摘要：
Considering the effects of bubbles on processing precisions, a gas-liquid two-phase flow field in ECM processes was described according to the Euler-Euler two-fluid model. Coupling with the electric field and the temperature field, the distributional regularities of the cathode and anode surface bubble rate, temperature, electrical conductivity and current density were analyzed. The simulation optimizations of the anode surface bubble rate and current density were researched by adjusting voltages, inlet pressures and outlet pressures. The simulation results show that reducing machining voltages and increasing the outlet pressures may improve the electrical conductivity distributions and make the current density distribution on the anode surfaces more uniform, under the same flow rate. The experimental results show that the distributions of the current density on the anode surfaces are consistent with the height error distributions of the workpieces. The precisions of the workpieces are improved by optimizing the parameters. © 2019, China Mechanical Engineering Magazine Office. All right reserved.
