Paper Title:
Improving the Quality in Deep Drawing of Rectangle Parts Using Variable Blank Holder Force
  Abstract

Wrinkling and tearing are the main failure modes in sheet-metal forming. Wrinkle may occur at the start of a punch stroke if the blank-holder force (BHF) is too low, and tearing may occur at the end of a stroke if the BHF is too high. The BHF is important for deep-drawing because of an effective way to promote deep formability sheet metal. They can be reduced or eliminated by manipulating a suitable BHF during sheet-metal forming. This paper presented an attempt to determine the effect of variable BHF on the tearing and wrinkling and investigated using 08Al sheet metal. The experiment show that tearing and wrinkling can be eliminated and the quality of deep drawing of rectangle parts can be improved using variable BHF.
