Because a certain distance is always kept between the cutting torches, the two cutting torches firstly move transversely in the same direction to cut the bottom surface, and the situation that the bottom surface cannot be cut is ensured to be avoided when the bottom surface is cut. For a workpiece with a closed cross section, this action is also required to cut the top surface to ensure that the top surface is completely cut.
