在使用加工中心、数控铣床等数控机床进行铣削时,常常会发生过量切削。过切,尤其是在精密加工中已成为一个亟待解决的问题,有时就因过切而使零件报废。产生过切的原因是多方面的,它不仅涉及到工艺方法,而且还涉及到数控系统的功能、数据处理速度、有源信息的储备量、机床的运动特性等。 In the use of machining centers, CNC milling machines and other CNC machine tools milling, often over-cutting occurs. Overcutting, especially in precision machining, has become an issue to be solved urgently, sometimes causing scrapings due to overcutting. There are many reasons for the over-cutting. It involves not only the technological process but also the functions of the numerical control system, the data processing speed, the reserves of active information and the kinematic characteristics of the machine tool.
