CNC Feed Rate Calculator
The free CNC Feed Rate Calculator answers one question: Feed rate from RPM, flutes and chip load. Enter your numbers in inches or millimeters and the result updates instantly in your browser, with no sign-up and no app to install. Use it on your phone at the bench, then copy or print the result for your cut list.
Typical chip loads in hardwood are 0.004–0.010″ (0.1–0.25 mm) per tooth for ¼″ bits.
