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

摘要

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.
