摘要
垂直度误差所引起的位置误差是机床空间位置误差的重要组成部分。提出利用单头激光多普勒位移测量仪及平面反射镜,通过测量机床的4条体对角线的位移误差实现对机床三轴间的垂直度误差测量。实验结果表明,采用该方法测量垂直度误差快捷、方便且准确,可对任意大小的机床进行测量。
The volumetric position errors caused by squareness errors among the three axes play an important role of the machine errors.It is difficult to align and time-consuming to get squareness errors with conventional laser interferometer,described here is a new laser measurement technique based on a single-aperture laser interferometer, described here is a new laser measurement technique based on a single-aperture laser Doppler displacement meter with a flat mirror. And squareness errors are determined efficiently by measuring displacement errors along the four body diagonal errors. The experimental results show the method be feasible and accurate.

laser Doppler displacement meter Abstract： The volumetric position errors caused by squareness errors among the three axes playan important role of the machine errors. It is difficult to align and time--consuming to get squarenesserrors with conventional laser interferometer, described here is a new laser measurement techniquebased on a single--aperture laser Doppler displacement meter with a flat mirror. And squareness er-rors are determined efficiently by measuring displacement errors along the four body diagonal errors.The experimental results show the method be feasible and accurate.
