In order to improve the uniformity of the flow field, the processing stability, and the machining accuracy of the electrochemical machining (ECM) of cross groove structure, in this work, the flow field simulation model of the ECM of cross groove was established, and a flow field analysis was carried out based on the cathodes with different holes. Further, an experimental device was designed for the ECM of the cross groove. The results show that the uniformity of the flow field in the machining gap can be improved by adopting the symmetrical and uniform placement of the cathode hole, and the design of the connecting groove at the outlet of the cathode. In the ECM experiment, the reasonable selection of processing parameters such as the cathode feed velocity and the machining voltage can effectively improve the process stability and machining accuracy. When the diameter of the cathode hole is smaller, the cross groove with better machining effect can be obtained.

为提高十字槽结构电化学加工（ECM）流场的均匀性、加工稳定性和加工精度，本文建立了十字槽ECM的流场仿真模型，基于具有不同孔的阴极进行流场分析。此外，还针对十字槽的ECM设计了实验装置。结果表明，采用阴极孔的对称均匀布置，以及阴极出口连接槽的设计，可以提高加工间隙中流场的均匀性。在 ECM 实验中，合理选择阴极进给速度、加工电压等加工参数，可有效提高加工稳定性和加工精度。当阴极孔的直径较小时，可以获得加工效果较好的十字槽。
