Abstract
A computer-produced carved sign having three-dimensional surfaces, is produced by a method which comprises designing on a computer-aided design system, a three-dimensional graphical model of the signage work having three-dimensional surfaces to be carved in a signboard. On the computer-aided design system, a desired mathematical representation of the three-dimensional graphical model of the signage work to be carved in the signboard, is determined, and the desired mathematical representation is provided to a computer-aided machining system having a carving tool. Material constituting the signboard is removed using the carving tool moving under the controlled guidance of the computer-aided machining system. The CAD system allows the user to input an alpha-numeric character. The CAD system automatically creates the machining path by developing similar outlines of the alpha-numeric character and projects these outlines into the 3D graphical model. In another embodiment of the invention, the CAD system displays a model of the machine tool removing material from the workpiece to allow the user to change the CAD program before actual machining.
