Research of PZT Excited Discharge Channel Compression Micro-EDM Techniques
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 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.In this paper,the system composition and machining principles are described in detail,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,which indicated that this new technology has wide application prospect in the field of micro manufacturing.
