Milling Horsepower Calculator

The horsepower required for a cutting operation depends upon the material removal rate (or metal removal rate) and the unit power, which is a material property describing the amount of power required to cut that material. The horsepower calculator will display the horsepower at both the spindle and the motor and calculate the spindle torque for a given spindle speed (RPM). The motor horsepower required for the cutting operation can then be compared to the horsepower capability of the machine.
