METHOD OF COMPENSATING INPUT FEED FORWARD CONTROL AND ITS APPLICATION IN THE GRINDING OF BALL LEADSCREW

Abstract

Abstract: In order to improve the accuracy of ball lead-screw grinding, a new method of compensating input feedforward control is used in the system of laser feedback error compensation for lead-screw grinder. Theoretical analyses shows that this input-revising algorithm can improve the accuracy and the transient response of the system. When this method is used in the ball leadscrew grinding error compensation system, the maximum error is effectively decreased.

Key words: Ball leadscrew grinding Laser feedback compensation, Input revising, FM-52M, Grain boundary carbides, Grain refinement, Inconel690, Pulse TIG welding
