摘要：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 from traditional micro-EDM. This new technology can realize self-elimination of short circuits in the working process because of its special structure. Working mechanism and process of the new system were illustrated. An empirical mathematical model on single-pulse discharge crater diameter against the key machining parameters was developed through partial least squares (PLS) regression to quantitatively disclose the discharge mechanism of this new technology. The effects of parameters such as voltage, capacitance, and resistance on MRR were analyzed. The empirical model represents good fits with the experimental data. (C) 2010 Published by Elsevier Ltd.
