A method of controlling a cutting machine to cut workpieces according to the machinability of the workpieces includes the steps of providing a plurality of predetermined constant voltage outputs, each constant voltage output corresponding to a predetermined cutting speed for the cutting machine, selecting one of a plurality of constant voltage outputs in response to a desired workpiece material to be cut by the machine, and driving the cutting tool at a predetermined cutting speed corresponding to the desired material to be cut in response to the selected constant voltage output.
