“…Variables on the material removal rate (MRR) in die-sinking EDM of EN19 material for four processes (Pulse on time, pulse off time, discharge current and gap voltage) with electrolytic copper use as the electrode material. The different combinations of process parameters and by analysis of variance (ANOVA) found that pulse off time, discharge current, gap voltage and the interaction terms are significant whereas the pulse on time has almost negligible effect on MRR 1.45% is the error between the predicted and experimental MRR value was found to be very effective as shown in this studied [11].…”

Electrical Discharge Machining (EDM) is a widespread Nontraditional Machining (NTM) processes for manufacturing of a complicated geometry or very hard metals parts that are difficult to machine by traditional machining operations. Electrical discharge machining is a material removal (MR) process characterized by using electrical discharge erosion. This paper discusses the optimal parameters of EDM on high-speed steel (HSS) AISI M2 as a workpiece using copper and brass as an electrode. The input parameters used for experimental work are current (10, 24 and 42 A), pulse on time (100, 150 and 200 µs), and pulse off time (4, 12 and 25 µs) that have effect on the material removal rate (MRR), electrode wear rate (EWR) and wear ratio (WR). A Minitab software environment was used to adopt Taguchi method to analyze the effect of input on output parameters of EDM. The results of the present work showed that the best of MRR in copper and brass electrodes with (current 42 A, pulse on time 100 µs and pulse off time 25 µs) are (84.355×10-3 g/min) and (43.243×10-3 g/min) respectively, and the MRR predicted by Taguchi are (86.1751×10-3 g/min) in copper electrode by using the parameters with (current 10 A, pulse on time 200 µs and pulse off time 25 µs) and (43.2979×10-3 g/min) in brass electrode at current 42 A, pulse on time 100 µs, and pulse off time 25 µs. The lowest EWR occurs with a value of (1.4510×10-3 g/min) with (current 10 A, pulse on time 100 µs, pulse off time 4 µs) variables when using a copper electrode. The highest WR (2.602508) was found for the brass electrode with (current 24 A, pulse on time 200 µs, pulse off time 4 µs) variables.

“…Since a long time ago, researchers have attempted to employ non conventional machining process such as EDM, WEDM (Wire EDM), and AWJM (Abrasive Water Jet Machining) which are used for machining hard and high strength alloys [1]. The origin of electrical discharge machining goes back to 1770 when English scientist Joseph Priestly discovered the erosive effect of electrical discharges on metals [2].…”

The Al 6061 alloy based Al- SiC metal matrix composite is rated as one of the most commonly used Metal Matrix Composites (MMCs) today. The MMC specimens studied in this research work were fabricated with the stir casting process. This research work studies important parameters in the wire electric discharge machining of Al-SiC 6061 MMC. We employed Taguchi approach to study the machining parameters during the machining process and to minimize the surface roughness values of the surfaces obtained by Wire EDM (Wire Electric Discharge Machine) machining. We found out that out of the seven factors used in this study, gap voltage during the wire EDM machining is the most prominent factor which influences the obtained surface roughness values. Comparatively, a very low value of surface roughness (Rq) was obtained by us during confirmation test by us

EDM (Electrical Discharge Machining) is a common non-traditional machining technique for manufacture geometry parts made of intricate or extremely rigid metals that are challenging to manufacture using conventional manufacturing techniques. Electrical discharge machining by utilizing electrical discharge erosion, classify the meaning of material removal (MR). This paper's main objective is to discuss the ideal EDM parameters in order to use high-speed steel as workpiece AISI M2 and with using brass & copper as electrodes. Pulse on-time are (100, 150, and 200 µs), Current (10, 24 and 42 A) and Pulse off-time (4, 12 and 25 µs) are the input parameters effect on the material removal rate (MRR) used in the experimental work. The present study's findings shown that the highest MRR with using copper & brass as electrodes with pulse on-time 200 µs, pulse off-time 12 µs and current 42 A, at (0.31284 g/min and 0.18769) respectively, and the lowest average value of the removed material was when evaluating current 10 A, Ton is 100 µs, Toff is 4 µs, at (0.05451g/min and 0.01898 g/min) respectively.
