Collin, it’s a Robodrill, 5 axis , with a Fanuc control. Temp is about 72deg. im using a .047 flat end mill. With shrink fit holding from pioneer. code is 5axis, G68.2 I’m not filtering, and the total tolerance is +\_.001”. overall size of the part is about 2x3x.5” and we bought the machine from Methods coincidentaly.

I’ve been working with a part for weeks now where the walls are drafted at .6 deg, and the walls are .1775 high. The walls form teeth for a wave guide. I’m using opti rough to take the cavity down to .020” remaining, then a swarf mill operation to finish the walls. The problem is, the simulation shows the part to be perfect, but the physical part is over cut by .005. I have a +\- .0005 tolerance and I can’t figure out how what’s wrong. Anyone have any suggestions?
