Abstract

Research on optimization of technological parameters in micro-EDM is very important, and especially results in multi-objective optimization problem. It led to improve machining performance like machining accuracy, reduced electrode wear and improved surface quality. Recent studies mainly refer to the quality indicators of machining productivity and electrode wear, besides that machining accuracy and surface quality are also very important indicators but published results about them is very limited. In this study, Z Co-Ordinate (Z) and overcut (OC) in micro-EDM using tungsten carbide (WC) electrode for Ti-6Al-4V were decided simultaneously by TOPSIS. Technological parameters which include Voltage (V), Capacitance (C) and Response surface methodology (RPM) were investigated in the presented research work. The results showed that the quality parameters Z and OC at optimal conditions were significantly improved.The surface quality behind the microEDM is also analyzed and evaluated, and it is good.

用碳化钨电极加工钛合金微电火花加工Z轴协调器和过切的多目标决策

微细电火花加工工艺参数的优化研究是一个非常重要的问题，尤其是多目标优化问题。提高了加工精度，减少了电极磨损，改善了表面质量。目前研究的质量指标主要是加工生产率和电极磨损，加工精度和表面质量也是非常重要的指标，但发表的成果非常有限。本研究采用TOPSIS法同时确定了Ti-6Al-4V用碳化钨(WC)电极微细电火花加工的Z坐标(Z)和过切(OC)。研究了包括电压(V)、电容(C)和响应面法(RPM)在内的工艺参数。结果表明，在最优条件下，质量参数Z和OC均有显著提高。对微细电火花加工后的表面质量进行了分析和评价，结果表明微细电火花加工后的表面质量良好。
