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