Jiahangaero believes that the factors that affect the accuracy of CNC precision machining mainly include the heating of the machine tool, the error and wear of the tool itself, the machining position error, the machining system error, and the deformation error.

Common processing methods for aluminum alloys include: machining, stamping, precision casting, powder metallurgy, and injection molding.

Aluminum alloy has the advantages of low density, which can reduce the weight of the hull, is easy to process, has high plasticity, and does not have the advantage of magnetism. It is very popular in the shipbuilding industry.

the current lightweight development of the shipbuilding industry is inseparable from the application of aluminum alloy materials. The reason is that aluminum alloy materials have the advantages of small specific gravity, good corrosion resistance, good processing and forming performance, good welding performance, and small elastic modulus. Aluminum alloys for ships have excellent corrosion resistance, so aluminum alloy ships must be able to effectively resist the adverse effects of seawater on the use and service life of ships.
