    摘要： A method is provided for forming a spiral groove in the outer circumferential face of a columnar or cylindrical work (WK) by cutting, in which a side cutter (19) provided with a blade body on the outer circumference is rotated around an axis thereof, in a state of the axis of the side cutter (19) having been tilted at a predetermined angle relative to an axis of the work (WK), and furthermore in a state of the blade body of the side cutter (19) having been disposed so as to cut the outer circumferential face of the work (WK) by an amount of a depth of the groove, and the side cutter (19) is moved in a direction (M1) parallel to the axis of the work (WK), and in synchronization with this, the work (WK) is rotated around the axis thereof in an arrow direction (M2). The shape of the blade body that is used is, for example, a trapezoid whose short side is the tip part.
