为了研究低频振动电解加工对小孔径内壁面加工的影响，采用数值模拟和实验相结合的方法进行电解加工，分析影响加工结果的工艺参数及低频振动对小孔径内壁面加工精度的影响。结果表明：采用阴极低频振动加工小孔径内壁面，有利于加工间隙内电解液的循环更新和电解产物、电解热的排除，提高加工精度，改善加工定域性，同时也延长了工具电极的寿命。%In order to study the effect on process for small hole of the inner wall surface by low-frequency vibration electrochemical machining (ECM) ,by ECM combinated experiment and numerical simulation,process parameters affectting the processing results and the affect on accuracy of the inner wall surface in small hole by ECM with low-frequency vibration were studied. The results show that the ECM with low-frequency vibration is conducive to exclude electrolysis products ,electrolysis heat and renewal the electrolyte in the machining gap ,improve the accuracy and locality of processing ,but also extend the life of the tool electrode.
