电解加工（ECM）中的表面形成机制尚未完全理解，因为在电极间的间隙中可能发生复杂的非均相反应。对流动现象的全面了解可以提供这方面的大量信息。本文提出的表面轮廓的定性和定量分析突出了表面形成的流速的显着影响。流速显着影响短波长的不规则性的表面产生的阳极平滑。在较低的速度下，工件晶粒尺寸也影响表面光洁度。当雷诺数低于10，000时，较小的晶粒产生较好的光洁度。阴极再现性随着速度的增加而变差，但发现总体光洁度良好。短波长的不规则性存在于再现的配置文件中大大减少与增加流速。当工具的放置方向与流动方向交叉时，可以看到更好的再现效果。这些研究对于理解阳极平滑和阴极再现具有重要意义，并且这些实验结果补充了该领域的理论模型。
The mechanism of surface formation in electrochemical machining (ECM) is not fully understood because of the complex heterogenous reactions possible in the inter-electrode gap. A complete understanding of the flow phenomenon can provide considerable information in this regard. Qualitative and quantitative analyses of surface profiles presented in this paper highlight the significant effect of the flow velocity on surface formation. The flow velocity significantly affects the short wavelength irregularities of the surfaces produced in anodic smoothing. At lower velocities, the workpiece grain size also influences the surface finish. The smaller grains yield better finish when the Reynolds number is below 10,000. The cathode reproduction is poor with increasing velocity but the overall finish is found to be good. Short wavelength irregularities present in the reproduced profiles reduce considerably with increasing flow velocity. Better reproduction is seen when the lay of the tool is across the flow. Such studies are significant in understanding the anodic smoothing and cathode reproduction, and these experimental results augment the theoretical models developed in this field.
