Information integration is an important issue in supporting integrated and concurrent PD. This chapter explores the definition and the structure of an information framework for rapid development of sheet metal parts. This framework aims to build an information bridge to fill the gap among sheet metal part design, process planning and manufacturing systems. It is based on the principles of zero thickness and zero bend radius, which are used to abstract the geometry entities of sheet metal parts in order to facilitate part modelling and information modelling. In this chapter, a tree-based step-structure information modelling methodology for sheet metal parts is proposed and a case study is given.
