| 摘 要： | 本文提出了一种新颖的电极,即模板电极,同时对模板电极电解加工成型规律进行了研究.首先建立了反映实际加工过程的数学模型,并考虑非线性电解液的影响,利用参数化有限元分析技术对其蚀除过程进行模拟和数值求解,同时进行了相应的试验验证,试验结果显示,模拟蚀除的深度和直径与实际加工的深度和直径相符. 此工艺实现了以较高的效率在金属薄板上加工出群孔结构,且孔径一致均匀,加工的重复性好.

| Abstract: | In the paper, a novel electrode called mask electrode is advanced to machining micro matrix-hole in electrochemical machining. Passivating electrolyte is taken into account. A mathematical model is presented to illustrate how the machined profile evolves as time elapses. Its numerical analysis and the results of experiment show the actual machining process accords well with mathematical model. The micro matrix-hole structure was efficiently prepared with good accuracy. |
