Abstract

The intent of present study is to study the effect of process parameters on Surface Roughness , Material Removal Rate and Tool Wear Rate in electric discharge machining of aluminum alloy (Al+SIC+Mg) metal matrix composites. The design of experiments approach using Taguchi method is used to optimize the parameters like Peak Current, Tool Material and Pulse-On Time in EDM of Al Metal Matrix composites for minimum Surface Roughness and Tool Wear Rate, and maximum Material Removal Rate. T-3822M electric discharge machine is used to machine the Metal Matrix Composite. Experiments are conducted based on the Taguchi parameter design by varying the Peak Current, Pulse On-Time and Tool Material. Signal-to-noise ratio and analysis of variance are used to study the effect of parameters on the Surface Roughness, Material Removal Rate and Tool Wear Rate.
