26、oduction This part of ISO 15530 is a Geometrical Product Specification (GPS) and is to be regarded as a general GPS document (see ISO/TR 14638). It influences chain link 6 of the chain of standards on size, distance, radius, angle, form, orientation, location, run-out and datums. The ISO/GPS Masterp

27、lan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this standard is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this document, unless othe

28、rwise indicated. For more detailed information on the relation of this standard to the GPS matrix model, see Annex B. Coordinate measuring machines (CMMs) have become essential for the verification of geometry in industry. According to the ISO 9000 series of standards, in a quality management system

29、, the relevant measuring equipment is required to be calibrated against certified equipment having a known and valid relationship to internationally or nationally recognized standards in order to establish traceability. According to the International vocabulary of basic and general terms in metrolog

30、y (VIM), a calibration comprises besides the establishment of the relationship between the measured and the correct values of a quantity the uncertainty evaluation in the final results (measurands) of the measurement task. However, uncertainty evaluation methods covering the errors arising in the in

31、numerable measurement tasks a CMM can actually perform are often very complex. In these cases, the risk of an unrealistic estimation of task-related uncertainty is likely to arise. The aim of this part of ISO 15530 is to provide an experimental technique for simplifying the uncertainty evaluation of

32、 CMM measurements. In this experimental approach, measurements are carried out in the same way as actual measurements, but with calibrated workpieces or measurement standards of similar dimension and geometry instead of the unknown objects to be measured. The description of this experimental techniq

33、ue to evaluate measurement uncertainty is the key element of this part of ISO 15530. The standardization of such procedures for the uncertainty evaluation serves the worldwide mutual recognition of calibrations and other measurement results. This part of ISO 15530 is applicable for non-substitution

34、measurement of workpieces or measurement standards, where the measurement result is given by the indication of the CMM. Furthermore, this part of ISO 15530 is applicable for substitution measurement, where, in opposition to the non-substitution measurement, a check standard is used to correct for th

35、e systematic errors of the CMM. The latter will generally decrease the measurement uncertainty and is often used, especially in the field of gauge calibration. This part of ISO 15530 describes one of several methods of uncertainty evaluation, which will be outlined in later ISO documents. Because of

36、 the experimental approach, it is simple to perform, and it provides realistic statements of measurement uncertainties. The limitations of this method can be summarized as: the availability of artefacts with sufficiently defined geometrical characteristics, stability, reasonable costs, and the possi

37、bility of being calibrated with sufficiently small uncertainty. DIN EN ISO 15530-3:2012-01 EN ISO 15530-3:2011 (E) 4 1 Scope This part of ISO 15530 specifies the evaluation of measurement uncertainty for results of measurements obtained by a CMM (coordinate measuring machine) and by using calibrated

38、 workpieces or measurement standards. It provides an experimental technique for simplifying the uncertainty evaluation of CMM measurements, whose approach (substitution measurements) leads to measurements being carried out in the same way as actual measurements, but with calibrated workpieces of sim

39、ilar dimension and geometry instead of the unknown workpieces to be measured. Non-substitution measurements on CMMs are also covered, as are the requirements of the uncertainty evaluation procedure, the measurement equipment needed, and the reverification and interim check of the measurement uncerta

40、inty. NOTE The evaluation of measurement uncertainty is always related to a specific measuring task. 2 Normative references The following referenced documents are indispensable for the application of this document.
