Abstract:
A shearing method of a plate-shaped workpiece (6) for applying a shear force in a thickness direction of the plate-shaped workpiece (6) includes: a step for starting applying the shear force on the workpiece (6) with a clearance (C) between action points (21, 31) in a surface direction orthogonal to the thickness direction of the workpiece (6); a step for applying the shear force after the start of applying the shear force until a fractured surface is created in the workpiece (6); and a step for increasing the clearance (C) depending on a deformation of the workpiece (6) in the thickness direction after starting applying the shear force until the fractured surface is created in the workpiece (6).
