K Harinarayana, N. Nagabhushana Ramesh, K. Rajendra Prasad, T. Anjenyulu


The Electro Discharge Sawing (EDS) process is an adjusted Electro Discharge Machining (EDM) procedure to acquire high material evacuation rates in sawing of expansive bar stocks and billets of high quality materials. The impact of heartbeat current heartbeat times, kind of electrolyte and work material on machining rates and surface unpleasantness are dissected. For this unpredictable framework with huge number of elements influencing its execution, the exploratory arrangement was chosen on Taguchi strategy for orthogonal clusters. An orthogonal exhibit of L8(24) was chosen for the four variables set at two levels and assigned as Low and High . For the most part higher machining rates are related with higher unpleasantness and this was seen with water electrolyte contrasted with silicic corrosive pop. However on account of work materials aluminum showed higher disintegration rates yet bring down harshness contrasted with HSS. Generally the impact of work material was most noteworthy on machining rate took after by electrolyte , current and heartbeat times. Be that as it may, for surface unpleasantness the request of impact was beat current, work material, electrolyte and heartbeat times. Impact of work material is subject to which warm property is more compelling out of warm conductivity and enthalpy of softening.
