Meaning
Section five of the international standard for coordinate measuring machines specifies the test procedures for systems with multiple probing configurations. The document known as ISO 10360-5 specifies the methods for verifying the performance of systems using articulating probing heads or fixed multiple sensors. It focuses on the errors introduced when the machine switches between different probe orientations or sensors during a single measurement task.
Probing Error
Accuracy depends on the ability of the system to mathematically link various probe positions to a single coordinate frame. The standard requires the measurement of a calibrated sphere from multiple angles to calculate the location error. This ensures that a feature measured from the side matches one measured from the top.
Testing Equipment
Specific artifacts like reference spheres or precision plates are used during the verification process. The results must fall within the maximum permissible error stated by the manufacturer. Adherence to ISO 10360-5 provides a common language for comparing the precision of different metrology systems.
Industrial Compliance
Quality management systems often mandate the use of these standardized tests for equipment certification. Following the prescribed steps ensures that the CMM is capable of complex inspections. Regular audits confirm that the machine maintains its rating over time.
