5 Axis deburr and gouges?

[crazy^millman]

Has anyone run into issues with 5 axis deburr and getting gouges when posting the code? I suspect many different things here, but trying to go down my list of things to rule out.

#1 would be no one ever having a problem and always getting perfect code when using 5 Axis deburr. That would mean even changing from a .004 to .005 edge break and still getting good error free code.

#2 is going to be I have a VMC from Vericut that is not setup with correct kinematics and have to do some testing on the machine to see what is reality and what is not. No time for that and had to 3+2 one operation into 12. 

#3 has been ruled out and that would be a posting issue. I posted code from 4 different posts for the same machine and all of them were within .0001" of each other. All the angles matched perfectly out of the different posts. If the post code is wrong it would fall back to the NCI coming out of Mastercam. No time to start digging into that can of worms. 

I took the time and made a .01 Edge break model to use in Vericut. Yes that took me 2 hours and some creative CAD work to make it happen, but yes every chamfer on the model is .01 that I am machining. I saved it out of Vericut with a .0002" tolerance to avoid bad STL triangles. I even broke the reference turning it into a .ply file for Vericut and that all looks good on that side of the process.

I get gouges and sometimes the cutter will just take out a wall.  I do see this in verify and fix by breaking up edges in separate paths.

Breaking the path into smaller groups of edges is how we've handled it here as well.

I've had this problem, and I believe it was related to tolerance (which I see you already have quite low) and maybe clearance.

Tracked this one down to a bad Vericut Machine Control. Once we got that corrected all the gouges went away in Vericut. I lost 20 hours fighting this issue, but I am finally happy to have an answer.
