18 GAGE R&R STUDY CROSSED
In the 18th Minitab tutorial, we will look at the final assembly of Smartboard Company and accompany the quality team as they carry out a so-called measurement system analysis, Gage R&R study crossed. In the first part of our multi-part Minitab tutorial, we will first familiarize ourselves with the fundamentals in order to understand the most important definitions, such as measurement accuracy, repeatability, and reproducibility, as well as linearity stability and resolution. Well equipped with the fundamentals, we will then move on to the practical implementation of crossed measurement system analysis in the second part, and take the opportunity to learn the difference between crossed and nested measurement system analysis. We will learn that there are basically two mathematical approaches to performing crossed measurement system analysis: One is the ARM method and the other is the ANOVA method. In order to better understand both methods, we will first carry out our crossed measurement system analysis using the ARM method in the second part of this training unit and, for comparison, carry out a crossed measurement system analysis using the ANOVA method on the basis of the same data set in the third part of this training unit. We will actively calculate both methods manually step by step, and derive the corresponding measurement system parameters, in order to understand how the results were generated in the Minitab output window.
