Abstract

A material forming machine comprising a forming tool driven by a forming tool motor, a workpiece, a feed drive motor, a sensor, and a reference signal, wherein said sensor varies the speed of the feed drive motor by responding to variations of the speed of the forming tool's motion, and wherein the reference signal remains constant. Said machine performs sawing, shaping, milling, drilling, hammering, shearing, chiseling, and cutting on irregularly shaped workpieces, having variations in density.
