Aiming at the transformation requirements of aviation enterprises on new and intellectualized production mode in the future

and the production status of ‘multi variety and small batch’

the design of the manufacturing knowledge system

that based on Group Technology is studied. The development frame is proposed

including types

character definitions

character codes

logical relations of characters of parts

and standardization of basic process

applied logic of system

the operational frame of system. The development of the system would not only provide the standardized datum and knowledge of basic process for the transformation of production mode in the future

but also boost the efficiency of process design of aviation parts.
