19、0 Bibliography12 ENISO103603:2001iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body i

20、nterested 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 Electrotechn

21、ical 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. Public

22、ation 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 10360 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such

23、patent rights. International Standard ISO 10360-3 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product specifications and verification. ISO 10360 consists of the following parts, under the general title Geometrical Product Specifications (GPS) Acceptance and reverifica

27、test of this part of ISO 10360 are applicable to CMMs which use a rotary table for the orientation of a workpiece being measured. The tests specified in this part of ISO 10360 are performed in addition to the size measuring tests according to ISO 10360-2, which are conducted with the rotary table st

28、ationary. They are designed to detect the system measuring errors relative to an axis system fixed to the rotary table. It is normally not useful to isolate the rotary table errors from other sources of machine error. ENISO103603:2001ENISO103603:2001 INTENRATIONAL TSANDADR ISO -063013:(0002E) ISO 00

30、ce of four-axis coordinate measuring machines (CMM) is in accordance with that stated by the manufacturer. It also specifies the reverification test, which enables the user to reverify the performance of a four-axis CMM periodically. The acceptance test and reverification test described in this part

31、 of ISO 10360 are applicable only to four-axis machines with three axes for measuring workpiece coordinates, plus a rotary table for orienting the workpiece. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of th

36、2 All irhgts seredevr 4 Requirements for metrological characteristics 4.1 Error of indication The errors of indication, FR, FT, FA, as defined in ISO 10360-1, for the three four-axis errors shall not exceed the maximum permissible errors, MPE FR ,MP E FT ,MPE FA , as defined in ISO 10360-1, as state

37、d by: the manufacturer, in case of acceptance tests; the user, in case of reverification tests. The errors of indication (FR, FT, FA) and the maximum permissible errors (MPE FR ,M P E FT ,M P E FA ) are expressed in micrometres. 4.2 Environmental conditions Limits to be respected for permissible env

38、ironmental conditions such as temperature conditions, air humidity and vibration at the site of installation that influence the measurements shall be specified by: the manufacturer, in case of acceptance tests; the user, in case of reverification tests. In both cases, the user is free to choose the

39、conditions within the specified limits. 4.3 Rotary table The maximum permissible errors (MPE FR ,MPE FT ,M P E FA ) apply for any permitted loading, location and orientation of the rotary table on the CMM and for any locations of the test spheres on the rotary table within specified limits. 4.4 Styl

40、us system Limits to be respected for the stylus system configuration, to which the stated values of MPE FR ,M P E FT ,M P E FA apply, shall be specified by: the manufacturer, in case of acceptance tests; the user, in case of reverification tests. In both cases, the user is free to choose the stylus

41、system configuration within the specified limits. The form deviation of the stylus tip will influence the measurement results and shall be considered when proving conformance or non-conformance with specifications. 4.5 Operating conditions The CMM shall be operated using the procedures given in the

42、manufacturers operating manual when conducting the tests given in clause 5. Specific areas in this manual to be adhered to are, for example: a) machine start up/warm up cycles; b) stylus system configuration; c) cleaning procedures for stylus tip and reference sphere; d) probing system qualification

43、; e) rotary table set-up and qualification. NOTE The stylus tip and the reference sphere should be cleaned before the probing system qualification so as to leave no residual film which could affect the measuring or test result.

44、ceptance test and reverification test 5.1 Principles The principle of the assessment method is to establish whether the CMM is capable of measuring within the stated maximum permissible errors (MPE FR ,M P E FT ,MP E FA ) by determining the variation of the measured coordinates of the centres of two

45、 test spheres mounted on the rotary table. It is noted that on a perfect four-axis CMM, the location of the measured centres of the test spheres would remain fixed in the workpiece coordinate system while the table is rotated. Each test sphere centre is determined in three directions: radial, tangen

46、tial and axial. The position of each test sphere centre is represented in the workpiece coordinate system on a rotary table. The centre of each test sphere, mounted on a rotary table, is measured in a series of measurements with different angular positions of the rotary table. The errors of indicati

47、on (FR, FT, FA) are calculated separately for each test sphere as the range between the maximum and minimum measurement results for each of the three directions. In the following: acceptance tests are executed according to the manufacturers specifications and procedures; reverification tests are exe

48、cuted according to the users specifications and the manufacturers procedures. 5.2 Measuring equipment 5.2.1 Two test spheres (A and B), with diameters no less than 10 mm and no greater than 30 mm and with certified form. The diameters of the two test spheres, used in these tests as the corresponding input quantities, need not be calibrated since only the centres of the test spheres are used to determine the three four-axis errors. The form of the test spheres must be calibrated since t
