Metrological characterization of measurement systems through monte carlo simulations, design of experiments and robotic manipulation

This paper proposes a procedure for performing the metrological characterization of multi-degrees of freedom measuring devices, that could be exploited for control and monitoring in the industry 4.0 context. The developed methodology is constituted by both a theoretical and an experimental phase. The metrological analysis is divided in the 3D kinematic modelling of the system, the computation of the measurement uncertainty using the Design of Experiments and Monte Carlo simulations, and the assessment of the experimental uncertainty in operational conditions as per the ISO Guide to the expression of Uncertainty in Measurement. The case study of an instrument for the measurement of 3D misalignment between two surfaces is eventually presented and discussed.
