What is a gauge R&R study?

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%.

  • Case study: Conroe Machine - Equator™
    Case study: Conroe Machine - Equator™

    Conroe, Texas, USA – Conroe Machine is doing what most machine shops only dream of – hard turning a family of parts around the clock in an unmanned cell that operates a ‘self controlled’ process. It integrates a Fanuc robot with the Equator™ gauging system, using Renishaw EZ-IO software to provide simple comprehensive communication functions, for 100 percent part inspection and auto-compensation of a twin-spindle Okuma 2SP-250 lathe. The cell also boxes and palletises finished parts. The company states that the turning cell paid for itself in an amazing 18 days.

  • Case study: Kishan Auto - Gauging time and costs cut by 80% and accuracy maintained despite a 21 °C range
    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%.

  • Case study: Eponsa - Equator could reduce waiting time to zero, it can gauge difficult features and the price is very competitive
    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.

    Case study: Meyer Tool - Aero-engine component maker Meyer Tool "softens" up hard gauge costs with software-driven Equator™ gauge

    A software-driven comparative gauge, Renishaw's new Equator system, is already starting to soften up the cost for numerous hard gauges at aero-engine component maker Meyer Tool, Cincinnati, OH. Meyer Tool designs, builds, and maintains dozens of these costly tools every year for in-process measurement.
