Flow Field Design and Experimental Research of ECM of Array Spherical Groove Structures with Variable Cross-sections.

Variable cross-section spherical groove structure had high surface hardness and complex 3D shape. ECM had better technical and economic advantages, but the processing accuracy and processing stability were affected by the flow field obviously. In order to improve the uniformity of the electrolyte flow field, the influences of the electrolyte flow mode and channel structure on the flow field distribution were discussed based on the flow field simulation analysis, and the ECM experiments were carried out. The simulation and test results show that the zonal liquid flow in directional channel is conducive to improving the stability of the flow field and the consistency of the flow rate distribution, which may improve the processing stability. Optimization of the inlet and outlet flow channel structures may further improve the surface quality of the spherical groove, which may meet the requirements of machining stability and machining accuracy.
