Parametric Study of MRR and Surface Integrity for 304 Stainless Steel in EDM

304 stainless steel is a promising material that is extensively used in manufacturing industries. Herein, the influence of the machining parameters electrical discharge machining (EDM) on the material removal rate (MRR) and surface integrity of 304 stainless steel are investigated. The improvement in the MRR with the optimum experimental conditions compared to the initial condition is 64% by the Taguchi methodology. The topography of the section surface produced by EDM with different pulse durations is studied. We founded that the section surface integrity becomes poorer with the increase in the pulse duration.
