| Abstract: | Based on the researches of the physical characteristics of Polycrystalline Diamond(PCD) and the electric discharge mechanism, some important factors which influence the material removal rate and surface quality when machining large diameter PCD was found out. An ideal power supply model, which has advantages such as high energy, high peak voltage, high peak current, small pulse width and equal output of pulse energy for machining large diameter PCD was put forward. According to this model, a high efficiency, energy saving and environment protecting pulse power supply was developed. Compared to the generally used ones, this new power has such advantages as high processing efficiency, guaranteeing better machined surface and high utilization of electrical energy. So this new power is an effective tool for machining large diameter PCD by electric discharge grinding process. |
