科学技术的发展对加工和测量提出了越来越高的精度要求,靠提高机床和仪器的制作精度有很大的局限性,即使可能,在经济上也要付出高昂的代价。误差修正技术为解决这一困难开拓了新的前景。 按误差测定与实际运行的时间关系,可分为实时修正与非实时修正。按误差数据的储存与修正方 The development of science and technology has raised higher and higher precision requirements for processing and measurement, and there are great limitations to improving the precision of machine tools and instruments. Even if possible, it is economically expensive. Error correction technology has opened up new prospects for solving this problem. According to the measurement of error and the actual operation of the time, can be divided into real-time correction and non-real-time correction. According to the error data storage and correction side
