摘要：

In micro-EDM, the debris generated in machining process is difficult to be moved from the discharging gap, the discharge state is instability, and the material removal rate is low. A new method of piezoelectric ceramic (PZT) incentive synchronous compression discharge channel micro-EDM is presented based on the inverse piezoelectric effect of PZT piezoelectric ceramics, using a spark discharge and PZT sync pulse power. The system composition and machining principles are described, and its machining mechanism is analyzed in terms of the experiments. By the experiments, it is certificated that on the process of PZT sync compressing discharge channel machining, the state of discharge gap, the machining efficiency and quality can be improved, the throw out of debris makes easier, and then the stability of micro-EDM process is raised. A micro-hold is produced diameter in 67 μm with stable machining process by using a self-developed machining system, which indicates that this new technology has wide application prospect in the field of micro manufacturing. © 2013 Journal of Mechanical Engineering.
