Abstract
One of the methods to decrease the technology gap between different countries and to transfer complex technologies is reverse engineering. In Reverse engineering of mechanical parts it becomes necessary to obtain a geometric model of a part either to modify the existing design or to analyze it using schemes such as the Finite Element Method (FEM). The
objective of this work is to develop and construct the solid model of an existing machine part by the geometric analysis of three copies of this part. Shape and dimensions of the part are obtained using laser scanner arms and the probing mechanism of a Coordinate-Measuring Machine (CMM). Segmentation & surface fitting are conducted using Geomagic Studio 12 software and the solid models as well as the workshop drawings are generated on UGS NX 7.5 CAD software. Material analysis and mechanical testing are performed to identify the polymer from which the part is produced. The prototype of this part is constructed Using 3D rapid prototyping machine using the STL file of the produced CAD solid model. The final results of this work are the construction of the complete solid model of the part with all its features and dimensions as well as its material using reverse engineering techniques.
