Moreover, if I had machine model in CAM, tool offset compensation would not be nesessary, CAM would do those calculations. That is, in my case the machine does RTCP transformation <https://infosys.beckhoff.com/content/1033/tccncprogramming/Images/image40_242.png>, but CAM does tool diameter compensation. ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
