摘要
The aim of this study is to investigate the machining characteristics of gas media used in electrical discharge machining (EDM). The process parameters were designed based on Taguchi method to manage the experimental work. The main process parameters such as machining polarity, gas pressure, peak current, pulse duration, type of gas media, and servo reference voltage were adopted to explore their effects on machining performance in terms of material removal rate (MRR) and surface roughness (SR) for SKD 61 tool steel. The experimental observed values were transferred to signal-to-noise (S/N) ratios, and then the significant machining parameters affecting obviously the machining performance were determined by analysis of variance (ANOVA). The optimal combination level of machining parameter for each machining characteristic was obtained by the S/N ratio analysis according to Taguchi methodology.
