为解决传统电火花加工工艺对环境的污染和加工效率低的问题，提出了一种水基电火花高速铣削加工的可持续制造方法。首先，研究了运动电弧的加工原理。建立了运动电弧高速电火花铣削加工的数学模型，并利用数学模型对运动电弧高速电火花铣削加工的特性进行了分析。对钛合金进行了加工试验，分析了该方法的加工特性。实验结果表明，材料去除率（MRR）显着提高。最大MRR几乎是传统EDM的五倍。高速电火花铣削加工中，刀具电极的磨损较低，这主要是由于刀具电极的高速旋转以及Ti-6A 1 -4V的溅射和沉积在刀具电极表面形成了保护层。(C)2018爱思唯尔有限公司版权所有
In order to solve the environmental pollution and low machining efficiency of conventional EDM process, a sustainable manufacturing method of high-speed EDM milling while using water-based dielectric is proposed. Firstly, the machining principle of moving electric arcs was investigated. Then, models were established and utilized to explain the characteristics of high-speed EDM milling with moving electric arcs. Experiments on machining titanium alloy with this method were carried out to analyze the machining characteristics. The experimental results showed that the material removal rate (MRR) was significantly improved. The maximum MRR was almost five times greater than that of conventional EDM. Moreover, the lower tool-electrode wear in high-speed EDM milling was obtained, which can be attributed to the high-speed rotation of tool-electrode and protective layer formation on the tool electrode surface caused by sputtering and deposition of Ti-6A1-4V.
