Ezperiment Research of the Electrical Discharge Machining Parameters Effected on Microstructure of Polycrystalline Diamond

摘要：

The samples of polycrystalline diamond (PCD) were machined by adjusting the main parameters of electrical discharge machining. After the machining, the phases were analyzed by X-ray diffraction analyzer and the surface layer microstructure were observed by scanning electronic microscope. The fundamental component of machined PCD affected layer was obtained and the reason of bring affected layer was analyzed. The relationship curves between pulse width or working electric current and depth affected layer or the ratio of surface roughness were summarized. These researches provide valuable test reference for drawing up technics of PCD discharge machining.
