Integrating the continuous improvement of measurement systems into the statistical quality control of manufacturing processes: A novel link

Reliability in measurements is a requirement for quality-oriented organisations. A novel link is presented in this work for the integration of the continuous improvement loop of measurement systems into the statistical quality control of manufacturing processes. The proposal is based on the Index of Contamination of the Capability (ICC) and the Golden Rule of Metrology. It is expressed through clear-cut decision rules that consider the uncertainty of measurement, the intended use of the measurements and the risk of inaccurate measurements. The proposal makes it possible to improve production quality. To facilitate its application, an equivalent graphical approach is provided. (C) 2012 CIRP.
