DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a method for cutting a product (workpiece) having a plurality of objects according to the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 (a), 1 (b) and 1 (c), a plurality of objects 2a, 2b and 2c of the present invention (as will be described later, n is changed from one object depending on the viewing angle). In a method of cutting a product having an individual object appearing on the surface of the same product, an ornament (a pendant, a ring, or the like) is formed from a material such as gold, silver, platinum, brass, or acrylic by an NC processing device. , Key chains, etc.), figurines, clock faces, badges, souvenirs or gifts (birth, marriage, seven-five-three, various competition championships, etc.) Engraving multiple objects on the product.
Here, the one shown in FIG. 1A has a diameter of, for example, 22 m.
m pendant 1a (made of brass) and baby 2a
Is a sculpture on the surface. Also,
FIG. 1B shows a pendant in which a photograph of a girl 2b is engraved on the surface thereof, and FIG. 1C shows a pendant in which a photograph of a boy 2c is engraved. In addition, two projections 5b, 5b are formed at the upper end of each pendant, and serve for positioning at the time of V-groove cutting described later.

Then, these pendants 1a, 1b,
1c is a pendant 1 imitating a photograph of the puppy of FIG. 1 (b).
As shown in FIG. 2 which is an enlarged view of a portion A of FIG. 2B and FIG. 3 which is a sectional view taken along the line III-III in FIG.
(For example, 0.350 mm) so that the engraving point 3b shows a black image, and the engraving minimum depth Dmin (for example,
The sculpture point 4b having a thickness of 0.010 mm) is configured to indicate a white image, and the distribution of black and white as a whole allows, for example, the image of a girl shown in FIG. It will be formed by engraving on the surface.

Next, a method for cutting (engraving) a product or a processed product (for example, a pendant) having a plurality of objects according to the present invention will be described based on the manufacturing process shown in FIG.

First, as shown in FIG. 4, as a first step of the present invention, a photograph showing an image (for example, a baby) to be engraved (referred to as a moving object) is read by a scanner (resolution: for example, 400 dpi). .

Next, as a second step, the read image is stored in, for example, a commercially available software Photoshop (MA).
Image processing is performed using C). Here, in this image processing, the color is adjusted to set the range of the engraving depth of each part of the image (white is the engraving depth 0, black is the maximum (cutting) depth, for example, 0.350 mm) Becomes). Also, the resolution is set and the resolution is adjusted. Therefore, the image operation is performed at a resolution of 100 dpi, and the image size is, for example, 156.2 mm × 156.2 mm (for a 22 mm circular pendant), 142.0 mm × 142.0 mm (20 m
m × 20mm square pendant), 115.0mm × 1
66.8 mm (23.5 mm x 16.2 mm, for rectangular pendants) is adopted.

In this image processing, image gradation, so-called brightness and contrast, are changed from black to white (0 to 10).
0%) to adjust the distribution of white and black. In this image gradation, the input level is corrected as a correction level,
Performs black distribution and enhancement. In this case, black indicates the maximum cutting depth. Further, the output level is corrected to adjust the white level. In this case, 76% of the white color indicates the minimum engraving depth. By operating the white portion, a mirror surface in which a portion of 76% or more of white is not engraved (corresponding to a mirror portion outside the contour of the face)
Becomes If desired, a background such as a landscape can be engraved on the white portion.

As a third step, a process for transferring data obtained by image processing to processed data software is performed.

Here, data that has been subjected to image processing using software (for example, a commercially available market volume (MAC)) is converted into processed data. For that purpose, size designation (machining range), pitch, designation of cutter used for engraving (edge angle, edge width), designation of engraving depth (white part is 0 depth, black part is 0.4 mm depth) ), The engraving speed in the Z-axis direction and the feed speed of the cutter in the X and Y directions (plane direction).

For example, in one embodiment of the present invention, the cutter blade width is 0.15 mm, the blade angle is 28 °, the pitch is 0.35 mm, and the engraving depth is 0.07 to 0.07 in correspondence with the shading of the black portion. 0.35 mm. As a result, a large number of small holes having inverted trapezoidal cross sections with different engraving depths are engraved on the surface of the workpiece.

Next, in a fourth step, a metal plate (for example, 5 cm long and 10 cm long) having a predetermined thickness is attached to a cutting device, for example, an NC processing device, a die sinker, a die sinker, or the like.
Set a processed product (material) of a predetermined shape punched from a brass plate).

