The μ-EDM machining efficiency of PCD was investigated with different electrode material and discharge circuits. The experimental results show that micro-grooves on PCD are formed rapidly by μ-EDM scanning with tungsten electrode and resistance capacitance (RC) discharge circuit. Moreover, combined with wire electro-discharge grinding (WEDG), micro sphere cavities and complex cavities on PCD are successfully machined by μ-EDM scanning process. The surface roughness of cavities on PCD is as small as Ra 0.2μm and the surface roughness of cavities on WC is as small as Ra 0.122μm by means of μ-EDM scanning process. 許東亞 2009 學位論文 ; thesis 65 zh-TW
