【 摘 要 】

Deep drawing is a sheet metal forming process which is widely used in manufacturing parts for automobile and air craft industries. In this paper, the mechanism of deformation, effect of the geometrical parameters involved and the defects encountered in the process are presented and discussed. These include: the radial clearance percentage, punch and die profile radii. Despite the number of publications on the subject, there is still a great demand for further research. Recent experimental investigation on the effect of radial clearance percentage, punch and die profile radii on their autographic records (punch load- punch displacement curves) and on quality of the produced blanks is carried out and the results are presented and discussed. It was found that the maximum drawing force decreases with increase of the die profile radius and increases by increase of the punch profile radius. Furthermore, the liability of the produced cups to wrinkle increases by the increase of both punch and die profile radii being more influenced by the die profile radius.
