Research on generation of three-dimensional surface with micro-electrolyte jet machining

A review of physical experimental research in jet electrochemical machining

“…Unlike Ippolito et al [2], Natsu et al [10] found that altering the gap width did have an effect on the machined profile diameter. To predict the machined profile from superimposed paths, a function of machined depth was calculated from a sample experiment in which a pit was machined with known parameters.…”

“…Natsu and Kunieda performed two investigations into producing complex surfaces [1] and three-dimensional surfaces using Jet-ECM [10]. The work built upon investigations in the 1990s in which Yoneda and Kunieda studied the electric potential distribution and the current density distribution in the electrolyte flow and workpiece ( Fig.…”

“…From both experiments, it could be seen that using superimposed paths could produce complex shapes, with an 8% error on calculated expectations. However, optimising the parameters in each machining interval reduces this error [10]. Other findings include:…”

Mirror-like finishing by electrolyte jet machining

“…By translating the jet over the workpiece, intricate patterns can be fabricated without the use of a special mask [3]. Even threedimensional shapes can be machined by controlling the current and dwelling time of the jet over the workpiece [4,5]. Use of a focused laser beam directed into the jet stream was found to further enhance the material removal rate [6,7].…”

Electrochemical micromachining using flat electrolyte jet

“…This process can be used not only for removing processes by anodic dissolution, but also for coloring process by anodic oxidation [8]. Even three-dimensional (3D) shapes can be machined by controlling the current and dwelling time of the jet over the workpiece [9]. Furthermore, by reversing the polarity, selective electroplating [10] and 3D additive manufacturing [11] can be performed.…”
