Gage R&R Folio: Data Tab

The Data tab of the gage R&R folio contains a control panel and a sheet with the following four columns for entering data:

• Part is the identifier for the part that was measured.

• Operator is the identifier for the person who performed the measurement.

• Reading is the measurement obtained from the gage under investigation.

• Trial is used to help you keep track of multiple trials that are used in a particular study. For example, in a crossed gage R&R study, the first measurement of a part by an operator would be trial #1, the second measurement by the same operator trial #2, and so on. These values are not used in the calculations.

As an example, suppose a scale used to weigh two parts (in pounds). Part 1 is measured four times: twice by Operator A and twice by Operator B. Part 2 is also measured twice by each operator. The resulting data is shown next.

For example, the first row shows that Part 1 was measured by Operator A, who obtained a measurement of 9.856 pounds.
