Minimisation of Pose-Dependent Regenerative Vibrations for 5-Axis Milling Operations
Journal of Manufacturing and Materials Processing, 2021 The machining of free-formed surfaces, e.g., dies or moulds, is often affected by tool vibrations, which can affect the quality of the workpiece surface. Furthermore, in 5-axis milling, the dynamic properties of the system consisting of the tool, spindle
