一、前言 近几年来随着晶体管脉冲电源的出现。电火花加工的生产率大为提高。电极耗损减小到几乎可以忽略的程度。大型模具和大型工件的加工也已成为可能。应用领域不断扩大。为了获得和选择最好的加工条件。加工工艺过程中涉及的因素也相应地增加了。
I. Introduction In recent years, with the emergence of transistor pulse power. EDM productivity greatly improved. Electrode wear reduced to almost negligible extent. Large-scale molds and large parts of the processing has also become possible. Applications continue to expand. In order to obtain and choose the best processing conditions. The factors involved in the process are also correspondingly increased.
