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.

Feed Rate and Speed Calculator . You''ve found our simple free online Feeds and Speeds Calculator that uses the classic formulas taught in shop class. With a calculator, you don''t need to worry about how to calculate feed rate for milling, or the speed (rpms) either. Just key in the parameters and our calculator will find the answer for you.
