Abstract: A method of producing intricate, three-dimensional artwork requiring high resolution on the part of a Computer Numerical Control (CNC) machine is disclosed. An existing three dimensional carving is captured by a computer, and converted into a NURBS surface. The operator sets forth the dimensions of the surface to be carved, including the width and the length, as well as the width of its component stiles and rails. The operator further selects the corners of such surface in which the artwork is to be carved. Thereafter, the NURBS surface is scaled and positioned in accordance with the dimensions and parameters supplied, and transmitted to respective CNC machines. The CNC machines then perform a series of carving operations in accordance with the instructions supplied by a G-code file processed from the NURBS surfaces.

Abstract: A method for surface-based machining of a decorative article is provided. The method includes retrieving a first graphical representation of the decorative article, and deriving a surface representation therefrom. The surface representation may have one or more segments. The method also includes deriving a tool path for each of the segments of the surface representation. By machining a workpiece in accordance with the tool paths, the decorative article is produced.
