The work of preparing International Standards is normally carried

12、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

13、collaborates closely 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 ap

14、proval criteria 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

15、 subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any

18、1090-1:1998), which has been technically revised.ISO 11090 consists of the following parts, under the general title Test conditions for die sinking electro-discharge machines (die sinking EDM) Testing of the accuracy: Part 1: Single-column machines (cross-slide table type and fixed table type) Part

19、2: Double-column machines (slide-head type)iv ISO 2014 All rights reservedBS ISO 11090-1:2014ISO 11090-1:2014(E)IntroductionThe purpose of this part of ISO 11090 is to standardize methods of testing normal accuracy and general-purpose die sinking electro-discharge machines (die sinking EDM).In this

20、part of ISO 11090, the tolerances for G1, G2, G3, G4, G5, G14, P1, P2, P3, and P4 have been changed from those in ISO 11090-1:1998. The following tests in ISO 11090-1:1998 are deleted due to the limited availability of the reference T-slot in typical machines in todays market: G9 (Checking of straig

21、htness of the reference T-slot or reference surface of the table) and G10 (Checking of parallelism between the reference T-slot or reference surface of the table and the x-axis motion).

22、rge machines (die sinking EDM) Testing of the accuracy Part 1: Single-column machines (cross-slide table type and fixed-table type)1 ScopeThis part of ISO 11090 specifies, with reference to ISO 230-1 and ISO 230-2, geometric and machining tests and tests for checking accuracy and repeatability of nu

23、merically controlled positioning axes for normal accuracy and general-purpose die sinking electro-discharge machines (die sinking EDM). It also specifies the applicable tolerances corresponding to the above-mentioned tests.This part of ISO 11090 is also applicable to single-column machines of cross-

24、slide table type and fixed table type.This part of ISO 11090 deals only with the verification of accuracy of the machine. It does not apply to the testing of the machine operation (vibrations, abnormal noises, stick-slip motion of components, etc.) or to the checking of its characteristics (such as

25、speeds, feeds, etc.), which should generally be checked before the testing of the accuracy.This part of ISO 11090 provides the terminology used for the principal components of the machine and the designation of the axes with reference to ISO 841:2001.NOTE In addition to the terms used in the officia

26、l ISO languages (English and French), Annex A of this part of ISO 11090 gives the equivalent terms in the Dutch, German, Italian, Swedish, Persian, and Japanese languages. These are published under the responsibility of the national member bodies for Netherlands (NEN), Germany (DIN), Italy (UNI), Sw

27、eden (SIS), Iran (ISIRI), and Japan (JISC). However, only the terms given in the official languages can be considered as ISO terms.2 Normative referencesThe following referenced documents, in whole or in part, are normatively referenced in this document and are indispensable for the application of t

37、1090, all linear dimensions, deviations, and corresponding tolerances are expressed in millimetres, angular dimensions are expressed in degrees, and angular deviations and the corresponding tolerances are expressed primarily in ratios, but in some cases, microradians or arcseconds can be used for cl

38、arification purposes. The following expression should be used for the conversion of angular deviations or tolerances:0 010 1000 10 10 10 26,/ = =rad (1)5.2 Reference to ISO 230-1For the application of this part of ISO 11090, reference shall be made to ISO 230-1 especially for the installation of the

39、 machine before testing, warming up of the spindle and other moving parts, the description of measuring methods, and recommended accuracy of testing equipment.In the “Observations” block of the tests described in Clauses 6, 7, and 8, the instructions are preceded by a reference to the corresponding

40、clause/subclause in ISO 230-1 in cases where the test concerned is in compliance with the specifications. Tolerances are given for each geometric test (see G1 to G12).5.3 Machine levellingPrior to conducting tests on a machine, the machine should be levelled according to the recommendations of the m

41、anufacturer/supplier (see ISO 230-1:2012, 6.1.2).5.4 Testing sequenceThe sequence in which the geometric tests are given in no way defines the practical order of testing. In order to make the mounting of instruments or gauging easier, the tests may be performed in any order.5.5 Tests to be performed

42、When testing a machine tool, it is not always necessary or possible to carry out all the tests given in this part of ISO 11090. When the tests are required for acceptance purposes, the choice of tests relating to the components and/or the properties of the machine of interest is at the discretion of

43、 the user, in agreement with the manufacturer/supplier. The tests to be used are to be clearly stated when ordering a machine tool. A mere reference to this part of ISO 11090 for the acceptance tests, without specifying the tests to be carried out and without agreement on the relevant expenses, cann

44、ot be considered as binding for any contracting parties.Table 2 (continued)4 ISO 2014 All rights reservedBS ISO 11090-1:2014ISO 11090-1:2014(E)5.6 Measuring instrumentsThe measuring instruments indicated in the tests described in Clauses 6 to 8 are examples only. Other instruments measuring the same

45、 quantities and having the same or smaller measurement uncertainty can be used.5.7 Software compensationWhen built-in software facilities are available for compensating geometric, positioning, contouring, and/or thermal deviations, their use during these tests shall be based on agreement between the

46、 manufacturer/supplier and the user with due consideration to the machine tools 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.5.8 Minimum toleranceWhe

47、n the tolerance for a geometric test is established for a measuring length different from that given in this part of ISO 11090, 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 the minimum value of tolerance

48、 is 0,005 mm.5.9 Machining testMachining test shall be made under finishing conditions.5.10 Positioning tests and reference to ISO 230-2Tests P1 to P4 are applied only to numerically controlled electro-discharge machines.To apply these tests, reference shall be made to ISO 230-2, especially for the

49、environmental conditions, warming up of the machine, measuring methods, evaluation, and interpretation of the results.Checking of the W-axis is not included because the W movement is used for adjusting the head position. When required, it shall be done in the same way as the checking of the Z-axis.
