Manual tool reworking is one of the most time-consuming stages in theudpreparation of a deep drawing process. Finite Elements (FE) analyses are now widelyudapplied to test the feasibility of the forming process, and with the increasing accuracy of theudresults, even the springback of a blank can be predicted. In this paper, the results of an FEudanalysis are used to carry out tool compensation for both springback and tool/pressuddeformations. Especially when high-strength steels are used, or when large body panels areudproduced, tool compensation in the digital domain helps to reduce work and save time in theudpress workshop. A successful compensation depends on accurate and efficient FE-prediction,udas well as a flexible and process-oriented compensation algorithm. This paper is divided inudtwo sections. The first section deals with efficient modeling of tool/press deformations, butuddoes not discuss compensation. The second section is focused on springback, but here theudfocus is on the compensation algorithm instead of the springback phenomenon itself.
