“…However, use of a bipolar current wears the metallic nozzle, removing one of the major benefits of Jet-ECM. Bisterov et al [17] developed an electrochemical jet processing (EJP)-specific computer-aided manufacturing software with the aim of controlling the Jet-ECM process to produce specifically located micro-scale features. The software allows the definition of process parameters as well as tool path strategy as well as the ability to replicate images in to machined profiles.…”

“…The hybrid technologies outlined in this review also show good promise at early stages of research, but also require a larger amount of understanding to move the technology further towards being a fully understood and controlled technology. More recent studies have shown major improvements to system control and machining precision [4,17,31,32,35] but further developments are still required.…”

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.

“…Utilising the OSPE nozzle and rotational head, features were machined into 0.8 mm thick medical grade stainless steel scalpel blades. Various serrated knife edge designs were developed in CAD and translated via CAM, developed by the authors [12], into toolpaths creating bespoke cutting type features (Figure 4d). All part features were created with 8 successive passes taking a total of ≈ 5 minutes to create each sample.…”

Recent innovations in electrochemical jet processing have caused step changes in process flexibility and precision. However, utilisation of these innovations requires the development of new machine tool technology. Presented here is a new methodology enabling the exploitation of highly customisable energy density profiles regardless of toolpath vector whilst minimising any error from the intent profile. A further approach is defined whereby active tooling allows the energy density profile to be modulated as a function of position within the toolpath, giving rise to dynamic feature creation. Adoption of this methodology allows a new design freedom within electrochemical jet processes.

“…Therefore, Jet-ECM has been highly used by researchers and engineers. Its fundamental theories, key technologies, and potential application development have been well studied [ 40 , 41 , 42 ]. Kawanaka et al [ 39 ] achieved a mirror-like micro-pit structure on a stainless steel workpiece using Jet-ECM with bipolar pulse current.…”

Amorphous alloy (AA) is a high-performance metal material generally with significantly excellent mechanical and corrosion resistance properties and thus is considered as a desirable material selection for micro-scale articles. However, the microfabrication of AA still faces a variety of technical challenges mainly because the materials are too hard to process and easily lose their original properties, although at moderately high temperatures. In this study, jet-electrolyte electrochemical machining (Jet-ECM) was proposed to microfabricate the Zr-based AA because it is a low-temperature material-removal process based on the anode dissolution mechanism. The electrochemical dissolution characteristics and material removal mechanism of AA were investigated, and then the optimal process parameters were achieved based on the evaluation of the surface morphologies, surface roughness, geometrical profile, and machining accuracy of the machined micro-dimples. Finally, the feasibility was further studied by using Jet-ECM to fabricate arrayed micro-dimples using the optimized parameters. It was found that Jet-ECM can successfully microfabricate mirror-like surface AA arrayed precision micro-dimples with significantly high dimensional accuracy and geometrical consistency. Jet-ECM is a promisingly advantageous microfabrication process for the hard-to-machine AA.
