Abstract: The application of the high frequency group pulse electrochemical machining (HGPECM)
in micro-manufacture is presented. It is introduced that how the group
pulse is produced, the influence of the reversed current and pressure wave on the machining quality and the principle to design the cathode in the micro-manufacture. Based on the designed moulds of facet and ultrathin structure part, the experiment of the high frequency group pulse electrochemical machining is carried out. It is indicated that high machining quality can be obtained and HGPECM can be used in the micro-manufacture.
Key words: Micro-manufacture High frequency group pulse Electrochemical machining Machining quality
