“…This action may happen thousands of times per second. The amount of clamping pressure required to hold the small, thin and fragile parts is minimal, which in turn minimizes the workpiece distortion and will prevent damage to the parts [1][2][3]. The surface finish, dimensional accuracy and time required to complete a job is extremely predictable and also makes it much easier to quote.…”

Micro-wire-cut electrode discharge machining (EDM) is an emerging manufacturing process in the field of micro-manufacturing to fabricate the complex profiles of micro-components. It is a complex process involving various process parameters such as pulse on time, pulse off time, wire speed, wire tension and current. In addition to micro-fabrication, this process can also be extended in the field of tool design and developments such as dies, moulds, precision manufacturing, contour cutting, etc., where complex shapes need to be generated with high-grade dimensional accuracy and surface finish. In this research work, an attempt is made to investigate the effect of process parameters on the output variables such as material removal rate (MRR), surface finish and the cutting width (kerf) of wire-cut EDM for duplex stainless steel (DSS). Scanning electron microscopy (SEM) has been used to capture the images of the kerf width, and the measurements are taken with the help of the welding expert system and software. An optimization technique (Taguchi method) has been employed to identify the optimum parameters of the micro-wire-cut EDM process for cutting 2205 grade duplex stainless steel. The effect of each control parameter on the performance measure is studied individually using the plots of signal to noise ratio.

“…The dielectric medium acts as a deionizing medium between the electrode and the work piece, thus providing the optimal conditions for spark generation and also flushes the debris formed in the spark gap [5,6]. A comparative study of fatigue strength and other surface integrity aspects generated by grinding and Wire EDM of titanium alloy 9 Ti-6Al-4V was recently reported in with a conclusion that a standard Wire-EDM process with instabilities has a better fatigue life than a standard grinding process [7].…”

With continuous evolution of NiTi file system it has become a challenge to choose between the right system for individual clinical scenario. The various thermomechanic procedures and the improvement of composition of the alloy that is used in manufacturing NiTi files are aimed to improve the flexibility of NiTi files. Improved flexibility of NiTi files would minimize the intracanal irregularities such as canal transportation and would ensure an increase in the success of root canal therapy. Technically speaking there is a phase shift from milling of alloy to electro discharge machining of alloy.Electro-discharge machining (EDM) is a non-contact thermal erosion process that partially melts and evaporates the wire by high-frequency spark discharges. There is significant difference in surface architecture of nickel titanium after thermal treatment. Electro discharge machining gives better fatigue resistance property hence more predictable outcome.

“…In another study, researchers were machined the Ti6Al4 alloy with grinding and WEDM separately, and the bending fatigue lives of both surface structures were compared. Although the roughness of the EDM treated specimens is high, it has been found to exhibit higher fatigue strength [2]. In a study of fatigue tests at loads ranging from 1470 to 2401 N with the aim of determining the fatigue lives of steel specimens treated with EDM SKD11 [3]; A fatigue test was also performed for comparison of the surface polished SKD11 sample.…”
