Actual rapid development needs of domestic and foreign modern civil aircraft are described. Referencing experience of foreign aviation manufacturing enterprises and domestic aircraft sheet metal progress

overall methods and ways of rapid sheet metal process design system are built

and taking knowledge engineering technology as the core

numerical reasoning as means. Rapid sheet metal design process system is established by expert knowledge building and system software development. Process analysis and design of sheet metal parts are realized in bulk and automatically; Process analysis reports

manufacturing outline

NC code are automatically generated

which can greatly increase process design efficiency of civil aircraft development and reduce labor.
