AHP-DENG’S Similarity Based Optimization of WEDM Process Parameters of Al/SiCp Composite

Abstract

Aluminium based Metal Matrix Composite material properties such as light weight, high strength and corrosion resistance etc. makes AMMC as a demanding material in the marine, automobile, aerospace, defense, and sports industries. However, the presence of abrasive reinforcements in the Aluminium Matrix causes rapid tool wear or failure and leads to an increase in machining cost, production time and poor quality of machined components. Hence the Wire Electrical Discharge Machining is the best one to overcome such drawbacks. The present paper focused on the optimization of WEDM in machining of (Al6061/2%SiC/3μm) Aluminium Metal Matrix composite using AHP-DENG’S Method. In this work, Orthogonal Array L18 Taguchi Experimental design is used by considering the process parameters such as Wire Type, Pulse ON Time, Pulse OFF Time, Wire Feed, and Sensitivity to perform the WEDM experiments for considered responses such as Cutting Speed, Material Removal Rate, Surface Roughness and Dimensional Deviation.
