Reverse Engineering in Manufacturing

Abstract

Reverse Engineering in terms of mechanical engineering is interested in design,its processing includes a 3D scanning of theprimitive object, then it transfers itinto computer aid design(CAD) model (solid, surfaces…etc.), which involve the measurements and data sensing with high quality of 3D analysis. These models exploit in analyzing, manufacturing, modification and optimization, this branch is being applied into a wide field in factory products,such as automotive industries. By using reverse engineering, weobtain an accurate benefit as improving product quality, creating a complete overview of competing products, as well asreducing the time and the cost.

Most of the engineering majors focus on traditional engineering, which is based in the development and improvement of their products using geometric and abstract concepts by applying the scientific and mathematical principles to practical ends, such as the design manufacture, operation of efficient and economical structures, machines, processes, and systems. On the other hand, reverse engineering aims to create a CAD model by making 3D scanning of the object, and its partial component to analyze the internal relations of these partial components.

In order to observe a high accuracy models, the mechanical five dimensional (5D) machined parts are used for this situation. That helps to know and analyze all details and constrains of object. By understanding common design practices and manufacturing knowledge of 5D machining, it can be used to guide the reverse engineering process in order to achieve the best accuracy models.

Getting a CAD model requires professional packages, which deal with 3D scan data and create parametric CAD solids with high accuracy, and to minimize the time required.

Geomagic studio is a useful software used in reverse engineering, it provides amount of features, that associate redesign, Analyze, Seamless Data Transfer and other features together.
