Holder still gouging. What's the deal?

[andrewgore]

I'm roughing down an electrode. I'm at .400" stepdown with 50% stepover (12mm bull nose). Running at 1000ipm. My dilema is this. I am leaving .005" on wallsfloor. I have toolholder collision detection on. The tool if hung out at 1.375" out from bottom of holder, reaches everything fine and dandy.

 

Problem is that when running the .4" stepdown. For some reason mastercam can not recognize that this roughing operation doesn't clean up all the stock on the part. No matter what I do, I end up with a collision from my toolholder from this leftover stock. Any suggestions here. I've already toyed with minimizingmaximizing my stepdownadd cuts and all that to no avail. I've had this problem basically the entire time with HST's, but no solution.

 

PS, I've even tried lying to the thing and said my tool was hanging out moreless and it still will gouge the toolholder. I have also tried telling to stay from .010" away from holder, all the way out to .25" and I still get problems.

 

Thoughts? Suggestions?

Thanks

Andrew

I'll just add. I turned my toolholder gouge setting to stay away from holder .75" and it seems to be working now. Kind of ridiculous, but I guess it'll have to do for now.
