Abstract：

The paper builds(?)up the product design models using information modelling based on fea- tures,and discusses the definition and automatic extracting of manufacturable features for sheet metal bendings.Then,the decision knowledge and rules about bending sequences layout have been summarized.On the basis of these,the automatic process planning system for sheet metal bending has been developed.It builds the connection between CAD and CAM.
