1.前言近几年来,机械系统的自动化有了快速的发展,实现了通夜无人操作的机械加工,因而在工件的测量方面,也正日益需要从人工操作发展到自动测量。在采用激光的柔性生产综合系统这一国家研究项目中,研制出了一种高精密度测量仪。这种测量仪可进行工件的自动测量,并且在整个生产系统中,不起机床的作 1. INTRODUCTION In recent years, the automation of mechanical systems has been rapidly developed, enabling the machining of unmanned vehicles in the middle of the night. Therefore, the measurement of workpieces is also increasingly in need of development from manual operation to automatic measurement. In a national research project using a laser-based flexible production integrated system, a high-precision measuring instrument was developed. This gauge can be automatic measurement of the workpiece, and in the entire production system, can not afford to machine for
