- Abstract. The aircraft assembly process mainly refers to the drilling and riveting/joint process of the aircraft product/components. To ensure the safety of the aerospace vehicle, it's necessary to assemble the aircraft with high accuracy. In this research, factor affecting aircraft assembly accuracy is discussed. And the efficient process is demonstrated to improve the aircraft component's assembly accuracy based on experts’ knowledge information. At first, the assembly accuracy requirements of different aircraft components assembly are provided. According to the required accuracy of aircraft assembly, finishing the drilling and riveting/joint operation is not easy at all. Because various factors affect the aircraft components assembly and manufacture processes such as the transmission dimension and geometry errors. The accumulation of transmission errors will cause various inconsistencies. These inconsistencies are ultimately manifested as component shapes inconsistencies and component joint inconsistencies. This article points out the precaution, awareness, and effective process of the aircraft component adjustment in the jig, to avoid surface failure due to excessive clamping force, drilling, and riveting process. Then summarizes the aircraft components adjustment, clamping, drilling, and riveting processing methods during aircraft components assembly and manufacturing. Finally, these methods have been applied in the finishing of aircraft parts assembly, which represents an efficient assembly finishing of the aircraft components. Keywords: Aircraft Assembly Process, Adjustment of Aircraft Components, Interchange Coordination, Surface Failure, Drilling and Joint.
