Abstract

Trend in the automotive industry towards fuel efficient, lightweight and sustainable transport has highly contributed to developing new high strength steel families. However, going from ordinary mild steel to using high strength steel requires new manufacturing processes to face new formability issues and springback problems. On the other hand, to guarantee sustainable development, modern production processes are needed to respond to actual industry demands in flexibility, productivity and accuracy. Flexible roll forming allows the production of profiles with variable cross sections along longitudinal direction. But this flexibility brings other geometrical errors in the part, due to the complicated stress states generated during the process. In the present paper, different forming paths and mechanical configurations have been studied in order to optimise the process and obtain a sound part using a DP600 high strength steel. Also, numerical and experimental results are presented for locally heated roll forming process.
