Theoretical and experimental tests to select suitable measuring procedures for calibration

Since many years the calibration of test equipments is one of the main tasks in the technology of length measurement. Through the reduction of tolerances within the manufacturing process the request for high quality of the measuring instruments and test procedures rises. The classification of test equipments depends on the roughness and the deviation of size, form and position. During the tests we analysed plug gauges and ring gauges whose size was changed in phases. The aptitude of test procedures with 2D- or 3D-measuring instruments can be identified with the help of the developed software.
