一、引言我国独创的高速走丝电火花线切割加工已经作为比较成熟的加工工艺广泛地应用于生产实际当中。如何提高高速走丝线切割机床的加工精度以满足模具和特形零件的要求,越来越被国内同行们所重视。近年来,通过对高速走丝线切割工艺规律的研究,已普遍认识到除了机床设备、控制器的精度、脉冲电源及工作液的性能以外,电极丝振动状态 First, the introduction of China’s original high-speed wire EDM wire cutting has been more mature as the processing technology widely used in the production of the actual. How to improve the high-speed wire-cutting machine tool to meet the processing accuracy of special parts and molding requirements, more and more domestic counterparts attach importance. In recent years, through the study of high speed wire cutting process, it has been generally recognized that in addition to the machine tool, the accuracy of the controller, the pulse power and the performance of the working fluid, the electrode wire vibration state
