传统的电火花铣削加工方法在加工难加工材料时存在加工效率低、能耗高、电极磨损严重、加工环境差等缺点。本文针对上述问题，提出了一种可持续、高效的电火花铣削加工方法。设计了一种高能量、高效率的绿色脉冲电源，并采用不同的环保工质进行了加工实验。研究了该方法的能量利用率、环境性能和不同条件下的加工性能。结果表明，该方法具有加工效率高、能耗低、电极磨损小、环境友好等特点。加工17- 4PH不锈钢工件时，材料去除率可达900.66mm3/min，电极相对磨损率为1.20%。实验结果表明，新型脉冲电源的能量利用率提高了200%以上。与传统的电火花铣削加工方法相比，该方法能够满足节能和可持续生产的要求。(C)2020爱思唯尔有限公司保留所有权利。
Conventional electrical discharge machining (EDM) milling methods have some disadvantages when used to machine difficult-to-cut materials, including low machining efficiency, high energy consumption, severe electrode wear, and poor processing environments. In this paper, a sustainable and high-efficiency EDM milling method is proposed for solving the above problems. A high-efficiency green pulse power supply with high energy is designed and different environmentally friendly working fluids are used for machining experiments. The energy utilization rate, environmental performance, and machining per-formance under different conditions of this new method are studied. The results show that the proposed method presents high machining efficiency, low energy consumption, mild electrode wear, and environmentally friendly features. The material removal rate can reach 900.66 mm(3)/min and the relative electrode wear rate is 1.20% when machining the 17-4 PH stainless steel workpiece. It is found that the new pulse power supply increases the energy utilization rate by more than 200%. Compared with the conventional EDM milling methods, the proposed method can meet the requirements of energy-saving and sustainable production. (C) 2020 Elsevier Ltd. All rights reserved.
