Description of the Related Art Conventionally, when a large number of strip-shaped small steel plates are cut out from a standard length steel plate or a large-sized scrap material by using an automatic fusing machine, a fusing torch is predetermined on a torch support table which moves relative to a workpiece mounting table. By fixing it to the interval, by relatively moving the workpiece (steel plate) and the fusing torch held on the workpiece mounting table in one direction, a strip with a predetermined width is formed once,
This strip was cut into a predetermined length to form a small steel plate having a predetermined size. In addition, after moving the torch support table or the work piece mounting table in the + X direction, the torch support table is moved in the + Y direction, and again in the + X direction and then in the + Y direction. Accordingly, there is also proposed a method in which a cutting line is formed in a key shape and a strip-shaped small steel plate is cut out.
