Abstract: This paper summarized the research work progresses of authors in recent years, included: the combined machining technology where the shaping and finishing were realized in one process, the cross scale precision forming technology where the precision and roughness of parts might be improved at the same time and hand-held tool finishing technology for free curved surface parts by which the surface topography might be improved under the conditions of ensurence of the precision of parts. The study results indicate that, by optimizing the process system structure and parameters of electrochemical mechanical machining, the accuracy and surface topography may be improved for those parts with regular surface like gears and bearings etc, and surface topography may be improved on conditions that the precision is guaranteed for those parts with irregular surfaces.

Key words: electrochemical machining, electrochemical mechanical machining, finishing, precision machining
