Electric discharge machining (EDM) is a material removal process that is especially useful for difficult-to-cut materials with complex shapes and is widely used in aerospace, automotive, surgical tools among other fields. EDM is one of the most efficient manufacturing processes and is used to achieve highly accurate production. It is a non-contact thermal energy process used to machine electrically conductive components irrespective of the material’s mechanical properties. Studies related to the EDM have shown that the process performance can be considerably improved by properly selecting the process material and operating parameters. This paper reviews research studies on the application of EDM to different grades of stainless steel materials and describes experimental and theoretical studies of EDM that have attempted to improve the process performance, by considering material removal rate, surface quality and tool wear rate, amongst others. In addition, this paper examines evaluation models and techniques used to determine the EDM process conditions. This review also presents a discussion on developments in EDM and outlines the likely trend for future research.

“…The emission concentrations increased by the increase in pulse width due to high heat energy, evaporation, and metal melting are directly varied to the quantity of pulse heat by pulse time (Evertz et al 2006;Sivapirakasam et al 2011;Suthangathan Paramashivan et al 2012;Thiyagarajan et al 2012). The high heat debris particles will react with water which causes the smoke by long availability of spark in the cutting zone (Spedding and Wang 1997;Pandey et al 2015;Sadagopan and Mouliprasanth 2017).…”

Wire-cut electrical discharge machining (WEDM) is the highly essential unconventional electro-thermal machining process to cut the contour profile of hard materials in modern production industries. The various environmental impacting wastes (by evaporating and reacting hydro-carbon dielectric fluid) are produced during the WEDM process and these are harmful to the machine operators. These wastes are minimized by a near-dry WEDM process wherein the pressurized air mixed with a small amount of water is used as a dielectric substance. In this research, influences, and contributions of machining parameters such as air pressure, mixing water flow rate, spark current and pulse width on gas emission concentration (GEC), materials removal rate (MRR), and relative emission rate (RER) of sustainable near-dry WEDM process have been optimized by Taguchi analysis. RER is investigated to analyze the effects of machining factors on gas emission and machining rate combinedly. It was revealed that the maximum air pressure and flow rate of mixing water have significantly been promoting the sustainable near-dry WEDM process.
