16、(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 member body interested in a subject for which a technical comm
17、ittee 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 Electrotechnical Commission (IEC) on all matters of electrote
18、chnical 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 voting. Publication as an International Standard requires appro
19、val by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of 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. International Standard ISO 1984-1 w
20、as prepared by Technical Committee ISO/TC 39, Machine tools, Subcommittee SC 2, Test conditions for metal cutting machine tools. This first edition of ISO 1984-1, together with ISO 1984-2, cancels and replaces ISO 1984:1982 and ISO 1984-0:1984, of which they constitute a technical revision. ISO 1984

22、 rights rsedevre 1 Test conditions for manually controlled milling machines with table of fixed height Testing of the accuracy Part 1: Machines with horizontal spindle 1 Scope This part of ISO 1984 specifies, with reference to ISO 230-1, both geometric and machining tests on general purpose and norm
23、al-accuracy milling machines with table of fixed height and with a horizontal spindle. It also specifies the applicable tolerances corresponding to the above-mentioned tests. This part of ISO 1984 deals only with the verification of the geometric accuracy of the machine. It does not apply to the tes
24、ting of the machine operation (vibrations, abnormal noises, stick-slip motion of components, etc.), nor to the checking of its characteristics (speeds, feeds, etc.), which should generally be checked before testing accuracy. This part of ISO 1984 defines the terminology used for the principal elemen
25、ts of the machine and indicates the designation of axes in accordance with ISO 841 1 . NOTE Numerically controlled milling machines are covered by ISO 10791-1 2 . 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions o
26、f 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 1984 are encouraged to investigate the possibility of applying the most recent editions of the normative document
27、s 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.

32、ns 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 expressions should always be kept in mind: 0,010/1000 = 10 rad 2 4.2 Reference to ISO 230-1 To app
33、ly 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 methods and recommended accuracy of testing equipment. In the “Observations” block of the tes
34、ts described in clauses 5 and 6, the instructions are preceded 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 part of ISO 1984
35、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. 4.4 Tests to be performed When testing a machine, it is not always necessary nor possible to carry out all the tests described in this part of ISO 19
36、84. 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 which are of interest. These tests are to be clearly stated when ordering a machine. 4.5 M

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.ISO 1984-1:2001(E) 4 ISO 1002 All r
