一、前言数控机床的出现和发展解决了控制工件和工具间的相对位置,从而能加工复杂型面的难加工零件,同时,由于数控机床的自动化程度高,且可以通过改变程序来改变加工工艺,因而在中小批生产中对提高生产效率起了很大作用。但是,数控机床不能在加工过程中根据加工条件的变动而改变工艺用量,为保证零件质量,在程序编制时只能根据其保守的用量来进行加工。因此,不能充分发挥工艺装备的最大效能,对工件质量也不能监控。为此,发展
I. Preface The emergence and development of CNC machine tools solve the relative position between the control of the workpiece and the tool so that it can process difficult-to-machining parts of complex profiles, at the same time, due to the high degree of automation of CNC machine tools, and can change the process by changing the process , So in small batch production to improve production efficiency played a significant role. However, the CNC machine tool can not change the process consumption during the machining process according to the change of the machining conditions. To ensure the quality of the parts, the CNC machining can only be processed according to the conservative dosage when programming. Therefore, we can not give full play to the maximum efficiency of process equipment, the quality of the workpiece can not be monitored. To this end, development
