Chipload Per Tooth Calculator

IPM / (Z x RPM) = CPT

This calculator determines the chip load per tooth, a critical metric in milling operations that represents the amount of material each cutting tooth removes per revolution. By factoring in key parameters such as feed rate, spindle speed (RPM), and number of cutting edges (teeth), the calculator provides a precise value used to optimize tool performance, surface finish, and tool life.
