High-resolution CT-based defect analysis and dimensional measurement
With industrial X-ray computed tomography (CT), even low-contrast defects in cast parts, such as cracks, pores and blowholes, can be localised and measured in three dimensions. Analysis of the defects can be performed using either multi-positional two-dimensional (2D) cross-section planes or the three-dimensional (3D) volume view. Complete 3D mapping means that CT can also be used for the non-destructive 3D measurement of cast parts that cannot be inspected using conventional coordinate measuring machines on account of their complex internal geometry. Therefore, CT has numerous practical uses in addition to non-destructive quality control. For instance, it can be used for optimising and reducing the time required for development and initial sampling processes, comparing components with the target CAD model or reverse engineering in which 3D component data is used to construct a three-dimensional CAD model (Figure 1). Fully automated scanning and analysis processes mean that the creation of first article inspection reports, even for complex components, is possible in less than an hour.
