3D scan data captured by 3d scanner/ CMM can be compared with the corresponding reference data (CAD) for quality inspection. This is possible either for the complete surface area and/or for feature-based inspections with regard to tolerances.
Quality inspection with 3d scanner/CMM becomes very handy when:
- Need to measure soft parts: 3D scanning only touches the part with light, so there’s no part deflection or deformation.
- Measuring parts takes too much time: 3D scanning is exponentially faster at collecting measurements than contact-based techniques.
- Need to remeasure parts you don’t have 3D scanning creates a complete digital record that you can remeasure at any time.
- Not sure why some parts fail: 3D scanning measures the entire surface of a part, so you’re less likely to miss an unexpected deviation from nominal.
- You think you might be scrapping perfectly good parts: 3D scanning gives you a more complete view of your parts so you can make more informed decisions.
- Need to measure complex parts: 3D scanning measures every surface at millions of points, making it easy to inspect even the most complex shapes.
- Measure features with GD&T
- Use Best parts for comparison and analysis
- Display deviation color maps on 3D CAD models
- Work with large data sets easily.
- Increase measurement precision and trusted repeatability.
