The work of preparing International Standards is normally carried out through ISO
12、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 clo
13、sely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria
14、needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of pate

19、and reciprocating table.The primary function of such machines is to provide flat surfaces on workpieces. This International Standard specifies the tests to verify the geometric accuracy of the machine to achieve this primary function. For example, the test to check the straightness of the column mov
20、ement (Y-axis) in the horizontal XY-plane (EXY) is removed from ISO 1985:1998, since it is not directly correlated to this primary function.Positioning repeatability test for automatic mode (Not NC) is introduced. References to ISO 230-1 are revised and referred to 2012 edition. ISO 2015 All rights
21、reserved vBS ISO 1985:2015BS ISO 1985:2015Machine tools Test conditions for surface grinding machines with vertical grinding wheel spindle and reciprocating table Testing of the accuracy1 ScopeThis International Standard specifies, with reference to ISO 230-1 and ISO 230-7, both geometric and machin
22、ing tests on general purpose, normal accuracy, manually, and numerically controlled (NC) surface grinding machines with reciprocating table and vertical grinding wheel spindle. It also specifies the applicable tolerances corresponding to the above-mentioned tests.This International Standard is not a
23、pplicable to surface grinding machines with fixed or rotating tables or to machines having longitudinal traverse of the wheelhead.This International Standard deals only with the verification of the geometric accuracy of the machine. It does not apply to the testing of the machine operation (vibratio
24、ns, abnormal noises, stick-slip motion of components, etc.), nor to the checking of its characteristics (such as speeds, feeds, etc.), which should generally be checked before testing the accuracy. This International Standard provides the terminology used for the principal components of the machine
25、and the designation of the axes with reference to ISO 841:2001.NOTE In addition to the terms used in the official ISO languages (English and French), this International Standard gives the equivalent terms in the German, Italian, Persian, and Japanese languages in Annex B; these are published under t
26、he responsibility of the national member bodies for Germany (DIN), Italy (UNI), Iran (ISIRI), and Japan (JISC). However, only the terms given in the official language can be considered as ISO terms.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this

32、olerances are expressed in millimetres; angular dimensions are expressed in degrees; angular deviations and the corresponding tolerances are expressed primarily in ratios, but in some cases, microradians or arcseconds can be used for clarification purposes. Formula (1) should be used for conversion
33、of angular or tolerances.0,010/1 000 = 10 10-6= 10 rad 2 (1)4.2 Reference to ISO 230-1, ISO 230-2, and ISO 230-7For application of this International Standard, reference shall be made to ISO 230-1 and to ISO 230-7, especially for the installation of the machine before testing, warming up of the spin
34、dles and other moving parts, the description of measuring methods, and recommended accuracy of testing equipment.In the “Observations” block of tests described in Clause 5, the instructions are preceded by a reference to the corresponding clause/subclause in ISO 230-1 in cases where the test concern
35、ed is in compliance with the specifications. Similarly, for tests described in Annex A, the instructions are preceded by a reference to the corresponding clause/subclause in ISO 230-2 and ISO 230-7, respectively. Tolerances are given for each geometric test (see G1 to G12).4.3 Machine levellingPrior
36、 to conducting tests on a machine, the machine should be levelled according to the recommendations of the manufacturer/supplier (see ISO 230-1:2012, 6.1.2).4.4 Testing sequenceThe sequence in which the geometrics tests are given in no way defines the practical order of testing. In order to make the
37、mounting of instruments or gauging easier, tests can be performed in any order.4.5 Tests to be performedWhen testing a machine, it is not always necessary or possible to carry out all the tests given in this International Standard. When the tests are required for acceptance purposes, the choice of t
38、ests relating to the components and/or the properties of the machine of interest is at the discretion of the user, in agreement with the manufacturer/supplier. The tests to be used are to be clearly stated when ordering a machine. A mere reference to this International Standard for the acceptance te
39、sts, without specifying the tests to be carried out, and without agreement on the relevant expenses, cannot be considered as binding for any contracting parties.4.6 Measuring instrumentsThe measuring instruments indicated in the tests described in Clause 5 are examples only. Other instruments measur
40、ing the same quantities and having the same or smaller measurement uncertainty can be used. Reference shall be made to ISO 230-1:2012, Clause 5, which indicates the relationship between measurement uncertainties and the tolerances.4.7 DiagramsFor reasons of simplification, the figures in Clause 5 an
41、d Annex A illustrate only one type of machine. ISO 2015 All rights reserved 3BS ISO 1985:2015ISO 1985:2015(E)4.8 Software compensationWhen built-in software facilities are available for compensating geometric, positioning contouring and/or thermal deviations, their use during these tests shall be ba
42、sed on agreement between the manufacturer/supplier and user, with due consideration to the machine tool intended use.When the software compensation is used, this shall be stated in the test reports.It shall be noted that when software compensation is used, axes shall not be locked for test purposes.
43、4.9 Minimum toleranceWhen the tolerance for a geometric test is established for a measuring length different from that given in this International Standard, the tolerance can be determined by means of the law of proportionality (see ISO 230-1:2012, 4.1.2). It shall be taken into consideration that t
44、he minimum value of tolerance is 0,005 mm.4.10 Machining testMachining tests shall be made under finishing conditions.4 ISO 2015 All rights reservedBS ISO 1985:2015ISO 1985:2015(E)5 Geometric tests5.1 Linear axesObject G1Checking of straightness of the table movement (X-axis)a) in the vertical ZX-pl
