“…The authors reported the optimal setting combination as Ip (discharge current) of 7 A, Ton (pulse-on time) of 200 µs, τ (duty factor) of 90%, and Fp (flushing pressure) of 0.4 kg/cm 2 , and the experimental values of responses were obtained as MRR of 13.9600 mm 3 /min, TWR of 0.0201 mm 3 /min, SR = 4.9300 µm, and circularity = 0.8401. Furthermore, Haddad and Tehrani [119] studied the influence of machining parameters on the MRR in the cylindrical wire electrical discharge turning process. A statistical design of the experimental method was utilized to study AISI D3 (DIN X210Cr12) tool steel.…”

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.

“…This causes the debris to be removed more easily; as a result, fewer short-circuit in discharging gap (Prihandana et al, 2009). Haddad and Tehrani (2008) (Haddad and Tehrani, 2008) presented an investigation on the effects of various machining parameters (power, voltage and pulse on/off time along spindle rotation) on material removal rate (MRR) in cylindrical wire electrical discharge turning (CWEDT) process. Uhlmann and Domingos (2013) investigated the effects of the vibration assisted EDM of tool on seal slots in high temperature resistant material for turbine components.…”

In this paper, an attempt has been made to review the literature on strategies formulated and tested in ultrasonic vibration assisted electrical discharge machining (USEDM). The strategies for optimisation of EDM performance include flushing, dimensional accuracy, cavitation, surface morphology, polluted gases and chemical effects etc have been highlighted. The major performance controllable parameters in EDM process have also been discussed in this study. The main emphasis is given on classification of USEDM process on the basis of mode of ultrasonic vibration (UV) action imparted to EDM system, which includes a tool, work piece and the dielectric medium. The ultimate purpose of this study is to generalise the variable relationships of various proposed strategies, which may be applied in industries to improve the performance of USEDM. At the end of this study, some limitations of implementing ultrasonic vibration in EDM have been discussed. and has an illustrious, diverse and rich experience in the fields of academic, research and modern industry. His area of research includes advanced manufacturing processes and industrial engineering. He has survived seven PhD and more than 40 MTech Theses. He has published more than 150 research papers in peer reviewed journals and international conferences.

“…A mathematical model for MRR of the CWEDT process for free-form cylindrical geometries has been derived by Qu, Shih, and Scattergood (2002a). The effects of CWEDT parameters such as power, voltage, pulse off time and spindle rotational speed have been analysed on MRR by using analysis of variance (Haddad and Tehrani 2008b). On the other hand, preliminary experiments conducted by Janardhan and Samuel (2010) to compare the WEDM and WEDT processes disclosed that MRR is less in WEDT than in WEDM.…”

Cylindrical wire electrical discharge turning (CWEDT) is a special form of wire electrical discharge machining (WEDM) process, which uses submerged rotation spindle as a clamping device for workpiece rotation in order to produce cylindrical parts. This study aims at determining influence on material removal rate (MRR) of CWEDT as an objective function. In the preliminary experiments, the widely used X5CrNi18-10 (DIN) and hard machinable S390PM (DIN) were used. The results of preliminary experiments showed that the type of steel is not the factor that has a significant influence on MRR. Pulse maximum current, pulse pause time, rotation speed, length of discharge area and cutting radius were used in MRR mathematical modelling by neural network programming. The results of the study exhibit that among the machining parameters, the pulse maximum current has the strongest influence on MRR. When the pulse maximum current increases, MRR increases as well. The discharge area length has an influence on MRR only on higher pulse maximum current values, and by the increase of the discharge area length, the MRR also increases. The derived mathematical model for MRR, which was finally validated and tested, enables calculation of complex cylindrical part production machining time for the given experimental set-up condition.
