How Many Types of Gage R&R Studies are There?

QI Macros has nine easy-to-use Gage R&R Excel templates.

The goal of Gage R&R (repeatability and reproducibility) studies is to minimize the amount of variation and error introduced by measurement, so that you can focus on part variation. The type of Gage R&R study you perform depends on your parts and what you want to learn from a test.

QI Macros contains templates for these types of Gage R&R studies:
