| Zusammenfassung: | Pin gauges are widely used in various applications, i.e. for gauging, as setting standards for mechanical and optical diameter measuring instruments, or for screw gauge calibration. Form deviations and surface roughness have a different influence dependent on the subsequent application of these gauges. In this paper we discuss how pin gauges are preferably calibrated and which measurands are to be determined for which application. In particular, the elastic deformation due to the measurement force and the determination of the form deviation are discussed. For the latter, an instrument based on three-point centerless roundness measurement is presented. The measurement methods and the best measurement capabilities are validated by internal comparisons between different instruments. |
