车床的定位过程不象镗床那样不进行切削加工,因此车床的定位过程变速必须平稳,为此车床的位置控制系统一定要解决好这样一个关键技术——定位方法。众所周知,数控机床是靠程序进行工作的,人们在编程的过程中不可能把加工过程中出现的,影响加工质量的参数统统编进去,因此自适应控制(AdaptiVe control)就成了保证数控系统具有最大的加工效率、最低的加工成本、最佳的加工质量的一种切实可行的手段。 Lathe positioning process does not like boring machine that does not carry out cutting processing, so the lathe positioning process must be stable, for this position control system lathe must solve such a key technology - positioning method. As we all know, CNC machine tools are based on the program to work, people in the process of programming can not appear in the process of processing, affecting the quality of the parameters are compiled into the whole, so adaptive control (AdaptiVe control) has become a guarantee CNC system has The largest processing efficiency, the lowest processing costs, the best processing quality of a practical means.