In the next fifth step, the processing data created in the previous third step is input, and engraving is performed on the processed product (material).

In the engraving step, an image is engraved on the surface of the processed product at a predetermined pitch and a predetermined engraving depth based on the input processing data corresponding to the predetermined processed product. Here, a white portion (engraving depth 0) and a black portion (shading of black is determined by the engraving depth) are formed by cutting according to the engraving depth. In particular, by combining the feed pitch of the image size with the processing size, the feed depth of the cutter in the Z-axis direction, and the width of the cutter blade in the previous image processing (second step), the cutting diameter of the cutter does not interfere with each other. It is also possible to freely select the production of an image with a fine pitch or the production with a coarse pitch and a deep engraving depth, or the size of an engraved image.

Here, for example, when the processed product is a gold material, the cutter rotation speed is set to 12,000 rpm. p. m, X, Y
Feed speed of the cutter in the direction of 0.5mm ~ 2.0mm /
Second, the feed speed of the cutter in the Z-axis (carving) direction is 0.5 m
m / sec or 1.0 mm / sec, and when the material is silver, 1.0 mm / sec or 2.0 mm / sec, respectively.
Seconds and, in the case of brass, 1.0 mm / sec or 2.0 mm / sec, respectively.

In this engraving step, a photograph A (shown by a white circle) and a photograph B (shown by a black circle) as shown in FIG.
A processed product having the two photographs is formed. FIG. 5 (b)
As shown in FIG. 3, a processed product having three photographs of a photogram A, a photoimage B, and a photoimage C (indicated by a double circle in the figure) is formed. Here, FIG.
The upper part of (a) and (b) is a schematic plan view of the engraving surface, and the lower part is a schematic sectional view thereof.

Further, in the next sixth step, outer shape (contour) processing data of the processed product, for example, a circular shape or a circular shape with a projection is manufactured. Here, for example, the output origin of the commercially available market volume (MAC), the commercially available
The data of the outer shape (profile) to be cut out is produced by matching the output origin of AM.

In the next seventh step, the outer shape processing data produced in the previous sixth step is input to the outer shape cutting device to perform the outer shape cutting of the processed product. In this case, as a tool for cutting out the outer shape, for example, a straight endless mill having a diameter of 1.0 mm is used and 5,000 rpm. p. m, and the end mill feed rate in the X and Y axes is set to 1.7 mm / sec, and the feed rate in the Z axis direction is set to 0.5 mm / sec or 1.0 mm / sec. hand,
Outer shape processing is performed. Then, at the time of the outer shape processing, the outer shape cutting is performed such that two projecting portions 5b, 5b are left at the upper end portion of the circular pendant as shown in FIG.

Then, after once removing the processed product from a processing device such as an NC processing device, the two projecting portions 5b, 5b
, And set in the processing device. In the final eighth step, as a finishing step after engraving,
In the case of a two-photograph body, after cutting (engraving) the two-photograph (n-photograph in the case of n-photograph) on the material (processed product), a white part (engraving depth) V-grooves are formed in the vertical and horizontal directions at a predetermined pitch while leaving the cutting surface of 0). At this time, as shown in FIG. 6, for example, cutting is performed so that the angle α of the surface on which the object A is engraved and the angle β of the surface on which the object B is engraved are different. As a result of this cutting, each object (1 to n object) can be seen from the same surface depending on the angle viewed by the reflection of light.

After the eighth step, the protruding portions 5b, 5b are removed by cutting. Further, hand engraving such as buffing may be performed on the engraved surface.

[0025]

According to the method of cutting a plurality of objects according to the present invention, a processed object having a plurality of complex objects from one to n can be processed by simple image processing of the object and engraving based on the image processing. Thus, it can be manufactured simply, quickly and inexpensively. Also, the manufacturing accuracy is extremely good.

Also, the object to be engraved can be easily selected from the photograph by a scanner as appropriate, and the same sculpture with high accuracy can be obtained without relying on the acquisition of a skilled technician and years of experience, intuition and skill. Can be manufactured in large quantities. Furthermore, by changing the angle of the cutter, the size of the cutting diameter, and the depth of the sculpture, the expression of the carved image can be changed according to the angle seen by the reflection of light. .
