    Tool changes/ Taig mill

    Greetins all- I am a newby- if thats not obvious.. anyway- I am curious how you change the tools when prompted= without loosing your reference to home.


    I have also searched- and cant seem to find specific definitions to the following..

    I am so embarrassed to ask this too..

    Flute diameter
    shaft diameter

    there were others, i dont recall at the moment. But any info on tooling- or a point toward were to obtain that.. would be super appreciated.

    I Just cut my first piece and it turned out well. But im sure it could be better. Some of the details were not cut and i assume its because i did not run the pencil tool path that meshcam offered... but again, i did this because i didnt know how to change tools..

    thanks in advance=

    Humbly

    Keith

    Smile Rapid Changer

    Keith,

    If you want a quick tool change solution take a look at the Rapid Changer.

    http://www.hightechsystemsllc.com/rapid_changer.html

    You would preset all your required tooling in individual holders and program tool change stops in your cam software.

    Hoss2006 also has a very kewl Power Draw Bar and Quick Change however it is not for the Taig spindle.

    **********Cave Man Solution************

    If your tooling is close to the same length you can set Z zero with the first tool then when you are ready for a tool change remove the first tool, insert the new tool loose in the collet "So the tool will slide in the collet without force". Lower Z axis slowly until it reaches Z zero then tighten collet.

    If the tools are longer be careful you don't bottom out before hitting Z zero.

    *********************************************************

    Using built in Mach3 software technology:

    1: Setup Home / Limit Switches
    2: Setup Auto Tool Zero
    3: Use Auto Tool Zero After Each Manual Tool Change

    There are many ways to solve your dilemma, others will chime in with better solutions.

    just to clarify-

    You have your endmill in loosely, holding it in with one hand
    you tell your z to go to 0
    you "drop" the endmill so it rests against the table
    you tighten it up
    you go to home

    Sounds like a good effective way thanks for saying that as i also had a similar question as the OP.

    OP- tormach tooling is also pretty neat- it holds your endmill without the endmill sliding while storing, (er- can't put words on it) but it requires you to only zero it the first time, then you can just swap them from there on out

    cheers

    I dont think he is wanting a automatic tool changer. It sounds like he needs to know how to stop the program at the point he needs to make a tool change. And then how to restart it back where it left off.

    Teyber12's detailed description is very good!

    Your Taig is running slower than what?

    If you compare it to a machine with more aggressive screw TPI it probably looks slow.

    The Taig has 20 Turn Per Inch screws on all axis.

    The reasons:

    1: Very accurate resolution
    2: Allows the use of low powered inexpensive stepper motors and stepper drive.
    3:The Taig is designed to mill metal, the feed rates for metal with small tools are a lot slower than a wood router with a high speed spindle.

    The Tormach quick change tooling system is also nice, I am not sure which one would be used on the Taig.

    The flute diameter is the tool cutting size. (See A on attached diagram)


    The shaft diameter is the shank size. (See C on attached diagram)

    Keith,

    What kind of tooling are you looking for, what are you cutting?
    What inside corner radius do you need?

    A very easy way to rapid tool change by hand is to go to the hobby store and get the tiny little locking shaft collars used to hold wheels onto R/C aircraft. They look like your typical shaft collar, but are really thin and tiny so they can fit small diameter tools, and have a setscrew that uses an included allen wrench that looks like a sewing needle!
    These come in common sizes down to even 1/8", so you can use them to preset all your tools, even the smallest ones. They are reuseable indefinitely and only cost a few bucks for a whole pack of them.

    The trick is to use the above method mentioned a couple of posts back to get a tool to protrude from the collet a given measured amount, then you slide the little shaft collar up the tool as far as it will go until it rests firmly against the collet. Tighten the screw. Now when you remove the tool, it has a firmly mounted stop ring to index it the next time you use it. Every time you go to install that bit again, it will be in its pre-measured position everytime. Do all of your tools to the same set of known heights and it makes life really easy to swap them mid-cut or if one breaks.

    I watched those videos, and yes, you should be moving that fast with your Taig. Also, you should not have your machine stalling when going faster than 2 IPM, nor while cutting in wax.
    I was serious in the other thread, you need to get Mach configured right first before you do anything else. No matter what some people might think, 2 IPM is >not< normal.

    If I remember correctly, Deepgroove used to just use straight Xylotex boards in a simple unmarked box with 24v supplies and unmarked black motors of around 270/oz rating. Is this still correct? If so, I can look up the specs for optimal settings for the Xylotex setups. Its been years since I've used one of those boards but I still have a few config files saved for them for use with Taigs, I think even one for a Deepgroove machine like yours.

    Thanks for all of the replies, guys.

    My collet/bit seems to have a tight tolerance and i dont know that that would work. Perhaps i should investigate this further. Maybe im using the wrong collet.. I am using .125 endmills.

    and just as i suspected// flute diameter/shaft diameter.. exactly what i thought.


    StepperMonkey-
    I just looked at my mach3 setup= I was able to run well over 2 IPM last night. I reduced my motor velocity and accelleration in the motor tuning section.

    Before, i had it up around 33 for velocity... and i took it down to 12.498 for velocity and 2 for accelleration. Now it runs easily at 4.5 IPM.. and if i over ride that= it goes faster. But it is still slow. Not like the machines on the vid.

    As far as i know, yes.. they are like 270 or maybe 280 oz motors.. and the rest-- is out of my realm of info.. LOL


    My newest issue- the tool change, is the one that is holding me back- well.. im sure the setup could be tweaked too.. but at the very least i was able to cut my first part out- so i have some sense of accomplishment. The part looks rough, and i think this is because i used a flat .0625 endmill to cut it out. My theory is that a ball end mill would run this much smoother.

    I also did not do the pencil finish- so i am assuming that if I did, it would have cut the details around the center better? I have a lot to learn. i probably dont have my tools set up right either because you can see around the base where it looked like it double cut... This was why i asked about flute dia. and shaft dia...

    these are the tools i have.. and i just ordered a few more.. Try doing a surfae clean up on a black of freshly cut wax with a .125" bit.. mind numbing..

    here is a pic of what i got now.. not terrible for day 3 on this.. and the first attempt at drawing something with Rhino... (last time i drew something, it was 11th grade CAD (1996)
