Improving machining performance of in-use machine tools with active damping devices
Produktivitätssteigerung von Werkzeugmaschinen durch aktive Dämpfung
Machine tool productivity is governed by machining stability of the system, which varies as a function of the position of the machine in the workspace. To enhance machine tool performance over the entire workspace, this paper presents an approach that integrates an active damping device to increase the dynamic stiffness of structural modes that limit productivity. The actuator is sized and selected based on defined performance objectives of an increase in productivity. Device performance is simulated and validated experimentally, and it is demonstrated that improvements of up to 22% in productivity and part surface quality is possible with such devices.
