I am programming helical rotary compressor impellers using esprit, the composite mode works fine for standard milling but I would like to force the machine (okuma multus) to polar interpolate with the head at a tilt while swarfing a profile. I can extract curves from the part surface and use them to drive a tool in wrap mode which gets me from end to end in one c-axis line of code, but using this method has severe limitations. Esprit does not recognize where the part is (could possibly live with that) and I have no control for flank engagement or tilting of b-axis head. Is anyone aware of a cam application that is capable of meeting these requirements?
