Hi, I am relatively new to Mastercam and was hoping you can help. I am using Mastercam's High Speed Machining Area Clearance Roughing toolpath to clear out a large angled surface. The tool I am trying to use is a 3" indexable carbide facemill (the tool is capable of ramping). I just got the tool, but from my initial experimentation with it, I can only run it at a depth of cut of 0.006". Much more and either the spindle stalls or it breaks an insert.
My problem is, that when I set the Z stepover value to 0.006", Mastercam takes an extremely long time to calculate the toolpath, since it is calculating a million little passes. I haven't yet gotten it to calculate completely as after the 45 minute mark, I've gotten disgusted every time and restarted the program.
Am I doing something wrong? Should I be using a different toolpath for roughing with high feed / light depth of cut tools?
Thanks for your help.
