In recent decades, considerable progress has been made in all sub-disciplines of machining, for example in the simulation of cutting processes, in the design of tools and machine tools, or in the coating of tools with wear-resistant hard material coatings. R&D work in manufacturing technology is very closely interlinked with the field of tribology, particularly with regard to studies on the wear behavior of tools. The interactions between tool and workpiece during machining are of such a complex nature that cooperation between different disciplines is necessary to clarify them. This application will therefore use expertise from the fields of tribology, coating technology, materials science and manufacturing technology to work together on this topic. In particular, the focus is on understanding the wear behavior of coated tools as a function of the stress spectrum, in order to be able to make a knowledge-based tool/coating selection in the future that leads to higher component surface qualities and tool life. The industrial standard in the machining of metals with geometrically defined cutting edges are tools with a hard coating that significantly increases tool life. Since this highly wear-resistant coating is exposed to high temperatures and sliding speeds during machining, wear results in a chemical and mechanical change in the hard coating and complex tribological behavior. Today, this behavior can only be insufficiently described multiscale by simulation, since the effect of all possible influencing variables is not completely understood, and therefore usually does not allow a precise evaluation and prediction of the wear condition of the coated tools in the context of machining. With the results of this research work, it will be possible to predict the suitability of a tool coating for any kind of process parameter combination and workpiece material-tool combination in the HPC process. This leads to an optimization of the tool use, a reduction of the tool wear and at the same time an increased productivity.

近几十年来，机械加工的所有子学科都取得了相当大的进展，例如在切削过程的模拟、刀具和机床的设计或在刀具上涂覆耐磨硬质材料涂层。制造技术的研发工作与摩擦学领域密切相关，特别是在工具磨损行为的研究方面。加工过程中刀具和工件之间的相互作用是如此复杂的性质，不同学科之间的合作是必要的，以澄清他们。因此，该应用程序将使用来自摩擦学，涂层技术，材料科学和制造技术领域的专业知识，共同致力于这一主题。特别是，重点是了解涂层刀具的磨损行为作为应力谱的函数，以便能够在未来进行基于知识的刀具/涂层选择，从而提高部件表面质量和刀具寿命。在加工具有几何形状限定的切削刃的金属时，工业标准是具有硬质涂层的刀具，该硬质涂层显著增加了刀具寿命。由于这种高耐磨涂层在加工过程中暴露于高温和滑动速度下，磨损会导致硬质涂层发生化学和机械变化，并导致复杂的摩擦学行为。如今，这种行为只能通过模拟进行多尺度描述，因为所有可能的影响变量的影响并不完全清楚，因此通常无法精确评估和预测加工环境中涂层刀具的磨损状况。随着这项研究工作的结果，它将有可能预测的任何一种工艺参数组合和工件材料的工具组合在HPC过程中的工具涂层的适用性。这导致刀具使用的优化、刀具磨损的减少以及同时生产率的提高。
