Repeatability and Reproducibility techniques for the analysis of measurement systems

•This research aims to analyze some metrological characteristics of measurement system.•Repeatability and Reproducibility features play an important role in the analysis of the measurements.•ANOVA and Gage R&G techniques are proposed and discussed.

This research was conducted with the aim of analyzing two of the main metrological characteristics of any measurement system: Repeatability and Reproducibility. Both of these features play an important role in the analysis of the measurements and they can give us a lot of information about who and what influences any measuring system. The analysis of Repeatability and Reproducibility is generally carried out through the use of the study Gage R&R. This study permits to understand which are the decisive factors in a measurement system, and, definitively, if the process is stable, that is under statistical control or out of statistical control.
