“…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].…”

“…There have been a great many publications regarding the quality of the surface finish achieved by wire-EDM. The influences of some machining process parameters such as pulsed current [2,[21][22][23][24][25][26][27][28], pulse-on time [21][22][23][24][25]27,28], pulse-off time [21,24,28], gap voltage [23,24,28], dielectric liquid pressure [23,25,27,29] and electrode material [30] have been thoroughly investigated. However, when seeking information about the effect of the wire feed rate on the surface roughness using wire-EDM, we found no authoritative public data available.…”

Electrical discharge machining is an old technology that has been used for old manufacturing processes. Nowadays, the modernized version of the machine is used to manufacture different objects using a wire feed. The parameters in which the machine operates have diverse effects on product quality and surface finish. This paper investigates the performance of a wire electrical discharge machining process for different wire feed rates. The process is a non-traditional machining method. Several tests have been performed considering a carbon steel 1017 and aluminum alloy 6060 machined via Wire-EDM. By using different wire feed rates (3 mm/min, 5 mm/min and 7 mm/min), the average surface roughness, R a , has been investigated in this study. Results show that the wire feed rate is a significant variable to the surface quality finish. The surface roughness of the test target materials increased as this variable increased. The present study recommends setting the wire feed rate as low as possible with the aim of improving results in the surface quality finish. The obtained results and some of the most necessary parameters affecting the manufacturing process of wire-EDM are briefly defined and are then discussed in detail in this study.

“…All these process parameters play a vital role in deciding machining characteristics like surface finish, energy consumption and efficiency (MRR) of EDM process. Researchers have reported that most influencing process parameters are discharge current [25][26][27][28][29][30][31][32][33][34][35], pulse on time [25][26][27][28][29][30][31][33][34][35], pulse off time [25,26,28,30,34,35] and dielectric liquid pressure [29,31,32,36].…”

Electrical Discharge Machine (EDM) is especially used for the manufacturing of 3-D complex geometry and hard material parts that are extremely difficult-to-machine by conventional machining processes. In this paper authors have reviewed the research work carried out in the development of die-sinking EDM within the past decades for the improvement of machining characteristics such as Material Removal Rate (MRR), Surface Roughness (SR) and Tool Wear Ratio (TWR). In this review various techniques reported by EDM researchers for improving the machining characteristics have been categorized as process parameters optimization, multi spark technique, powder mixed EDM, servo control system and pulse discriminating. At the end, flexible machine controller is suggested for Die Sinking EDM to enhance the machining characteristics and to achieve high-level automation. Thus, die sinking EDM can be integrated with Computer Integrated Manufacturing (CIM) environment as a need of agile manufacturing systems.
