为解决高精度平面的测量提出了平直度光电组合测量法 ,北京机床研究所开发了ＰＧ - 1高精度平直度测量系统。该系统主要用于被测面能导电的中等尺寸工件的高精度平直度测量。系统采用双频激光直线光轴作为参考基准 ,进行单一线的连续非接触测量。通过若干测量线的相关检测构造?
In order to solve the problem of high - precision plane measurement, a flatness photoelectric combination measurement method is proposed. Beijing Machine Tool Research Institute has developed the PG - 1 high precision flatness measurement system. The system is mainly used for the measured surface can conduct medium-sized workpiece of high-precision straightness measurement. The system uses dual-frequency laser linear optical axis as a reference, a single line of continuous non-contact measurement. Through a number of measurement lines related to the detection structure?
