The aim of the project is the experimental and numerical investigation of the physical mechanisms that cause backward-whirl instabilities. These are to be investigated under special consideration of the contact conditions at the guide chamfers and taking into account inertial and damping forces. A simulation model is to be built which maps the relevant effects. With a suitable simulation model, it is possible to predict tool vibrations and process forces, thus saving time, costs and resources in the development of tools. An increase in the quality of the drilling by an optimized tool geometry without additional active damping elements is the aim of the project.

该项目的目的是对导致向后旋转不稳定性的物理机制进行实验和数值研究。这些需要在特别考虑引导倒角处的接触条件并考虑惯性力和阻尼力的情况下进行研究。将建立一个模拟模型来映射相关效果。通过合适的仿真模型，可以预测工具振动和加工力，从而节省工具开发的时间、成本和资源。该项目的目标是通过优化刀具几何形状而无需额外的主动阻尼元件来提高钻孔质量。
