| Summary: | This study investigates the optimization of machining parameters in Electric Discharge Machining (EDM) for stainless steel (SS-304) using cast copper and pure copper electrodes. The primary objectives were to minimize surface roughness (SR) and maximize material removal rate (MRR) by varying pulse current (Ip), pulse duration (T-on), and pulse interval (T-off). Using the L9 orthogonal array of the Taguchi method for experimental design and Grey-Taguchi method for optimization, the results showed that pure copper electrodes achieved a maximum MRR of 3.1 g/min and a minimum SR of 5.29µs, outperforming cast copper electrodes, which yielded an MRR of 2.8879 g/min and an SR of 6.18 µs. ANOVA analysis revealed that discharge pulse current had the greatest impact on MRR and SR for cast copper, while pulse current was relatively significant factor for Cast and pure copper. It was concluded that machining SS-304 with pure copper electrodes provides the best overall performance for both MRR and surface quality. |
