PROBLEM TO BE SOLVED: To provide a processing method using a cylindrical tool in which blade length can be used effectively with a simple control, and, by means of this, the life of a tool can be extended and accuracy degradation due to wear can be suppressed.SOLUTION: In a processing method using a cylindrical tool 11, first, a first part a of a workpiece 12 is processed in a direction shown by an arrow by using a first part A of the cylindrical tool 11, and, then, the second part b of the workpiece 12 is processed by using a second part B of the cylindrical tool 11. Furthermore, a third part c of the workpiece 12 is processed in a direction shown by an arrow by using a third part C of the cylindrical tool 11, and, then, a fourth part d of the workpiece 12 is processed by using a fourth part D of the cylindrical tool 11. Furthermore, a fifth part e of the workpiece 12 is processed in a direction shown by an arrow by using a fifth part E of the cylindrical tool 11. |
