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.

切割工具的涂层显着影响其切割行为。涂料特性对过程和材料的适应为提高生产率和过程可靠性提供了巨大的潜力。由于缺乏涂料生产和切割行为领域的知识，因此，改编的涂料系统的发展目前与巨大的经验努力有关。对涂层切割工具的磨损行为有更深入的了解并减少所需的加工测试的数量的一种可能性是使用基于Fe的基于Fe的芯片形成模拟。到目前为止，仅显示正交切割的模拟涂层系统的巨大潜力，因此尚未在工业上被利用。因此，开发和负载特异性涂层工具的广泛工业应用要求将当前知识状态转移和扩展到其他工业应用的制造过程和涂料系统，例如使用PVD-Tialn涂层的碳化物工具进行外部纵向转弯。因此，计划转移项目的主要目的是将与应用程序合作伙伴Walter AG一起在相关的涂料系统和加工过程方面转移到工业边界条件上。应用伙伴将能够在新的和进一步开发工具的新开发中使用模拟，从而提高其竞争力。
