Assessment of Reliability of Measurement Data and Adequacy of the Measurement Systems in Improving Quality of Casting Products

The study summarises the analysis of reliability assessment of measurements of a selected critical property of a high-precision casting product. Measurement data must be sufficiently reliable to be used in decision-making relating to quality control and the selection of the casting manufacturing technology. The applied procedure is illustrated by study of the variability range of readouts depending on the measurement conditions, obtained by the computer methods. The applied R&R (Repeatability and Reproducibility) procedure is major component of the widely employed Measurement System Analysis (MSA).
