Abstract
In this paper, the work energy on the machined surface during electrical discharge machining (short in EDM) process were modeling analyzed based on the electron field emission theory, electron sputtering theory and the effect of resistance heat of electron current when the tool electrode is positive. A series of single-hole EDM experiments and the metallographic examinations were designed. The study shows that the concentration ratio of the work energy on the machined surface increase with the increase of the equivalent radius ratio of real discharging area and the area of workpiece end surface and the reduction of the interelectrode discharging current. While it can be obtained that the ratio of the resistance heat to the total work energy increase with the decrease of the equivalent radius ratio of real discharging area and the area of workpiece end surface and the increase of the interelectrode discharging current.
