  • Material directory-spindle speed and feed rate calculator
    Patent number: 6438446
    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. Alternatively, a second embodiment of the present invention would include a programmed memory provided with the surface foot rating of a plurality of materials. Once the type of material, the type of tool operation, as well as the diameter of the cutting tool is inputted into this embodiment, the proper RPM speed of the spindle would be determined.
