Inconel 625 possesses excellent mechanical, chemical, and physical properties thus commonly used in different sectors. Due to its wide use, it becomes important to investigate its mechanical characteristics under die-sinking EDM. In this research, an empirical model is constructed to investigate the optimal parametric setting of die-sinking EDM. The experimental runs are developed using a Taguchi design. It has been observed from the analysis that peak current followed by pulse on time is the most significant parameter for MRR followed by pulse on time. However, the SR gives significant results on the pulse on time. The confirmatory test is conducted to validate the efficacy of the proposed method.
