Especially the automotive industry is under greatest pressure of reducing development times. Thus, requirements concerning deep-drawn work pieces to be manufactured are increasing constantly (e.g. demand for even lighter vehicles). Consequently, complexity of the forming tools’ dimensioning is continuosly growing. Geometies of the sheet metal parts as well as the purely mechanical functions of tools are growing ever more complex. Ultra high-strength steels and aluminium materials are increasingly being used, the experience of which regarding deep drawing properties is very limited up to now.
Therefore, deep drawing simulation is mostly applied in this area, enabling statements on feasibility, complexity and process reliability already in the run-up to process layout. It is an essential tool of process planning for the reduction of costs and development times.
Virtual process analyses provide workpiece-specific information on:
During deep drawing simulation, application parameters such as deformation degree, inlet radius or draw rate as well as forming and holding-down force can be optimized via computer long before the tool has been designed and installed in the press.
