Electrical Discharge Machining (EDM) process is based on thermoelectric energy between the work and an electrode. A pulse discharge occurs in a small gap between the work piece and the electrode and removes the unwanted material from the parent metal through melting and vaporization. The electrode and the work piece must have an electrical conductivity in order to generate the spark. Dielectric fluid acts as a spark conductor, concentrating the energy to a very narrow region. This paper proposes two methodologies to maximize the Material Removal Rate (MRR) and minimize the Surface Roughness (SR) in Electric Discharge Machining. First one proposes an optimization methodology for selection of best process parameters by considering four important operating parameters such as Discharge current, Source voltage, Pulse-on time and Pulse-off time and second one offers a new design of EDM namely Eco-Friendly Electric-Discharge Machining (E-EDM) using structured Innovation technique called TRIZ by replacing dielectric fluid and introducing ozonized oxygen into existing EDM design to eliminate harmful effects generated while machining by using dielectric fluid. Hope the proposed innovative eco-friendly EDM design using TRIZ inventive principles will definitely reduce environmental burden since Eco-friendly design is the need of the hour
