Gauge R&R study

Gauge R&R type 1

Gauge R&R type 1 tests are simple repeatability trials with one operator, one part and multiple repetitions. Results show gauge repeatability.

Test conditions gauge R&R type 1

Gauging cycle time55 sec
Repetition32

Gauge R&R type 2

Gauge R&R type 2 tests involve multiple operators, multiple parts and multiple repetitions. Results give an indication of real world conditions, including factors such as gauge repeatability, fixture distortion and operator  inconsistencies.
