13、dies). 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, governmental an

14、d 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/IEC Directives,

15、 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 International Standard requires approval by at least 75 % of the member bodies cas

16、ting 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 13041-6 was prepared by Technical Committee ISO/TC 39, Machine tools, Subcommittee S

17、C 2, Test conditions for metal cutting machine tools. This second edition cancels and replaces the first edition (ISO 13041-6:2005), which has been technically revised. ISO 13041 consists of the following parts, under the general title Test conditions for numerically controlled turning machines and

18、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 machines with inverted vertical workholding spindles Part 4: Accuracy and repeatability of positioning of l

20、troduction A numerically controlled turning machine is a machine tool in which the principal motion is the rotation of the workpiece against the stationary cutting tool(s) and where cutting energy is brought by the workpiece and not by the tool. This machine is controlled by a numerical control (NC)

21、 providing automatic functioning in accordance with ISO 13041-1:2004, 3.3, and can be of single spindle or multi-spindle type. A turning centre is an NC turning machine equipped with power-driven tool(s) and the capacity to orientate the workholding spindle around its axis. This machine can include

22、additional features, such as automatic tool changing from a magazine. The objective of the ISO 13041 series is to supply as wide and comprehensive information as possible on geometric, positional, contouring, thermal and machining tests, which can be carried out for comparison, acceptance, maintenan

23、ce or any other purpose. The ISO 13041 series specifies, with reference to the relevant parts of ISO 230, tests for turning centres and numerically controlled turning machines with/without tailstocks, standing alone or integrated in flexible manufacturing systems. It also establishes the tolerances

24、or maximum acceptable values for the test results corresponding to general purpose and normal accuracy turning centres and numerically controlled turning machines.

25、ically controlled turning machines and turning centres Part 6: Accuracy of a finished test piece 1 Scope This part of ISO 13041 specifies, with reference to ISO 230-1, a series of cutting tests, under finishing conditions, of standard test pieces. It also specifies the characteristics and dimensions

26、 of the test pieces themselves. This part of ISO 13041 is intended to supply minimum requirements for assessing the cutting accuracy of the machine. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the editio

27、n 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 accuracy of machines operating under no-load or finishing conditions ISO 1101, Geometrical Product Specifications (

30、eliminary remarks 3.1 Measuring units In this part of ISO 13041, all linear dimensions, deviations and corresponding tolerances are expressed in millimetres; angular dimensions are expressed in degrees, and angular deviations and the corresponding tolerances are expressed in ratios, but in some case

31、s 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 rad 2 BS ISO 13041-6:2009ISO 13041-6:2009(E) 2 ISO 2009 All rights reserved3.2 Reference to ISO 230-1 To apply this part of ISO 13041, ref

32、erence shall be made to ISO 230-1, especially for the installation of the machine before testing, warming up of the machine, description of measuring methods, and evaluation and presentation of the results. 3.3 Test sequence The sequence in which the tests are presented in this part of ISO 13041 in

33、no way defines the practical order of testing. 3.4 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 wi

34、th 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 carried

35、 out, and without agreement on the relevant expenses, cannot be considered as binding for any contracting party. When testing machines with moving cross rail, the tolerances given in this part of ISO 13041 apply when the position of the cross rail is fixed at a certain location (preferably in mid-tr

36、avel of the cross rail or some other predetermined position subject to agreement between the supplier/manufacturer and the user). 3.5 Measuring instruments The measuring instruments indicated in the tests described in Clause 4 are examples only. Other instruments measuring the same qualities and hav

37、ing at least the same accuracy may be used. Linear displacement sensors shall have a resolution of 0,001 mm or better. See ISO 14253-1, ISO/TS 14253-2 and ISO/TR 16015. 3.6 Fixing of test pieces The test piece shall be conveniently mounted on a proper fixture or chuck, such that maximum stability of

38、 tools and fixture is achieved. The mounting surfaces of the fixture and the test piece shall be flat and/or cylindrical. It is recommended that suitable means of fixturing be used to allow for tool breakthrough (if applicable). NOTE Fixing of the test piece can have a significant impact on the resu

39、lts of the tests. Therefore, parameters associated with fixing the test piece, such as type and number of jaws, and amount of clamping force, are considered carefully. 3.7 Materials of test pieces, tooling and cutting parameters The test piece material, tooling and the subsequent cutting parameters

40、are subject to agreement between supplier/manufacturer and user, and shall be recorded. The test piece material shall be specified with proper material designations. 3.8 Sizes of test pieces If the test pieces are machined several times, with a consequent reduction of external dimensions, it is reco

41、mmended that the final test piece, when used for acceptance purposes, comply with the dimensions specified in this part of ISO 13041. If the test pieces come from previous cutting tests and are re-useable, their characteristic dimensions shall remain within 10 % of those indicated in this part of IS

42、O 13041. When the test pieces are re-used, a shallow cut shall be made to clean up all surfaces before new finishing test cuts are taken. BS ISO 13041-6:2009ISO 13041-6:2009(E) ISO 2009 All rights reserved 3It is also recommended that type and serial number of the machine, date of test and names and

43、 orientation of the axes be marked on the test pieces and that they be delivered with the machine for reference purposes. In principle, no more than one piece of each type shall be machined for acceptance purposes. In case of special requirements, such as statistical assessment of the machine perfor

44、mance, the machining of more test pieces is to be subject to agreement between the supplier/manufacturer and user. Preliminary cuts shall be taken in order to make the depth of cut as constant as possible. 3.9 Information to be recorded For tests made according to the requirements of this part of IS

45、O 13041, the following information shall be compiled as completely as possible and shall be included in the test report: a) material and dimensions of the test piece; b) material and dimensions of the tool; c) cutting speed(s); d) feedrate(s) (feed velocity); e) depth(s) of cut; f) axes used for mac

46、hining; g) test piece fixing conditions; h) other cutting parameters, e.g. cutting fluid. 3.10 Machine size categories For the purposes of the ISO 13041 series, machines are classified into size categories depending on their work spindle orientation (see ISO 13041-1 for horizontal workholding spindl

47、e, ISO 13041-2 for vertical workholding spindle, and ISO 13041-3 for inverted vertical workholding spindle). The categories and size ranges are referenced in the cutting tests of this part of ISO 13041 and are therefore repeated here for the convenience of the user. ISO 13041-1 NC turning machines a

48、nd turning centres with horizontal workholding spindle are classified into three size categories, on the basis of the criteria specified in Table 1. Table 1 Size range for machines with horizontal workholding spindle Criteria Category 1 Category 2 Category 3 Swing diameter over bed D u 250 250 5 000

49、 Diameter of workholding spindle/table D u 500 500 5 000 NOTE 3 The nominal chuck diameter is defined in ISO 3442-1 and ISO 3442-2. ISO 13041-3 NC turning machines and turning centres with inverted vertical workholding spindle are classified into three size categories, on the basis of the criteria specified in Table 3. Table 3 Size ranges for machines with inverted vertical workholding spindle Criteria Category 1 Category 2 Category 3 Nominal diameter of chuck d u 250 250 400 Maximum turning diameter D u 3
