“…The use of laser assistance tends to improve the conductivity in electrolyte and material and localisation of the reaction at the risk of electrolyte boiling [41]. It was in agreement throughout the studies that laser assistance increases the material removal rate compared with standard Jet-ECM [38,39,41,42], especially at lower currents and electrolyte concentrations [6] as well as improving hole taper [6,38,39,42]. The effect on roughness was material dependant [6] and in some cases, the laser assistance caused a larger overcut [6].…”

“…Assisted jet-ECM is the combination of jet-ECM with additional technologies to produce a hybrid system. The aim of these hybrid systems is to improve at least one area of the unwanted machining characteristics in Jet-ECM such as overcutting, stray machining, tapered holes and aiming to improve the performance and capability of the process [37,38].…”

Jet electrochemical machining (Jet-ECM) is a non-traditional machining process that has developed rapidly since its introduction in the 1980s with progress being made in micro-machining and surface finishing. This paper critically reviews the development of physical experimental work in Jet-ECM and corresponding hybrid technologies and their applications, e.g. laser-and air-assisted Jet-ECM. In addition to discussing the merits of the physical experimental research, the paper concludes with research challenges in the future of Jet-ECM development.

“…Researchers proposed a technique which uses sinusoidal electrical signals in ECMM that are readily available and further eliminates the use of an expensive ultra-short pulse power source [10]. Laser-assisted jet ECM (JECM) was developed indigenously and its performance was compared with JECM; the experimental outcomes reported that the material removal rate (MRR) increased by 29.16% and the taper angle abated by 48.43% [11]. Magnetic field-assisted ECM is a process, where the magnetic line is orthogonal to the electrolyte stream path firming up the mass transfer rate and effectively reducing stray corrosion, thus there is no deterioration in the electrolytic processing flow field which resulted in improved surface roughness of the workpiece [12].…”

An attempt has been made to study the influence of magnetic field on the micro hole machining of Ti-6Al-4V titanium alloy using electrochemical micromachining (ECMM) process. The presence of magneto hydro dynamics (MHD) is accomplished with the aid of external magnetic field (neodymium magnets) in order to improve the machining accuracy and the performance characteristics of ECMM. Close to ideal solution for magnetic and nonmagnetic field ECMM process, the parameters used are as follows: concentration electrolyte of 15 g/l; peak current of 1.35 A; pulse on time of 400 s; and duty factor of 0.5. An improvement of 11.91–52.43% and 23.51–129.68% in material removal rate (MRR) and 6.03–21.47% and 18.32–33.09% in overcut (OC) is observed in ECMM of titanium alloy under the influence of attraction and repulsion magnetic field, respectively, in correlation with nonmagnetic field ECMM process. A 55.34% surface roughness factor reduction is ascertained in the hole profile in magnetic field-ECMM in correlation with electrochemical machined titanium alloy under nonmagnetic field environment. No machining related stress is induced in the titanium alloy, even though environment of electrochemical machining process has been enhanced with the presence of magnetic field. A slight surge in the compressive residual factor, aids in surge of passivation potential of titanium alloy, resulting in higher resistance to outside environment.

“…Laser-assisted jet electrochemical machining (LAJECM) is a hybrid machining process (Pajak et al , 2004a). In this process, the predominant mechanism of material removal is electrolytic dissolution is the same as that of Electrochemical Machining (ECM) (Pajak et al , 2006), but the dissolution is aided by the thermal energy of a low power laser beam (Malik and Manna, 2018a). LAJECM has a low power laser beam aligned coaxially with the electrolytic jet to form an effective non-contact electrode (cathode) and directed towards the workpiece (anode) surface (Malik and Manna, 2018b).…”

Purpose The purpose of this paper is to optimize the laser-assisted jet electrochemical machining parameters, namely, supply voltage, inter-electrode gap, duty cycle and electrolyte concentration during machining of WC-Co composite using grey relational analysis and fuzzy logic. Design/methodology/approach In this work, experiments were carried out as per the Taguchi methodology and an L16 orthogonal array was used to study the influence of various combinations of process parameters on material removal rate, hole taper angle and surface roughness height. As a dynamic approach, the multiple response optimization was carried out using grey relational analysis and fuzzy logic. Findings The process parameters were optimized using grey relational analysis and fuzzy logic for different machining conditions such as balanced manufacturing, high-speed manufacturing and high-quality manufacturing. The research documented in this paper can be scaled up for case studies regarding industrial applications to compare optimization methods for manufacturing processes that are already being carried out. Originality/value An attempt to optimize material removal rate, hole taper angle and surface roughness height together by a combined approach of grey relational analysis and fuzzy logic has not been previously done.
