Geometrical product specifications (GPS) - Acceptance and reverification tests for coordinate measuring machines (CMM) - Part 7: CMMs equipped with imaging probing systems (ISO 10360-7:2011)

This part of ISO 10360 specifies the acceptance tests for verifying the performance of a coordinate measuring machine (CMM) used for measuring linear dimensions as stated by the manufacturer. It also specifies the reverification tests that enable the user to periodically reverify the performance of the CMM. The acceptance and reverification tests given in this part of ISO 10360 are applicable only to Cartesian CMMs using imaging probing systems of any type operating in the discrete-point probing mode. This part of ISO 10360 does not explicitly apply to: ? non-Cartesian CMMs; however, parties may apply this part of ISO 10360 to non-Cartesian CMMs by mutual agreement; ? CMMs using other types of optical probing; however, parties may apply this approach to other optical CMMs by mutual agreement; ? CMMs using contact probing systems (see ISO 10360-2 for contact probing systems). This part of ISO 10360 specifies performance requirements that can be assigned by the manufacturer or the user of a CMM, the manner of execution of the acceptance and reverification tests to demonstrate the stated requirements, rules for proving conformance, and applications for which the acceptance and reverification tests can be used.

Geometrische Produktspezifikation (GPS) - Annahmeprüfung und Bestätigungsprüfung für Koordinatenmessgeräte (KMG) - Teil 7: KMG mit Bildverarbeitungssystemen (ISO 10360-7:2011)

Dieser Teil von ISO 10360 legt die Annahmeprüfungen zum Nachweis der Leistungsfähigkeit eines
Koordinatenmessgerätes (KMG) für Längenmessungen fest, wie sie vom Hersteller angegeben wird. Er legt
auch die Bestätigungsprüfungen fest, die es dem Anwender ermöglichen, wiederholt periodisch die Leistungsfähigkeit
des KMG zu prüfen.
Die Annahme- und Bestätigungsprüfungen in diesem Teil von ISO 10360 sind nur auf kartesische KMG mit
Bildverarbeitungssystemen aller Art anwendbar, die mit Einzelpunktantastung arbeiten.
Dieser Teil von ISO 10360 gilt nicht ausdrücklich für:
⎯ nicht-kartesische KMG, die Parteien dürfen jedoch durch gegenseitige Vereinbarung diesen Teil von
ISO 10360 auch auf nicht-kartesische KMG anwenden;
⎯ KMG mit anderen Arten der optischen Antastung, die Parteien dürfen jedoch durch gegenseitige
Vereinbarung diesen Ansatz auch auf andere optische KMG anwenden;
⎯ KMG mit berührender Antastung (siehe ISO 10360-2 für berührende Antastung).
Dieser Teil von ISO 10360 spezifiziert Leistungsanforderungen, die vom Hersteller oder vom Anwender eines
KMG festgelegt werden können, die Art und Weise der Durchführung der Annahme- und Bestätigungsprüfungen
zum Nachweis der festgelegten Anforderungen, Regeln für die Bestätigung der
Übereinstimmung und Anwendungen, für die die Annahme- und Bestätigungsprüfungen eingesetzt werden
können.

Spécification géométrique des produits (GPS) - Essais de réception et de vérification périodique des machines à mesurer tridimensionnelles (MMT) - Partie 7: MMT équipés de systèmes de mesurage imageurs (ISO 10360-7:2011)

L'ISO 10360-7:2011 spécifie les essais de réception pour vérifier que les performances des machines à mesurer tridimensionnelles (MMT) utilisées pour les mesures de dimensions linéaires sont telles que spécifiées par le fabricant. Elle spécifie aussi les essais de vérification périodique des performances des MMT.
Les essais de réception et de vérification périodique décrits dans l'ISO 10360-7:2011 s'appliquent uniquement aux MMT cartésiennes utilisant tout type de système de palpage imageur fonctionnant en mode de palpage discret.
L'ISO 10360-7:2011 ne s'applique pas explicitement: aux MMT non cartésiennes, bien que les clients et fournisseurs concernés peuvent mutuellement convenir de l'appliquer aux MMT non cartésiennes; aux MMT utilisant d'autres types de palpage optique, bien que les clients et fournisseurs concernés peuvent mutuellement convenir de l'appliquer à d'autres MMT à palpage optique; aux MMT avec systèmes de palpage à contact (voir l'ISO 10360‑2 pour les systèmes de palpage à contact).
L'ISO 10360-7:2011 spécifie les exigences de performance qui peuvent être fixées par le fabricant ou l'utilisateur d'une MMT, l'exécution des essais de réception et de vérification périodique pour démontrer les exigences spécifiées, les règles pour prouver la conformité et les applications pour lesquelles les essais de réception et de vérification périodique peuvent être utilisés.

