Sorry for my poor english for it's not my native language. Does the MC8.1 can support KSR(Knowlage of Stock Recgnization)? I would like to millling a irregular shape and won't use the rectangular stock so that saving some time. But the MC seemed to generate toolpaths always use a rectangular stock when rough milling. The access ot stl files seems can only setup irregular stock in varify processing and not being used in generate toolpaths. Above founction can be found in Cimatron 12 and Powermill 3.0.11 whatever in generating toolpaths or varify it. If I have not learned how to use the KSR of MC V8.1 for I am a newbie in NC programming. Any ideal? I will very grateful if get your help.
