Abstract: Representation of assembly relations of products has a large impact on the strategy of computer-aided assembly planning and its efficiency. Directional assembly connection graph is proposed to represent mating relations of parts in a given product. This kind of graph can embed the processing information of modeling assemblies in directional edges of a graph, and then provide enough information for assembly sequence planning by directional cut set analysis. Directional assembly connection graph is constructed by transforming the process of assembly modeling into the directional graph. After proving the properties of directional assembly connection graph, the algorithm of building the connection graph on the platform of Unigraphics is given.

Key words: connection graph of assembly, directional assembly connection graph, assembly planning
