Difference iteration method of tool arc <italic>Z</italic>-direction compensation for stabilizing <italic>X</italic>-axis

Abstract

：This paper proposes a difference iteration method based on slow tool servo technology to accu• rately determine the Z-direction of the tool arc as well as the compensation in planning the free-form sur• face tool path. Further，the proposed approach aims to reduce the tracking error caused by the inertia of the X-axis and hence improve the cutting efficiency. First，the polar diameter of the ideal tool point is com • pared with that of the actual tool point，which is calculated from the given tool contact，to determine 文章编号 1004-924X (2022)05-0594-08 收稿日期： 2021-05-31； 修订日期： 2021-07-30.
