Surface Cracks

Evaluating the width and depth of surface cracks is important for a great many materials and parts. The depth of the crack is hardest to determine, and is usually the most critical parameter.

4D InSpec is able to look down into cracks with remarkable success. In the screenshot below, the crack (on the left) is measured and analyzed using the Find Features analysis screen. The software three areas that match the parameters, including a light blue area that is over 400µm deep, and adjacent areas that are offset from the surface (gray) by 170 µm (violet), and 102 µm (tan).

The feature analysis parameters are adjustable by the user by entering different minimum and maximums, so you design your own analysis, to your specific requirements.

Working with replicas and 4D InSpec

4D InSpec can measure many of the same features you use Replica material for, with the advantage that it does it instantly, and without consumable costs.

But if you have features that are too obscured for 4D InSpec to see directly, there is good news: the gauge measures replica material in 3D too. That means you don’t need to cut a replica and use a shadowgraph, you can accurately and repeatably measure an area of concern.
