Optimization of multiple-machining characteristics in wire electrical discharge machining of punching die using Grey relational analysis

Kamal Kumar, Ajai Jain, Sandeep Grover

Abstract

This study presents optimization of performance characteristics in wire electrical discharge machining (WEDM) usingTaguchi method and Grey relational analysis. Performance characteristics (cutting speed, surface roughness and dimensionallag) were investigated during rough cutting operation. Process parameters (peak current, pulse-on, pulse-of f, wire speed and wiretension) were investigated using mixed L
