In metal forming springback is a widely researched topic. It is generally referred to as the change of part shape that occurs upon removal of constraints after forming. In cutting this also occurs but on a much smaller level. Literature [1], [2], [3] shows divers results for mostly static or quasi-static experiments leading to simulations without velocityinfluence. Experiments done at IWF of ETH Zürich provide results with cutting speeds from vc =10 to 450 m/min for Aluminiumand Titanium. A cutting speed dependency is shown. Capacitive sensors mounted on a custom made tool holder while oblique cutting on a lathe provide online measurements. Experiments include different cutting edge radii, materials and cutting speeds demonstrating the influence of the springback on cutting forces, tool wear and surface roughness.
