the web ?

Here are some carb throttle armes made with Bobcad and machined with mach2 on my home converted cnc mill, I also anodized them and I am just a beginer.

these are some carb adapters done in Bobcad with my home setup

this is a motormount as of know all my parts are simple but I am working on some 3D items.
