Abstract:

A two-dimensional model of the electric field of three sorts of cathodes built in ANSYS software based on FEM was solved herein. The processing course was computed cumulatively by these several periods dividing the processing course of three sorts of cathodes. The distribution of the electric field of the processing region and the density of the nodes on the surface of the work piece model were obtained and the contour curves of simulation processing at different time were obtained by the position coordination of each node. The experiments were carried out to verify the electrochemical machining parameters based on the simulation. It is showed that with the amended parameters of the simulation it can meet the machining requirements of the fuel injection, which is the basis for electrochemical dressing of the intersection line of the fuel injection. 
