Abstract

From many decades reverse engineering (RE) has been used to make duplicate parts and part drawing prints in military and defence sectors. Scientific literature presents many different approaches for implementation of reverse engineering. Most of the studies are based on the analysis of point clouds acquired through coordinate measuring devices, such as, Coordinate Measuring Machines (CMMs), Optical Scanners or Interferometric Systems. In recent years, the development of computer technology resulted in the integration of design and manufacturing systems and automated inspection/gauging systems in manufacturing engineering applications. Geometrical information of a product is obtained directly from a physical shape by a digitizing device, from this complete 5-axis tool-path is obtained. Duplicating the part is done with the help of CMM and CAD/CAM software like   Mastercam, ProEngineer etc. CMM is used to digitize the mechanical object. Taking coordinates (scan data) of the various points on the surface of the object and converting it into IGES file and using the same in the CAD/CAM software with required interfacing creates a surface or solid model of the object. Finally this solid model is used to generate CNC part program to manufacture the part on CNC Machining center.
