In now days Aluminium Metal Matrix Composite (AMMC) has become one of the most favorite material for automotive, aerospace, shipyard etc. industry because of their outstanding properties such as high wear and corrosive resistance, remarkable hardness and toughness, low density, light weight etc. But because of the complexity of the cutting geometry and mechanical properties of work materials the use of convectional machining process becomes limited. Such difficulties are easily sort-out by using electric discharge non convectional machining process (EDM) because in this case material removal takes place by thermal erosion process. The present research work highlight the effect of process parameter on output response during the EDM of Aluminium7075- Boron carbide-Graphite (Al/B4C/Gr) metal matrix composite (MMC). Taguchi technique is used for design of experiments. Fitness and adequacy of the experimentation has tested through the analysis of variance (ANOVA).
