Abstract: In the present study or Experiment, pure aluminum alloy powder is mixed with 12% Silicon Carbide on weight basis to produce the MMC (metal matrix composite) material. The main objective of this paper and study is to investigate the effect of process parameters such as pulse on time(Ton), flushing pressure (Fp) and peak current (Ip) on tool wear rate (TWR), metal removing rate (MRR) and surface roughness (SR) during electrical discharge machining (EDM) of Al-SiC12% MMC .The experiment is done by Central composite design (CCD) method under different combination of process parameters .In this Experiment or paper RSM (Response surface methodology) is used to develop the mathematical model and to correlate the process parameters with the response. Also ANOVA (Analysis of Variance) technique is used to check the significance of the model and confirmation test is done to compare the predicted data with the Experimental data to identify the effectiveness of the given method. From the main effective plot or graph it is found that peak current is the most significant process parameter among the other parameter. Further the morphology study of the composite material is carried out by the FESEM (Field emission Scanning electron microscope) of the surface after machining to make a relation with the model.
