提高闭式整体构件气流通道数控电解/电火花组合加工效率的关键是提高其粗加工工序电解加工的效率，可尝试采用开槽、拷形一次完成的方案。由于气流通道深、窄、弯曲，首先必须面对的是电解加工间隙流场分布极不均匀的问题，通过改变阴极结构、回液孔分布及供液方式的设计，基于COMSOL对上述不同阴极进行电解加工间隙流场的仿真、比较，改善了间隙流场分布。分析表明，当进口压力为0.8 MPa，十字交叉槽槽宽为1.5 mm，锥头回液孔数量为12个，三排错开排放，间隙流场较均匀。

The key to enhance the process efficiency of an organic combination of ECM-EDM for machining the airflow channel of closed integral structure is to shorten the working hours of ECM as a rough machining step. The scheme of diging groove with shaping simultaneously was proposed. The airflow channel of the closed integral structure is so deep,narrow and winding,that the first thing we have to face with was the asymmetry distributing of flow field in machining gap. In order to improve the flow field,the emulation for flow field based on COMSOL was processed in the light of which its cathode structure was recomposed and the sizes of holes were amended. The result of the simulation shows that the flow field in machining gap is relatively uniform in condition of that the inlet pressure is 0.8 MPa,of that the cross groove width is 1.5 mm and the hole number is 12 with three rows of stagger distribution.
