It should work by using cutter comp. But I normally measure the endmill, plug that value into the CAM program, and compile the G code with the correct endmill size. Optionally make a test cut, and adjust the comp in the CAM program.
For some reason I wanna use macro programing for simple parts instead of CAM programs, for example I have a circular blank part that I wanna create a 20mm diameter hole inside of it with a 12 diameter endmill tool.Quote:

The height of hole is 15mm.
Sorry, I have no idea. I can't help with that.
...depends on the CNC control...and the programmer:eek::Quote:
