Reverse Engineering Using 3D Scanning and FEM Analysis

A reverse engineering process of a part including 3D scanning, CAD modeling and FEM analysis is presented in the paper. A cast bearing support has been selected as an example part for the investigation. The final goal of the investigation was to determine maximal allowable radial bearing load of the part. The parametric solid model necessary for the FEM was designed in CAD software using polygonal surface model of a part obtained by 3D scanning and subsequent data processing in 3D scanning software. A handheld scanner working on structured light principle was used for the scanning. The direction and intensity of the maximal allowable force was determined via FEM simulations in which different loading configurations were varied.
