For the case of low production volumes, as in the design process, deep drawing tools can be made of polymers. In these tools different regions of stiffness can be created by use of springs or actuators. Actuators allow the temporal variation of stiffness while springs allow just a local adjustment. With the use of tools with such stiffness varying elements it is possible to reduce the springback and to improve the forming quality of the final part. In the experiments, deep drawing tools are made of polymers and elements for the stiffness adjustment are positioned in the die and in the blankholder. Such stiffness varying elements are positioned at the radii where springback can be reduced by increasing tension in the part by adjusting the stiffness to a suitable level. Actuators allow smooth changes of stiffness during the forming process. Finite element method (FEM) based simulations of the processes are also performed. The comparison of results is carried out and a profile of optimal variation of tool stiffness is generated to minimize the springback. In the experiments a small reduction of geometry deviation of the parts could be reached by varying the stiffness with springs and actuators placed into the die.",

Especially the large amount of industrial participants proves the relevance of these topic for the economy. Due to that fact we would like to meet your expectations with the second conference „Tools and Technologies for Processing Ultra High Strength Materials“ from September 19th – 20th, 2013. We want to provide a forum for a productive exchange between science and industry.",
