초록

One of the most important things in shipbuilding is to select light and high tensile strength materials. Therefore, the use of Al alloy in shipbuilding become an increase. In cutting the aluminum plate, the quality of the cut surface is strongly influenced by the cutting conditions such as cutting speed, kerf width, plate thickness, cutting materials, and applied gas pressure. The cutting experiment of Al alloy plate(5083) were carried out using LASER cutting machine. The upper and lower of kerf width, the surface roughness(Ra, Rmax) of cut surface were measured under various cutting conditions. The morphologies of cutting surface were also monitored at various cutting conditions. The optimum cutting conditions of Al alloy among tested were indicated.
