In the recent years, loads on the sheet metal forming tools increased with the advent of high and ultra-high strength steels. On the other hand, market demand favors the use of rapid tooling technologies and thus alternative materials, which are softer than conventional tool steels. These recent trends result in severe wear on sheet metal forming tools and make the wear prediction more and more important. In this study, a wear prediction methodology by means of finite element analysis and deep drawing experiments is developed. In order to achieve a better accuracy, the wear propagation over loading period is modeled not with a constant wear coefficient but with wear coefficients as a function of accumulated wear work.
