The rigidity is low due to the plate shape, and when rotating while the shank 103 is held on the main shaft, the vibration of the main shaft and the vibration at the time of cutting causes the bottom blade 104 to oscillate, thereby reducing the cutting accuracy. There is. Further, the styrofoam material is formed by bonding foam particles, and the rotary cutting tool 101 for foam material has no rake angle a as the bottom blade 104 is directed toward the center of the tool, and the side blade 105 is made of styrofoam material. Rotating cutting tools
101 peels off the foaming particles itself on the processing surface, does not provide a smooth processing surface, and increases the cutting load.

The peripheral speed decreases as goes toward the center of the tool,
At the tool center position, the peripheral speed is 0, and the cutting tool 101 is being pressed against the processing surface of the Styrofoam material during feeding. Therefore, at the time of cutting, the foamed particles of the styrofoam material easily fall off, and the surface to be cut does not become a smooth machined surface, and the tool mark S remains on the machined surface of the styrofoam material as described above. Therefore, post-processing is required. In FIG. 6, S 1 is a pick feed, and S 2 is a capsphide.
