Abstract
Computed tomography is a widely used method in the field of dimensional measurements. It is a non- contact, non-destructive measurement method that enables insight into both external and internal geometry of measured part which allows measurement of characteristics otherwise unreachable with tactile measurement methods. The biggest problem with computed tomography measurements is lack of metrological traceability. Because of the fact that a lot of parameters influence the whole measurement system, measurement uncertainty is still not evaluated. In this paper, influence of one of the influencing parameters, geometrical magnification, on results of dimensional and geometrical measurement characteristics was observed. Besides experimental research, simulations of computed tomography scanning were done. Measurement results obtained from both scanned and simulated models were compared and observed with regard to reference values. Results obtained from scanned model showed predictable behaviour compared to results obtained from simulated model.
