Load-optimized design of PVD tool coatings

刀具涂层对刀具的切削行为有重要影响。涂层性能与工艺和材料的适应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割行为方面缺乏知识，目前开发适应涂层的系统需要大量的经验工作。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测试次数，一种可能的方法是使用基于有限元的切屑形成模拟。到目前为止，模拟适应涂层系统的巨大潜力只在正交切割中表现出来，因此还不能工业化开发。因此，工艺和载荷专用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，计划中的转让项目的主要目标是将前两个项目中与应用合作伙伴沃尔特股份公司一起开发的成果转移到与相关涂层系统和机械加工工艺有关的工业边界条件。应用伙伴将能够有效地在新的和进一步的开发工具中使用模拟，从而增加其竞争力。

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.
