Reverse Engineering- a General Review

The process of duplicating an existing part, subassembly, or product without the aid of drawings, documentation, or a computer model is known as reverse engineering. Reverse engineering is also defined as the process of obtaining a geometric CAD model from 3D points acquired by scanning/ digitizing the existing products. The aim of this paper is to review the reverse engineering process, and its role in the development, refinement and modifications in the existing design of product has been discussed. After a brief introduction, the various stages involved in reverse engineering, and its applications in different fields have been discussed. A brief historical events using reverse engineering technique have also been discussed at length.
