Abstract
The object of this paper is to clarify the surface flattening mechanism in the drawing-ironing process based on the lubricating mechanism. A new experimental apparatus for the drawing-ironing process was made and experiments on ironing were carried out with aluminum cups using various lubricants and reductions in thickness. The experiments revealed that on the die surface the friction coefficient becomes minimum under the appropriate conditions of viscosity of lubricants and reduction in thickness. It was also confirmed that the cup surface is best flattened under conditions where the minimum friction coefficient appears.
