摘要
以轴承内环外表面为光整加工对象,建立了脉冲电化学光整加工中理想光滑表面及实际尖峰状表面数学模型,分析了极间间隙、电流密度、光整时间等因素对阳极整平效果的影响规律。仿真与实验结果表明,所建模型可以解释整平机理,具有较好的加工质量预测能力,可为光整加工参数的合理选取提供依据。
The surface of the bearing inner raceway was finished by pulse electrochemical finishing （PECF）. A mathematical model was developed and the effects of finishing parameters, such as the interelectrode gap, current density and the finishing time, on the anodic smoothing was analyzed. The results show that predictive results based on the developed mathematical model are in good agreement with the experimental results. The developed model can not only explain the mechanism of anodic smoothing, but also be used as a guideline for accurately choosing finishing parameters.
