Abstract

Reverse engineering (RE) is a very important branch of geometrically design and manufacture application area, and this technique are an important step in the product development cycle. The use of reverse engineering (RE) will reduce the manufacturing time and costs. Reverse engineering (RE) is the process of producing design details in the form of CAD model from the physical part in the process of the product design. After that, CAD models are used for manufacturing applications. The objective of this project is to make a comparison between both CAD/CAM programming namely DELCAM and CATIA V5 and to investigate the machining result for both software by focusing on surface roughness. Reverse engineering method is a best way to produce the form of CAD model from a physical part by using the 3D scanner. It is a rapid process to copy from physical part. To get a complete CAD model, the CAD model must be edited using Geomagic Studio software. Then, do the CAD/CAM programming by using Catia V5 and Delcam Software. Afterward, does the machining process using 3-Axis CNC Milling Machine and the result of the machining part will be analyzed based on surface roughness using surface roughness tester. Seven point location areas has been choose for surface roughness test, every each point take at least five reading. Refer to the result of surface roughness for both sample, the delcam sample is better compared to Catia V5 sample. For future work, while do the CAM/CAD programming the position of stock must be same for both software because it will affect the surface roughness of the sample during machining process. Uses are newest technology of 3D scanner, easy for user to used, multifunction and the scanning process time is short.
