【摘要】 数控机床的检测与修正是机床行业中的一个关键组成部分 ,每个国家都有相应的测量数控机床几何位置精度 ,特别是静态几何精度的标准。由于工件是在动态的过程中进行加工 ,数控机床的静态精度并不能完全代表其几何位置精度。对于某些精密加工和高速加工场合 ,必须对数控机床进行动态测量补偿。本文介绍了一种动态测量数控机床位置精度的系统 ,并给出了一些动态误差的实验结果。更多还原

【Abstract】 Measurement and calibration of machine tools are essential operation in machine tool industry and each country has its own standard to evaluate the performance of CNC machines, especially the geometric errors of machine tools in a static or a quasi-static state. However, the static geometric errors do not represent the total geometric errors as the parts are machined when CNC machines are in a dynamic state. Measurement and calibration of dynamic geometric errors of machine tools is necessary for some precision applications. Here in this paper, a system that is used to measure dynamic geometric errors of CNC machines is introduced and some significant differences between static geometric errors and dynamic geometric errors are given.更多还原
