Electric discharge machining (EDM) is non-conventional machining processes that involves a transient spark discharges through the fluid due to the potential difference between the electrode and the work piece. The aim of this project is to determine the proper machining conditions for machining EN-19 and Nickel Plated EN-19 work pieces using electrical discharge machining (EDM). Basically, improper choice of parameter in EDM machine may result a few problems like the machine may cause of poor machining performance and it will decrease the accuracy of the products and incurs a lot of cost. The aim of this project is to determine the optimal machining parameters for machining work pieces using electrical discharge machining (EDM). Intensity of current, pulse on time and pulse of time were used as process parameters. This paper explores the characteristic of electric discharge machine (EDM) that is tool wear rate (TWR) and material removal rate (MRR) by using different workpiece materials namely En-19 and Nickel Plated En-19 alloy steel and copper as a tool material in order to increase the understanding of EDM processes. To achieve this project objective, an experimentation was done where the approach used was response surface methodology in which a well-designed experimental scheme named box behnken design was used to reduce the total number of experiments into 15 for each workpiece material. A second order empirical model is developed to predict the MRR and TWR. Finally ANOVA analysis is done to validate the model developed.

Abstract. The paper presents the experimental analysis and multi-response optimization of EDM process parameters during machining of Nimonic 90 work material. The experiment has been conducted at different parametric setting considering discharge current, pulse-on-time and pulseoff-time as process parameters. Taguchi L9 orthogonal array has been used for experimental design. The effect of various parameters on response such as material removal rate and surface roughness has been studied with the help of suitable plots. The Grey Relational Analysis has been utilised for obtaining the optimal parametric combination.

-Electrical Discharge Machining (EDM) is a thermo-electrical based non-contact material removal process for machining of the electrically conductive difficult-to-machine materials. The machinability of the EDM process is not affected by mechanical and physical properties of the workpiece materials. Even though, its performances are highly affected by the tool materials and their designs. Most of the research papers refer to enhance the productivity of the EDM process without considering the effect of the parameters related to the tool electrodes. Generally, the tool wear is the well known phenomenon of the EDM process that affects the plasma formation as well as surface quality and productivity. The aim of the present study is to summarize a report on the published works related to the tool electrodes materials, designs and their effect on the performances of the EDM process. Instead of this, the present paper also focuses to future research scope in the same field and discussed in the brief.
