Hopefully some bright swiss "guy" can help me with this problem. On my Citizen M32, I am machining a part on front spindle that has two identical lobes 180* apart on the face of part, using the same tools for both sides of part, two 1/4" C. E/M's, one is ball nose, and I am running the same subs to machine and then profile the tips of the lobes. The material is 1.0" pre-heat-treated tool steel. The problem I can't seem to get past is that the same lobe on 25% of the parts that I machined, was .001 smaller (in Z) than the other one.
Like I said I am using a Citizen, with PartMaker CadCam programming, so that is a huge variance! (not to mention out of tolerance)
