Powder Mixed near Dry Electrical Discharge Machining

Abstract:

Powder mixed near dry electrical discharge machining (PMND-EDM), which uses gas-liquid-powder mixture as three phase dielectric medium to remove materials, is proposed. Compared with dry EDM, much higher material removal rate (MRR) is achieved in PMND-EDM. The mechanism of PMND-EDM is analyzed and reasons for its MRR improvement are illustrated. Comparative experiment is done in compressed air and three phase dielectric medium, respectively. MRR is calculated. And discharge voltage waveforms are obtained by oscilloscope. It is shown that three phase dielectric medium can improve MRR effectively.
