Abstract
Metalforming tribology is a science and technology of a huge system. At the midst of this system is situated the micro-contact mechanism. The micro-contact mechanism in the presence of lubricant have generally been classified into the regimes of boundary, mixed and hydrodynamic lubrication depending on the average lubricant film thickness and the surface roughnesses of tool and workpiece. In these mechanism, there proceeds mechanical interaction between the surface microstructures of workpiece and tool and the lubricant. First, this paper presents the micro-contact at the interface between tool and workpiece under each lubrication regime. Second, the micro-contact at the interface between tool and workpiece in sheet metals forming, and sheet rolling are explained.
