[ 1 ] - The Effect of Ridges to Improve Ductility and Reduce Deformation Energy in Deep-Drawing Process
In this research, two new methods that improve the drawing depth of deep-drawing processes have been introduced. In the first technique, by creating ridges on the punch surface, the stress concentration is decreased on the blank near the punch edge, in turn increasing the drawing depth. The second method is based on the principle of reducing resistant force in the flange area between the die, t...
