Using 3 axis CNC (computer numerical code) routing processes of the Visualization Lab, the CNC was tested for 3D object milling. The CNC process was designed for manufacturing 2D cut out objects with or without a 3D surface. The processes of modeling the object, using CAM (Computer Aided Manufacturing) programs, producing the Toolpath, post processing, editing G Code, positioning the stock material, and setting the machine origin were tested for an understanding of what changes had to be made to the process to accurately mill and cut out 3D objects. Solutions were discovered through digital and physical setups that are designed to reference one another accurately though CNC. The process of designing the digital object in the Rhinoceros 3D modeling program became the way in which the Toolpaths were designed to produce the physical object as well as the means of material attachment and indexing, thus allowing 3D object creation.
