APPARATUS AND METHOD FOR PRECISION GEAR FINISHING BY CONTROLLED DEFORMATION

摘要

An apparatus and method are provided for the thermomechanical net shape finishing of precision gear tooth surfaces by controlled deformation into the metastable austenitic condition. To this end, an arrangement of a fixed axis through-feed motion of workpiece and moving axes in-feed motion of two opposed rolling dies are utilized. By means of process control methods and architecture for accomplishing precise mechanical motions, thermal and environmental control, and timely and automatic transfer of workpieces, high strength and high accuracy gear tooth surfaces can be produced.
