Multi-Objective Decision Making Optimization for Electro Discharge Machining Process of Al-4.5Cu-SiC Composite Using Fuzzy-Topsis

Abstract

In this paper, discuss the performance of Fuzzy-Topsis in electro discharge machining process on ex-situ developed Al-4.5Cu-SiC composite material. The design of experiment for this experiment was planned by response surface method and investigate the sensitivity of different EDM performance attributes in the variation of multiple process parameters such as pulse on, peak current, duty cycle and weight fraction of SiC_P. Scanning electron microscope (SEM) analysis is conducted to see the particle distribution and EDM surface quality of the developed specimen.  The results indicate that the duty cycle is the most influential factor and pulse on time is the less influential factor in this problem.
