近几十年来，为了应对不断提高的质量标准，特别是汽车行业的质量标准，以及锻造行业日益激烈的国际竞争，有限元方法已成为金属成形领域低成本虚拟工艺设计的重要工具。考虑到精确的刀具磨损预测的优化工艺设计是提高整体金属成形工艺成本效率的一种途径。本文介绍的工作的主要目标是一种建模算法，该算法允许根据成形模拟过程中的几何更新来预测模具磨损。几何更新引起的接触面积变化导致模具磨损分布不同。它主要涉及芯片区域，这些区域承受着高热和机械负载。
In the recent decades the finite element method has become an essential tool for the cost-efficient virtual process design in the metal forming sector in order to counter the constantly increasing quality standards, particularly from the automotive industry as well as intensified international competition in the forging industry. An optimized process design taking precise tool wear prediction into account is a way to increase the cost-efficiency of the bulk metal forming processes. The main objective of the work presented in this paper is a modelling algorithm, which allows predicting die wear with respect to a geometry update during the forming simulation. Changes in the contact area caused by geometry update lead to the different die wear distribution. It primarily concerns the die areas, which undergo high thermal and mechanical loads.
