Abstract: ABSTRACT newline newline newline newlineTechnologically advanced industries of the modern world such as space research, missile, automobile, nuclear, medical, mould tools and die making industry demand use of complex and intricately shaped components made from exotic alloys and high strength and temperature resistive materials. The traditional machining processes, in spite of recent technological advancements are inadequate to machine these materials from the standpoint of economic production. Besides, machining of these materials to complex shapes with the traditional machining processes is difficult, time consuming and sometimes impossible. For meeting these challenges, non-traditional machining processes were evolved and they are not limited by hardness, toughness, and brittleness of materials and can produce any intricate shape on any work material by suitable control of various machining parameters of the processes. EDM is one of the most extensively used non-conventional material removal processes. EDM is a thermoelectric Process in which material is removed from work piece by erosion effect of series of electric discharges between tool and work piece immersed in a dielectric liquid. The electric energy induced by electric sparks converts into thermal energy resulting in high temperature which melts and evaporates the work piece and tool electrode. The eroded particles are flushed away by dielectric liquid. Physical and metallurgical properties do not create any limitation for the materials to be machined on EDM as there is no physical contact between tool and work piece. newline newline newlineInconel 625 materials are widely used in chemical, aircraft and shipbuilding industries because thermal resistant retaining mechanical properties up to 700°C. On the other hand, they are very difficult to machine, due to their high shear strength, work hardening tendency, highly abrasive carbide particles, tendency to weld and form build- up edge and low thermal conductivity. For all these alloys high temperature characteristics translat
