14、ntrolled Copy, (c) BSI ISO 14137:2000(E) iv? Foreword ISO (the International Organization for Standardization) 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 memb
15、er 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 closely with the International Ele
16、ctrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for votin
17、g. 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 International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying an
18、y or all such patent rights. International Standard ISO 14137 was prepared by Technical Committee ISO/TC 39,Machine tools, Subcommittee SC 2,Test conditions for metal cutting machine tools.

19、ERNATIONAL STANDARD?ISO 14137:2000(E) ?1 Machine tools Test conditions for wire electrical-discharge machines (wire EDM) Terminology and testing of the accuracy 1?Scope ISO 14137 specifies, with reference to ISO 230-1, ISO 230-2 and ISO 230-4, geometric tests, tests of accuracy and repeatability of
20、numerically controlled positioning axes, machining test and circular tests for general purpose, normal-accuracy wire electrical-discharge machines (wire EDM). It also specifies applicable tolerances correspond- ing to the above-mentioned tests. ISO 14137 is applicable to single column machines of cr
21、oss slide table type and double column type machines. ISO 14137 deals only with the testing of accuracy of the machine. It does not apply to the testing of the machine operation (vibration, abnormal noise, stick-slip motion of components, etc.) nor to machine characteristics (such as speeds, feeds,
22、etc.), which should generally be carried out before testing the accuracy. ISO 14137 provides the terminology used for the principle components of the machine and the designation of the axes in accordance with ISO 841. 2?Normative references The following normative documents contain provisions which,
23、 through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possib
24、ility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 230-1:1996,Test code for machine

35、137:2000(E) 4? 4?Preliminary remarks 4.1? Measuring units In this International Standard, all linear dimensions, deviations and corresponding tolerances are expressed in millimetres; angular dimensions are expressed in degrees, and angular deviations and the corresponding tolerances are expressed pr
36、imarily in ratios, but in some cases microradians or arcseconds may be used for clarification purposes. The equivalence of the following expressions should always be kept in mind: 0,010/1 000 = 10 ?rad ? 2“ 4.2? Reference to ISO 230-1 To apply this International Standard, reference shall be made to
37、ISO 230-1, especially for the installation of the machine before testing, warming up of the spindle and other moving components, description of measuring methods and recommended accuracy of testing equipment. In the “Observations” block of the tests described in clauses 5 to 8, the instructions are
38、followed by a reference to the corresponding clause in ISO 230-1, in cases where the test concerned is in compliance with the specifications of ISO 230-1. 4.3? Testing sequence The sequence in which the tests are presented in this International Standard in no way defines the practical order of testi
39、ng. In order to make the mounting of instruments or gauging easier, tests may be performed in any order. 4.4? Tests to be performed When testing a machine, it is not always necessary nor possible to carry out all the tests described in this International Standard. When the tests are required for acc
40、eptance purposes, it is up to the user to choose, in agreement with the supplier/manufacturer, those tests relating to the components and/or the properties of the machine which are of interest. These tests are to be clearly stated when ordering a machine. Mere reference to this International Standar
41、d for the acceptance tests, without specifying the tests to be carried out, and without agreement on the relevant expenses, cannot be considered as binding for any contracting party. 4.5? Measuring instruments The measuring instruments indicated in the tests described in clauses 5 to 8 are examples
42、only. Other instruments measuring the same quantities and having at least the same accuracy may be used. Dial gauges shall have a resolution of 0,001 mm or better. 4.6? Minimum tolerance When establishing the tolerance for a measuring length different from that given in this International Standard (
43、see 2.311 of ISO 230-1:1996), it shall be taken into consideration that the minimum value of tolerance is 0,005 mm. 4.7? Positioning tests and reference to ISO 230-2 Tests P1 to P5 are only applied to numerically controlled X, Y, Z, U and V axes. To apply the tests, reference should be made to ISO 2
44、30-2, especially for the environmental conditions, warming up of the machine, measuring methods, evaluation and interpretation of the results. When other numerically controlled axes exist, checking shall be agreed between the supplier/manufacturer and user. Licensed Copy: sheffieldun sheffieldun, na

Machining of other suitable test parts is also possible under the agreement between the supplier/manufactu
46、rer and user. The machining test may be substituted by circular test C1. 4.9? Circular test and reference to ISO 230-4 To apply the tests, reference should be made to ISO 230-4:1996, especially to clauses 4 and 6 for the test conditions and presentation of results. The circular test may be substitut
47、ed by machining test M1. Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 26 08:21:51 GMT+00:00 2006, Uncontrolled Copy, (c) BSI ISO 14137:2000(E) 6? 5?Geometric tests 5.1?
