基于球杆仪的空间误差测量分析方法研究

摘要

The detection of the error of NC machine tools have great meaningful to improve the machining accuracy. After analysis of the existing space measuring methods, the Renishaw QC20-W ballbar, a measuring instrument for measuring spatial circle movement error of machine tools is introduced. It can measure a typical machine tool' s position accuracy, acquire the overall value of roundness error and lay foundation for the implementation of the compensation of the circular trajectory error.%数控机床误差的检测对于提高机床加工精度具有重要的意义.在分析已有的空间测量方法之后,介绍了一种可用于测量机床空间圆运动轨迹误差的测量仪器—Renishaw QC20-W球杆仪,它可以创建典型的机床位置精度空间测量,获得总体圆度误差值等信息,为实施圆轨迹的误差补偿打下基础.
