たらすものである。(Effects of the Invention) Effect 1 The curved blade cutter according to the present invention facilitates the scoring of circular arcs required on the surface of the work plate material as described above, and smooth and safe rotary cutting and cutting work along a curved line. With respect to the blade width of the planting blade member, of course, on both sides of the countersunk member, of course, there are clearances on both sides (in the case of a sawtooth member, a set blade is used). (Width and clearance between both side surfaces), as described above, the side surfaces of the plate flange member and the planting blade member are on the surface of the work material, and in the situation where the rotary cutting and cutting work is continuously maintained in a continuous upright state, the plate flange The work is performed by maintaining the clearances on both side surfaces of the member, which brings about an important effect of satisfying the above-mentioned essential requirement (a) for cutting and cutting.

のである。Effect 2 Next, with respect to the above essential requirement (b), the countersunk member and the planting blade member or the sawtooth member of the curved blade cutter are formed into the conical shape, and further several lines are formed on the entire peripheral surface of the cone. By arranging the radial notch grooves at equal intervals, the inner angle of the cone is adjusted, and the circular curve for the circular marking of the work material and the conical curved arc of the plant blade member or sawtooth member are reasonably matched. Therefore, the effect of clearing the problem of the essential requirement (b) is satisfied.

ある。That is, as a reference example, the outer diameter of the tip of the curved blade cutter is 110.
When the diameter of the circle to be cut at φ is 250 m, the angle inside the cone of the curved blade cutter is 130 °, and the diameter of the circle to be cut is 480
In the case of porridge, the inside angle of the cone is 155 °, and similarly when the diameter of the circle to be cut is 960, the inside angle of the cone is 167 ° 30 '.
By selecting the in-cone angle of the curved blade cutter according to the size of the diameter of the circle to be cut, the effect of obtaining a rational cutting arc curved blade suitable for the circular arc of the scoring line requiring cutting is also great. .
