A study on contouring motion control of machine tools

First Report: Analysis of Dynamic Motion Error

Abstract

In our research, we analyze the control methods to obtain high accuracy synchronous motion in feed-drive system of machine tool. First, we investigate how to define contouring motion error for error diagnosis. Second, the influences of the command and control characteristics on the dynamic contouring errors are analyzed by using motion error traces. Then, a diagnosis method with the square motion is proposed and carried out on the experiment.
