GR&R: Understanding Sources of Error in Mechanical Testing Results

GR&R: Understanding Sources of Error in Mechanical Testing Results

Gage repeatability and reproducibility, also known as GR&R, is a type of statistical analysis that is often performed by quality and product engineers as a method of test equipment validation and verification. The purpose of this paper is to highlight a variety of error sources, and provide suggestions and guidelines for conducting a successful GR&R study.
