“…It was noticed that various machining parameters influenced surface roughness and setting possible combination of these parameters was difficult to produce optimum surface quality. The influences of some machining parameters such as pulsed current [2][3][4][5][6][7][8][9], pulse time [2][3][4][5][6]8,9], pulse pause time [2,5,9], voltage [4,6], dielectric liquid pressure [4,6,8,10] and electrode material [11] have been examined. One study examined P20 tool steel and provided useful information the effects of some machining parameters on surface roughness, but the selected of pulsed current values was very low 1-8 A [12].…”

“…EDM process parameters can be divided into two categories, that is, electrical and non electrical. 28 Main electrical parameters are peak current, discharge voltage, pulse duration (pulse on-time T on ), pulse interval (pulse off-time T off ), polarity, electrode gap (spark gap) and pulse waveform. Non-electrical parameters include gap flushing, tool electrode rotation and workpiece rotation.…”

Turning by electrical discharge machining is an emerging area of research. Generally, wire-cut electrical discharge machining is used for turning because it is not concerned with electrode tooling cost. The process variant die-sinking electrical discharge machining can also be effectively used to generate free-form cylindrical geometries on difficult-to-cut materials with complex shapes at both macro and micro levels. The machining performance of electric discharge machine is defined and influenced by its process parameters, which significantly affects production rate and the quality of machined component. Thus, it is very important to select machining parameters and their levels cautiously in order to improve the outcome of the process. In this article, the authors have reviewed the research work carried out in the area of electrical discharge turning in the last decade for the improvement of material removal rate, surface integrity and roundness. In this review, various techniques reported by electrical discharge machining researchers on turning have been categorised in different electrical discharge machining variants. The article also discussed the future direction of research work in the same area.

“…Minimum wear of the electrode that removes the materials from the work piece by conducting the current is required in EDM applications. A number of researches have been made by adding various additives to the dielectric fluid in order to decrease the electrode wear rate, obtaining better results compared to pure fluids (Valentincic and Junkar, 2004;Luis et al, 2005;Wang et al, 1999). Volumetric relative wear has been observed in addition to the EW/MRR rates (Amorim and Weingaertner, 2004).…”
