Abstract

A new deep-drawing apparatus is developed for examining the compatibility problem between the tool and the workpiece material in metal forming. The die consists of two parts divided coaxially, the radius part rotating at a desired speed and the flange part fixed. The division of the die makes it possible to control the meridian component of the frictional force on the die profile radius by changing the direction of frictional force with its rotation. The characterization of the apparatus is made by drawing tests of copper blanks with a sintered carbide die. The result shows that it is possible to estimate the absolute value of die profile friction in deep drawing by using the apparatus developed.
