In present the increased demand of lightweight materials with high strength to weight ratio in the aerospace and automotive industries has led to the development and use of Al-alloy-based composites. In this paper an attempt has been made to prepare Al6082+Cu+Zn composite material and the optimization of CNC milling process parameters for three different work materials of compositions are Al6082 96%+Cu3%+Zn1%, Al6082 92%+Cu5%+Zn3% and Al6082 89%+Cu7%+Zn4%composite material. .¬¬The characteristics of these alloys have strength as well as weight ratio makes the extensive research on Al-Cu-Zn alloy Metal matrix composite (MMC) is carried out universally because of it is widely used in automotive & aerospace industries. Tribological behavior of aluminum alloy matrix is fabricated by using the stir casting process was investigated. The theory of grey systems is a new optimizing technique for performing the prediction, grey relational analysis and decision making in many areas. In this paper, the use of grey relational analysis for to optimizing the machining process parameters for the work piece is surface roughness and the metal removal rate is introduced. In order to improve the quality and productivity the present study highlights the optimization of CNC milling process parameters like speed, feed rate, depth of cut and different coated HSS tools to provide a good surface finish as well as high material removal rate. Hence a multi objective optimization problem has been obtained which can be solved by the hybrid Taguchi method comprising of grey relational analysis.. Finally, Taguchi method has been used to solve the optimization problem.
