Roughness). Examine the varied effects of various input factors and analyse their impact on output process parameter, as well as determine their relative relevance. This is accomplished by using an L9 orthogonal array based on the Taguchi method to investigate their major effects as well as interaction effects. Optimization to find the best values for the input process parameters.
are challenging to obtain using traditional manufacturing procedures, are often made using electrical discharge machining (EDM), a non-traditional machining technique. The current, pulse on time, and pulse off time are the input parameters in this study, whereas the MRR and surface roughness are the output parameters. The experiment is designed according to Taguchi L9 orthogonal array with three different level of each input parameter. For result interpretation, analysis of variance (ANOVA) was conducted and optimum parameters selected on the basis of the signal to noise ratio, which confirms the experimental result. Find out most important role of input parameter on output parameter. Experiment will be performed on profile such as Flat, Concave, Convex of Inconel 800. Tangible observation will be analyzed with parameters like MRR, Surface roughness test. Conclusion will be displayed in durability of Inconel 800 with respect to Electric Discharge Machine.

1. INTRODUCTION Electricity discharge The unconventional machining process known as machining involves the removal of material by use of the thermal energy of a spark. This is achieved through a series of electrical ejections that occur in recurrent sequences between a small gap between an electrode and the work piece. For cutting electrically conductive hard metals and alloys, EDM is widely utilised in the die-making, automotive, and aerospace sectors. Electrode machining (EDM) is a technique that shapes metal sections by repeatedly ejecting an electrical current between a tool (cathode) and a work piece (anode) in an environment of 1. dielectric liquid, therefore removing debris and unwanted 2. material. In this machining technique, the anode refers to the work piece connected to the positive terminal and the cathode to the negative terminal. Some examples of dielectric fluids are kerosene, transformer oil, and distilled water.
