Summary:

With modern multipoint drawing equipment, it is possible to control the draw pins independently of each other. This gives the possibility to specifically change the normal force distribution between blankholder and workpiece regarding location and time. Investigations show that the effects which are achievable with multipoint drawing technology are only possible in conjunction with a changed blankholder design. The increase in the maximum drawing depth by approximately 57% were achieved. In addition to experimental work, numeric simulation is used to determin the necessary setting parameters
