ができる。Then, when the flat surface of the work (9) is cut by the chip (7) of the cutting tool (b) while directly moving the work (9) on the table, the chip (7) has a front surface facing the work cutting direction. (12) is tilted backward, and the edge portion (12b) of the front surface (12) on the workpiece non-cutting side is the edge portion (12a) on the workpiece cutting side.
Since it is projected further to the front, the chips generated from the surface to be cut (14) of the work (9) form a spiral shape, and as shown by the arrow in FIG. Escape to the side, which is almost orthogonal to the cutting direction. Therefore, the chips do not go forward from the cutting point a, and it is possible to reliably prevent the chips from being caught between the chip (7) and the work (9).
