在金属成形中，回弹是一个被广泛研究的课题.它通常被称为零件形状的变化，发生在成形后取消约束。在切割中也会发生这种情况，但程度要小得多。文献[1]、[2]、[3]显示了大多数静态或准静态实验的不同结果，导致模拟没有速度影响。在苏黎世联邦理工学院的IWF进行的实验提供了切割速度从vc=10到450 m/min的结果。示出了切割速度依赖性。电容传感器安装在一个定制的工具保持器，而在车床上斜切提供在线测量。实验包括不同的切削刃半径，材料和切削速度演示的影响，回弹对切削力，刀具磨损和表面粗糙度。
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.
