Electro-discharge machining (EDM) is a nonstandard electro-thermal machining technology used to produce geometrically complex or hard material parts that are highly challenging-to-machine by traditional machining methods. By igniting quick and repeating spark discharges between the tool and work piece separated by a narrow gap of around 0.01 to 0.50 mm, the method allows for the controlled erosion of electrically conductive materials. This void is filled with a dielectric fluid, either by flooding or immersion. The goal of this study is to evaluate the optimal process parameters of Argon gas...
