To provide cutting technique which dissolves regular cutting traces on a workpiece generated in cutting, and can suppress generation of interference color due to the incident light on the workpiece or the one on which its shape is transferred.
In the cutting method, shape generation work is performed on the workpiece 1 by relatively moving and rotating the workpiece 1 and a cutting tool 4 around the axis while giving a predetermined depth of cut to the workpiece 1 by the cutting tool 4. The workpiece 1 and the cutting tool 4 are finely oscillated in the direction orthogonal to the relative cutting direction along the machined surface of the workpiece 1 in addition to the operation relatively moving and rotating the workpiece 1 and the cutting tool 4 around the axis.
