    Abstract

    The purpose of the present documentation is to provide the necessary information for numerical simulation of cold forging operations applying the new friction model based on simulative testing as described in /1/..The documentation describes how the friction stress depends on the surface pressure and tool temperature for four different combination of basic material, conversion layer and lubricant. Furthermore flow stress curves for aluminium, steel and stainless steel are given at varying slug temperatures in the range which can be reached in cold forming (25-200C).The documentation is divided into three main groups: friction modelling, stress/strain curves and other input data for numerical simulation.
