Use of Computed Tomography in Dimensional Quality Control and NDT

Popis výsledku v původním jazyce

© 2020 Manufacturing Technology. All rights reserved The article deals with the application of computed tomography in dimensional quality control. The advantage of computed tomography is that the measured part is not influenced by measuring force. It is possible to measure complex parts and assemblies, their geometry, internal structure and defects in one step. The disadvantage of CT is decreasing accuracy and resolution when measuring high density materials or large parts, caused by the use of high accelerating voltage and current. The measurement result is influenced by many factors, not only the instrument itself and the set of measuring parameters, but it also largely depends on the sample material and even its geometry. Based on the requirements for dimensional inspection, an analysis of Zeiss METROTOM 1500 computed tomography X-Ray spot size was conducted. The dependence of the spot size of the X-Ray source on the accelerating voltage and current was determined for the given instrument, as well as the relation between the voxel size and the distance of the sample from the detector. Spot size and voxel size has to be in relation, since large spot size goes against small voxel size (resolution). Using calibration artefact, the influence of the acceleration voltage on the accuracy when measuring form and size of a sphere and the distance between centres of 2 spheres was evaluated.
