Abstract

[This abstract is based on the authors' abstract.] Manufacturers and suppliers use quantitative quality measures to make objective decisions regarding product and process quality. Many use the precision-to-tolerance ratio to approve a measurement system, or use one or more measures of process capability to approve a manufacturing process. A measure used to assess the ability for two parties to communicate via dimension data is the correlation in repeat measurements. With the addition of a measure of process capability, a relationship between the three measures indicates a method for determining an acceptable level for the correlation criterion. This approach of plotting the quality measurement criteria defines the quality situation and facilitates improvement suggestions.
