Description/Purpose
Perceived product variability is composed of both true product variation and measurement system variation. This class will provide the participant with the methods to identify and quantify different sources of gauge variability/error. A hands-on workshop will demonstrate the techniques (using customer supplied parts and gauges if possible). Further, there is inconsistency in, and frequent misinterpretation of the terminology used when referring to measurement systems. Definitions will be provided and discussions encouraged. The content of this class is focused on measurement systems that yield continuous (variable) data from non-destructive testing, although some discussion will be geared toward dealing with attribute data and destructive testing.
