9、of national standards bodies (ISO member bodies). 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. I
10、nternational 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
11、 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

17、t license from IHS -,-,- ISO 10791-8:2001(E) iv ISO 2001 All rights reserved Introduction A machining centre is a numerically controlled machine tool capable of performing multiple machining operations, including milling, boring, drilling and tapping, as well as automatic tool changing from a magazi
18、ne or similar storage unit in accordance with a machining programme. Most machining centres have facilities for automatically changing the direction in which the workpieces are presented to the tool. The purpose of ISO 10791 is to supply information as wide and comprehensive as possible on tests and
19、 checks which can be carried out for comparison, acceptance, maintenance or any other purpose. ISO 10791 specifies, by reference to the relevant parts of ISO 230, Test code for machine tools, several families of tests for machining centres with horizontal or vertical spindle or with universal heads
20、of different types, standing alone or integrated in flexible manufacturing systems. ISO 10791 also establishes the tolerances or maximum acceptable values for the test results corresponding to general purpose and normal accuracy machining centres. ISO 10791 is also applicable, totally or partially,
21、to numerically controlled milling and boring machines, when their configuration, components and movements are compatible with the tests described herein.

23、10791 specifies a method of checking the contouring performance of machining centres (or numerically controlled milling machines, etc., where applicable) by conducting circular tests in the three coordinate planes (XY, YZ and XZ) and by evaluating the radial deviation, F, and circular deviation, G,
24、in accordance with ISO 230-4. NOTEMeasurements of circular movements can be carried out by different methods as described in 6.6 of ISO 230-1:1996. These methods consist of using a rotating one-dimensional probe and a test mandrel, a circular masterpiece and a two-dimensional probe, or a telescoping
