Abstract: As the method of control of interchange and coordination with analog quantity transfer cannot satisfy the needs of modern aircraft development, a new way of control of interchange and coordination with digital quantity transfer becomes the foundation of digital aircraft assembly. This article studies issues for the assembly of a given aircraft door frame taking into consideration the characteristics of digital aircraft manufacture. Firstly, an analysis of the structure of the door frame is accomplished and all the data with interchange and coordination are collected. Secondly, the digital technology standard model and the main data are defined, and then the flowchart of digital assembly interchange and coordination for the door frame is created. Thirdly, based on these characteristics, the techniques for establishing a model of interchange and coordination are introduced and developed in detail. Finally, the validity of the interchange and coordination method of digital assembly for the door frame is demonstrated and issues for future development are proposed.

Key words: aircraft assembly, process planning, digital manufacturing, data model, aircraft structure
