Abstract: To assess the tool-workpiece compatibility in metal forming, a friction test is carried out on a strip-ironing type tribometer, which can estimate quantitatively the effect of new surface ...

Abstract: To develop an anti-weldability test in metal forming, a strip-ironing type friction testing machine was devised to measure simultaneously normal and frictional forces acting on the die during ...

Abstract: The object of this paper is to clarity the surface flattening mechanism in the cup ironing process based on the lubricating mechanism. A new experimental apparatus for the ironing process was ...
