Computer-tomography CT, which is based on x-rays, was originally developed for medical applications. However, for several years, systems using the CT principle have been used in industry for non-destructive material inspection.
Completely new possibilities have now been created. by integration of computer tomography in a measuring machine.
The working piece is placed on a revolving stage and x-rayed. A detector converts the x-ray image into a digital 2D image for further processing. The object is then rotating through 360° and x-ray images are taken at several orientations.
Subsequently, a 3D reconstruction of the measuring points takes place, depicting the entire workpiece geometry!
The detected point cloud will be reconstructed by high performanced calculators in a 3D volume model. diversivied dencities, different materials or material inclusions will be clearly represented in varying grey colour graduations.
With these values you are able to analyse the whole part. It is not necessary to cut or to destroy the part.
Additional to the CT-software, we use the following software tools:
For the tomografic analysis all established CAD formats are possible. We prefer: STEP, IGES, DXF und Catia CAD formates..
The maximum permissible error according to ISO 10360 and VDI/VDE 2617 is:
E1: (2,5+L/120) µm, E2: (2,9+L/100) µm, E3: (4,5+L/75) µm
The maximum part dimensions is up to Ø350mmX350mm.
The penetration depth of the x-rax beam depend on the material and the geometry of the part.
The penetration depth in steel is approximatly 15mm with a 225KV installation.
On the other hand, Aluminium is up to 200mm practicable. Unproblematic are plastic and rubber parts.
