Abstract
We consider a new approach toward the generation of mechanical assembly sequences with computers. We propose an algorithm to generate the precedence constraints between parts considering the geometric interference during assembly. The precedence constraints are represented by an adjacency matrix. The number of assembly sequences can be estimated by a simple matrix manipulation without actually generating them. This allows designers or process planners to interactively reduce the number of sequences by regarding a subset of parts as a group, and considering other evaluation viewpoints. After the number of the sequences is reduced sufficiently, all feasible assembly sequences are generated based on the evaluation viewpoints selected by designers without a large amount of computation. An example demonstrates the practical efficiency of the proposed method.
