Abstract

During the manufacturing of work pieces, geometrical deviations from the
intended nominal geometry of the designer are inevitable. The procedure
of conformance testing defined in ISO 14253-1:2018-07 is used to ensure
the function of a work piece by verifying the geometrical compliance
with pre-defined tolerance specifications. Depending on the measurement
setup used for the validation step and the accuracy of the manufacturing
process, it is possible that the measurement uncertainty is large
enough to have a significant influence on the conformance evaluation.
The measurement uncertainty for optical measurement systems is
influenced by the surface properties of the test specimen. This
contribution aims to demonstrate the complete workflow for the
determination of the single point uncertainties for a given measurement
task in order to separate the local work piece deviations from the
systematic and random components of the measurement uncertainty. It
could be shown for a demonstration scenario that different necessary
coloring methods of polymer gear wheels, which are required to enable
measurements using structured-light scanning, have a measureable
influence on the local distribution of the measurement uncertainty. This
information could then be used for downstream processes in various use
cases, e.g. for the improvement of holistic tolerance simulation models
or the improvement of geometrical measurements using weighted regression
analysis.
