Research on surface filling for stamping simulation of automobile panels

In Stamping simulation of automobile panels, generation of addendum and binder is a very important step in die-face engineering, especially for the filling all kinds of holes, grooves and concave edges. A surface filling technique based on LOOP feature and smooth outlines is proposed in this paper. The method is also performed on the basis of BrRep of CAD data and development support library ACIS. The filling surfaces fulfilling the requirement of stamping simulation can be generated fast by this method, and the parameters of smoothing operation can be controlled. The validity of this method is conformed by the results of the complex industry-forming panels.
