Study on Microstructure of the Inner Wall Surface in Samll Hole by Electrochemical Machining with Low-frequency Vibration

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.
