Description of 20/30386415 DC 2020

This document specifies the acceptance tests for verifying the performance of an optical CMS (Coordinate Measuring System) when measuring lengths as stated by the manufacturer. It also specifies the reverification tests that enable the user to periodically reverify the performance of the optical 3D CMS.

An optical 3D CMS that this standard intends to specify is a contactless area measuring sensor delivering 3D data in several individual single views by an optical measuring principle and transforming it into a common coordinate system. Typical optical measuring principles are pattern projection, fringe projection, and project-and-sweep a scanned line, or similar, delivering single views without assistance of external information related to position and orientation of the objects to be scanned relative to the CMS. Typical registration principles are based on a best fitting of commonly captured position information across at least two different single views, either or both by using reference targets or surface features of the objects to be scanned.

This standard applies to verification of the measuring performance of CMSs in case the surface characteristics (e.g. glossiness, colour) of the object to be scanned are restricted and within a cooperative range.

This standard does not explicitly apply to other types of CMSs, including those standardized by the other parts of ISO 10360 or other standards. In the list below, a metrological moving carrier is a mover equipped with scales measuring the position and/or orientation of the probing system, to be used as essential information for the determination of the measurement result.

• tactile CMMs (Cartesian metrological moving carrier): ISO 10360-2,

• imaging CMMs (Cartesian metrological moving carrier): ISO 10360-7,

• CMMs equipped with optical distance sensors (Cartesian metrological moving carrier): ISO 10360-8,

• laser trackers: ISO 10360-10,

• X-ray CTs: ISO 10360-11,

• articulated arm CMMs (anthropomorphic metrological moving carrier): ISO 10360-12,

• measuring instruments intended to measure surface characteristics: ISO 25178,

• optical microscopes,

• hand-held laser line(s) scanners.

Parties may apply this part of 10360 to the above or other type CMSs by mutual agreement.

This part of ISO 10360 specifies:

• performance requirements that can be assigned by the manufacturer or the user of the CMS,

• the manner of execution of the acceptance and reverification tests to demonstrate the stated requirements,

• rules for verifying conformance, and

• applications for which the acceptance and reverification tests can be used.
