ABSTRACT:
A programmable command module for inputting a surface foot rating parameter into a device for controlling the spindle speed of a cutting tool. Based upon the surface foot rating, the proper speed of the spindle is determined with respect to a particular cutting tool parameter, such as the tool's diameter. The spindle speed setting is transmitted to an AC inverter which in turn controls the operation of an AC motor for rotating the spindle at its proper speed.
