Abstract :In this study, the optimization of overcut in electrical discharge machining (EDM) processes, with a focus on the effects of various process parameters on machining performance, particularly when challenging materials such as Mirrax steel are investigated. A Taguchi-based experimental design was employed to systematically analyze three distinct copper-based alloy electrodes; CuCoNiBe, CuNi2SiCr, and CuCr1Zr under varying discharge currents (6 A, 12 A, 25 A), pulse on-times (50 μs, 100 μs, 200 μs), and pulse off-times (200 μs, 400 μs, 800 μs). It was found that overcut is significantly influenced by the electrode type, discharge current, and pulse duration, with the CuCoNiBe electrode exhibiting the highest overcut values. Analysis of Variance (ANOVA) was conducted to confirm the significant contributions of these parameters to overcut variability. This research contributes to a deeper understanding of the interplay between EDM parameters, in advanced manufacturing applications.
