Abstract
In this present investigation aluminium composite reinforced with fly ash fabricated by stir casting process. The objective of the research work is to optimize the Wire EDM process parameters such as input current, pulse on time, pulse off time, wire feed for the surface roughness and material removal rate of aluminium matrix composites (AMCs).The experimental work has been carried out by using Taguchi L9 orthogonal array under appropriate combination of process parameter. Analysis of variance (ANOVA) used to find out the design parameter how significantly influencing the responses. To evaluate the influence of these parameter Signal to Noise(S/N) ratio analysis has been done. The result shows the optimum combination of parameter which give the maximum metal removal rate and minimum surface roughness.
