Application of Taguchi, Fuzzy-Grey Relational Analysis for Process Parameters Optimization of WEDM on Inconel-825


Process parameters optimization of multiple response characteristics of WEDM on Inconel-825 super alloy using FuzzyGrey relational analysis is presented in this paper. Response characteristics such as MRR, surface finish and spark gap are optimized during wire EDM operation. Process parameters including pulse on time, pulse off time, corner servo voltage, flushing pressure, wire feed, wire tension, servo feed and spark gap voltage are investigated using Taguchi mixed L36 orthogonal array. These response characteristics are studied and examined using grey-fuzzy approach and optimal combination of influential input parameters are discovered. Based on the results of verification experiments it is concluded that Taguchi, Fuzzy-Grey Relational Analysis can efficaciously be used to find the optimal combination of influential input parameters of WEDM. Hence, this paper supports that the suggested approach can be a useful tool to ameliorate the performance of WEDM on Inconel-825.
