| Summary: | Performance verification of a coordinate measuring system (CMS) is important for instrument acceptance, reverification, comparability as well as measurement traceability to the definition of the meter. State-of-the-art ISO 10360 standard series is the reference text about the procedure of verification for CMS. Specifically, ISO 10360-8 considers optical distance sensor based CMSs. This article proposes procedures and artifacts for performance verification of focus variation-based CMS for a simultaneous 4-axis measuring mode. The proposal is inspired by, but goes beyond, the ISO 10360 standard, proposing an original solution for simultaneous linear and rotational axes verification.
