COMBINATION OF SUBTRACTIVE & ADDITIVE MANUFACTURING TECHNIQUES IN A MULTI-PURPOSE CNC MACHINE

Abstract

Anything designed on paper or in CAD software, remains there unless fabricated up to the mark. Rapid Prototyping includes various manufacturing techniques that let us transform digital designs into physical objects, which can either be used to improve the product through design iterations or can be displayed as a product right after production. Any manufacturing technique can be classified as either subtractive, additive or formative. Rapid prototyping applies these production technologies to produce scale models or complete products using CAD data, with little or no human intervention. This project focuses at the combination of additive and subtractive manufacturing techniques like 3D printing, CNC milling and laser engraving. Such a machine can be helpful for the industry as well as the education department as it enables the users to make use of, both most commonly used rapid manufacturing techniques in a hybrid CNC environmen
