Description
Summary: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.
