As the advancement in the technology some new material are comes in a trend which offers high strength, hardness and resistance to heat. Some of the materials are titanium, tungsten carbide boride etc. These materials are difficult to machine. A Die Sinker Electrical Discharge Machining (EDM) is a non-conventional and popular machining method. It is used for manufacture punches, dies and press tools because of its capability to produce complicated, intricate shapes and used for machining hard materials. Some common factors like Pulse on time, pulse off-time, current and voltage affects the quality of the final product. The objective of the present study is to optimize the value of the input parameters for material removal rate (MRR), tool wear rate (TWR). TaguchiÃ¢â?¬â?¢s method was used for conducting the experiment. Stainless steel 410 possess high strength, hardness and toughness and selected for experimentation. Copper was used as electrode material. Starting from identification of value of the input parameters, experiments were performed using L9 orthogonal array. After conducting the experiments, the results were analyzed with the help of MINITAB 16 software. After conducting the experiment it was analyzed that the optimize conditions found for MRR & TWR were, discharge current (15 A), pulse-on time (45Ã?Â?s).
