SPP 1057: Spanen metallischer Werkstoffe mit hohen Geschwindigkeiten

新型刀具材料、高性能主轴系统和智能驱动系统使机床切削速度大幅提高成为可能。高速切削可以提高表面质量，降低生产成本。因此，它对飞机工业、模具制造、喷气推进发动机的生产以及汽车工业的广泛应用具有重大意义。尽管如此，科学基础的高速切削是不为人所知。优先项目1057“高切削速度下的金属切削”侧重于应用实验分析和仿真工具研究切屑形成机制。材料性能和能量耗散是研究的目的。在此基础上，建立了切屑形成区模型。

New tool materials, high performance spindle systems, and intelligent driving systems make possible a drastic increase in the cutting speed for machine tools. High speed cutting can lead to enhanced surface qualities and lower production costs. It is therefore of major interest for the aircraft industry, die and mould manufacture, the production of jet propulsion engines, as well as for a wide range of applications in the automotive industry.Despite of this, the scientific basics of high speed cutting are not well known. The priority programme 1057 "Metal Cutting at High Cutting Speeds" focuses on the chip forming mechanisms applying experimental analysis and simulation tools. The material behaviour as well as the energy dissipation are the aims of the investigations. Based on these results a model for the chip forming zone is being established.
