Study on Electrochemical Mechanical Precision Finishing Technology

介绍了该研究组近年来在电化学机械精准光整加工技术研究方面的工作进展情况,包括:光整过程中同时完成形状成形的光整与成形复合加工技术;同时改善零件精密度和表面形貌的跨尺度精确成形加工技术;保证精密度条件下改善表面形貌的自由曲面零件手持式工具光整加工技术。研究工作表明:通过合理优化电化学机械加工工艺系统结构和参数,对于齿轮、轴承等规则表面零件,可以实现同时改善零件精度和表面几何形貌;对于非规则表面零件,可以在保证零件精密度条件下改善零件表面几何形貌。

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.
