Rough Milling Speed vs Power

The same end mill that one would use for a conventional power approach can be used productively for most high-speed roughing applications There is a tendency to use end mills with five or more flutes for high-speed roughing but operators should beware If the machine is not reaching the programmed feed rate the additional flutes will have a negative impact on tool life

Spindle power and torque limitations

2012/5/1The power is approximately proportional to the metal-removal rate so the power curve places a fundamental limit on the mrr In both instances there is little power available at low spindle speeds While the instantaneous power may exceed the limit (for a short time the spindle acts like a flywheel) a cutting power greater than the available spindle power causes the spindle to stall
