# Gage R&R Inspections | CPK study | 3D ProScan



CPK / GR\&R Inspections
=======================

### **About**

Gage Repeatability \& Reproducibility (Gage R\&R) inspections are an equally a critical component in the validation of traditional metrology equipment and measurements for examination. Above all, the primary point of a GR\&R is to determine if the inspection instrument and the individual inspectors performing the measurements can obtain data accurately and efficiently in future analyses.

### **How it Works**

Using Minitab software, 3D ProScan will calculate the Gage R\&R values for each measurement and piece of equipment or tool across the entire inspection. Typically a Gage R\&R consists of 3 Trials of 3 Operators of 10 parts, totaling 90 inspected pieces (10 Parts x 3 Trials x 3 Operators), but we can accommodate your companies exact needs. If needed, for instance, the total number of parts, inspectors, and trials can be changed to your specifications.
