The proper determination of friction condition during metal forming operations is imperative for successful process design and production of parts. Through the years, various methods of determining the friction condition have been proposed, but all methods have some drawbacks. In this study, a new type of friction test named tip test based on backward extrusion of AL6061 - O is proposed. The experimental set-up of this method induces the formation of a sharp radial tip on the extruded end of the workpiece. It has been found that the simple geometrical measurement of this radial tip position can be used to effectively determine the friction condition.
