OK....here are the assumptions I am making:
1) The max # of flutes on an endmill would be 4 (perhaps this is wrong?)
2) The maximum chip load (roughing) is .005"
3) The maximum RPM for an X3 is 2000 RPM
So....the formulas are:
IPM = RPM x IPR
IPR = Chip Load x Flutes = (.005" x 4) = .02"
Therefore:
IPM = (2000rpm) x (.02") = 40 IPM
So why should my cnc mill be capable of 100ipm + ?
What is a good maximum limit for IPM on an x3?
Thanks!
