This research project aims to improve the dynamic behaviour of machine tool spindles by integrating damping structures directly into additively manufactured spindle components. Vibrations in machine tools reduce surface quality, productivity, and tool life. To address this challenge, a topology-optimized spindle flange with integrated damping elements will be developed using Laser Powder Bed Fusion (PBF-LB/M). Based on previous research on structural optimization and particle damping, different flange concepts with internal cavities filled with damping materials (e.g., metal powder or oil) will be designed, simulated, manufactured, and experimentally validated. Static and dynamic tests on test rigs and machine tools will evaluate stiffness, damping performance, and long-term durability. The project aims to transfer scientific results into industrial applications in cooperation with WEISS Spindeltechnologie GmbH and to establish new design approaches for high-performance, vibration-optimized machine tool spindles.
