提出了一种钛合金（Ti6 Al 4V）的超高速电火花铣削复合加工方法。电源由脉冲发生器和直流电源组成，两者相互隔离。将旋转管石墨电极连接到电源的负极。等离子体通道能够去毛刺，最大材料去除率（MRR）达到21,494 mm 3/min，相对电极磨损率（REWR）为1.7%，因为高电流和有效的冲洗。与传统的电火花加工相比，复合加工获得了明显更高的MRR，但相似的REWR。研究了电极极性、峰值电压、峰值电流和冲洗压力对复合加工性能的影响，包括MRR、REWR和过切半径（ROC）。此外，扫描电子显微镜，X射线衍射和显微硬度分析进行。结果表明，该方法可以有效地加工难加工材料。
A novel compound machining of titanium alloy (Ti6Al4V) by super high speed electrical discharge machining (EDM) milling and arc machining was proposed in this paper. The power supply consisted of a pulse generator and a DC power source which were isolated from each other. A rotating pipe graphite electrode was connected to the negative pole of the power supply. The plasma channel was able to deionize, and maximum material removal rate (MRR) reached 21,494 mm3/min with a relative electrode wear ratio (REWR) of 1.7% because of high current and efficient flushing. Compared with traditional EDM, the compound machining achieved a significantly higher MRR but a similar REWR. To investigate the characteristics of the compound machining, the effects of electrode polarity, peak voltage, peak current, and flushing pressure on the performance of the process, including its MRR, REWR, and radius of overcut (ROC), were determined. In addition, scanning electron microscopy, X-ray diffraction, and microhardness analysis were conducted. Result shows that the proposed method can machine difficult-to-machine materials efficiently.
