Concept to determine thermo-elastic deformations by directly measuring local shifts using structurally integrated sensors (C03)

• Subject Area: Engineering Design, Machine Elements, Product Development ; Mechanics
• Term: from 2011 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 174223256

The main objective of subproject C03 is the metrological detection of thermo-elastic deformations during machining in three-axis machine tools by means of a retrofit sensor system. The overall approach includes the mechanical deformation model, the control integration methodology, and the sensor placement optimization methodology. The reliability of the correction concept depends on these components and will be examined in phase 3. After the concept was confirmed under real conditions in integration objects in the second phase, the applicability of the overall approach will be validated on practice-relevant use cases on demonstrators.
