Effects of Machining Parameters on Electrochemical Multi-Field Coupling

Electrochemical machining involves three couplings between electric field, flow field and thermal field. The precipitation of hydrogen on the surface cathode will affect entire electrochemical process final quality workpiece. Finite element software is used to analyze effects different voltages, electrolyte inlet pressure interelectrode gap current density, volume fraction, conductivity temperature distribution in this article. research results show that increase processing voltage fraction temperature, decrease solution. As increases, density increase, but decrease. decrease, increases when electrodes increases. At inlet, are relatively large, gradually along direction, while smallest at accumulate reach maximum outlet. Through multi-physics coupling simulation, bubble can be predicted, which provide a theoretical basis for actual parameter selection.
