Springback in metal cutting with high cutting speeds

Nikolas Schaal, Friedrich Kuster, Konrad Wegener, Volker Schulze
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 [1-3] shows divers results for mostly static or quasistatic experiments leading to simulations without velocity influence. Experiments done at IWF of ETH Zürich provide results with cutting speeds from v c =10 to 450 m/min for Aluminium and Titanium. A cutting

Experiments include different cutting edge radii, materials and cutting speeds demonstrating the influence of the springback on cutting forces, tool wear and surface roughness.
