The shortest-path spanning tree of assembly dimension and its application

The purpose of this paper is to obtain the reasonable dimensioning for each part and a full-dimension model of assembly dimensions.,The relational path graph of assembly dimension, the shortest-path spanning tree of functional dimension and a revised spanning tree are established in this paper.,The proposed method can obtain reasonable dimensioning of parts and establishment of dimension model in an assembly.,The proposed method can easily realise by computer and be more suitable to automatic dimensioning and establishment of dimension model of parts.
