Abstract— The design of new forming tools gets more problematic as the geometries get more complicated and the materials less formable. The idea with this project is to evaluate if an implementation of simulation software in the designing process, to simulate the forming process before actually building the tools, could help avoid expensive mistakes.
In order to see the effect of die deformation on the forming of sheet metals, the draw-ins, strains, and spring backs of an automotive fender panels are numerically simulated considering the die deformation, which is found by the simultaneous structural analysis of press and dies. By coupling the forming analysis and the structural analysis, the die deformation is simultaneously taken into account in the forming process.

I. INTRODUCTION
In the recent years, the role and importance of metal forming processes in manufacturing industry have been continuously increasing primarily due to its material and cost effective nature. It is further emphasized by the recent advances in tools, materials and design, which in turn provide significant improvements in the mechanical properties and tolerances of the products. Moreover, in the recent years metal forming develops in the direction of net-shape or near-net-shape manufacturing to reduce the need for subsequent machining operations and to minimize the total manufacturing cost. Consequently, in metal forming both the process planning and the tool design represent very important and complex tasks.
The global competition also requires that manufacturing industry besides the skill and the experience accumulated in the shop practice should increasingly utilize proven techniques of Computer Aided Engineering for rapid and cost effective process design and tool manufacturing. The application of various methods of Computer Aided Engineering has become one of the most important topics in manufacturing industries and particularly in the automotive industry.
