Evaluation of Capability of Measuring Device on the Basis of Diagnostics

Abstract:

In capability evaluation of measuring devices on the basis of diagnostics, it is important to compare variability of measurement with certain proportion of tolerance zone width of observed qualitative parameter. Determined index of capability of particular measuring device indicates its applicability for inspection of selected qualitative parameters in a given tolerance range. The paper is focused on evaluation of capability of digital micrometer DIGIMATIC within its entire measuring range (0 to 25mm) by the means of capability index Cgm and Cgmk. Evaluation of capability of the given measuring device was carried out by repeated measurements of standards with dimensions representing lower, middle and upper range of the measuring instrument at given accuracy (2μm) of measuring device.
