Ultrasonic vibration electrical discharge machining (UEDM) in gas is proposed in this paper.
本文主题是关于气体保护超声波振动电火花加工( uedm )。
It is shown that electrical discharge machining with ultrasonic aid can be achieved well in gas medium
.The tool electrode is formed to be thin-walled pipe, and high pressure gas medium is supplied through it. 工具电极呈是薄壁管状，内部接通高压保护气体介质。.
During machining, ultrasonic vibration of workpiece can improve the machining process.
The molten workpiece material can be ejected out from base body of workpiece with the aid of ultrasonic vibration and be removed/flushed out of the working gap without being reattached to the electrode.
A theoretical model to estimate the material removal rate has been developed.
Selecting 45# steel and copper as the workpiece material and electrode material, respectively, experiments have been carried out, the results showing that UEDM is a method with a high material removal rate (MRR).
分别采用选拔45#钢作为工件材料，铜作为电极材料进行实验，结果显示uedm是一种具有高材料切除率( MRR) 的加工方法.
The greatest advantages of this technique are lower pollution and low electrode wear ratio.
