Abstract: | Sharing of information is an important issue in supporting integrated and rapid product development. The use of information
modelling technology is a promising approach for solving the problems of the intensive sharing of information in a concurrent
and rapid product development cycle. This paper explores the definition and the structure of a framework of information modelling
for the concurrent design and manufacturing of sheet metal parts. This framework aims to build an information bridge to fill
the gap between the sheet metal part design and manufacturing systems. It is based on abstract handling principles of entities
called zero thickness and zero bend radius principles. Based on this framework, information models can be built for information
sharing by different systems. Knowledge bases that support intelligent concurrent design and manufacturing can also be created.
In this paper, a two-branch tree based stepping-structure information modelling methodology for sheet metal parts is described,
and a case study is given. |
