在电火花加工中，加工特性在很大程度上取决于能量分布。因此，弄清能量分布对于理解电火花加工中的各种现象是非常重要的。本文通过测量电极和工件的温度，研究了石墨电极电火花加工过程中的能量分布。实验分析表明，材料去除率取决于能量密度，电极磨损主要取决于加工液中热分解碳的粘附，且分布到电极和工件中的能量几乎不变，与脉冲宽度无关。
In EDM, the machining characteristics greatly depend on the energy distribution. Therefore, it is very important to clarify the energy distribution for understanding various phenomena in EDM. In this paper, the energy distribution in EDM with graphite electrode is investigated by measuring the temperatures of electrode and workpiece. Experimental analysis shows that the material removal rate depends on energy density while the electrode wear greatly depends on the adhesion of heat resolved carbon from machining fluid, and the energies distributed into electrode and workpiece are almost constant regardless of pulse duration.
