提出了一种新型的微细电火花加工方法--压电自适应微细电火花加工。介绍了基于逆压电效应的压电自适应微细电火花加工的工作机理。与传统的微细电火花加工方法不同，这种加工方法可以根据放电条件实现自调节。论述了压电自适应微细电火花加工的一些特点，如有利于去除加工中的碎屑、减少电弧/短路的发生、实现短路的自消除等。与常规微细电火花加工相比，该加工方法大大提高了加工过程的放电稳定性，提高了加工效率，降低了电极损耗率。设计了一种实现压电陶瓷微细电火花加工的专用机床，并利用VisualC ++2010开发了该机床的数控软件。做了大量的实验。实验结果表明，压电自适应微细电火花加工是一种加工微小孔、微小槽及某些微小结构零件的有效方法。
A new kind of micro electrical discharge machining (EDM), piezoelectric self-adaptive micro electrical discharge machining, is proposed in this paper. The working mechanism of piezoelectric self-adaptive micro-EDM, which is based on inverse piezoelectric effect, is introduced. The new machining method, being different from the conventional micro-EDM, can realize self-regulation depending on discharge conditions. Some characteristics of piezoelectric self-adaptive micro-EDM, such as being benefited for removing the debris, reducing the occurrence of arcing/shorting circuits and realizing the self-elimination of short circuits, is talked about. Comparing with conventional micro-EDM, the discharge stability of the working process is improved greatly, and the machining efficiency is higher and the electrode wear ration is lower. A special micro-EDM machine is designed to realize mechanism of piezoelectric micro-EDM, the CNC software is developed with Visual C++2010 for the machine. Extensive experiments were done. The experimental results show that piezoelectric self-adaptive micro-EDM is an effective machining method for micro holes, micro slots and some micro structural parts.
