3、tted without license from IHS -,-,- Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body i
4、nterested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical com
5、mittees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. International Standard IS0 7945 was prepared by Technical
6、Committee ISO/TC 39, Machine tools. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated. 0 international Organization for Standardization, 1987

8、48 : 1987 (EI Woodworking machines - Routing machines - Nomenclature and acceptance conditions 1 Scope and field of application This International Standard specifies the nomenclature ap- propriate to each part of the machine and, with reference to IS0 230-1, the geometrical tests for routing machine
9、s, and gives the corresponding permissible deviations which apply to machines of general purpose use and normal accuracy. NOTE - In addition to terms used in the three official IS0 languages (English, French and Russian), this International Standard gives the equivalent terms in the German, Spanish,
10、 Italian and Swedish languages in an annex; these have been included at the request of Technical Committee ISO/TC 39 and are published under the responsi- bility of the member bodies for Germany, F.R. (DIN), Spain (IRANOR), Italy WNI) and Sweden (SIS). However, only the terms given in the official l
11、anguages can be considered as IS0 terms. This International Standard deals only with the verification of the accuracy of the machine. It does not apply to the testing of the running of the machine (vibrations, abnormal noises, stick- slip motion of the components, etc.), nor to its characteristics (
12、speeds, feeds, etc.) which should generally be checked before the accuracy is tested. This International Standard does not impose any practical test. For routing machines, practical tests are an exception and need be performed only where there is prior agreement between the manufacturer and the user
13、. This International Standard applies to those machines designated by the number 12.315.12 in IS0 7994. The annex does not form an integral part of this International Standard. IS0 7984, Woodworking machines - Technical classification of woodworking machines and auxiliary machines for wood- working.
14、 3 Preliminary remarks 3.1 In this International Standard all dimensions and permiss- ible deviations are expressed in millimetres. 3.2 To apply this International Standard, reference should be made to IS0 230-1, especially for installation of the machine before testing, the warming up of the main s
15、pindle and other moving parts, and the description of the measuring methods. The measuring instruments shall not permit measurement errors over 1 I3 of the checked tolerances. 3.3 The sequence in which the geometrical tests are given is related to the sub-assemblies of the machine, and this in no wa
16、y defines the practical order of testing. In order to make mounting of instruments and gauging easier, tests may be applied in any order. 3.4 When inspecting a machine, it is not always possible or necessary to carry out all the tests given in this International Standard. 3.5 It is up to the user to
17、 choose, in agreement with the manufacturer, those tests relating to the properties which are of interest to him, but these tests shall be clearly stated when ordering a machine. 3.6 A movement is longitudinal when it takes place in the working direction of the piece. 2 References IS0 230-1, Accepta
18、nce code for machine tools - Part I: Geometric accuracy of machines operating under no-load or finishing conditions. 3.7 When establishing the tolerance for a measuring range different from that given in this International Standard (see subclause 2.311 in IS0 230-I), it should be taken into con- sid
