Multiphysics Numerical Simulation of the Transient Process in Electrochemical Machining

To fully understand the electrochemical machin-ing profile, a multi-physics coupling simulation model including flow-electric-temperature-structure field were established to analyze the corrosion process of the anode material and the change trend of temperature, hydrogen volume fraction, electrolyte conductivity and current densi-ty in the processing gap. The analysis results show that the temperature and hydrogen content gradually increase along the process direction. The current density and material re-moval showed a parabolic trend of the upper opening and the lower opening, respectively. The simulation of the dif-ferent physical field changes in the electrochemical ma-chining blade profile can not only better understand the complex physical phenomena in the machining, but also provide a theoretical basis for the selection of actual elec-trochemical machining parameters.
