Abstract：Assembly hole processing features are basic and important for the off-line programming system of aircraft
automated assembly. In order to solve the problem of information source of assembly hole processing features, the characteristics
of feature technology and the model-based definition (MBD) technology in digital assembly are illustrated. Then,
a quickly adding technology for the assembly hole processing features is proposed, in which MBD technology and feature
technology is integrated. After that, the modeling characteristics of the aircraft skin product are represented. With the MBD
model as basic unit, an information model of the product processing features is constructed by processing features in which
geometry and process information of the model is combined. To realize the quickly adding technology on product analog,
the function module of information adding on DELMIA V5 has been developed for CAD digital models. Finally, the information
model of the product processing features is established. The model provides good data source for aircraft automated
assembly off-line programming system and realizes the CAD/CAM/CAPP system integration and data sharing.
