Abstract: Unique definition and classification of assembly feature are presented. Assembly feature|s definition is provided using the concept of assembly intents. Assembly features classification is done based on useful assembly-specific information. Assembly features provide information that result in a smaller number of assembly sequences that have to be checked in assembly sequence optimisation. Due to the reduction in assembly sequences, AND/OR graph not only reduces considerably but also becomes very simple. This can result in a significant reduction in the computation time for assembly sequence planning. Real-life examples are given to demonstrate how assembly features are useful in sequence planning.

Keywords: assembly features; assembly intents; precedence relationship; feature classification; ASP; assembly sequences; sequence planning; AND/OR graph.
