The purpose of this study is to implement a search system to improve the coupling efficiency of precision fasteners that require strict control. Currently, mainstream systems in aircraft manufacturing do not consider the work process or environment. In existing databases, only data on fasteners is viewable; it is inefficient because information such as bore diameter and the required tool manufacturing process is maintained separately. Also, the torque required when fastening a fastener is needed so the system can retrieve data quickly. In this study, we have designed a system that can search for various fastener information efficiently. Also, by implementing an alternative fastener system to calculate the similarity between the fasteners, we can improve the convenience of selecting a replacement fastener in the design department. In this paper, this system is shown to significantly reduce the cost of acquiring information on fasteners, and to provide some degree of benefit in terms of production cost.
