Machine tools — Test conditions for bridge-type milling machines — Part 1: Testing of the accuracy of fixed bridge (portal-type) machines

This document specifies, with reference to ISO 230-1 and ISO 230-2, geometric tests and tests for checking the accuracy and repeatability of positioning of numerically controlled axes for general purpose, normal accuracy, bridge-type milling machines with a fixed bridge (portal type). This document also specifies the applicable tolerances corresponding to the above-mentioned tests.This document is applicable to machines with moving tables and fixed double columns. It does not include single-column (open sided) machines and those with fixed tables and moving columns.This document deals only with the verification of the accuracy of the machine. It does not apply to the testing of the machine operation (vibration, abnormal noise, stick-slip motion of components, etc.) nor to machine characteristics (such as speeds, feeds, etc.), which are generally checked before testing the accuracy.This document provides the terminology used for the principal components of the machine and the designation of the axes with reference to ISO 841.

La présente partie de l'ISO 8636 ne traite que du contrôle de la précision de la machine. Elle ne concerne ni l'examen de son fonctionnement (vibrations, bruits anormaux, points durs dans ses déplacements d'organes, etc.) ni celui de ses caractéristiques (vitesses, avances, etc.), de tels examens étant, en général effectués avant le contrôle de la précision.La présente partie de l'ISO 8636 donne également la terminologie utilisée pour les éléments principaux de la machine et indique la désignation des axes conformément à l'ISO 841.NOTE En complément des termes utilisés dans les trois langues officielles de l'ISO (anglais, français et russe), la présente partie de l'ISO 8636 donne, dans l'annexe A, les termes équivalents dans les langues allemande et italienne; ces termes sont publiés sous la responsabilité des comités membres de l'Allemagne (DIN) et de l'Italie (UNI). Toutefois, seuls les termes donnés dans les langues officielles peuvent être considérés comme étant des termes de l'ISO.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
