Abstract: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.
