Evaluation on a Digitized CAD Model of 3D Scanner Used in Reverse Engineering

Reverse engineering has been widely used in the design and manufacturing processes of mechanical parts. The CAD model of reverse-engineered parts can be modified and redesigned to create a scale model of an existing part. The objectives of this project were to re-evaluate a reverse-engineered CAD model and create a scale model by machining process obtained from a CAM design. Initially, the digitization of an object was performed using 3D scanning devices. Re-evaluation of the designed part was executed using Geomagic Design software. NX software was used for generating a CAM design. Finally, the machining process of the real scale part was conducted using CNC 3 Axis. This work has contributed to the practical education for the abilities of a 3D scanner used in reverse engineering.
