The pattern of camber die-drawing are optimized. The physical innate character of drawing with camber die is analyzed thoroughly. For the first time, the periodical relation between the limit drawing coefficient and the large longitudinal stress in dangerous section is established. Furthermore, the rationale to judge limit deforming degree is developed. Then, the limit drawing coefficient of drawing with camber die is proposed. Based on the criterion that the large stress in flange is smaller than that of limit value, the formula of drawing with camber die without wrinkles is deduced.

Besides expressing design result, it provides domain constraint for design process and model information for digital assembly sequence planning and simulation of stamping die, which is usually ignored in the former product models. Taking the specific structure and design process of stamping die into account, the information of workpiece is composed in die product model as product feature. Former product models merely contain mainly about the die design result, this model extends the contents of product model with the relation feature of the composed subassembly and parts and also other associated production knowledge. It is convenient for getting the associated information during intelligentized design process.
