【摘要】 杂散腐蚀是影响整体叶盘型面精密电解加工精度的重要因素，辅助阳极可以有效抑制相邻已加工叶片的杂散腐蚀，进而提高叶片加工精度。针对中小型航空发动机整体叶盘叶间通道狭窄扭曲导致辅助阳极设计困难的问题，提出了一种辅助阳极结构设计方法，该方法通过优化工具阴极进给路径实现了辅助阳极的优化设计。试验结果表明，采用该方法设计的辅助阳极在开展整体叶盘电解加工试验时，阴极组件可以顺利进给至加工起始位置，加工后叶片表面光滑，无明显杂散腐蚀痕迹，有效提高了整体叶盘的加工精度。更多还原

【Abstract】 Stray corrosion is an important factor affecting the precision electrolytic machining(PECM) accuracy of the blisk surface, and the auxiliary anode can effectively inhibit the stray corrosion of adjacent machined blades, thereby improving the machining accuracy of blades. In order to solve the problem that the narrow and twisted inter-blade channel of the blisk of small and medium-sized aero-engines leads to the difficulty of auxiliary anode design, an auxiliary anode structure design method was proposed, which realized the optimal design of the auxiliary anode by optimizing the feed path of the tool cathode. Results of the experiment research show that the auxiliary anode designed by this method can be fed to the starting position of the machining smoothly, and the surface of the machined blade is smooth, and there are no obvious traces of stray corrosion, which effectively improves the machining accuracy of the blisk.更多还原
