研究了利用超声波提高气体介质中电火花加工效率的方法。这种新方法被称为超声辅助电火花加工(UEDM)。在气体电火花加工过程中,工具电极是一个薄壁管道,高压气体介质从内部施加,超声波驱动作用于工件。在我们的实验中,工件材料为AISI 1045钢,电极材料为铜。实验结果表明:(a)材料去除率(MRR)随开路电压、脉冲持续时间、超声驱动幅值、放电电流和电极管壁厚的减小而增大;(b)表面粗糙度随开路电压、脉冲持续时间和放电电流的增加而增加。在实验结果的基础上,建立了估计磁阻比和表面粗糙度的理论模型。
This study focuses on using ultrasonic to improve the efficiency in electrical discharge machining (EDM) in gas medium. The new method is referred to as ultrasonic-assisted electrical discharge machining (UEDM). In the process of UEDM in gas, the tool electrode is a thin-walled pipe, the high-pressure gas medium is applied from inside, and the ultrasonic actuation is applied onto the workpiece. In our experiment, the workpiece material is AISI 1045 steel and the electrode material is copper. The experiment results indicate that (a) the Material Removal Rate (MRR) is increased with respect to the increase of the open voltage, the pulse duration, the amplitude of ultrasonic actuation, the discharge current, and the decrease of the wall thickness of electrode pipe; and (b) the surface roughness is increased with respect to the increase of the open voltage, the pulse duration, and the discharge current. Based on experimental results, a theoretical model to estimate the MRR and the surface roughness is developed.
