Study and Analysis of the Advancement of CNC-Rapid Prototyping Application in Modern Automated Manufacturing

Abstract

This study reviews the advancements of computerized numerical control technology in the rapid prototyping process, which can be divided into the categories: subtractive, additive, and virtual. CNC rapid prototyping falls under the subtractive group, where the material is removed from the workpiece larger than the final product. Subsequently, few developments have been made to optimize the operation and increase the capabilities of CNC rapid prototyping to be on par with typical additive rapid prototyping. These advancements include the integration of machining and deposition developments, the adoption of rapid prototyping into the conventional machine, and the optimization of the CNC rapid prototyping process based on controlled parameters. The study concludes that the computerized numerical control rapid prototyping research area has ample room for improvement, similar to conventional machining processes. Supplementary signs of progress and innovations will develop the usefulness of this technique and decrease the restrictions of the present methodology in fabricating prototypes.
