Aircraft manufacturing coordination route is an important process file
which connects the interchangeable coordination scheme designing with tolerance distribution. The digital design of aircraft manufacturing coordination route has important significance for computer aided tolerance design and the implementation of aircraft digital process. First
we classify the design knowledge of aircraft manufacturing coordination route and build the knowledge representation model and use the knowledge by reasoning technology. Then
we create figures library of manufacturing coordination units and design manufacturing coordination route interactively using intelligence capturing technology. Finally
the information model of aircraft manufacturing coordination route is designed and coordination process files for the standardization of the tolerance allocation are generated automatically
which provide support for the computer aided tolerance design.
