基于双频激光干涉仪的重型数控机床定位精度测量

Measurement of Position Accuracy of CNC Heavy-duty Lathe Based on Dual-frequency Laser Interferometer

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 ex- plore the use of virtual test method and lay the foundations for getting the precision value.
