Abstract:
-
Conceptual process planning is a key activity for designers to
evaluate manufacturability and manufacturing cost and time in the early
product development stage. Since major manufacturing cost is determined
in early design, it is critical to be able to assess manufacturability and cost
as early as possible in the design process. The integration between process
planning and design is critical to enable these analyses. A literature
review of the current status of Computer-Aided Design (CAD) and
Computer-Aided Process Planning (CAPP) software technologies
reveals the lack of interface standards to enable the integration of
these systems. In order to develop interface standards, information
models have to be first developed to define the interfaces. An initial
information model for conceptual process planning has been
developed. This model includes an activity model and an object
model for manufacturing process selection, resource selection, and
cost and time estimation. The activity model sets the context in
which the objects are used for information sharing and exchange.
The object model defines classes used in conceptual process
planning. The main purpose of developing this model is to initiate the
development of standard interface specifications that are necessary
for design and process planning integration.
