However, in the conventional groove processing apparatus as described above, the laser irradiator must be small in size because the laser irradiator is slidably supported, and the output of the laser is reduced. There were drawbacks. In addition, when the half body is made of wood, the mutually parallel sides of the knife-implanting groove become carbonized layers, so that when the knife is pressed into the groove, a fragile space is formed between the side of the knife and the wood of the die board. There is a problem that the fixing strength of the knife is reduced due to the intervening carbonized layer. Further, since the knife implantation groove is formed by continuous laser irradiation, the energy density of the laser is relatively small, and a groove having a large width cannot be formed by a single irradiation. For this reason, when the thickness of the knife to be implanted is large, once forming one side surface of the groove by continuous laser irradiation, the position is slightly shifted laterally and the other side surface of the groove is again irradiated by continuous laser irradiation. To form a groove for knife implantation with a large width dimension, and the processing efficiency was poor.

Further, when a knife implantation groove is formed by two small width grooves as described above, as shown in FIG. 10, a laser c is irradiated in a direction perpendicular to the axis b of the half body a. Therefore, when forming a groove in a direction substantially parallel to the axis b, the narrow groove d formed earlier and the narrow groove e formed later do not become parallel to each other in the cross section. As shown in FIG. 11, both side surfaces g, g of the knife implantation groove f having a large width dimension are inclined surfaces that gradually become wider outward with a mutual angle θ. For this reason, even if the knife is then press-fitted into the groove f, there is a problem that a gap is formed in a portion outside the groove f and the knife rattles.

First, as shown in FIGS. 1 and 2, a wooden cylindrical dieboard material 1 made of laminated plywood is mounted on a rotation holding frame 11 of a rotary support 4 and the material 1 is rotated about one axis L. While holding it as possible, the rotating support 4 is positioned directly below the irradiation nozzle 22.

Then, while controlling the feed in the direction along the axis L and the feed in the rotational direction (by an output signal from control means such as a computer, not shown), the direction orthogonal to the axis L is controlled. The laser irradiation nozzle 22 irradiates a pulsed laser. That is, laser irradiation is performed while controlling the rotation of the rotation holding frame 11 of the rotary support 4 of the die board material support board 2 and the feed of the intermediate support 7 in the left-right direction.

Then, as shown in FIG. 5, the knife implantation groove 28 is machined in a bead shape. Specifically, since the laser beam is intermittently irradiated as a pulse, the energy density of the laser increases, and a hole larger in the material 1 than the diameter of the laser is formed. By forming a plurality of the holes so as to be continuous with each other at a predetermined pitch, a bead-shaped knife implantation groove 28 having a large width corresponding to a thick knife can be formed. The groove 28 has wavy side surfaces having a plurality of vertices 29.

0, 30 occurs. Further, since both side surfaces of the knife implantation groove 28 are formed at the same time, as shown in FIG. 6, the both side surfaces are parallel to each other in a cross-sectional shape. Since the width of the knife implantation groove 28 can be adjusted by moving the laser irradiation nozzle 22 up and down to change the focal point, it is of course possible to form the groove 28 having a small width.

As shown in FIG. 8, when the knife K is press-fitted into the knife implantation groove 28 of the cylindrical die board B, as described above, both side surfaces of the groove 28 are parallel to each other in cross section. Therefore, there is no gap between the both sides of the knife K and the vertices 29 and 29 of the continuous wave of the groove 28 abutting on the knife K.

Then, a bead-shaped knife implantation groove similar to the groove 28 shown in FIG. 5 is machined. With this configuration, it is possible to provide a bead-shaped knife implantation groove 28 having a large width corresponding to a thick knife by performing only one laser pulse oscillation irradiation along a preset line (shape). A flat die board (not shown) is completed.
