12、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 represented on that committee. International organizations, go
13、vernmental 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 drafted in accordance with the rules given in the ISO/IE
14、C Directives, Part 3. 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
15、the elements of this part of ISO 1984 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

19、 part of ISO 1984 specifies, with reference to ISO 230-1, both geometric and machining tests on general purpose and normal-accuracy milling machines with table of fixed height and with a vertical spindle. It also specifies the applicable tolerances corresponding to the above-mentioned tests. This pa
20、rt of ISO 1984 deals only with the verification of the geometric accuracy of the machine. It does not apply to the testing of the machine operation (vibrations, abnormal noises, stick-slip motion of components, etc.), nor to checking of its characteristics (speeds, feeds, etc.), which should general
21、ly be checked before testing the accuracy. This part of ISO 1984 defines the terminology used for the principal elements of the machine and indicates the designation of axes in accordance with ISO 8411. NOTENumerically controlled milling machines are covered by ISO 10791-22. 2Normative reference The
22、 following normative document contains provisions which, through reference in this text, constitute provisions of this part of ISO 1984. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 1
23、984 are encouraged to investigate the possibility 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 Stan

29、e expressed in millimetres; angular dimensions are expressed in degrees, and angular deviations and the corresponding tolerances are expressed in ratios as the primary method, but in some cases microradians or arc seconds may be used for clarification purposes. The equivalence of the following expre
30、ssions should always be kept in mind: 0,010/1000 = 10?rad?2 4.2References to ISO 230-1 To apply this part of ISO 1984, reference shall be made to ISO 230-1, especially for the installation of the machine before testing, warming up of the spindle and other moving components, description of measuring
31、methods and recommended accuracy of testing equipment. In the “Observations” block of the tests described in clauses 5 and 6, the instructions are 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.
32、 4.3Testing sequence The sequence in which the tests are presented in this part of ISO 1984 in no way defines the practical order of testing. In order to make the mounting of instruments or gauging easier, tests may be performed in any order. 4.4Tests to be performed When testing a machine, it is no
33、t always necessary nor possible to carry out all the tests described in this part of ISO 1984. When the tests are required for acceptance 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
34、 which are of interest. These tests are to be clearly stated when ordering a machine. 4.5Measuring instruments The measuring instruments indicated in the tests described in clauses 5 and 6 are examples only. Other instruments measuring the same quantities and having at least the same accuracy may be
35、 used. Dial gauges shall have a resolution of 0,001 mm.
