<p>PROBLEM TO BE SOLVED: To facilitate removal of butts, generated during cutting of a plate, from a product. SOLUTION: In this automatic programming device 10, shape data Ai for a laser beam-machined product produced by a CAD part 8 is read by a cam PART 11. The CAD part 11 picks up recessed or protrusion-shaped butt shape data Ab from a plurality of the butt shape data Ab contained in the product shape data Ai and division linear line data Bi to divide the interior of the recessed or protrusion-shaped butt shape data Ab is produced on the butt shape data Ab. An NC program to obtain butt data Av, hereafter called butt data Av, is obtained and fed to a laser beam machine 3. The recess or protrusion- shaped butt shape data Ab is easily removed from a product.</p> |
