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 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 rules given in the ISO/IEC Directives, Part 3. 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 part of ISO 3686 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. InternationalStandardISO 3686-1waspreparedbyTechnicalCommitteeISO/TC 39,Machinetools, Subcommittee SC 2, Test conditions for metal cutting machine tools. This first edition of ISO 3686-1, together with ISO 3686-2, cancel and replace ISO 3686:1976, of which they constitute a technical revision. ISO 3686 consists of the following parts, under the general title Test conditions for high accuracy turret and single spindle coordinate drilling and boring machines with table of fixed height with vertical spindle Testing of the accuracy: ?Part 1: Single column type machines ?Part 2: Portal type machines with moving table Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/19/2007 04:04:41 MDTNo reproduction or networking permitted without license from IHS -,-,- INTERNATIONAL STANDARDISO 3686-1:2000(E) © ISO 2000 All rights reserved1 Test conditions for high accuracy turret and single spindle coordinate drilling and boring machines with table of fixed height with vertical spindle Testing of the accuracy Part 1: Single column type machines 1Scope This part of ISO 3686 specifies, with reference to ISO 230-1; both geometric tests and machining tests on vertical spindle, single column type coordinate drilling and boring machines. It also specifies the applicable tolerances corresponding to the above-mentioned tests. It should be noted that, besides drilling and boring operations, it may be possible to carry out light milling operations with these machines. However, this part of ISO 3686 does not deal with jig boring machines or machining centres. This part of ISO 3686 deals only with the verification of the accuracy of the machine. It does not apply to the testing of the machine operation (vibrations, abnormal noises, the stick-slip motion of components, etc.), nor the machine characteristics (such as speeds, feeds, etc.), which should generally be carried out before testing the accuracy. This part of ISO 3686 provides the terminology used for the principle components of the machine and indicates the designation of the axes in accordance with ISO 841. 2Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this part of ISO 3686. For dated references subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 3686 are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

The equivalence of the following expressions should be kept in mind: 0,010/1 000 = 10 ?rad ? 2'' 4.2Reference to ISO 230-1 To apply this part of ISO 3686, 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 methods and recommended accuracy of testing equipment. In the “Observations” block of the tests described in clauses 5 and 6, 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 ISO 230-1. 4.3Testing sequence The sequence in which the tests are presented in this part of ISO 3686 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. 4.4Tests to be performed When testing a machine, it is not always necessary nor possible to carry out all the tests described in this part of ISO 3686. 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 to be clearly stated when ordering a machine. It should be noted that, for turret head-drilling machines, all the geometric tests that concern the rotation of the spindle, i.e., tests G9, G10, G11 and G12, should be carried out on all spindles. 4.5Measuring instruments The measuring instruments indicated in the tests described in clauses 5 and 6 are examples only. Other instruments measuring the same quantities and having at least the same accuracy may be used. Dial gauges shall have a resolution of 0,001 mm. 4.6Minimum tolerance When the tolerance for a geometric test is established for a measuring length different from that given in this part of ISO 3686 (see 2.311 of ISO 230-1:1996), it shall be taken into consideration that the minimum value of tolerance is 0,005 mm. 4.7Machining tests Machining tests shall be made with finishing cuts only, not with roughing cuts which are liable to generate appreciable cutting forces.

If the spindle can be locked, either the dial gauge, the microscope or the interferometer may be mounted on it; if the spindle cannot be locked, the instrument shall be placed on the spindle head of the machine. The measuring line should pass as close to the centre of the table as possible.
