Milling Horsepower Calculator. Calculate the horsepower required for a milling operation based on the feed rate and depth of cut, which are used to determine the material removal rate (or metal removal rate). Also required is the unit power, which is a material property describing the amount of power required to cut that material.

The motor power increases with RPM at a similar rate to the preload losses which semi-cancels out to give a net power at thet tool of around 150-200W. I calculated torque from the RPMs and power. The motor seems to have good low end which drops off to a relatively consistent ~8in*lb; This mill is wimpy and I need to fix the power at the tool

The tractive pull multiplied by the drive pulley radius will give you the load torque. There is no short cut for deciding the load torque. This cannot be calculated from motor side. 5) Having decided the load torque, you can decide the required power at motor shaft, available motor size, gear ratio and so on.
