Expanding a Gage study with extra factors


In expanded Gage studies, we are interested in including more than just an operator or part as factors in the Gage R&R. This is especially useful if the study is interested in investigating the differences across measurement devices, different labs, or even locations.

Here, we will look at a Gage R&R including one extra factor, a preparation method effect on the sample. In this recipe, the study looks at the force required to remove adhesive from a glass plate. The sample is a batch of adhesive, and the response is the force required to remove a test piece from a glass plate. Two operators prepare the samples and test the force of the adhesive.

Additionally, in this study, three different preparation methods are used to clean the glass plates before the adhesive is applied.

We will use the expanded Gage R&R to look at the effect of the preparation method, operator, and adhesive batch on the force measurements.
