An Information Modeling Approach in Conceptual Design for Cooperative Design
Information modeling is critical to the integration ofconceptual design and process planning. Aninformation model for conceptual design is provided inthis paper. Conceptual design is a key activity in earlyproduct development. It determines product functions,form, and the basic structure. Since majormanufacturing cost is determined in early design, it iscritical to be able to assess manufacturability and costas early as possible in the design process. A literaturereview of the current status of Computer-Aided Design(CAD) and Computer-Aided Process Planning (CAPP)software technologies reveals the lack of interfacestandards to enable the integration of these systems. Inorder to develop interface standards, informationmodels have to be first developed to define theinterfaces. An initial information model for conceptualprocess planning has been developed.This modelincludes an activity model and an object model formanufacturing process selection, resource selection,and cost and time estimation. The activity model setsthe context in which the objects are used forinformation sharing and exchange. The object modeldefines classes used in conceptual process planning.The main purpose of developing this model is to initiatethe development of standard interface specificationsthat are necessary for design and process planningintegration.
