触针式二维轮廓测量评定系统的改进

Improvement on Stylus 2-D Contour Gauging System

对触针式二维轮廓测量评定系统作了较大的改进:改进了测量方法和设备结构,提高了测量精度;设计了系统误差补偿算法,大大减小了由系统误差所造成的测量误差;提出了螺纹零件评定的新方法,简化了操作步骤,提高了评定结果的准确度;设计了轮廓对比功能,可将设计尺寸与被测轮廓进行整体对比,以判定被测零件是否满足设计要求。

The stylus 2-D contour gauging system is greatly improved. The device structure is designed newly for the modified measuring method, and the measuring precision gets much better than before. And the system error compensation algorithm is designed for reducing gauging error. A new thread gauging method is put forward, which simplifies the operation process and improves the assess accuracy. A new function of contour comparison is designed to assess the quality of the measured part by comparing it to another standard contour.
