14、dization) 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

15、 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 electrotechnical standardization. International Stan

16、dards 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Int

17、ernational 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 13041

18、-4 was prepared by Technical Committee ISO/TC 39, Machine tools, Subcommittee SC 2, Test conditions for metal cutting machine tools. ISO 13041 consists of the following parts, under the general title Test conditions for numerically controlled turning machines and turning centres: Part 1: Geometric t

19、ests for machines with a horizontal workholding spindle Part 2: Geometric tests for machines with vertical workholding spindle Part 3: Geometric tests for machines with inverted vertical workholding spindle Part 4: Accuracy and repeatability of positioning of linear and rotary axes Part 5: Accuracy

20、of feeds, speeds and interpolations Part 6: Accuracy of a finished test piece Part 7: Evaluation of contouring performance in the coordinate planes Part 8: Evaluation of thermal distortions BSISO130414:2004IS-14031 O4:(4002E) iv I SO 4002 All irthgs ersedevrIntroduction The object of ISO 13041 is to

21、 supply information as wide and comprehensive as possible on geometric, positional, contouring, thermal and machining tests which can be carried out for comparison, acceptance, maintenance or any other purpose. ISO 13041 specifies, with reference to the relevant parts of ISO 230, Test code for machi

22、ne tools, tests for turning centres and numerically controlled turning machines with/without tailstocks standing alone or integrated in flexible manufacturing systems. ISO 13041 also establishes the tolerances or maximum acceptable values for the test results corresponding to general purpose and nor

23、mal-accuracy turning centres and numerically controlled turning machines.

24、ar and rotary axes 1 Scope This part of ISO 13041 specifies, with reference to ISO 230-2, the tolerances which apply to the positioning tests for linear axes, up to 2 000 mm in length, and rotary axes of numerically controlled (NC) turning machines and turning centres. It does not deal with environm

For dated references, only the edition cited applies. For undated references, the latest ed

26、ition of the referenced document (including any amendments) applies.

29、g units In this part of ISO 13041, 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 in ratios, but in some cases microradians or arcseconds m

30、ay 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 230-2 To apply this part of ISO 13041, reference shall be made to ISO 230-2, especially for the installation of the machine before testing,

31、warming up of the machine, description of measuring methods, evaluation and presentation of the results. 4.3 Testing sequence The sequence in which the tests are presented in this part of ISO 13041 in no way defines the practical order of testing. In order to make the mounting of instruments or gaug

32、ing easier, tests may be performed in any order. 4.4 Tests to be performed When testing a machine, it is not always necessary or possible to carry out all the tests described in this part of ISO 13041. When the tests are required for acceptance purposes, it is up to the user to choose, in agreement

33、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 part of ISO 13041 for the acceptance tests, without specifying the tests to be carri

34、ed out, and without agreement on the relevant expenses, cannot be considered as binding for any contracting party. 4.5 Position of linear axes not under test During the check of an axis, those of the basic linear axes not involved in the test shall be kept as far as possible in the middle of their w

35、orking travel, or otherwise in a position such as to minimize deflections of elements affecting measurements. Sliding spindles, etc., when they are supplementary axes, shall be kept retracted. 5 Positioning of linear axes 5.1 Tolerances Table 1 gives the positioning tolerances, as defined in Clause

36、2 of ISO 230-2:1997, for NC turning machines and turning centres of normal accuracy, relating to different measurement travels up to 2 000 mm.
