Abstract:

In this paper,first,template cathode is applied to the electrochemical machining of matrix-hole,and the corresponding shaping law is investigated.Next,a mathematical model to describe the actual machining process is established.Then,by considering the effects of nonlinear electrolyte,the parametric finite element method is adopted to simulate and numerically analyze the erosion process.Finally,some experiments are performed to verify the proposed model.The results indicate that the simulated erosion depth and diameter accord well with the actual ones,that the two-side electrochemical machining with template cathode helps to reduce the taper of the matrix-hole and shorten the machining time,and that the electrochemical machining with template cathode helps to obtain matrix-hole on metal sheet with low cost and high efficiency

Key words: electrochemical machining, electric field, finite element, shaping law
