Iterative pre-compensation scheme of tracking error for contouring error reduction

Contouring errors calculated from the tracking errors of the individual servo drives is one of the important factors that affect machining accuracy. Through the pre-compensation of the tracking errors the contouring error can be reduced. This paper builds the prediction model of the tracking error,...

Description
Summary:Contouring errors calculated from the tracking errors of the individual servo drives is one of the important factors that affect machining accuracy. Through the pre-compensation of the tracking errors the contouring error can be reduced. This paper builds the prediction model of the tracking error, based on which iterative pre-compensation scheme is proposed, to achieve the optimum pre-compensation value without running servo drives repetitively. Simulation and experiment results verify that the tracking error can be predicted accurately by the prediction model and the iterative pre-compensation scheme of the tracking error can reduce the contouring error effectively.
