Abstract

The object of this paper is to clarify the effect of the temper of pure aluminum sheets on the surface flattening mechanism and friction behavior in the cup-ironing process. Ironing tests were carried out with cups drawn from three kinds of tempered pure a aluminum sheets. The results showed that on the die surface, the friction coefficient tends to increase with harder test cups. To understand this phenomenon, experiments with annealed cups were performed. Compared with the as -drawn cups, in the case of the annealed cups, the friction coefficient becomes smaller because the lubricant flowsmore easily into the contact interface and can be trapped there in.
