A study on the Ultra precision ECM for Dynamic bearing
Dynamic Bearing의 초정밀 ECM 가공 특성에 관한 연구
Abstract
In this paper a mathematical model, the results of computer simulation and exprimental investigations of electrochemical machining with a too-electrode are presented. The experimental investigations were carried out in order to evaluate the influence of working voltage, initial interelectrode gap size, and metal remove rate. Accuracy of computer simulation evaluated by differences between results of experimental test and computer simulation depends on electrochemical machining coefficient, total overpotential of electrode process, current density, electrical conductivity of electrolyte, and etc. Metal removal rate would be predicted by the simulation of ECM process.
