<p>The present invention relates to a system for stacking metallic plates in three dimensions, which is capable of obtaining a desired 3D-shaped product by welding and incline-cutting metallic plates having various thicknesses by using a laser. According to the present invention, there is a system for manufacturing a 3D metallic plate by using metallic plates having mutually different thicknesses, which includes: a calculation control unit (11) for extracting a welding path obtained by offsetting a cutting section and an upper section having a thickness in the range of 0.05 mm to 10 mm and a form of a contour line having an inclined angle as much as a focus radius of a laser and angle data of the upper section and a lower section; a transfer plate (12a) for transferring a prepared plate and a remaining plate after the prepared plate is cut; a welding head set (13a) for laser-welding the transferred metallic plates having the same thickness along the path of the upper section offset as much as the focus radius of the laser; a cutting head set (13b) for performing an inclined cut along a sectional surface having an inclined angle; a numerical control device (13) including a laser oscillation device 13c; and a working support (12-1, 12-2) for transferring the prepared metallic plate in a z-direction.</p> |
