The work of preparing International Standards is normally carried out through
24、ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates
25、 closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are 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.
26、 Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this

28、second edition (2001) which has been technically revised.

35、Renishaw, PLC ix 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, angle, form, orientation, location, run-out and da
36、tums. For more detailed information of the relation of this part of ISO 10360 to other standards and the GPS matrix model see Annex F. The tests of this part of ISO 10360-2 have three technical objectives, 1) to test the error of indication of a calibrated test length using a probing system without
37、any ram axis stylus tip offset, 2) to test the error of indication of a calibrated test length using a probing system with a specified ram axis stylus tip offset, and 3) to test the repeatability of measuring a calibrated test length. The benefits of these tests are that the measured result has a di
38、rect traceability to the unit length, the meter, and that it gives information on how the CMM will perform on similar length measurements. Clause 3 in this part of ISO 10360 contains definitions that supersede similar definitions in ISO 10360-1:2000. The revised definitions are required to avoid an
39、ambiguity that would otherwise have been introduced with this issue of ISO 10360-2. Also, definition 3.6 supersedes effectively an identical definition in ISO 10360-1:2000, because the symbols used have been revised and expanded for clarification. Informative The ASME B89.4.10360.2 Technical Report
40、does not include the ISO GPS matrix; for informationon this topic see the appropriate ISO documents for this material. Informative Definitions that are specific to the ASME B89.4.10360.2 Report are included in bordered textboxes. Informative Within the ISO 10360-2 text, a comma is used to represent
41、a decimal. For example, 0,5 would bethe decimal form of . Similarly, the ISO 10360-2 text contains spellings that are different fromAmerican English usage (e.g., artefact). These are left unchanged in this Report. x INTENTIONALLY LEFT BLANK ASME B89.4.10360.2-2008 1 Geometrical Product Specification
42、s (GPS) Acceptance and reverification tests for coordinate measuring machines (CMM) Part 2: CMMs used for measuring linear dimensions 1 Scope This part of ISO 10360 specifies the acceptance tests for verifying the performance of a CMM used for measuring linear dimensions as stated by the manufacture
43、r. It also specifies the reverification tests that enable the user to periodically reverify the performance of the CMM. The acceptance and reverification tests given in this part of ISO 10360 are applicable only to Cartesian CMMs using contacting probing systems of any type operating in the discrete
44、-point probing mode. This International Standard does not explicitly apply to: non-cartesian CMMs, however, the parties may apply this part of 10360 to non-Cartesian CMMs by mutual agreement, CMMs using optical probing, however, the parties may apply this approach to optical CMMs by mutual agreement
45、. This International Standard 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 acc
46、eptance and reverification tests can be used. Informative For information on non-Cartesian CMMs, see ASME B89.4.22 regarding articulating arm CMMsand ASME B89.4.19 for laser trackers. Informative ASME B89.4.10360.2 provides a well defined set of specifications for a CMM manufacturer todescribe their
47、 CMM performance and for users to verify the specified performance. This Reportdoes not mandate testing (by either the manufacturer or the user) to verify CMM performance.The amount of testing, and which party will bear the cost of testing, is a business decision andmust be negotiated between the tw
48、o parties. ASME B89.4.10360.2-2008 2 2 Normative references The following referenced documents are indispensable for the application of this document.
