Abstract- Electrical Discharge Machining is nontraditional process which is used for making complex 3D shapes and can be machined using a simple shaped tool electrode. D3 is a high carbon-high chromium steel developed for applications requiring high resistance to wear or to abrasion and for resistance to heavy pressure rather than to sudden shock. Because of these qualities and its non-deforming properties, D3 is unsurpassed for die work on long production runs. In Electro Discharge Machining in order to determine the effect of 4 input parameters those are namely: Pulse on Time (Ton), Discharge Current (IP),Gap Voltage (Vg) and Duty Cycle(t) on performances as Material Removal Rate (MRR),Tool Wear Rate (TWR),Radial Overcut (RO) on Electro Discharged Machined Surface. In the present study the experiment was conducted in an experiment matrix of 27 runs designed using a L27 Orthogonal Array of Taguchi Design of Experiment and grey relational analysis method is subsequently applied to determine an optimal parameter setting. All this experimental observations and subsequent data analysis study assures that GRA method is a powerful and most versatile tool which can manipulate the input data as per requirement and comes with results that can be used to have best multi performance in respective concerns
