“…In another investigation [203], an optimization system to generate the optimal process parameters of EDM was proposed. Han et al [175] developed a simulation method for wire EDM. Additionally, Yadav et al [201] developed a model to represent the thermal stress of the EDM process, and Tsai et al [109] developed a semi-empirical model for the surface finish of machined workpieces in EDM.…”

Electric discharge machining (EDM) is one of the most efficient manufacturing technologies used in highly accurate processing of all electrically conductive materials irrespective of their mechanical properties. It is a non-contact thermal energy process applied to a wide range of applications, such as in the aerospace, automotive, tools, molds and dies, and surgical implements, especially for the hard-to-cut materials with simple or complex shapes and geometries. Applications to molds, tools, and dies are among the large-scale initial applications of this process. Machining these items is especially difficult as they are made of hard-to-machine materials, they have very complex shapes of high accuracy, and their surface characteristics are sensitive to machining conditions. The review of this kind with an emphasis on tool and die materials is extremely useful to relevant professions, practitioners, and researchers. This review provides an overview of the studies related to EDM with regard to selection of the process, material, and operating parameters, the effect on responses, various process variants, and new techniques adopted to enhance process performance. This paper reviews research studies on the EDM of different grades of tool steel materials. This article (i) pans out the reported literature in a modular manner with a focus on experimental and theoretical studies aimed at improving process performance, including material removal rate, surface quality, and tool wear rate, among others, (ii) examines evaluation models and techniques used to determine process conditions, and (iii) discusses the developments in EDM and outlines the trends for future research. The conclusion section of the article carves out precise highlights and gaps from each section, thus making the article easy to navigate and extremely useful to the related research community.

“…Authors simulated the WEDM process by using different techniques. Han et al [101] simulated the WEDM process by using parametric programming for discharge location, workpiece erosion, and wire vibration. A thermo-analysis was carried out by using Finite Element Method (FEM) to understand the change in surface morphology while varying pulse duration [118].…”

Wire Electrical Discharge Machining (WEDM) is an electrothermal non-traditional machining process used for machining electrically conductive materials that are difficult to machine. Material removal in WEDM is by means of spark erosion. WEDM is proven to be the alternative for producing complex parts with higher degree of dimensional accuracy and better surface finish. Over the years, a significant amount of research was globally carried out to explore the WEDM process capability. This paper aims to explore the research work carried on parametric influence of WEDM process variables on various output performance measures. The paper also highlights various modelling techniques to predict optimal machining conditions and explore the feasibility of applying WEDM process to machine advanced materials. Combined technology that benefits from the virtues of WEDM and conventional method is also highlighted in this paper. The final section discusses the development and possible research trend in WEDM process.

“…This flushing aims not only to flush the debris away from the discharge gap, but also to introduce fresh working fluid for dielectric recovery of the gap and to cool down the wire electrode and the workpiece. Some studies on the fluid flow in the EDM gap and the simulations were done [4][5][6][7]. However, the flow field in the wire EDMed kerf has not yet been sufficiently made clear.…”

Debris exclusion from the wire EDM gap has been conventionally done by jet flushing using nozzles but the debris stagnation area always presents near the wire with the conventional method. In this study, a new flushing method using tilting nozzle to wire running direction to reduce the debris stagnation in the kerf was proposed on the base of simulation results by computational fluid dynamics (CFD) analysis. The simulations and experiments clarified that the tilting jet flushing nozzle could decrease the debris stagnation area in the kerf and leads to smoother debris exclusion, resulting in higher removal rate. Furthermore, the wire deflection caused by hydrodynamic force due to the jet flushing was calculated by a structural analysis using the distributions of pressure acting on the wire surface by jet flushing flow obtained by the CFD analysis.
