“…L. Chen et al [7] studied about various parameters of EDM like electrode material, pulse duration, discharge current and polarity using two materials namely silicon carbide and tungsten carbide as work piece and copper and copper tungsten as a tool material. They concluded that MRR is directly proportional to current and pulse duration, Electrode wear increased up to 80 µs then started decreasing with increase in pulse duration.…”

“…It is because of correct flushing of the debris with sufficient pulse off time duration; which would otherwise make the spark contaminated and unstable, thus decreasing MRR [7]. d) Results of TWR with Nickel Plated En-19 From the ANOVA Table (6) above, again, small P values for model terms indicate that their contribution is significant to the model.…”

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.

-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.

“…The removal rate and energy efficiency were found higher than those of conventional EDM in which there is only one discharge point for each pulse. Chen et al [113] designed a new mechanism of cutting pipe combined with electrical discharge machining. This new mechanism was designed with multi electrode system controlled by planet gear system in die sinking EDM as shown in Fig.…”

Electrical discharge machining (EDM) is one of the earliest non-traditional machining processes. EDM process is based on thermoelectric energy between the workpiece and an electrode. Material removal rate (MRR) is an important performance measure in EDM process. Since long, EDM researchers have explored a number of ways to improve and optimize the MRR including some unique experimental concepts that depart from the traditional EDM sparking phenomenon. Despite a range of different approaches, all the research work in this area shares the same objectives of achieving more efficient material removal coupled with a reduction in tool wear and improved surface quality. The paper reports research on EDM relating to improvement in MRR along with some insight into mechanism of material removal. In the end of the paper scope for future research work has been outlined.
