3D electrochemical machining computer simulations

This paper proposes a general applicable numerical method for the simulation of 3D electrode shape changes obtained during electrochemical machining processes based on the “marker” method. The electrode shape change is found by displacing each node proportional with, and in the direction of the local current density according to Faraday’s law. The local growth rate is obtained by numerically solving the potential model using the boundary element method. Results related to 3D electrochemical machining of the letter “E” are presented.
