Abstract
A plurality of cutting blades is linearly arranged on the right and left sides of a plate that is placed vertically. The cutting blades on one side are arranged so as to face downward, and the cutting blades on the other side are arranged so as to face upward. With a tool thus formed, a cutting operation is performed by making a circular motion in a plane in which the cutting blades are formed, and the cutting operation using the circular motion is repeated with the tool shifted by a predetermined pitch in a cutting direction. The tool is tilted in the cutting plane when subjected to high stress.
