Notes:
In order to operate in narrow space, a novel miniaturized EDM (Electro DischargeMachining) mechanism has been developed. A prototype of miniaturized EDM device based onultrasonic motor (UM) has been developed, which has its advantage of compact size (70×40×50 mm).The differential driving electrode has been presented, and coaxial forced vibration of electrode isbenefit for the evacuation of debris, so it helps to achieve stable and efficient machining. Drivingprinciple of ultrasonic motor is analyzed, and simulation using Finite Element Method (FEM) isaccomplished. The auto-frequency tracking has been carried out, in order that the motor work onresonant or quasi-resonant frequency. Finally, EDM experiment has been finished, and holes withfigures of circleΦ85μm and Y-typed have been machined
