Again I am back to looking at tabs for SC. One of the reasons I started trying BobCad. I am trying to mill several small parts, but really do not want to take the time to create fixtures or soft jaws. really not needed as they are simple 2D designs.
I never got any of the suggestions before to work on creating tabs in SC. Anyone had any luck simulating them?
I did read a post (lost it) where someone created 2D circles and then had SC ignore them, but I never could figure out how to do that.
Any suggestions would help.
I do have the option of adding tabs in Alibre as a alternate configuration, but sometimes I am not sure how I will machine it when I am designing the parts.
Actually you mentioned some words i missed on the other post. I see how this can work now.
Only problem is I do not see a restriction zone in 2D contouring?
99.9% sure there is. I do 2D contouring all the time and create tabs that way. Im not at my CAM computer now to post a pic, but look again, I know its there.(or Im goin nuts )
You can also extrude them as fixtures. There is another way of doing this. Instead of 2D contouring use "Jet Cutting" . You can add bridges in this operation, however you will have to add a Z depth and a correct spindle speed using a editor (notepad++). I have done this several times and it works well. I have an active request for SprutCAM to add the bridges to 2D contouring.
You also mentioned in another post about editing the G-Code. Just to give some input for me I do programming(as well as design) and after looking at 1000's of lines of code all day, when I get home the last thing I want to do is look at G-code and edit code. I rely heavily on the simulation as I have limited time to turn a part around, sometimes literally hours. I realize some may find that interesting and challenging, but I have to many programming languages to try and learn more.
I will look into fixtures and importing that way. But sounds like perhaps SC will add bridges or tabs in the future. That can save a lot of work for people doing rapid prototyping.
Well, welcome to the wonderful world of CNC machining. Theres not a CAM software out there that won't require some good ole' G-code editing form time to time. I have used $30,000 CAM systems that needed tweaking on occasion. As a side note, using Note pad ++ makes it very easy to do simple G-code editing.
I remember going through a similar exercise a couple years back when I first got my mill. At the time I was importing DXF files and wanted to do tabs similar to the breakout tabs used on printed circuit boards (panels). I found two solutions, best I can remember.
First, I created a rectangle object and inserted it in my DXF files where ever I wanted a tab to be located. I then used the 2D contour routine to mill only the contours outside of the newly inserted tab object.
Second, I messed with fixtures except I could not get them to work with DXF imports. To get the fixtures to work I needed to import as an igs format and then treat the machining process as a 3d operation.
Surely there is a better way so I will be interested in seeing response here.
PS: I also do software most days and don't like hand editing my mill projects. But with that said I am slowly learning G-code and have been able to make minor changes as needed. Guess it's part of the game....
