摘要

Electrical Discharge Machining is a non-contact machining process for shaping and forming deep and complex-shaped holes for all kinds of electro-conductive materials regardless of their hardness. Recently, a demand in micro machining has extended into biomedical application for lubrication of artificial human joint. A micro pits formation is therefore proposed for lubrication purpose, which eventually prolong the lifespan of the hip implant. In this case, particular size of crater in micro will be developed in various positions and depth on the artificial joint surface to ease friction between metal joint. Therefore, this paper proposes a new design of Pulse Power Generator by considering the optimum material removal rate, the relative wear ratio, the surface crack density and the surface finish quality of the workpiece produced.
