This paper explores the EDM machinability of a nickel-based superalloy Inconel 690. It explores optimization of critical parameters like discharge current, pulse duration, and voltage to enhance machining efficiency. Key outcomes include the analysis of Material Removal Rate (MRR), Tool Wear Rate (TWR), and surface roughness. Results show that EDM is indeed a feasible process for machining Inconel 690, thus providing insight into its thermal and mechanical behavior during the process, while addressing challenges posed by toughness and corrosion resistance.The results show that EDM is a suitable method to machine Inconel 690, overcoming its inherent toughness and work hardening. The knowledge gathered in this study contributes to greater efficiency and precision when machining superalloys in high-stress applications.
