中文摘要：

利用超声振动、电火花脉冲放电的加工特点,将其同单一普通磨削优化组合,可以得到较好的加工效果。从加工表面粗糙度、表面微观形貌两个方面,比较了单一磨削、超声振动辅助磨削、磨削—电火花脉冲放电复合加工、超声振动辅助磨削—电火花脉冲放电复合加工的加工效果,得出了不同加工方法的优缺点。通过对几种加工方法的优化组合,设计了新的加工工艺。实验结果证明,新的加工工艺可以有效地提高加工表面质量,减少裂纹和热应力的产生。

英文摘要：

The optimal combination of grinding, electrical discharge machining（EDM）, and ultrasonic vibration,based on their advantages, can receive better machining surface. Machining performance of traditional grinding, ultrasonic vibration aided grinding, EDM-- grinding, and ultrasonic vibration aided grinding--EDM was compared from surface roughness and microcosmic surface pattern through experimental data. A new machining process was designed by optimizing the four machining styles. The experimental data show that the new machining process can improve the surface quality and decrease the appearance of grinding crack and thermal stress.
