Abstract: A new method of addendum and binder surface design is proposed. Using this method, the design of addendum surface and binder surface is completed in CAE preprocessor instead of in CAD systems as ordinary methods do. It improves the efficiency of the tool design. After the design is completed, it can automatically produce a clean and connected mesh. This method provides convenient way to model true drawbead and improve the simulation’s precision. Many applications have proved this method is suitable for automotive engineering.
