Reverse Engineering Based on Information Model

Abstract

This article is focused on application of the information model during the process of reverse engineering in order to advance it both as part of theoretical research and for practical purposes. Reverse engineering technology is presented in detail. Complete solid 3D model of a workpiece is created on the basis of mathematical model consisting 3D point cloud produced using the results of 3D scanning. Reverse engineering of the workpiece is carried out in Siemens Solid Edge CAD system. Quality of the final 3D model depends on the number and density of facets in an obtained mesh model of an object. Therefore, the mesh model is adjusted and optimized using tools of Siemens Solid Edge CAD system, and it is used as a fundament for making a virtual prototype of the workpiece. After the steps for creating a suggested information model are analysed and examined in detail, they are applied to the process of reverse engineering of an implant for thigh bone reinforcement. As a result, information model undergoes significant changes, particularly for the shape analysis and stress simulation stages. Along with creating a virtual prototype of the real object on the example of thigh bone, further designing of anatomically shaped implant is also considered. Thus, applying information model for creating an object provides advantages in reverse engineering process.
