“…Abrasive-assisted Jet-ECM is a hybrid process that takes inspiration from water jet cutting, by adding abrasive particles to the jet of electrolyte. The aim of the hybrid process is to combine mechanical abrasion of the workpiece surface and passive layers with the electrochemical process for combined material removal mechanisms [49,50].…”

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.

“…The measured data of aspect ratio and roughness for the micro pits from Figure 7a-p are listed in Table 3 (No. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. It can be seen that the micro pit size and surface morphology processed by AS-EMM vary greatly under different experimental parameters.…”

“…It is widely used in the machining of microstructures due to its high localization, large aspect ratio of machining morphology, and having no special requirements on tool shape. Liu et al [11] investigated abrasive composite EJM by adding a solid micro-abrasive into the electrolyte. The anode dissolution and micro-abrasive erosion worked together to remove materials and improve the surface texture processing efficiency.…”

Microstructures on metal surfaces with diameters of tens to hundreds of micrometers and depths of several micrometers to tens of micrometers can improve the performance of engineering parts. Air-shielding electrochemical micromachining (AS-EMM) is a promising method for fabricating these microstructures, owing to its advantage of high efficient and better localization. However, the machining performance is often influenced by the machining or nonmachining parameters in AS-EMM. In order to get a better machining result in AS-EMM, the optimization of AS-EMM, including nozzle inclination and process parameters, was studied in this paper. Firstly, nozzle inclination was optimized by the different selected air incidence angles (θ) in simulation, and θ = π/4 was advised. Then, the grey relational analysis based on the orthogonal test method was used to analyze the grey relational grade for parameters and obtain the optimal parameter combination, i.e., at electrolyte velocity 5.5 m/s, gas velocity 160 m/s, and voltage 8 V. Finally, the optimization result was verified experimentally.

“…This serves to normalise the effective current density outside of the central machining region to reduce overcut. Electrochemical slurry-jet machining [42,43] was developed, whereby the anodic dissolution mechanism is complemented by the application of abrasive jet, again increasing the material removal rate leading to higher aspect ratio holes, although at the loss of surface quality. A further adaptation is the introduction of a pulsed current power supply.…”

a b s t r a c tElectrochemical jet processing techniques provide an efficient method for large area surface structuring and micro-milling, where the metallurgy of the near-surface is assured and not adversely affected by thermal loading. Here, doped electrolytes are specifically developed for jet techniques to exploit the Gaussian energy distribution as found in energy beam processes. This allows up to 26% reduction in dissolution kerf and enhancements of the defined precision metric of up to 284% when compared to standard electrolytes. This is achieved through the filtering of low energy at discrete points within the energy distribution curve. Two fundamental mechanisms of current filtering and refresh rate are proposed and investigated in order to underpin the performance enhancements found using this methodology. This study aims to demonstrate that a step change in process fidelity and flexibility can be achieved through optimisation of the electrochemistry specific to jet processes.
