Abstract

When scarfing the end portion of a plate-like material with irregular deformations or undulations, such as distortions, undulations and warps, the undulations are successively corrected flat and the flattened end portion is scarfed by a rotary cutter to form a highly precise scarfed surface. When the end portion of the plate-like material 3 is scarfed by the rotary cutter 5, the pressing member 11 presses, while the cutting operation proceeds, at least a part of the surface of at least that portion of the plate-like material 3 which is to be cut away as a chip 17 at a position near the blades 5b of the rotary cutter 5 on a downstream side of the rotary cutter with respect to a rotary cutter movement direction, the surface of the plate-like material 3 pressed by the pressing member 11 being opposite the other surface held in contact with the cutter receiving table 7.
