摘要
工具阴极设计是航空发动机叶片电解加工工艺过程中的关键环节。本文采用有限元数值算法求解加工间隙内的电场分布,考虑非线性电解液对成型规律的影响,进行叶片的阴极设计计算。对加工间隙分布的分析表明,将非线性电解液的影响带入阴极求解中,能使所研究的问题更接近实际情况,从而能提高阴极设计的精度。
Electrochemical Machining （ECM） is widely used in the manufacturing of aero-engine blades because of its several advantages, in the process of which tool design is an important step, but the design method used in the ECM of aero-engine blades usually show unsatisfactory accuracy. Based on finite element, the design method used in this paper starts with 3D modeling of blades, analyses the inter-eleetrode gap distribution and considers the influence of electric current efficiency brought by passivating electrolyte. Comparison results show that the tool cathode designed with passivating electrolyte fits the shaping of anode blades and improves the accuracy of tool design.
