Adhesive matter remaining at the end of a cuboid metal material is reliably removed in a relatively short time while suppressing the decrease in yield rate of the metal material. Distances of the upper surface and the lower surface of a cuboid metal material from a reference position are measured using a distance measurement device in the longitudinal direction of the slab including the longitudinal end of the slab. On the basis of the measurement results, the state of remaining of adhesive matter remaining on the upper and lower surfaces of the longitudinal end of the slab is comprehended. On the basis of the state of remaining of adhesive matter, the amount and position of cutting by a cutting tool is determined. Corner removing cutting is performed on the upper and lower surfaces of the longitudinal end of the slab using the cutting tool in accordance with the determined amount and position of cutting.
