Abstract Electric Discharge Milling Machining (EDMM) simplifies the electrode manufacturing process and reduces the cost. However, the introducing of new parameters, such as the three-dimensional motion and the electrode rotation speed, results in a periodic change of control state that can reduce the control performance and processing efficiency. In this work, ultrasonic vibration of tool electrode was used to improve the processing efficiency of ceramic materials. The effect of ultrasonic vibration on the EDMM process was analyzed by comparing the experimental findings. The results have shown that the ultrasonic vibration can improve the material removal rate, and a treble processing efficiency was achieved. The effect of processing parameters on the material removal rate, such as the open voltage, the peak current, the pulse during time and the pulse off time, was analyzed. When aided with the ultrasonic vibration, the best processing efficiency was achieved at 220 V for the open voltage, 10 A for the peak current and 15 μs for both the pulse during time and pulse off time.

以去离子水为加工介质超声振动辅助放电铣削陶瓷材料的MRR实验研究

摘要 放电铣削加工（EDMM）简化了电极制造工艺，降低了成本。然而，引入新的参数，如三维运动和电极旋转速度，会导致控制状态的周期性变化，从而降低控制性能和处理效率。在这项工作中，工具电极的超声振动被用来提高陶瓷材料的加工效率。通过比较实验结果，分析了超声波振动对EDMM工艺的影响。结果表明，超声振动可以提高材料去除率，达到三倍的加工效率。加工参数对材料去除率的影响，如开路电压、峰值电流、分析了脉冲期间和脉冲关闭时间。在超声波振动的辅助下，开路电压为 220 V，峰值电流为 10 A，脉冲持续时间和脉冲关闭时间均为 15 μs，处理效率最高。
