Feed Rate Calculator

IPM / RPM = FPR

This calculator helps machinists and CNC programmers determine the precise feed rate per spindle revolution for turning, drilling, boring, and tapping operations. By inputting the feed rate or inches per minute (IPM) and spindle speed (RPM), the calculator outputs the optimal feed rate—ensuring efficient material removal, improved tool life, and superior surface finish.

This tool eliminates guesswork, helping optimize machining parameters to prevent tool wear, reduce cycle time, and enhance machining accuracy.
