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.
