EDM (electro diffraction machining) is a standard procedure for producing finished products (EDM). When utilizing EDM, high-frequency sparks are used to remove electrode material from a work piece submerged in dielectric. the MRR is a critical indicator for the effectiveness of the EDM process (MRR). Work piece electrode surface size affects the machining settings that generate the optimum MRR the most. Monel 400's potential uses need a thorough investigation of the machining process. An overview of Taguchi optimization for EDM & SR on Monel 400 is provided in this study in order to enhance the process parameters. Work piece thickness has been established as the controlling element. During the machining process, surface roughness and material removal rate are crucial. The Design of Experiment (DOE) is made easier with the aid of Taguchi's L9 Orthogonal Array (OA). MRR and SR analyses used input characteristics such as pulse-on (T-ON), pulse-off (TOFF), and current (I) to analyze process performance. Achieving maximum Material Removal Rate and minimum Surface Roughness is the ultimate goal of optimizing (SR).
