Research on the Flow Field of Electrolytic Processing for Shaped Holes with Large Depth-to-diameter Ratio

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