Using a Werth HV 500 computer tomography measuring machine, we can scan workpieces and create their 3D point cloud (STL) and image with short deadlines. If the part fits in a cylinder that is 500 mm in diameter and 700 mm in height, then it can be successfully measured with CT.

The workpiece should not necessarily be made of one material only. CT technology is applicable to measure workpieces made of different plastics, metals like aluminium, copper, steel up to a certain strength, porcelain, glass and carbon fibre.

CT measurement yields the so called 3D point cloud of the workpiece. This dimensional point cloud is applicable for controlling both internal and external dimensions.

The workpiece can be a multi-part complex element, too. CT measurement makes it possible to inspect assembled parts in a non-destructive way.

After CT scanning, non-destructive material inspection can take place.

The necessary measurements are carried out by specially trained and practised engineers based on the scanned 3D point clouds:

• the point cloud is fit onto the CAD model using the so called BestFit method, then the difference between the workpiece and the model is determined;
• measurements are carried out on the 2D X-ray image;
• at an arbitrary point of the workpiece, a cross-sectional image is created, on which the required geometric dimensions are measured; in this way not only the external but also the difficult to reach internal dimensions can be determined with high accuracy;
• non-destructive inspections like searching for cracks, bubbles or inclusions are carried out on the workpiece;
• in the case of more complex, multiple material workpieces the elements with different material properties can be inspected;
• for assembled, multi-part and multi-material workpieces connection points and surfaces can be checked with non-destructive inspection;

An official report is issued about the executed evaluations including the results of each measurement task.
