mach mill cutter compensation
« on: November 30, 2013, 10:35:29 AM »
Hello everyone. I wondered if anyone could help me. I'm using my milling machine for simple things at the moment. I use   featurecam to produce the code. If I get II don't use cutter comp mach will follow the programme no problem. if I use cutter comp I have certain issues.

The above code is for machining a 1/2" hexagon with a 1/4" slot drill. On the last side to be cut the machine stops short abd then proceeds to cut at an angle to the last position.
The following code is the same but with a couple of modifications but does the job how I want it. So the question is, is the cadcam giving out the wrong code or is mach not reading the code as it should

The following  programme is to cut a circle .3" diameter with 1/4" slot drill but with the comp mach comes up with a message saying arc radius not less then cutter radius. other than using a smaller tool which isn't always a good thing is there anything I can do to rectify the problem or is this just how mach is. Do machines with Haas Or fanuc etc. have this problem

I don't know  / use Feature Cam , but, you should be using a post processor provided by Feature Cam  for Mach.
