Dimensional Inspection
| Method | Accuracy | Application |
|---|---|---|
| CMM (Zeiss) | ±0.001 mm | All dimensions, GD&T |
| Optical Comparator | ±0.010 mm | 2D profiles, thread forms |
| Laser Scanner | ±0.020 mm | Organic shapes, reverse engineering |
| Bore Gauges | ±0.002 mm | Hole diameter verification |
Non-Destructive Testing
| Method | Detection Capability | Standard |
|---|---|---|
| Dye Penetrant | Surface cracks > 1 mm | ASTM E1417 |
| Ultrasonic | Subsurface > 0.5 mm | ASTM E2375 |
| X-Ray | Internal porosity > 1% | ASTM E1742 |
| Eddy Current | Surface cracks > 0.1 mm | ASTM E3097 |
Evidence Basis
Based on AS9100D quality-system requirements and ASME Y14.5 dimensioning/tolerancing, plus NDT standards ASTM E1417 / E2375 / E1742 / E3097. Method accuracies and detection limits are typical instrument capabilities.
Engineering Interpretation (titanium.blog)
(titanium.blog) Match the inspection method to the defect type and criticality: eddy current finds fine surface cracks (0.1 mm), ultrasonic finds subsurface flaws (0.5 mm), and dye penetrant finds surface cracks above 1 mm. CMM is the dimensional authority for GD&T; pair it with process control for titanium’s springback tendency.
