FE-Modeling of Cold Rolling by In-Feed Method of Circular Grooves

The methods of cold rolling of rods are widely used in manufacturing industries to obtain pieces will? complex profiles. In this study complex profiles with grooves have been formed by in-feed methods using two rolls. An experimental system was constructed to record the process parameters. The micro-hardness has been measured by the Vickers method in an axial section of the rolled piece. The process has also been simulated by means of finite element calculations using the Abagus/Explicit code. The material behavior is described by using a 5-parameter strain-hardening law and by accounting for thermal effects at high strain-rates. Finally, a comparison is made between experimental and simulated results. (C) 2011 Journal of Mechanical Engineering. All rights reserved.
