ISO 10360-5:2020

Overview

ISO 10360-5:2020 defines acceptance and periodic reverification tests for coordinate measuring machines (CMMs) that use contacting probing systems with spherical or hemispherical stylus tips. The standard targets practical performance of the combined CMM and probing system - including single- and multi-stylus configurations - when measuring using discrete point and/or scanning modes. Tests are expressed in terms of maximum permissible errors (MPEs) because probing performance cannot be fully isolated from the CMM.

Keywords: ISO 10360-5:2020, CMM, contacting probing systems, multi-stylus, scanning mode, acceptance tests, reverification, MPEs.

Key Topics

• Scope and applicability
  • Applies to CMMs with any type of contacting probe and spherical/hemispherical stylus tips.
  • Includes single-stylus, fixed multi-stylus (e.g., star styli), separate multi-probe installations, articulating probes, stylus/probe changing systems, manual and automated CMMs, and scanning probes.
  • Not applicable to non-contacting probes (optical, laser) which require different procedures.
• Rated operating conditions
  • Environmental and operating conditions are specified for reliable testing and repeatability.
• Test equipment and setup
  • Requirements for test artefacts (e.g., test spheres), styli specification, and measuring equipment are covered.
• Test procedures
  • Single-stylus tests (discrete point)
  • Scanning mode tests (continuous contact)
  • Multi-stylus tests for fixed multi-probe, multi-stylus, and articulating probing systems
  • Optional ring-gauge test and small-sphere test procedures are referenced
• Data analysis and reporting
  • Procedures for computing location, size and form errors, opposing-styli evaluations, and conformance against MPEs.
  • Annexes provide interpretation guidance (Annex C), alternative limit specification methods (Annex D), and test variants (Annexes A, F).

Applications

Who uses ISO 10360-5:2020:

• Metrology and calibration laboratories performing acceptance or periodic reverification of CMMs.
• Manufacturing quality engineers validating CMM capability for production inspection tasks.
• CMM suppliers and integrators qualifying probe systems, stylus changes, or probe-changer installations.
• Inspection and R&D teams assessing measurement uncertainty impacts from multi-stylus configurations and scanning probes.

Practical benefits:

• Verifies real-world measurement performance of combined CMM + probing system.
• Reveals errors caused by probe extensions, multiple styli, articulations and scanning interactions.
• Helps specify and control MPEs for contract acceptance, QA programs, and calibration schedules.
