Based on inverse piezoelectric effect, a new micro-EDM method called piezoelectric self-adaptive micro-EDM was proposed in this paper. The tool structure and working principle of this new method is simple and it is different from the conventional micro-EDM system. A piezoelectric actuator with high resolution and high response frequency was employed as the micro driven mechanism in this system. Because...
Micro electrical discharge machining (micro-EDM) has some shortcomings such as poor material removal rate and high electrode wear ratio etc. In order to overcome these demerits, a new piezoelectric self-adaptive micro-EDM, based on inverse piezoelectric effect, was developed in this paper. Piezoelectric actuator is used as the micro driving part. The working mechanism of this new technology is different...
