When performing a Gage R & R study, it is vital that the data be random in nature. It is standard practice to have multiple appraisers measure the same set of parts in a random order. It is common practice to use two or three appraisers and 5 or 10 parts . The purpose of this study is for example only and not an analysis of the process.What are variance components in a gage R&R study?
In ANOVA terminology, most Gage R&R studies have an ANOVA type data structure. A variance component analysis can easily be done in most software packages. The individual variance components provide estimates of error, operator and "true" product variance .What is a gage repeatability and reproducibility (R&R) study?
Gage Repeatability and Reproducibility (R&R) Gage Repeatability and Reproducibility is commonly referred as Gage R&R. It's a method to assess the measurement system's repeatability and reproducibility. In other words, Gage R&R studies are carried out to discover how much of the process variation is due to the measurement system.
