Forming limit curves are very important for the prediction of failure during sheet metal forming both in practical forming operations and particularly in numerical simulations. The reliability of numerical simulations in sheet metal forming processes is strongly influenced by the reliability of forming limit curves. Therefore, both the theoretical aspects and the experimental determination of the forming limit curves are challenging problems for scientific researchers and industrial practitioners as well. There are various experimental techniques and mathematical models used to determine the forming limit curves. In spite of the standardization efforts made recently by several institutions world wide, there are still significant differences in determining the forming limit curves. Recently, a new, complex measuring system capable for the automatic determination of FLCs was installed at the Department of Manufacturing Engineering. In this paper, first a short overview will be given on the theoretical background of FLCs, then the application of the complex measuring system will be shown.
