Aluminum ribbed plates can not only meet the strength requirements of the ship structure, but also reduce the weight of the hull itself, thereby improving the performance of the ship. Aluminum ribbed plates are a composite plate that is pressed into one piece by aluminum plates and aluminum reinforcement ribs. There is a difference between the hull structure size and the aluminum ribbed plate, so the aluminum ribbed plate needs to be cut.

[0003] In the prior art, aluminum ribbed plates are cut by CNC laser cutting or CNC plasma cutting, and are only cut on the side without ribs (flat plate surface). After the flat plate surface is cut and separated, the ribs are still connected together, and the ribs need to be cut one by one with an electric hand saw. Since the ribbed side is not flat, the electric hand saw is difficult to cut, the efficiency is low, and it is difficult to ensure high cutting accuracy. Summary of the invention
