4、ument comprises 26 pagesDIN EN ISO 10360-6:2009-01 2 National foreword This standard has been prepared by Technical Committee ISO/TC 213 “Dimensional and geometrical product specifications and verification”, Working Group WG 10 “Coordinate measuring machines” with intensive German participation. The

5、 responsible German body involved in its preparation was the Normenausschuss Technische Grundlagen (Fundamental Technical Standards Committee). This International Standard is based on two research projects sponsored by the European Commission with the aim of developing a method of assessing the qual

6、ity and suitability of evaluation software for coordinate measuring machines (CMM). Both projects were carried out at the Physikalisch-Technische Bundesanstalt (PTB) the German national metrology institute in Braunschweig; one of the projects involved the participation of British metrology institute

7、, the National Physical laboratory (NPL). The software tests were developed on the basis of synthetically generated data sets for various geometric elements such as the line, plane, circle and cylinder. Because experts recognized the need for a certification of CMM software by neutral and competent

8、recognized certification bodies, this standard was developed on the basis of a German proposal submitted to ISO/TC 213/WG 10 “Coordinate measuring machines”, which was in turn based on the results of the two projects mentioned above. The standard also incorporates experience gained in the use of the

9、se software tests, as well as the ideas and knowledge of experts from other ISO member countries. In 1992, CEN/TC 290 “Dimensional and geometrical product specification and verification” had already decided not to publish its own standards, but rather strongly recommended that its members be activel

10、y involved in drawing up the relevant GPS standards at ISO so that the ISO Standards could be adopted, unchanged, as European Standards. Technical Corrigendum EN ISO 10360-6:2001/AC:2008 has been integrated in this standard. The corrections are marked by a vertical line in the left margin. The DIN S

41、1:2007 has been approved by CEN as a European Corrigendum without Introduction This part of ISO 10360 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO/TR 14638). It influences link 5 of the chains of standards on size, distance, radius, a

42、ngle, form, orientation, location, run-out and datums. For more detailed information of the relation of this part of ISO 10360 to other standards and the GPS matrix model see annex B. Coordinate measurement technology is widely used in industrial metrology to assess features of a workpiece. A common

43、 requirement is to fit an associated feature to a data set consisting of coordinate measurements of a real feature. This fitting is carried out by software. Software for calculating an associated feature provides values of parameters of the associated feature that are descriptive of the size, shape,

44、 location and orientation of the feature. These parameters are useful for the purpose of carrying out calculations involving the feature, often in conjunction with other associated features and other information, and in determining the extent to which a workpiece satisfies dimensional and positional

45、 specifications. The reliability of information about features that is determined from associated features is influenced by the quality of the software for computing these features. The tests defined in this part of ISO 10360 are concerned with assessing the correctness of the parameters of computed

46、 associated features as measured by a coordinate measuring machine (CMM) or other coordinate measuring system. Although different criteria may be used to compute associated features, for example, by minimizing the Euclidean or Chebyshev norm of residuals, this test is applicable for software designe

47、d for unconstrained Gaussian (least-squares) features. In the case of reverification tests of CMMs, the software test of this part of ISO 10360 usually does not provide new or different information in comparison with that obtained by an acceptance test, since software is supposed to be stable over t

48、ime. However, a reverification test of the software may be useful following possible corruption or alteration of the software under test. For software already in existence, the evaluation of the performance may not be obtained only by fulfilling the requirements of this part of ISO 10360. However, s

49、uch cases do not necessarily exclude the ability of the software to perform correct computation of measurements. This part of ISO 10360 is applicable to software submitted for test in respect of the values it provides for the parameters of an associated feature. The test procedure is based on applying the software under test to reference data sets, and comparing the results obtained with reference results. 4
