Model-Based Thermoelastic State Evaluation of Large Workpieces for Geometric Inspection

Beschreibung

Temporally or spatially unstable thermal conditions during geometric inspections lead to transient or inhomogeneous thermoelastic changes of the workpieces to be inspected. This results in non-negligible measurement deviations, especially for large workpieces with narrow tolerances, e.g. turbine components or gear parts. This work focusses on this problem and provides a model-based solution approach for the determination of workpiece temperature-related measurement deviations and uncertainties.
