Meaning
International standards that specify the testing procedures for coordinate measuring systems using computed tomography establish uniform criteria for dimensional evaluation. In industrial metrology, ISO 10360 11 defines how to measure and verify the spatial accuracy of these scan systems. The scope of this standard applies to both the initial acceptance testing by manufacturers and periodic reverification by users.
Calibration Framework
Standard reference objects such as spheres or ball bars of known dimensions are scanned at multiple positions within the measurement volume. The system compares the reconstructed dimensions from the scan against the calibrated values of the reference artifact. Discrepancies between these values determine the metrological capability of the scanning system.
Evaluation Procedure
Technicians perform multiple measurements across different orientations to capture direction-dependent errors and voxel distortion. The resulting error metrics must fall below the limits specified by the scanner manufacturer to pass the validation. Rushing the calibration run without stabilizing the system temperature leads to incorrect error reports.
Commercial Value
Suppliers who can demonstrate compliance with this standard can provide certified measurements that satisfy the stringent quality requirements of aerospace and automotive buyers. It avoids long disputes over dimensional tolerances because both parties rely on the same standardised testing framework. Investing in this rigorous verification before beginning high-volume production reduces the probability of batch rejection and ensures that parts from different manufacturing runs remain interchangeable.
