NF ISO 10791-2, E60-172-2 (06/2023)

This document specifies, with reference to the ISO 230 series, geometric tests for vertical spindle (i.e. vertical Z axis) machining centers. This document also establishes tolerances for test results for general-purpose, normal accuracy machining centers. It is also applicable, in whole or in part, to other numerically controlled machines when their configuration, components and movements are compatible with the tests described in this document. This document applies to machining centers having three digitally controlled linear axes (X axis up to 5000 mm long, Y axis up to 2000 mm long and Z axis up to 2000 mm long ), but it also deals with additional movements such as those related to rotating, tilting and pivoting tables. Other tests, listed in Annexes A, B and C, cover the rotational axes of spindles, rotary tables and tilt cradles. Movements which are not mentioned are considered to be special characteristics, and the corresponding tests are not included in this document. This document takes into account in Articles 6 to 9 the four possible types of fixed and rotating tables described below: — Article 6: non-rotating horizontal tables; — Article 7: tables rotating only around a vertical axis C'; — Article 8: tables rotating around a vertical axis C' and tilting around a horizontal axis A'; — Article 9: tables rotating around a vertical axis C' and tilting around a horizontal axis B'. This document only deals with checking the geometric accuracy of the machine and does not deal with operational tests of the machine which are recommended to be carried out separately. Tests not relating to the pure geometric accuracy of the machine are covered in other parts of the ISO 10791 series.
