| Abstract: | A new type of method, in which direct driving of electrode tool is applied using piezoelectric driving technology, appears in the middle of 1990's. Such technology could be applied to machine micro-devices and profiled micro-holes in the fields of aerospace and aeronautics, precision mould, medical instruments etc..In this paper, several representative piezoelectric driving methods are reviewed, such as elliptical-type EDM, ultrasonic-motor-based EDM, inchworm-type EDM. At the same time, in order to increase efficiency and to decrease machining time, possibility and characteristics of ultrasonic enhanced micro EDM are put forward as a reference to a further development of piezoelectric driving EDM. |
