摘要
A new machining approach was proposed using electrolyte film to support the floating cathodes to form the machining inter-electrode gaps, whose regulation and control were realized by adjusting the flows and currents. Taking ECM of floating cathodes with round mouths as an example, a mathematic model of the machining gaps was established on the basis of fluid mechanics and electrode process kinetic theory, and the relationships among gaps, flows, pressure differences and currents were acquired. By analyzing characteristics of the gap flow fields using the software Fluent, the distributions of pressure fields and velocity fields of the electrolyte in the gaps were established, and pressure differences between the inlets and outlets, and the flow rates of the outlets were obtained. Additionally, different machining gaps under dissimilar flow and current circumstances were acquired by experiments. The results and variation characteristics of the theoretical model and the experiments are similar to each other. © 2017, China Mechanical Engineering Magazine Office. All right reserved.
