Abstract
The aim of this research work is to study the inter-relationship, under controlled industrial conditions, among skin pass reductions, surface topography (characterized by 2D and 3D) roughness parameters, stampability and painted surface finish quality for automotive steel sheet stampings.Different surface textures obtained from cold rolling finishing have been evaluated in terms of paintability tests (rating and spectral curve) and tentatively related to roughness parameters (2D and 3D) obtained from the cold finished sheets. Some relevant tendencies have been established amongst these parameters.The results presented here are in accordance with other recently published research showing that there is a clear relationship between these parameters, and that further detailed studies are needed.
