The optimization of the incremental rolling as well as of the grinding of thermally coated surfaces within the process chain to produce forming tools furnished with a wear-resistant coating is in the focus of this subproject. The in the second funding period developed fast, adaptive, and robust numerical optimization algorithms are extended with respect to the considered models, restrictions, goal functionals, and optimization variables. The optimization of these finishing steps substantially contributes to the process chain optimization and noticeably accelerates it.

优化工艺链中热涂层表面的增量轧制和磨削，以生产带有耐磨涂层的成形工具，是该子项目的重点。在第二个资助期开发的快速、自适应和鲁棒的数值优化算法在所考虑的模型、限制、目标泛函和优化变量方面进行了扩展。这些精加工步骤的优化极大地促进了工艺链的优化，并显著加快了其速度。
