摘要在金属加工中使用冷却润滑剂可提高刀具寿命和工件质量，并提高生产系统的整体可持续性。除了履行这些主要功能外，机械加工过程的重点也与减少环境污染有关。这可以例如通过优化刀具冷却通道的布置来实现。因此，刀具的活动刃口应有效地提供足量的冷却润滑剂。摩擦学应力的分析是相当困难的，因为复杂的接触区是不可接近的。因此，光学研究往往仅限于观察切屑的形成或分析过程，而不考虑切屑的影响。本文提出了一种创新的方法，该方法考虑了冷却润滑剂的分布和切屑的形成，从而能够更深入地三维了解内冷却通道钻削过程中的切屑形成区。将基于有限元方法的切屑形成模拟与计算流体力学流动模拟相结合。通过这种方式，克服了不同几何模型之间的差异，这些差异不允许由于缺少界面而联合生成任何数值信息。
ABSTRACT The use of cooling lubricants in metal machining increases both the tool life and the quality of workpieces and improves the overall sustainability of production systems. In addition to fulfilling these main functions, the focus of machining processes is also related to the reduction of environmental pollution. This can for example be achieved by an optimized arrangement of the cutting tool cooling channels. Therefore, the active cutting edges of the tool should be effectively supplied with a sufficient amount of cooling lubricant. An analysis of the tribological stress is rather difficult because the complex contact zone is inaccessible. Hence, optical investigations are often limited to only observing the chip formation or analyzing the process without considering the influence of the chips. This article presents an innovative method, which enables a deeper three-dimensional insight into the chip formation zone during drilling with internal cooling channels, considering the cooling lubricant distribution and chip formation. The chip formation simulation based on the finite element method and the computational fluid dynamics flow simulation are combined. In this way, the differences between the different geometric models that do not allow any joint generation of numerical information due to missing interfaces are overcome.
