摘要
Although deburring technology is used in precision manufacturing and high-quality machining, deburring is still considered a difficult problem. Precision parts require care to achieve precise dimensions and surface quality and in subsequent finishing operations. Deburring and edge finishing typically receive little attention from designers and manufacturing engineers. Due to deburring difficulties, it can account for more than 30% of the total production cost when components are small. Efficient and effective deburring of miniature and/or precision components is very difficult. Therefore, this work applies a highly efficient and fully automatic novel electrochemical system that uses a rotating barrel. The effects of the main factors, such as barrel rotational speed, electrical current density, electrolyte temperature and process time, are investigated. Finally, optimal conditions are identified by applying the design of experiment to the required edge quality. The burrs on brass gears are dissolved and removed properly and the radius of the fillet of the gears after deburring has a small standard deviation of 5.9 mu m within only 5 minutes when using the proposed system of a rotational barrel with electrochemical deburring. This electrochemical system is an effective and efficient system to remove burrs from miniature metal parts.
