Calculating Metal Removal Rates

The milling strategies for removing masses of materiel have changed dramatically through the advent of lighter duty machines with high torque motors, increased spindle speeds and table rates. However, the formula for determining metal removal rates remains the same. Multiply the depth of cut by the width of cut and the feed rate to find cubic inches per minute of material removed.
