Numerical control cutting method, steel structure and ship

Abstract

The invention discloses a numerical control cutting method, a steel structure and a ship, and relates to the technical field of shipbuilding or steel structure manufacturing. The numerical control cutting method comprises the following steps that S1, a steel plate is fixed to a cutting machine; S2, a workpiece close to the edge of the steel plate is selected as a first workpiece, a starting pointis selected on the first workpiece, and a cutting head of the cutting machine is aligned with the starting point; S3, the cutting machine is started, and one edge of each workpiece is sequentially cutfrom the starting point until the edge, away from the first workpiece, of the last workpiece is cut; and S4, the cutting machine is operated to move reversely, cut the remaining edges of each workpiece sequentially from the last workpiece till the cutting machine returns to the starting point of the first workpiece. When the workpieces are cut through the method, only one cutting starting point exists, and therefore consumption of consumable products of a cutting nozzle of the cutting machine can be reduced; and meanwhile, continuous cutting is adopted among all the workpieces, bridging connection does not exist between the workpieces, and therefore the cutting efficiency of the workpieces is improved, and the workload of workers can be reduced.

Description

technical field [0001] The invention relates to the technical field of shipbuilding or steel structure manufacturing, in particular to a numerical control cutting method, a steel structure and a ship. Background technique [0002] CNC cutting of steel parts is generally achieved by cutting machines that automatically cut through cutting codes. At present, there are two main methods of CNC cutting. The first is to cut one part and then cut the next part. The second is to directly connect the parts through bridges to achieve the purpose of continuous cutting. The above-mentioned first cutting method will have a large number of cutting starting points and arc-extinguishing points, which will affect the cutting efficiency and the consumption of cutting consumables. The second method will increase the work of connecting bridges for secondary cutting on site, and will also affect the cutting of parts. Quality, while greatly increasing the workload of designers.
