Influence of Selected Measurement Conditions on the Reliability of the Representation of Ring and Rim Features
摘要
Metrology of geometric quantities is experiencing its development towards Metrology 4.0 or metrology of the future. Coordinate measuring technology, which has replaced classical geometric size metrology in many respects, requires an in-depth analysis of accuracy issues related to the influence of measurement conditions on the reliability of the measurement results obtained. This paper presents an analysis of the selection of a coordinate measuring system for large-size rim and ring type components. These components, although assumed to have low-complexity shapes, are nevertheless characterised by difficulties in adopting a measurement base and coordinate system. The influence of measurement point density and scanning speed on the representation of geometric features for contact and optical measurement systems is presented. An assessment of measurement accuracy by estimating measurement uncertainty is also presented.
