Abstract

Electrical discharge machining is a non-traditional machining process which is used to machine the hard and complex material which cannot be machined by conventional methods and is being labelled as most efficient method for machining most conducting hard materials. Hence, plays a major role in machining of dies, tools etc. even made of tungsten carbides, satellites or hard steels. But nowadays EDM in gaseous dielectric medium is in developing phase for research and development in green manufacturing processes. The Dry electrical discharge machining (EDM) uses gas as a dielectric fluid in place of liquid dielectric medium. It is a technology that has the potential to replace conventional liquid based EDM, owing to its low tool electrode wear, thin recast layer, and environmental friendliness. Super alloy because of their excellent mechanical properties are widely used in many industries and has many industrial applications. Due to its high strength at elevated temperature super alloys are very difficult to machine by using other convectional machining process. Electrical discharge machining (EDM) is an alternative competitive process to machine super alloys by electrical erosion. This study was carried with a sole aim of finding the effect of different input parameter while machining with Dry EDM, as the development of Dry EDM technology enhance the performance parameters such as material removal rate (MRR), Low tool wear rate (TWR), thin recast layer with a perception of bringing revolution in modern machining processes.
