Abstract
With the development of modern science and technology, the application of electrical discharge machining (EDM) has becomes more and more widespread. In this paper, GAMBIT software was used to establish the three-dimensional model of the deep hole machining process. On the basis of theoretical analysis of the gap of flow field working liquid, FLUENT software was used to simulate the bubble motion process for the multiple pulse discharge process. In addition, ultrasonic was imported into the EDM process, the bubble motion process was simulated and compared with the conditional process. The result presented was that the ultrasonic assisted machining process produced more bubbles, and the machining efficiency was improved.
