Metal based aluminum matrix composites now show a crucial part in today’s industry. Aluminum based is used in automobile industries to maximizing the millage by reducing the weight of automobiles. In this investigation, the hybrid aluminum based metal matrix composite is developed by selected by aluminum, copper and nickel as matrix material and boron nitride as reinforcement materials. The abrasive water jet machining is employed to make the hole in developed composite by considering the rate of feed, distance stand of nozzle from material and stream rate of water with abrasive as input machining parameters and material removal rate as output parameters. Taguchi approach based L9 array method is employed to find nine set of machining parameters and optimizing for maximizing material removal rate. Analysis of variance table is employed to check the consequenceof input machining parameters and the surface plot, contour graphis adopted to identify the influence of input machiningvariables on the output. The optimized machining parameters are rate of feed is 20mm/min, distance of stand by nozzle 3mm and the flow rate of abrasive water with 400 gm/min for maximizing the material removal rate.
