摘　　要：在BDM-903精密数控电火花超硬刀具磨床上,通过正交试验获得了2组聚晶金刚石复合片的精加工条件。在此基础上,研究了脉冲控制参数、辅助电源参数、电极转速对精加工效率的影响,得出了最佳高压辅助回路追加电流以及最佳电极转速,分析了辅助电源参数对PDC表面粗糙度的影响以及伺服进给速度参数与辅助电源参数对PDC粗加工效率的影响,并得出最高粗加工效率下电极的最佳伺服进给速度。Two sets of EDM conditions were obtained through the orthogonal test on the BDM-903 precise CNC EDM machine. On this basis, the influence of the pulse control, assistant power supply and the electrode rotation speed on the ac curate EDM efficiency were studied, thus the additional electric current of high voltage auxiliary circuit and the optimum e lec＊rode rotation speed were gained by the results of experimental data analysis. The effects of the high voltage auxiliary cir- cuit on the surface roughness of PDC were investigated, and the effects of servo control speed of the electrode as well as the high voltage auxiliary circuit on the rough working efficiency of PDC were evaluated and analyzed, and then the best elec trode rotation speed on the rough EDM conditions was obtained.
