In several research studies, many experiments have been conducted on non-traditional Electric Discharge Machining (EDM) and also investigated how different EDM process parameters influence the surface quality and productivity. EDM is a material removal process in which desired shape can be obtained by generation of spark. EDM process parameters play the vital role to improve the surface finish and productivity simultaneously. This paper presents the effects of EDM machining parameter such as Discharge ON Time, Discharge OFF Time, and Wire Feed, and their interactions on the Material Removal Rate (MRR) and Surface Roughness (SR) during the machining of magnesium matrix composites (MgZE41A) reinforced with Ag and LiAlO2. The hybrid composite of 97Mg+1.5Ag+1.5 LiAlO2 combination is selected for manufacture using powder metallurgy technique as it has a high wear resistance. Analysis of Variance (ANOVA) is adopted to study the influencing process parameters for each response. Desirability function analysis (DFA) tool is adopted to find the optimal EDM process parameters which would reduce the surface roughness and improve the material removal rate simultaneously. From the analysis results it has been found that desirability ‘D’ of 0.55 gives the better results.
Keywords: ANOVA, Desirability, EDM, Surface roughness and MgZE41.
