The pulse supply design scheme of which the pulse frequency and width curve are automatically set during machining process were proposed. This method can automatically regulate pulse parameters according to the removing amount. The power supply outputs big duty ratio pulse in the early processing,which can significantly improve the material removal rate. In later period,the output small duty ratio pulse can effectively improve the working accuracy and surface quality. The power supply not only enhances the electrochemical machining efficiency ,but also improves the processing precision and surface quality.
