| Abstract: | A new machining method named vibration aided submersed gas-jetting EDM was proposed in this paper.In this method,workpiece vibration was adopted to improve the discharge status and reduce the probability of short circuit.Experiments were conducted to study the effects of vibration frequency and amplitude on the machining performance of this method.The effects of discharge parameters,gas pressure,and rotation speed of the tool electrode was also studied.The results indicate that workpiece vibration can effectively improve the material removal rate(MRR) and the workpiece surface quality without increasing the tool electrode wear. |
