Comparison of product data model between Rapid Prototyping and CNC milling 3-axis

Abstract

Nowadays, there are high demands on products with high accuracy and quality, this is due to the development of new technology on machinery and computer software. This research has been done to compare the product data model by using CNC 3-axis and Rapid Prototyping to produce a model spanner. The format files that use consists of STL, IGES, VRML, VDAFS, STEP AP214, STEP AP203 and PRO E. The main purpose of this study was to find loss of data for each format file was design through Solidwork’s software. The format file has been simulating to generate tool path by using MasterCam software before machining process will be done. Using that simulation, be able to compare a quality of machining result from surface finishing aspect and machining time for each format file. As a result, only format file VDAFS a suitable for machining CNC 3-axis because that format file contain less of data loss when compared with other format file from surface roughness aspects and defect. While for RP, format files VRML a suitable for machining than STL, because file VRML does not committed to any data losses from aspects of color. Finally, these views provide a concrete guideline for choosing a suitable format file for machining CNC and RP to produce a product required.
