Artificial intelligence and knowledge based engineering technologies are widely used in die & mould design. In this paper an intelligent deep-drawing process design system for complex circular shells is developed, which build the product representation based on shape element and the knowledge base by machine learning technology. It helps the engineers design the deep-drawing product easier, faster and efficient. A design case is given to illustrate its efficiency.
