摘要
提出了一种超高效电火花电弧复合铣削镍基高温合金Inconel 718的加工方法,构建了一种新型大功率电源,主要由高压脉冲电源和低压大功率直流电源组成。在冲液和电极旋转的作用下得到了非连续电弧,材料去除率可达13 421 mm3/min,相对电极损耗率可达1.71%。进行了复合加工和电火花加工的对比实验研究,分析了电极转速对材料去除率和相对电极损耗率的影响,并对加工表面特性进行了研究。
This paper proposed a high efficient combined machining of electrical discharge machining and arc machining for machining Inconel 718. The proposed power supply comprised a pulse generator with high voltage and a DC power source with high current. Benefiting from efficient flushing and electrode rotation,the noncontinuous arc was yielded,and the maximum material removal rate （MRR） achieved 13 421 mm3/min with a relative electrode wear ratio （REWR） of 1.71%. Comparison experiments were conducted to reveal the differences between EDM and compound machining. And the effects of rotation speed on MRR and REWR were investigated. Surface integrity was also studied.
