摘要：Man-hour ration is an important work in process planning, it influences on the production cost and production plan. According to the practical requirements of rotary bearing manufacturing enterprise, a function framework of man-hour ration management system is proposed in the paper. Some key techniques are discussed, involving UML modeling, man-hour calculation method based on the general procedure, automatic generation and print of man-hour report. On this basis, a man-hour ration management system of rotary bearing is developed by using object-oriented programming method and SQL Sever database technology. Finally, an application case is given, which is easy to operate, and the man-hour calculation is fast and accurate, the generated man-hour report is unified and standardize.
