Sinopsis

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.
