摘要

Multi-objective optimization in the machining process is a very important issue, and it contributes to improving productivity and quality in practice. Therefore, research results on this issue are very necessary. This work used WC electrodes to achieve a multi-objective optimization of technical parameters in micro-EDM. Ti-6Al-4V titanium alloy was utilized to make the ingot. Current (I), voltage (Vg), and pulse on time (Ton) were employed as adjustment parameters. The Z and OVC targets in micro-EDM with WC electrode were chosen concurrently using the Taguchi technique and Deng's approach. The results showed that the optimal technological parameters are V = 160 V, C = 10 nF and RPM = 400 rpm. The optimization result by the ranking method of C* is better than that of the S/N analysis of C*. V = 160 V could produce better machinability with C = 10 snF and RPM = 200 rpm. A reduced agglomeration of tool electrodes was found across the machined titanium specimen, indicating that the ideal process settings can yield a superior machined surface quality. If WC electrode is used instead of machined titanium specimens, less microcracks and voids may result. Surface quality indicators machined after micro-EDM with WC electrodes need to continue to be considered, including surface layer structure, physical characteristics of the surface layer, size and pore structure, etc.
