JFET_V7_N3_RP1 N. Muthukrishnan Journal on Future Engineering and Technology 2230 – 7184 7 3 17 25 ANOVA, Cutting Mechanism, Desirability Analysis, Metal Matrix Composite, Multiple Responses, Optimization Aluminum matrix composite is the innovation of high performance material technology and it has superior interfacial integrity and thermodynamic stability between the matrix and reinforcement. Making the engineering components from this composite material require machining operations. Therefore, addressing the mach inability issues of the composite is very important. This paper proposes an approach to optimize the machining parameters in turning of Al 6061-10% ZrB2 Metal Matrix Composite (MMC) with performance characteristics by using desirability analysis. The effect of ZrB2 reinforcement particles on machinability behavior need to be studied. The machining parameters, namely cutting speed, feed rate and depth of cut are optimized with considerations of multiple performance characteristics including surface roughness and power consumed. It is concluded that the feed rate has the strongest effect. The confir­mation experiment indicates that there is a good agreement between the estimated value and experimental Value of the desirability function grade.
