Feature-based design modification in co-assembly design

Abstract

This paper discusses the feature-based design modification in a collaborative assembly (co-assembly) design environment. A hierarchical co-assembly representation model has been proposed and a proposed assembly feature design scheme has been given to resolve the co- assembly design issue. In order to realize the design modification propagation control, an XML schema was developed to transfer the assembly design information by defining each feature using the XML format based on the co-assembly representation model proposed. The detailed design modification propagation control mechanism has been demonstrated through an example case study. Furthermore, a system framework suitable for realizing the co-assembly design modification is also proposed and developed.
