“…The connection strength between the coating and the substrate depends on the material and surface morphology of the substrate (Lyubimov et al, 2017). The thickness of the plating is generally controlled by reaction time (Liu et al, 2021a). Zhu et al (2011) have plated the nickel layer on the abrasive tool used for the M-ECM process.…”

Micro hole is the fundamental feature found in any device/components. Hence this paper aims to produces the micro holes using electrochemical micromachining (EMM). The existing machining techniques in EMM for creating micro holes are associated with more overcut (OC). Hence, it is very essential to reduce OC and enhance the machining rate (MR). This paper aspires to investigate the effect of graphite electrode with magnetic force on copper plate. Four different tools namely electromagnetic graphite tool (EMGT), permanent magnet graphite tool (PMGT), graphite tool and stainless steel (SS) tool are employed for these experiments. The major influencing factors are machining voltage in volts, duty cycle in % and electrolyte concentration in g/l was considered on MR and OC. The results exposed that EMGT, PMGT and graphite electrodes produce MR of 106.4%, 74.6 % and 44.5 % over SS tool at parameter level of 23 g/l, 15 V, and 85% respectively. Graphite and EMGT electrode resulting in 11.9% and 3.41 % reduced OC respectively than SS tool at parameter level of 8V, 95% and 28 g/l. Additionally, scanning electron microscope (SEM) picture examination is conducted to identify the magnetic field effect on the work surface.

“…Shenyang University of Aeronautics and Astronautics used a neutral salt solution electrolyte to machine a deep small hole with a diameter of 600 um and a depth of 12 mm using a tube electrode after casing insulation [9]. Minghao Jia et al used a full cone pulling method to design a cathode structure for electrolytic processing of large deep-diameter-ratio shaped holes to achieve uniform flow field division and successfully overcome the key technical problems of electrolytic processing of small-sized shaped holes [10]. Xue Runrong et al, based on the principle of electrolytic processing, designed the inflow structure, proposed measures to improve the stability and processing accuracy of the e lectrolytic processing of shaped holes, and the study showed the reasonable processing parameters in the composite processing mode, its effect on the shaped hole forming pattern, and formulated a practical processing of large deep-diameter ratio shaped holes [11].…”

For parts with large deep-diameter ratio shaped hole features, the complex structure of the profile and large deep-diameter ratio led to poor profile machining accuracy. The shaped hole processing requires high efficiency, high precision and low cost. Therefore, it is difficult to use the traditional processing method, and the electrolysis method based on the anodic dissolution mechanism is adopted, which has no shear stress and accurate profile forming. The 3D model is established based on the part, and the cathode and tooling structure is designed. Based on COMSOL software, we designed the flow channel uniformity of electrolytic processing of shaped holes and analyzed the arrangement of cathode outlet holes in electrolytic processing, which affects the uniformity of the processed surface and flow field. The arrangement of cathode exits holes to meet the uniform distribution of electrolyte at the surface boundary and high-speed flow at the surface was obtained by simulation analysis. By analyzing the flow field of different inlets, the flow rate magnitude of the shaped boundary and surface of the surface shaped hole is positively correlated with the inlet pressure of the electrode liquid.
