This document specifies, with reference to the ISO 230 series, the geometric tests for machining centres with vertical spindle (i.e. vertical Z-axis).This document also establishes the tolerances for the test results corresponding to general purpose and normal accuracy machining centres.This document is also applicable, totally or partially, to other numerically controlled machines, when their configuration, components and movements are compatible with the tests described herein.This document applies to machining centres having three numerically controlled linear axes (X-axis up to 5 000 mm length, Y-axis up to 2 000 mm length, and Z-axis up to 2 000 mm length), but refers also to supplementary movements, such as those of rotary, tilting, and swivelling tables. Further tests, contained in Annexes A, B and C, cover axes of rotation of spindles, rotary tables and tilting cradles. Movements other than those mentioned are considered as special features and the relevant tests are not included in this document.This document takes into consideration in Clauses 6 through 9 four possible types of tables, fixed and rotary, as hereunder described:— Clause 6: horizontal non-rotating tables;— Clause 7: tables rotating only around a vertical C’-axis;— Clause 8: tables rotating around a vertical C’-axis and tilting around a horizontal A’-axis;— Clause 9: tables rotating around a vertical C’-axis and tilting around a horizontal B’-axis.This document deals only with the verification of geometric accuracy of the machine and does not apply to the testing of the machine operation, which are generally checked separately. Tests not concerning the pure geometric accuracy of the machine are dealt with in other parts of the ISO 10791 series.

La présente partie de l'ISO 10791 spécifie, par référence à l'ISO 230-1, les essais géométriques pour centres d'usinage (ou les machines de fraisage, d'alésage, etc., à commande numérique, le cas échéant) à broche verticale (c'est-à-dire à axe Z vertical). La présente partie de l'ISO 10791 s'applique aux centres d'usinage ayant comme base trois axes commandés numériquement, c'est-à-dire trois linéaires (X, Y et Z) jusqu'à 2 000 mm de long, mais elle traite également des mouvements supplémentaires, tels que les axes rotatifs (A', B' et C'), ceux liés aux broches coulissantes, aux coulants ou aux têtes universelles. Les mouvements autres que ceux mentionnés sont considérés comme relevant de caractéristiques particulières, et les essais correspondants ne sont pas inclus dans la présente partie de l'ISO 10791. La présente partie de l'ISO 10791 décrit les essais géométriques pour les broches horizontales en variante de même que pour les deux types possibles de têtes universelles dans les annexes suivantes: - annexe A: broches horizontales en variante (essais AG1 à AG6); - annexe B: têtes rotatives, à un axe de rotation contrôlé numériquement (essais BG1 et BG2); - annexe C: têtes pivotantes, à deux axes de rotation contrôlés numériquement et perpendiculaires l'un par rapport à l'autre (essais CG1 à CG7). La présente partie de l'ISO 10791 ne traite que du contrôle de la précision de la machine. Elle ne concerne pas l'examen de son fonctionnement, qu'il est recommandé d'effectuer séparément. Certains essais concernant les performances de la machine fonctionnant à vide ou dans des conditions de finition sont traités dans d'autres parties de l'ISO 10791.
