Method

Calculate theoretical turning material-removal rate from a radial depth of cut, feed per revolution, and cutting speed.

MRR = ap·f·Vc

Don’t

This is theoretical steady turning removal rate from user-entered depth, feed, and cutting speed. It excludes parameter selection, diameter variation, approach/retract, interruptions, insert geometry, tool wear, coolant, power, rigidity, chip control, machine limits, tolerance, surface integrity, and process qualification.
