THE USE OF REVERSE ENGINEERING TO CREATING A DIGITAL MODEL OF FACE GEAR FROM 3D POINT CLOUD

This paper describes the use of reverse engineering to creating a digital model of face gear from 3D point cloud. The construction of a computational model of a physical object was carried out using an optical three-dimensional scanner. Based on the cloud of points obtained in the process of scanning, a spatial digital model reflecting the geometry of an existing element was developed. Polygonization and mesh reconstruction allowed to create a discretized model that enabled the precise reproduction of the scanned object. The created model could be subsequently used to conduct appropriate analysis and simulation to verify the correctness and possible modification of the construction of scanned elements. Coordinate measurement technology to digitize surfaces in order to compare and evaluate real component parts with their theoretical data using a PC is needed in many different industrial sectors like design, construction, manufacturing, quality assurance etc.
