Many examples from industry show the advantages of this technology. However, the influence of high cutting speeds on machine tool, tool and workpiece quality have to be known. The current work describes the thermal and dynamical conditions in high speed turning and their influence on chip formation, resultant forces, temperatures, surface quality and tool wear. The examination consist of cutting experiments using conventional and newly developed setups. An example for the latter is a setup to take in-situ photos of the cutting process. Furthermore, cutting simulations using Finite Elements were conducted. To distinguish workpiece dependent mechanism from those caused by high cutting speeds, three different workpiece materials were examined. These are a medium carbon steel (Ck45N or AISI 1045), a wrought aluminum alloy (AlZnMgCu1,5 or AA 7075) and the titanium alloy TiAl6V4. The experimental results are used to verify the cutting simulation. Using a commercially available FE-code and new descriptions of material behavior at high strain rates, different mechanism of chip formation were simulated.
