How to Calculate Gage Repeatability Using the Average Range. I’m often asked to help Quality Engineers better understand how to perform Gage R&R calculations. So I decided to write several posts about the topic. Over the next few weeks I plan to roll out a number of posts I trust will enlighten everyone. In this […]
Measurement Systems Analysis
Reducing Gage RR can be problematic. Especially when the Gage employed and the process used to a collect the data is the best under the current circumstances. During the Measure phase of Six Sigma a Black Belt will perform a GRR study. This type of Measurement Systems Analysis (MSA) quantifies the error in repeatability and […]
How Statistical Control Charts can Detect Problems with Measurement System Discrimination! One of the simplest measurement system discrimination problems to detect is large units of measurement. When this is the case, the measurement system cannot detects changes between samples. This problem is widespread and detected by ordinary control charts.
