Investigation of Die-Sinking EDM on SS316 Material with Various Tool Electrode for Enhanced Machining Performance—A Review

EDM is a widely used unconventional machining process employed to create intricate shapes in conducting materials. This study explores the application of Electro-Discharge Machining (EDM) on SS316 using various electrode materials. EDM enables the machining of challenging hard materials, bypassing the limitations of conventional methods. The selection of suitable electrodes is essential to achieve a good material erosion rate and surface finish. Electric parameters such as current, Pon (Pulse-on) and Poff Pulse-off) time is used in combination with other parameters like gap voltage, dielectric, and cutting depth. The primary objective is to focus on evaluating the material removal rate (MRR), tool wear rate (TWR), and surface roughness as observations to quantify the effectiveness of EDM. This study aims to enhance EDM performance by optimizing machining parameters for improved MRR, TWR, and surface roughness.
