16、on) 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 re

17、presented 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

18、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 approval by at least 75 % of the member bodies casting

19、 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 1984-2 was prepared by Technical Committee ISO/TC 39, Mac

20、hine tools, Subcommittee SC 2, Test conditions for metal cutting machine tools. This first edition of ISO 1984-2, together with ISO 1984-1, cancels and replaces ISO 1984:1982 and ISO 1984-0:1984, of which they constitute a technical revision. ISO 1984 consists of the following parts, under the gener

22、ontrolled milling machines with table of fixed height Testing of the accuracy Part 2: Machines with vertical spindle 1 Scope This 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 he

23、ight and with a vertical 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 testing of the machine operation (vibrations, abnormal n

24、oises, stick-slip motion of components, etc.), nor to checking of its characteristics (speeds, feeds, etc.), which should generally 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 ax

25、es in accordance with ISO 841 1 . NOTE Numerically controlled milling machines are covered by ISO 10791-2 2 . 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this part of ISO 1984. For dated references, subseq

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 documents indicated below. For undated references, the latest

27、 edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

31、nsions 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 expressions should always be kept in mind: 0,

33、ting 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. 4.3 Testing sequence The sequence in w

34、hich 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. 4.4 Tests to be performed When testing a machine, it is not always necessary nor possible to ca

35、rry 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 which are of interest. These tests a

36、re to be clearly stated when ordering a machine. 4.5 Measuring 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 used. Dial gauges shall have a reso
