Abstract

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.
