Part quality improvement in flexible roll forming of a combined variable width and depth component

Abstract Flexible Roll Forming (FRF) is an advanced manufacturing process that can be used to form long and complex part families from hard materials for the automotive truck industry. However, depending on complexity material strength shape defects such as end flare, springback twist occur. In this work a high (Sled runner) produced 3 steels; component combines variations in width depth. The optimum forming sequence identified produce without any flange wrinkles. addition this, new over technique introduced overcome flare springback. experimental results are evaluated discussed with numerical analysis suggest presented technology enables manufacture of components accordance specifications quality standards.
