What is a gauge R&R study?

This text will be replaced

The purpose of a gauge R&R study is to demonstrate the capability of a gauging device to measure a specific component.

Type 1 - simple repeatability trials with one operator, one part and multiple repetitions. The following values are used to indicate whether a measurement system is capable of measuring a feature consistently and accurately:

Cg: Compares tolerance with measurement variation.
Cgk: Compares tolerance with measurement variation and bias.

Both figures should be greater than 1.33 to show that the measurement system is capable, in some cases values greater than 1 might be acceptable. Cg indicates the spread of measurement values, Cgk also includes the bias, the offset of the group of measurement values from the nominal.

Type 2 - prove the measurements provided by the Equator system are repeatable and reproducible, regardless of operator, for a specific feature. Tests are performed with multiple operators, multiple parts and multiple repetitions. The measurement uncertainty due to the Equator for that particular feature is expressed as a percentage of the tolerance, in most cases this is expected to be lower than 10% but may be up to 20%.

(IN217) Case study: Kishan Auto - Gauging time and costs cut by 80% and accuracy maintained despite a 21°C range
Kishan Auto parts Pvt. Ltd., Rajkot (Gujarat, India) is a world leader in the manufacture of connecting rods for major names in the car, compressor, heavy commercial vehicle, tractor, marine engine and earth mover manufacturing industries. Kishan recently purchased a Renishaw Equator flexible gauging comparator, and have seen an immediate reduction in cost and gauging cycle times of more than 80%. Additionally, despite shop floor temperature variations of more than 21°C (43°F), measuring performance has been unaffected due to Equator’s unique comparator method which uses master parts calibrated on Kishan’s co-ordinate measuring machine (CMM).

(IN215) Case study: Eponsa - “Equator™ could reduce waiting time to zero, it can gauge difficult features and the price is very competitive”
Eponsa, a manufacturer of automotive components located near Barcelona, Spain, has purchased a versatile and innovative shop-floor comparative gauge, the new Renishaw Equator, to check the quality of stamped parts and assemblies. This will reduce non-productive waiting times to a fraction of the time taken now, while maintaining the high quality and manufacturing efficiencies that are critical for the success of an automotive subcontractor. Other advantages for Eponsa are that Equator can scan the form of part features with its SP25 probe and change styli with the stylus change rack, included as standard, to check a large variety of parts.
