Abstract：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.
