| Abstract: | Based on the field emission theory,a plate-capacitor model is constructed to describe the electrical discharging machining(EDM) process.In this model,the discharging pulse period is divided into four stages,successively as the establishment of the interelectrode electrical field,the formation of the interelectrode discharging channel,the stable EDM and deionization,and the correlative parameters of each stages,such as the intensity of interelectrode electric field,the mean free path of interelectrode electr... |
