ISO 10360-7:2011 PDF

Overview

ISO 10360-7:2011 - Geometrical product specifications (GPS) - Acceptance and reverification tests for coordinate measuring machines (CMM) - Part 7: CMMs equipped with imaging probing systems - defines standardized procedures to verify and reverify the performance of Cartesian CMMs that use imaging (vision/video) probing systems operating in discrete‑point probing mode. The standard specifies how to execute acceptance tests at installation and periodic reverification tests to demonstrate conformance with performance requirements stated by the manufacturer or user, and to ensure traceability of length measurements to the metre.

Key topics and technical requirements

• Scope and applicability
  • Applies to Cartesian CMMs with imaging probing systems in discrete‑point mode.
  • Not explicitly for non‑Cartesian CMMs, other optical sensing types or contact probes (see ISO 10360‑2 for contact probing).
• Performance parameters and tests
  • Length measurement errors: bidirectional (EB) and unidirectional (EU), including Z (perpendicular to imaging plane) and XY components.
  • Repeatability ranges (RB, RU): statistical range of repeated length measurements.
  • Probing performance (P2D) and probing error of imaging probe (FV2D): evaluation of the imaging probe’s ability to locate points.
  • Squareness error (ESQ): assessment of orthogonality between axes where relevant.
• Execution and conformance
  • Detailed measuring procedures, required artefacts/equipment, environmental and operating condition requirements, and rules for data rejection and proving conformance.
  • Includes annexes covering interim checks, calibrated artefacts, mathematical adjustments, and relation to the GPS matrix model.
• Traceability and uncertainty
  • Tests produce results traceable to the unit of length; guidance references ISO/TS 23165 for CMM test uncertainty evaluation.

Applications and practical value

• Use ISO 10360-7:2011 for:
  • Acceptance testing of new CMMs with imaging probes at delivery/installation.
  • Periodic reverification and maintenance checks to ensure ongoing measurement reliability.
  • Procurement specifications and contractual acceptance criteria between buyers and manufacturers.
  • Calibration and quality assurance in metrology labs and manufacturing inspection departments.
• Practical benefits include consistent, comparable performance verification, direct traceability to the metre, and documented evidence for quality systems (e.g., ISO 9001).

Who should use this standard

• CMM manufacturers and system integrators
• Metrology laboratories and calibration service providers
• Quality engineers, inspection managers, and CMM operators using imaging/vision probing
• Procurement and validation teams specifying acceptance criteria
