Digital Twin Framework Enabling Fleet-Level Feed Drive Systems Health Assessment and Maintenance Planning KU Leuven
The feed drive is one of the most critical systems used for the workpiece and tool's desired positioning and provides high rigidity by preloading. Its degradation exhibits significant machining errors (backlash) and vibrations which affect the product quality. The challenges, such as the unavailability of data for all failure modes, domain-specific data processing strategies and the black-box nature, and the high modelling uncertainty of ...
