Validation is the subjective process that determines the accuracy with
which the mathematical model describes the actual physical phenomenon.
This research was conducted in order to validate the use of finite
element analysis for springback compensation in 3D scanning of sheet
metal objects. The measurement uncertainty analysis was used to compare
the digitized 3D model of deformed sheet metal product with the 3D model
obtained by simulated deformation. The influence factors onto 3D
scanning and numerical simulation processes are identified and analyzed.
It is shown that major contribution to measurement uncertainty comes
from scanning method and deviations of parts due to manufacturing
technology. The analysis results showed that numerical methods, such as
finite element method, can successfully be used in computer-aided
quality control and automated inspection of manufactured parts.
