24、 is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be repre

25、sented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are

26、 drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internationa

27、l Standard requires approval by at least 75 % of the member bodies casting a vote.

28、epared by Technical Committee ISO/TC 213, Dimensional and geometrical product specifications and verification. ISO 10360 consists of the following parts, under the general title Geometrical product specifications (GPS) Acceptance and reverification tests for coordinate measuring machines (CMM): Part

29、 1: Vocabulary Part 2: CMMs used for measuring linear dimensions Part 3: CMMs with the axis of a rotary table as the fourth axis Part 4: CMMs used in scanning measuring mode Part 5: CMMs using single and multiple stylus contacting probing systems Part 6: Estimation of errors in computing of Gaussian

31、O 10360 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO/TR 14638). It influences chain link 5 of the chains of standards on size, distance, radius, angle, form, orientation, location, run-out and datums. For more detailed information on

32、the relation of this part of ISO 10360 to other standards and the GPS matrix model, see Annex E. The tests of this part of ISO 10360 have two technical objectives: a) to test the error of indication of a calibrated test length using an imaging probing system; b) to test the errors in the imaging pro

33、bing system. The benefits of these tests are that the measured result has a direct traceability to the unit length, the meter, and that it gives information on how the CMM will perform on similar length measurements. The structure of this part of ISO 10360 parallels that of ISO 10360-2, which is for

34、 CMMs equipped with contact probing systems. The testing methodology between these two parts of ISO 10360 is intentionally similar. The differences that exist may be eliminated in future revisions of either this part of ISO 10360 or ISO 10360-2. All the definitions in Clause 3 will appear in the rev

35、ision of ISO 10360-1:2000.

36、is part of ISO 10360 specifies the acceptance tests for verifying the performance of a coordinate measuring machine (CMM) used for measuring linear dimensions as stated by the manufacturer. It also specifies the reverification tests that enable the user to periodically reverify the performance of th

37、e CMM. The acceptance and reverification tests given in this part of ISO 10360 are applicable only to Cartesian CMMs using imaging probing systems of any type operating in the discrete-point probing mode. This part of ISO 10360 does not explicitly apply to: non-Cartesian CMMs; however, parties may a

38、pply this part of ISO 10360 to non-Cartesian CMMs by mutual agreement; CMMs using other types of optical probing; however, parties may apply this approach to other optical CMMs by mutual agreement; CMMs using contact probing systems (see ISO 10360-2 for contact probing systems). This part of ISO 103

39、60 specifies performance requirements that can be assigned by the manufacturer or the user of a CMM, the manner of execution of the acceptance and reverification tests to demonstrate the stated requirements, rules for proving conformance, and applications for which the acceptance and reverification

40、tests can be used. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
