In this paper, the friction behaviour in a severe bending process of a thick plate was investigated, taking into account both dry and lubricated conditions. Early experimental tests were performed to obtain mechanical properties of the low carbon steel AISI 1006, to be used as input in FE solver. Besides a 3D thermo-mechanical model based on FEM was developed to predict stress and strain distributions and final component dimensions. The second experimental series was composed of a coining process and a forming operation to reach the size of the final part. The analysis and the control of the friction conditions has permitted to obtain a product of higher quality that permitted to avoid all the secondary machining operations previously required.

Abstract
In this paper, the friction behaviour in a severe bending process of a thick plate was investigated, taking into account both dry and lubricated conditions. Early experimental tests were performed to obtain mechanical properties of the low carbon steel AISI 1006, to be used as input in FE solver. Besides a 3D thermo-mechanical model based on FEM was developed to predict stress and strain distributions and final component dimensions. The second experimental series was composed of a coining process and a forming operation to reach the size of the final part. The analysis and the control of the friction conditions has permitted to obtain a product of higher quality that permitted to avoid all the secondary machining operations previously required.
