“…During WEDM, the workpiece is sunken in dielectric fluid to generate a favourable surrounding for electric spark formation to take place [5, 6, 7]. During the process, spark erosion occurs in the neighbourhood of electrodes and form anticipated two/three dimensional shapes based on input process variables by melting/evaporating the workpiece [8, 9]. The difference between WEDM and conventional EDM is the use of thin wire electrode (Ø 0.05–0.3 mm) in the former case.…”

Non-conventional machining process for instance, wire electrical discharge machining (WEDM) of titanium alloys is gaining attention due to non-contact nature of this process. To deepen the understanding in this area, this study investigates surface generation, kerf width, discharge gap, material removal rate and wire degradation during WEDM of Ti6Al4V alloy. Pulse on time (4–10 μs), flushing pressure (7–18 MPa) and wire tension (800–1700 gf) were varied and resulting influences on output parameters were analysed. It was found that, machined surfaces consist of multi-layered recast layer with the presence of cracks, holes as well as traces of materials from electrode wire. The composition and roughness of the machined surface varies slightly with respect to machining condition without following any trend. In addition, deformation and morphology of deformed wire electrode after the WEDM process was also reported in this study.

“…During EDM, the workpiece is dipped in dielectric liquid to create a encouraging surrounding for electric sparks to happen (Pramanik et al, 2018;Pramanik et al, 2018;Pramanik and Littlefair, 2016). Spark erosion takes place in the vicinity of electrodes and forms expected three/two dimensional figures by melting/evaporating the workpiece material (Kumar et al, 2018;Pilligrin et al, 2018;Pramanik et al, 2019). It is a promising technique for various materials irrespective of its toughness and hardness, as long as those are conductive electrically (Pramanik, 2014a;Pramanik et al, 2018).…”

“…The authors emphasized that the vibration significantly helped to remove the debris and improve the flushing as well as the machining stability. The influences of the different tool materials on the MRR, TW, TAP, OC, and roughness of the drilled SS 316L were analyzed [21]. The outcomes revealed that the tungsten tool contributed to the lowest values of the TWR as well as OC and the MRR could be improved using the copper tool.…”

The electrical discharge drilling (EDD) process is an effective machining approach to produce various holes in difficult-to-cut materials. However, the energy efficiency of the EDD operation has not thoroughly been considered in published works. The aim of the current work is to optimize varied parameters for enhancing the material removal rate (MRR), saving drilled energy (ED), and decreasing the expansion of the hole (HE) for the EDD process. Three advanced factors, including the gap voltage adjustor (GAP), capacitance parallel connection (CAP), and servo sensitivity selection (SV), are considered. The predictive models of the performances were proposed with the support of the adaptive neuro-based fuzzy inference system (ANFIS). An integrative approach combining the analytic hierarchy process (AHP) and the neighborhood cultivation genetic algorithm (NCGA) was employed to select optimal factors. The findings revealed the optimal values of the CAP, GAP, and SV were 6, 5, and 4, respectively. Moreover, the ED and HE were decreased by 16.78% and 28.68%, while the MRR was enhanced by 89.72%, respectively, as compared to the common setting values. The explored outcome can be employed as a technical solution to enhance the energy efficiency, drilled quality, and productivity of the EDD operation.
