ABSTRACT:
A device and method for contouring three-dimensionally curved surfaces includes an elongated contouring assembly that is supported at opposite ends by height adjustment mechanisms. The height adjustment mechanisms raise and lower the ends of the contouring assembly independently of each other, thereby allowing the contouring assembly to create a three-dimensionally curved surface as it passes over an area to be contoured. The control of at least one end of the contouring assembly is based on a comparison of its measured position with a profile of the surface to be leveled that is stored in a computer memory. A pivot or tilting controller may control the tilting of the contouring assembly to follow the slope of the profile stored in computer memory.
