Modeling and Experiment of Anodic Smoothening in Electrochemical Finishing Based on Lateral Direction Dissolution

From the viewpoint of the change of the anodic surface microtopography in the process of Electrochemical Finishing (ECF), this paper studies the anodic smoothening mechanism of ECF and puts forward the directional issue of the dissolution of anodic surface in the microtopography sense. On condition that the anodic material is dissolved along with the normal direction of the micro-profile on the anodic surface, the influence of wave length of the micro-profile on the smoothening effect is discussed in detail and the mathematical model based on the “lateral direction dissolution” is established. Finally, ECP is taken as the example and the experiment is carried out, the result shows that the smoothening rule obtained by experiment accords with that by calculation.
