电火花线切割加工工艺研究

Research on the WEDM Technology

电火花线切割加工的用途已越来越广泛,主要介绍了其加工原理;薄工件的加工方法;减少和防止工件的变形和开裂的措施;加工表面的黑白条纹产生的原因,同时还提出了限制黑白条纹的对策。本文能针对这些常见加工工艺问题,结合自己的实践提出一些解决办法,以期给使用电火花线切割加工者带来一些参考办法和经验。

The usage of WEDM is more and more widely. This thesis mainly introduces the principles of its processing, the processing method of thin and small workpiece, the measures to reduce and prevent the cracking and deformation of workpiece, the cause of black and-white-stripes on the surface, Furthermore, the strategy for restriction the black-andwhite-stripes is put forward. We often encounter these technology problems, so this thesis gives some solution to these problems according to our own practice. The solution and experience is useful for the WEDM processor, and this thesis is my modest contribution to the promotion of WEDM Technology.
