Load-optimized design of PVD tool coatings

刀具涂层对刀具的切削性能有重要影响。涂层性能对工艺和材料的适应性为提高生产率和工艺可靠性提供了相当大的潜力。由于在涂层生产和切削行为领域缺乏知识，目前开发适应性涂层系统需要大量的经验努力。为了更深入地了解涂层刀具的磨损行为并减少所需的加工试验次数，一种可能性是使用基于有限元的切屑形成模拟。到目前为止，模拟适配涂层系统的巨大潜力仅在正交切割中显示，因此还不能在工业上开发。因此，工艺和负载特定的涂层刀具的广泛工业应用需要将当前的知识转移和扩展到其他工业应用的制造工艺和涂层系统，例如使用PVD-TiAlN涂层硬质合金刀具的外部纵向车削。因此，计划转移项目的主要目标是将前两个项目中的研究成果与应用合作伙伴WALTER AG一起转移到相关涂层系统和加工工艺的工业边界条件中。应用程序合作伙伴将能够有效地在新的和进一步的工具开发中使用模拟，从而提高其竞争力。

The coating of cutting tools significantly influences their cutting behavior. The adaptation of the coating properties to process and material offers considerable potential for increasing productivity and process reliability. Due to a lack of knowledge in the areas of coating production and cutting behavior, the development of adapted coating systems is currently associated with great empirical effort. One possibility for generating a deeper understanding of the wear behavior of coated cutting tools and for reducing the number of required machining tests is the use of FE-based chip formation simulations. So far, the great potential of simulatively adapted coating systems has only been shown for the orthogonal cut and can therefore not yet be exploited industrially. A broad industrial application of process- and load-specific coated tools therefore requires the transfer and expansion of the current state of knowledge to other industrially applied manufacturing processes and coating systems, such as external longitudinal turning with PVD-TiAlN-coated carbide tools. The main objective of the planned transfer project is therefore to transfer the findings developed in two preceding projects together with the application partner WALTER AG to industrial boundary conditions with regard to the relevant coating systems and machining processes. The application partner will be able to use the simulation in the new and further development of tools efficiently and thus to increase its competitiveness.
