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 values of power calculated by the previous formula represent the "theoretical power" required for size reduction. Actual powers can range from 2 to 20 times the calculated figures. Example In dry crushing of limestone, lumps of 50 mm size have their size reduced to 10 mm. Estimate the theoretical power required for a feed rate of 20 ...
