The work o
14、f 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 and non-governmenta
15、l, 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
16、Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 6155 was prepared by Technical Committee ISO/TC 39, Machine tools, Subcommittee SC 2, Test conditions for metal cutting machine tools. This first edition of ISO
17、 6155 cancels and replaces ISO 6155-1:1981 and ISO 6155-2:1986 which have been combined in this technical revision. Annex A of this International Standard is for information only.

Nevertheless, there is no Stan
19、dard available for machines that represent current technology. Therefore, ISO/TC 39/SC2 responded to the request for revision of this Standard by combining ISO 6155-1 and ISO 6155-2 into a single standard and adding positioning tests. 1 Scope This International Standard describes, with reference to
20、ISO 230-1 and ISO 230-2, geometric tests, machining tests and tests for accuracy and repeatability of numerically-controlled positioning axes on general purpose and normal accuracy turret and single spindle automatic lathes. It also specifies the applicable tolerances corresponding to the above-ment
21、ioned tests. This International Standard applies only to lathes with a multi-tool turret. This turret can be manually indexed, semi-automatically indexed by motion of the turret slide or automatically indexed by an independent control including numerical control. Lathes with sliding headstock are ex
22、cluded from the scope, but lathes with numerical control are included as far as the contents of this International Standard are applicable. This International Standard deals only with the verification of accuracy of the machine. It does not apply to the operational testing of the machine (vibration,
23、 abnormal noise, stick-slip motion of components, etc.) nor to machine characteristics (such as speeds, feeds, etc.) as such checks are generally carried out before testing the accuracy. 2 Normative references The following standards contain provisions which, through reference in this text, constitu
24、te provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the

The most common types of conf
32、igurations are designated types A, B, C (see Figure 7) and D and are described below. turret type A circular or multi-sided turret whose axis of rotation intersects the work spindle axis. Whether or not the turret axis is perpendicular to the work spindle axis, the axis of each turret bore must alig
33、n with the work spindle axis in its working position. Tools may be located in the bore or recess, attached to the flat turret face or located and clamped in the bore itself turret type B multi-sided turret whose axis of rotation does not intersect the work spindle axis but is parallel or at a right
34、angle to it. Special toolholders mounted and located on the turret sides (faces) are required turret type C circular (drum or disc type) turret whose axis of rotation is parallel to the work spindle axis. Tools are located in turret bores, which are parallel to the turret axis, and the turret axis i
35、s arranged so that the work spindle axis aligns with the axes of the turret bores in their working positions turret type D linear turret where tools are set on the cross slide. The necessary tool comes to the working position by the cross slide linear movement (see Figure 6) Figure 6 Linear turret l

37、8 BSI 06-19999 4 Machine size range The machines are classified into three ranges, on the basis of the criteria indicated in Table 1. Table 1 Criteria and ranges 5 Preliminary remarks 5.1 Measuring units In this International Standard, all linear dimensions, deviations and corresponding tolerances a
38、re expressed in millimeters; angular dimensions are expressed in 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
39、 kept in mind. 0,010/1 000 = 10 106 = 10 4rad . 2 5.2 Reference to ISO 230-1 To apply this International Standard, reference shall be made to ISO 230-1, especially for the installation of the machine before testing, warming up of the spindle and other moving components, description of measuring meth
40、ods and recommended accuracy of testing equipment. In the “Observations” block of the tests described in the following sections, 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 that pa
41、rt of ISO 230. 5.3 Testing sequence The sequence in which the tests are presented in this International Standard 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. 5.4 Tests to be performed When testi
42、ng a machine, it is not always necessary or possible to carry out all the tests described in this International Standard. 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 th
43、e properties of the machine which are of interest. These tests are to be clearly stated when ordering a machine. Mere reference to this International Standard for the acceptance tests, without specifying the tests to be carried out, and without agreement on the relevant expenses, can not be consider
44、ed as binding for any contracting party. 5.5 Measuring instruments The measuring instruments indicated in the tests described in the following sections are examples only. Other instruments measuring the same quantities and having at least the same accuracy may be used. Dial gauges shall have a resol
45、ution of 0,001 millimeters or better. 5.6 Machining tests Machining tests shall be made with finishing cuts only, not with roughing cuts which are liable to generate appreciable cutting forces. 5.7 Machine levelling Prior to conducting tests on a machine, the, machine should be levelled according to
46、 the recommendations of the supplier/manufacturer. (See 3.11 of ISO 230-1:1996.)
