The work of preparing International Standards is normally carried out through

15、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, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates

16、 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/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards.

17、 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 the elements of this

18、document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 13041-3 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 follo

19、wing parts, under the general title Test conditions for numerically controlled turning machines and turning centres: Part 1: Geometric tests for machines with a horizontal workholding spindle Part 2: Geometric tests for machines with a vertical workholding spindle Part 3: Geometric tests for machine

20、s with inverted vertical workholding spindles Part 4: Accuracy and repeatability of positioning of linear and rotary axes Part 5: Accuracy 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: Evalu

22、3:2008 specifies, with reference to ISO 230-1 and ISO 230-7, the geometric tests on general-purpose, numerically controlled (NC) turning machines and turning centres with inverted vertical workholding spindles, as well as the corresponding applicable tolerances. This part of ISO 13041 presents the d

23、ifferent concepts or configurations and common features of NC turning machines and turning centres with inverted vertical spindles. It also provides a terminology and designation of controlled axes. (See Figures 1, 2, 3 and 4.) This part of ISO 13041 deals only with the verification of the accuracy

24、of the machine. It does not apply to the operational testing of the machine (e.g. vibration, abnormal noise, stick-slip motion of components), nor to machine characteristics (e.g. speeds, feeds), as such checks are generally carried out before testing accuracy. 2 Normative references The following r

25、eferenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 230-1:1996, Test code for machine tools Part 1: Geometric ac

30、driven tool(s) and the capacity to orientate the work-holding spindle around its axis. NOTE It can include additional features such as automatic tool changing from a turret and/or magazine. 3.7 numerically controlled turning machine with inverted vertical workholding spindle NC turning machine with

31、 inverted vertical workholding spindle NC turning machine where the workpiece is mounted on an inverted vertical workholding spindle equipped with a workholding device at the lower end of the workholding spindle. NOTE For other types of vertical workholding spindle machine, see ISO 13041-2. 3.8 turn

NOTE 1 It can include additional features such as automatic tool changing from a magazine or Y

33、axis motion. NOTE 2 For other types of vertical workholding spindle turning centre, see ISO 13041-2. 4 Preliminary remarks 4.1 Measuring units In this part of ISO 13041, all linear dimensions, deviations and corresponding tolerances are expressed in millimetres, angular dimensions are expressed in

34、degrees, and angular deviations and the corresponding tolerances are expressed 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 = 10 106= 10 rad 2 arcsec BS ISO 1304

35、1-3:2009ISO 13041-3:2009(E) ISO 2009 All rights reserved 34.2 Reference to ISO 230-1 and ISO 230-7 For application of this part of ISO 13041, reference shall be made to ISO 230-1 or ISO 230-7, especially for the installation of the machine before testing, warming-up of spindles and other moving part

36、s, the description of measuring methods, and recommended accuracy of testing equipment. In the “Observations” block of tests described in Clauses 5 and 6, the instructions are preceded by a reference to the corresponding clause/subclause in ISO 230-1 and/or ISO 230-7 in cases where the test concerne

37、d is in compliance with their specifications. Tolerances are given for each geometric test (see G1 to G20). 4.3 Machine levelling Prior to conducting tests on a machine, the machine should be levelled according to the recommendations of the supplier/manufacturer (see ISO 230-1:1996, 3.11). 4.4 Testi

38、ng sequence The sequence in which the geometric tests are given 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. 4.5 Tests to be performed When testing a machine, it is not always necessary or possi

39、ble to carry out all the tests given in this part of ISO 13041. When the tests are required for acceptance purposes, the choice of tests relating to the components and/or the properties of the machine of interest is at the discretion of the user, in agreement with the supplier/manufacturer. The test

40、s to be used are to be clearly stated when ordering a machine. A mere reference to this part of ISO 13041 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. 4.6 Measuring

41、 instruments The measuring instruments indicated in relation to the tests given in Clauses 5 and 6 are examples only. Other instruments measuring the same quantities and having at least the same measurement uncertainty and the same resolution may be used. Linear displacement sensors shall have a res

42、olution of 0,001 mm or better. 4.7 Diagrams For reasons of simplification, the figures in Clauses 5 and 6 of this part of ISO 13041 illustrate only one type of machine. 4.8 Software compensation When built-in software facilities are available for compensating geometric, positioning, contouring and t

43、hermal deviations, their use during these tests should be based on agreement between the user and the supplier/manufacturer. When the software compensation is used, this shall be stated in the test reports. 4.9 Minimum tolerance When the tolerance for a geometric test is established for a measuring

44、length different from that given in this part of ISO 13041 (see ISO 230-1:1996, 2.311), it shall be taken into consideration that the minimum value of tolerance is 0,005 mm. 4.10 Machine classifications, descriptions, terminology and designation of axes The machines considered in this part of ISO 13

45、041 are divided into three basic configurations, as shown in Figure 1.
