| Abstract: | During the machining process of small hole EDM drilling,there are many serious questions,such as the serious tool electrode loss,the slow machining speed,the corner wear resulting taper shape.Analyzing the cause of these questions,the paper sugests adopting Cu-Cr composite electrode for small hole EDM drilling.Processing mechanism is analyzed and an experiment is carried out.Experimental results indicate that comparing with Cu electrode,Cu-Cr composite electrode can remarkably improve the processing speed a... |
