Abstract: In order to resolve the problem of long assistant machining time,miniaturized EDM device with electrode direct driving mechanism has been designed,using an ultrasonic motor as its driver.The analysis of vibration modal is accomplished by using ANSYS.Further more,the optimal vibration modal and driving frequency have been implemented by animate function of ANSYS.The test of the whole system has been conducted,and the feasibility of the system has been verified.
