In the present study, the mathematical model was developed to investigate the effects of current, pulse on time and pulse off time in EDM performance on surface roughness during machining of AA6061 wt.15% B4Cp metal matrix composite. The aluminum composite is prepared by taking weight. 85% of AA6061 and weight. 15% of B4Cp through stir casting technique. In order to analyze the machinability of aluminum composite, the experimental design was planned as per Box-Behnken design (BBD). The modeling and optimization of electric discharge machining has been done using Design Expert software 7.0. The validity test of the fit and adequacy of the proposed model for surface roughness has been carried out through analysis of variance (ANOVA). The percentage error between the predicted values and the experimental values of response factors obtained through confirmation experiments are within 5%. From the analysis, it is evident that current and pulse on time was found to have significant effect on surface roughness.Keywords

Nowadays modern manufacturing system is enforced to find out the new material such as metal matrix composite or ceramic matrix composite. The aim of this research is to invent the aluminium based metal matrix composite such as 80% of Al 6061-20% of SiC and 90% of Al 6061-10% of SiC. The aluminum 6061 alloy based composite is prepared through stir casting route. Then the composite is heat treated at the critical temperature. After heat treatment, the mechanical properties of composite are compared before extrusion and after heat treatment. Mechanical properties of both heat-treated and as fabricated composites showed a high dependence on the ceramic content. The yield, ultimate tensile strength, and the elastic modulus of the material were increased with volume fraction of carbide, whereas the ductility was decreased. The tensile properties are seen to vary significantly with ageing treatment. The highest strengths were obtained for the solution heat-treated and naturally aged Al-6061: SiC composites containing 20 vol. % SiC.Keywords
