Rotate C-axis while Vertical Mill spindle head stationary

[MS3]

Hi all

 New to MCam and hoping to get some help on a simple problem probably.  I have a Veriaxis i800 neo and trying  to do a profile cut around outside diameter of material with the c-axis rotating and the spindle head stationary.  I can get it to work with all axis moving but I hit soft limits on the machine when it is running.  Run out of room on the x-axis and a have plenty on the y-axis. I attached a sample of what I am trying to accomplish. Would do it in a lathe but there are many other features not shown that require it all done in one setup.

Thanks for any help

I don't have experience with this machine, but did you try rotary axis positioning for rotation type rather than 3 axis?

How is the post configured? Have you been able to use the C axis and get the post to output the code correctly? If the post is not configured to support that then that us something you have to go back to the post builder and ask to have supported. I would expect to See one X and Y move to the position then the Table Spin. If that is not the case then the post doesn't support it. Another option is try Curve 5 Axis and see if you can get it to do what you are after.

Need to add an Axis combination to the existing one to get this trick to work. It might work with your existing post. Only have the rotating table not the tilting table in the Axis Combinations this will sometimes trick the post to output the C like you need with having all will not.

Then in the operation make sure to pick this axis combination. I normally name one 5 Axis and the other 4 Axis. You can even have a 3 Axis one if you want.

The MMD and post I tried this with gave me the following warning when trying this with your correctly defined Contour toolpath.

ERROR - POLAR INTERPOLATION NOT SETUP FOR THIS MACHINE CONFIGURATION

Which takes me full circle back to the Post needing to being configured to support this type of work on the machine.

I ALSO WANT TO THANK YOU FOR SHARING A FILE.

Sorry wanted to make sure others heard me yelling that to them when asking for help without even attempting to come up with sample if they cannot share the file they need exact help on.

No problem on the file sharing, hard to help with out all information.

I tried the rotary axis positioning and it just moves the x and y around no rotary.

Also tried multiple axis combos like you showed and post out x and c rotary movement all the way around with an error for Y prompt. When post with all axis it post out correctly, just  X and Y move around while C-rotates 360, but it just limits out on X cause part is larger.

Output correctly and works on machine just not way needing it to 

Is there a way to tell Mcam to engage material on x and y hold position rotate C-axis then disengage or is that all in the post?

Have you tired moving the start point to different quadrants? If you share a Z2G then I can look at your post and see if there is a setting creating the issue.

Yes tried moving start points.  I was able to manually delete the x and y after engagement and get it to work that way. Still would like to now if it can be done in Mcam without have to modify program.

I would send this to your dealer and see what they can do to help get this issue addressed. This is their standard post from what I can tell.
