Parametric Optimization of EDM Processes for Aluminum Hybrid Metal Matrix Composite using GRA-PCA Approach

Abstract

The optimized process parameter context using GRAPCA, demonstrates the enhancement of MRR by 172.5% and reduction in EWR and Ra by 64.17%, 34.4% respectively using Ip3Ton13Sg2ET2ES1 parameter settings against the initial assumed settings. The maximum contributors amongst all parameters were Ton and Ip (21%, 14.31%), followed by ET (12.4%), Sg (11.5%)by using Analysis of Variance (ANOVA).
