In recent years,precision measurement technology has developed rapidly with gratifying results.For example,the online measurement technology can display the processing status in real time and detect whether there is any abnormal situation in time,which can greatly improve the production efficiency.For machine tool control devices,high precision,low cost,and miniaturization are required.Because the components such as automobile engines are required to have very high precision in order to reduce noise,prevent environmental pollution and save energy,these are the urgent requirements of the times for the manufacturing industry.
近年来,精密测量技术发展迅速,成果喜人。例如在线测量技术,已可进行加工状态的实时显示,及时检测是否出现异常状况,从而可大幅度提高生产效率。对于机床控制装置,则要求高精度化、低成本和小型化。因为诸如汽车发动机等均要求其组成零部件必须具有非常高的精度,以便减少噪声、防止环境污染和节省能耗,这些都是时代对制造业提出的紧迫要求。
