14、tional 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 represented on that committee. Intern

15、ational 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 are drafted in accordance with the

16、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 International Standard requires approval by

17、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 13041-7 was prepared by Technical Committee IS

18、O/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 tests for machines with a horizontal workh

19、olding 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 of feeds, speeds and interpolations Part

20、6: Accuracy of a finished test piece Part 7: Evaluation of contouring performance in the coordinate planes Part 8: Evaluation of thermal distortions BSISO130417:2004IS-14031 O7:(4002E) iv I SO 4002 All irthgs ersedevrIntroduction The object of ISO 13041 is to supply information as wide and comprehen

21、sive 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 machine tools, tests for turning centres and n

22、umerically 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 normal-accuracy turning centres and numerica

23、lly controlled turning machines. BSISO130417:2004INTENRATIONAL TSANDADR IS-14031 O7:(4002E)I SO 4002 All irthgs ersedevr 1Test conditions for numerically controlled turning machines and turning centres Part 7: Evaluation of contouring performance in the coordinate planes 1 Scope This part of the ISO

24、 13041 describes a method of checking the contouring performance of turning centres (or numerically controlled turning) by conducting circular tests and by evaluating the radial deviation F and circular deviation G, in accordance with ISO 230-4. NOTE Measurements of circular movements can be carried

25、 out by different methods as described in Clause 6.6 of ISO 230-1:1996. These methods consist of using a rotating one-dimensional probe and a test mandrel, a circular masterpiece and a two-dimensional probe, or a telescoping ball bar. Other test methods may be applied if the accuracy of the equipmen

26、t is the same as (or better than) the accuracy of the methods described. Influences of typical machine deviations on circular paths are shown in Annex B of ISO 230-4:1996. The concept of checks by circular tests described in this part of ISO 13041 is to verify the circular movement only in one posit

27、ion per coordinate plane of the machine, at only one feed rate, and to repeat the test once in the opposite contouring direction. The purpose of this part of ISO 13041 is not to provide a means of analysing the causes for the measured circular deviations, but to offer the user a method for periodic

28、checking of the machine tool. It is recommended to carry out the tests of this part of ISO 13041 after the machine tool has passed the acceptance tests and to use these results as a basis for comparison during periodic checks. Therefore acceptable deviations from the initial results have to be decid

29、ed by the user. If the tests are used for machine acceptance purposes, the supplier/manufacturer and the user have to agree on specific diameters, feed rates and tolerances for the tests. NOTE ISO 13041-5, which deals with the accuracy of feeds, speeds and interpolations, also includes as test K4 a

30、circular test. There the aim is to check the mutual behaviour of two linear axes (generally X and Y) at two defined feed rates for one defined diameter. This is more or less a diagnostic test with respect to the circular interpolation, whereas the circular tests of this part of ISO 13041 give inform

31、ation on the overall contouring performance of the machine. 2 Normative references The following referenced documents are indispensable for the application of this document.

34、3041-1 apply. 4 Preliminary remarks 4.1 Reference to ISO 230-1 and ISO 230-4 To apply this part of ISO 13041, reference shall be made to ISO 230-1 and ISO 230-4, especially for the installation of the machine before testing, warming up of the machine, description of measuring methods, evaluation, as

35、 well as for the recommended accuracy of the testing equipment and presentation of the results. 4.2 Testing sequence The circular tests shall be carried out in the XZ plane and, if applicable, in the other coordinate planes (e.g. XY plane, YZ plane, X2Z2 plane and Y2Z2 plane). The sequence in which

36、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 gauging easier, tests may be performed in any order. 4.3 Tests to be performed When testing a machine, it is not always necessary or possible to carry o

37、ut 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 with the supplier/manufacturer; those tests relating to the components and/or the properties of the machine which are of interest. These tests are t

38、o 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 out, and without agreement on the relevant expenses, cannot be considered as binding for any contracting party. 4.4 Position of linear axes not u

39、nder test During the check of contouring performance, those of the three basic linear axes not involved in the test shall be kept as far as possible in the middle of their working displacement, or otherwise in a position such as to minimize deflections of elements affecting measurements. Sliding spi

40、ndles, etc., when they are supplementary axes, shall be kept retracted. 4.5 Measuring Instruments In accordance with 6.63 of ISO 230-1:1996, i.e. rotating one-dimensional probe, or circular masterpiece and two-dimensional probe or telescoping ball bar. For the checking of radial deviation, the refer

41、ence dimension of the test instrument shall be known. 4.6 Presentation of results Table 1 provides an example of the format for the presentation of the results, and a graphical presentation of the results should be provided as specified in ISO 230-4.
