Inspection Strategies and Multiple Geometric Tolerances
Procedia CIRP, 2013 AbstractRecent years have seen an increase in the adoption of geometric tolerances. It is often possible to find several geometric tolerances defined on a single part. However, this poses inspection issues: the values of the geometric error may be interrelated; therefore, the presence of multiple tolerances should be considered in inspection design. In

Model-Based, Experimental Thermoelastic Analysis of a Large Scale Turbine Housing
Journal of Machine Engineering, 2022 Temporally and spatially unstable thermal conditions lead to inhomogeneous thermoelastic changes in the workpiece geometry. Consequently, non-negligible geometric deviations are evident, especially when measuring large workpieces with narrow tolerances,
