G13 Circular pocket and cutter comp??
« on: December 12, 2008, 05:34:59 PM »
Is there a way of getting Mach 3 to understand cutter comp in a G13 circular pocket move?

If I run the code as follows for a 20mm diameter pocket and using say a 10mm cutter, mach ignores the D offset and thus produces a 30mm pocket!

G13 I10. D3 F200

This is how I would usually programme the circular pocket on my Haas (which obviously understands cutter comp completely!)

So does anybody know a way of utilising cutter comp in a G13 pocket cycle, or do I have to allow for it in my programme? ( Which is a pain in the A@@e when doing limited pockets!)

Thanks, Roy

Ah, I was wondering about this one as well. Not just the cutter comp, but the rest of a G13 canned cycle; G13 I6. K10. Q2. F200., to follow your example. Tool stepover and a finish cut are often quite useful.

Cutter comp is getting a work over right now so things should be much better very soon.
