Abstract

Boron alloyed steel is usually used in manufacturing of automotive part by hot stamping. Due to its unique properties, this material is comparatively expensive. Therefore an optimized size and shape of the blank is important in order to avoid material wastage after stamping operation. In this study, a blank for an automotive part called Front Impact Beam (FIB) was used as a case study. The objective was to minimize the material wastage after trimming to within +2mm. The effect of different blank sizes on the final stamped part is investigated by using commercial CAE software. The constraints considered in this study include minimum wrinkles and springback or distortion. Finally an improved blank optimization algorithm is developed.