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 interested 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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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 the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10360-7 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 reverification tests for coordinate measuring machines (CMM):
⎯ Part 1: Vocabulary
⎯ Part 2: CMMs used for measuring linear dimensions

Introduction
This part of ISO 10360 is a geometrical product specification (GPS) standard and is to be regarded as a
general GPS standard (see ISO/TR 14638). It influences chain link 5 of the chains of standards on size,
distance, radius, angle, form, orientation, location, run-out and datums. For more detailed information on the
relation of this part of ISO 10360 to other standards and the GPS matrix model, see Annex E.
The tests of this part of ISO 10360 have two technical objectives:
a) to test the error of indication of a calibrated test length using an imaging probing system;
b) to test the errors in the imaging probing system.
The benefits of these tests are that the measured result has a direct traceability to the unit length, the meter,
and that it gives information on how the CMM will perform on similar length measurements.
The structure of this part of ISO 10360 parallels that of ISO 10360-2, which is for CMMs equipped with contact
probing systems. The testing methodology between these two parts of ISO 10360 is intentionally similar. The
differences that exist may be eliminated in future revisions of either this part of ISO 10360 or ISO 10360-2.
All the definitions in Clause 3 will appear in the revision of ISO 10360-1:2000.

1 Scope
This part of ISO 10360 specifies the acceptance tests for verifying the performance of a coordinate measuring
machine (CMM) used for measuring linear dimensions as stated by the manufacturer. It also specifies the
reverification tests that enable the user to periodically reverify the performance of the CMM.
The acceptance and reverification tests given in this part of ISO 10360 are applicable only to Cartesian CMMs
using imaging probing systems of any type operating in the discrete-point probing mode.
This part of ISO 10360 does not explicitly apply to:
⎯ non-Cartesian CMMs; however, parties may apply this part of ISO 10360 to non-Cartesian CMMs by
mutual agreement;
⎯ CMMs using other types of optical probing; however, parties may apply this approach to other optical
CMMs by mutual agreement;
⎯ CMMs using contact probing systems (see ISO 10360-2 for contact probing systems).
This part of ISO 10360 specifies performance requirements that can be assigned by the manufacturer or the
user of a CMM, the manner of execution of the acceptance and reverification tests to demonstrate the stated
requirements, rules for proving conformance, and applications for which the acceptance and reverification
tests can be used.

measured between the axis of motion of the imaging probe CMM that is nominally perpendicular to the
measuring plane of the imaging probe and the plane of motion that is nominally parallel to the measuring
plane of the imaging probe
NOTE The expected usage is where the Z-axis is nominally perpendicular to the measuring plane of the imaging
probe and the XY plane is nominally parallel to the measuring plane of the imaging probe.

imaging probe bidirectional length measurement error
E
BV
error of indication of a calibrated bidirectional test length measured in any position within the field of view of
the imaging probe, nominally parallel to the measuring plane of the imaging probe, and using a single probing
point (or equivalent) at each end of the calibrated test length
NOTE 1 Testing E does not involve motion of the imaging probe CMM.
BV
NOTE 2 E is applicable only to imaging probe CMMs that are capable of making measurements in the field of view of
BV
the imaging probe, which may not always be the case.
3.19
imaging probe unidirectional length measurement error
E
UV
error of indication of a calibrated unidirectional test length measured in any position within the field of view of
the imaging probe, nominally parallel to the measuring plane of the imaging probe, and using a single probing
point (or equivalent) at each end of the calibrated test length
NOTE 1 Testing E does not involve motion of the imaging probe CMM.
UV
NOTE 2 E is applicable only to imaging probe CMMs that are capable of making measurements in the field of view of
UV
the imaging probe, which may not always be the case.

probing error
P
F2D
error of indication within which the range of radii can be determined by a least-squares fit of points measured
on a circular material standard of size, the measurements being taken on the test circle located anywhere in
the measuring volume by an imaging probe CMM in the discrete-point probing mode using motion of the CMM
between all successive points and with all points evenly distributed across the usable field of view of the
imaging probe
