Abstract
Process damping is an important effect to avoid chatter vibrations. It is commonly modeled as a force, which can be calculated by multiplying the indented workpiece volume with a process damping coefficient. However, the coefficient strongly varies depending on the chosen determination method. In this paper, the coefficient is determined by planing tests with a chamfered tool with negative chamfer angle and varying chamfer length (62 - 275 µm). Thereby, the workpiece is indented with a defined volume. Additionally, microstructure images are created to identify workpiece deformations. The results show decreasing coefficients with increasing indentation volume due to increasing plastic deformation.
