| Abstract: |
The modern definition of traceability intimately links the concepts of calibration (i.e., connection to the SI unit) and measurement uncertainty. In a typical coordinate measuring machine (CMM) measurement problem the measurement under consideration bears little resemblance to the measurand or validity conditions of the CMM calibration. Consequently, the metrologist must develop methods to combine the known CMM calibration information together with the measurement specific factors to generate a task specific uncertainty statement. This paper discusses the relationship between including traceability, calibration and measurement uncertainty issues in a manner intended to be informative to understanding traceability for industrial measurements. |
