ABSTRACT:
A method is disclosed for producing signs having raised, prismatic graphic images such as letters, numbers and other graphic images. Initial values for the graphic images are provided, and includes information defining an initial graphic representation for the graphic images, and may also include a return, which is the measure of distance by which the graphic images are raised relative to a background of a sign. A cutting tool is provided and has a radius and a cutting angle. One tool path is determined using the initial graphic representation. Tool passes and depths for the other passes are determined using the initial graphic representation, the cutting angle, and a distance which is not greater than the tool radius. A controller generates signals indicative of the tool paths and respective depths, and presents the signals to operate an automatic cutting machine and cutting tool to selectively remove material from a sheet material to produce the graphic images.
