Abstract
Wire Electrical Discharge Machining (WEDM) is well suited advanced machining process for cutting complex and intricate geometries of almost all materials having good electrical conductivity. Stainless steel SS304 (SS304) is ubiquitously preferred in various industries not limited to medical, semiconductors, electronic, Tool and die industries, and aerospace industries. Processing of stainless steel via traditional route is tedious as it has less thermal conductivity and more affinity towards built up edge formation, it further leads to poor surface conditions and extreme tool wear. In the current work, an attempt is made to study the parametric effect on surface characteristics and material removal rate of SS304 in WEDM where pulse timings like on time and off time along with current and wire feed were taken as input factors. The surface roughness and material removal rate were considered as output factors. The experimental results were evaluated through Taguchi methodology. Besides the surface morphology of the material after WEDM machining was investigated.
