摘要
采用有限元数值算法求解加工间隙中的电场分布,考虑间隙内流场和非线性电解液的影响,对最终的阳极工件型面进行预测。对某型发动机叶片三维复杂曲面进行了预测计算,并与其工艺试验结果进行比较,证明预测模型具有较高的精度。
The finite element method was applied to analyse the electric field distribution in the machining gap under stationary state of electrochemical machining （ECM）. And factors affecting the electric field distribution, such as fluid parameters and passivating electrolyte, were also taken into account. The results of calculation and experiments show that the model determining anode workpiece shape is of high precision. Thus considerable costs and time of experiments are saved and the reliable determination is helpful to design proper cathode tool.
