基于双频激光干涉仪的重型数控机床定位精度测量

摘要

采用激光干涉仪对重型数控机床纵向上两段位置定位精度进行测量,得到目标位置点的定位精度和重复定位精度,并对试验值进行了分析,为探索利用虚拟检测方法得到全程精度值打下一定的基础.%The dual-frequency laser interferometer is used to measure the position accuracy of two sections in the Z axis direction, in order to obtain the position accuracy and repeatable position precision of goal points. Then, the experimental data is analyzed to explore the use of virtual test method and lay the foundations for getting the precision value.
