摘要：

This paper studied the phenomenon of electrode resistance formed on the electrode surface in EDM(Electrical Discharge Machining). Firstly, the heat conduction process in EDM was analyzed using thermal conduction theory, the expressions of temperature distribution for the heat conduction process under the time-varying radius and fixed input total power was obtained. And then, whether electrode resist can be formed or not under different processing condition was qualitatively analyzed according to electrode surface temperature distribution and electrode resist forming conditions. The relations between electrode resistance and electrode wear, and the main influencing factors including peak current, pulse duration, pulse interval and machining time were studied by orthogonal experiment.
