Abstract: EDM is an important means of processing in mould processing industry. In this paper, the Su-Field analysis method is applied to study the mechanism of EDM, the application process of Su-Field analysis method to solve the problem of EDM discharge system was established, the microscopic process of EDM dielectric breakdown was described, the Su-Field model of the single pulse discharge four phases, discharge channel formation, breakdown discharge, galvanic corrosion throwing and the deionisation between the medium, was established, and finally the complete Su-Field model of single pulse discharge process of EDM was achieved. In the single-pulse discharge established Su-Field model basis, the factors affecting the processing speed, surface roughness and electrode wear were analysed, further integration of 76 standard solutions, the plan to solve the problem of instability in the discharge process was achieved, at the same time, a new way for the research of EDM process was provided.
