一、前言由于机械加工技术的发展,才有可能实现机器的高精度、高速度以及小型化,并对工业的进步作出重大贡献。同时,机器零件的形状也有日益复杂和小型化的趋势。与此相应地在现场要完成精密加工,因此,提出了高精度测量轮廓形状的要求。本文介绍的轮廓测量仪,是把照相机,聚光镜 I. INTRODUCTION Due to the development of machining technology, it is possible to realize the high precision, high speed and miniaturization of the machine, and make a significant contribution to the progress of industry. At the same time, the shape of machine parts is also increasingly complex and miniaturized. Accordingly, the precision machining is completed on site, and therefore, the requirement of measuring the contour shape with high accuracy has been proposed. This article describes the contour measuring instrument, is the camera, condenser lens
