The cutting member 133 is connected at one end to the first elastic member 133a and at the other end to the second elastic member 133b so that the first movement bar 131 and the second movement bar 132 The length is compensated so as to be tightly connected.

As described above, the position adjusting unit 140 adjusts the vertical movement of the pair of vertical moving members 113a, the horizontal movement of the second moving member 123, and / or the vertical movement of the first and second moving bars 131 and 132 To the front-rear direction. The position adjustment unit 140 may be installed on the main body 110 or separately from the main body 110.

6 to 9, a process for cutting a work piece 10 into a three-dimensional shape of an amorphous work piece is performed by using an atypical work piece cutting apparatus 100 according to an embodiment of the present invention. The cutting method will be described below.

The present invention relates to a method of cutting a workpiece to produce an amorphous formwork. Here, the atypical form refers to a form suitable for pouring concrete of a concrete structure having a large surface curvature and a large change in surface protrusion and depression, unlike a form having a conventional standardized standard. Generally, formwork is a building material composed of wooden boards for supporting loads, plastic or foamed styrofoam for reproducing curvature, and the like.

As shown in FIG. 6, in step (A), data including curved surface information of a three-dimensional shape of an amorphous structure using an irregular shape is calculated to produce an irregular shape. As the data, the shape information for the three-dimensional shape, the volume information of the three-dimensional shape, the radius of curvature according to the curved surface of the three-dimensional shape, and the like may be included. In addition to the information described in this specification, to be.

In the step (B), the entire volume information of the atypical form of the data is primarily obtained, and the processing material 10 having a size corresponding thereto is prepared. The working material 10 may be foamed styrofoam having a material that can be easily cut by a cutting member 133 such as a hot wire, but is not limited thereto, and may be easily cut by a cutting member Needless to say, various materials can be used as long as they are made of a material.

Since, (B) in step, x-axis direction of the x radius of curvature (ρ _x), y in the axial direction y the radius of curvature (ρ _y), z the radius of curvature of the z-axis direction of the surface information of the atypical mold (ρ _z ) Is calculated. Then, in the data, the y curvature radius? _Y is divided into a predetermined first specification range (a <? _Y <b, where a and b are preset parameters) based on the _x radius of curvature? _X And the z-curvature radius? _Z is divided into a predetermined second standard range (a <? _Z <b). This is because the cutting member 133 cuts the surface of the processing member 10 while moving the cutting member 133 back and forth and / or up and down by the position adjustment of the position adjusting unit 140 with respect to the x axis.

In the step (B), the first standard range (a <rho _y <b) and the second standard range (a <rho _z <b) are divided into a plurality of groups according to the variables a and b. The first specification range (a <rho _y <b) is set to a narrow range when the _y- radius of curvature is small, and is set to a wide range if the radius of curvature of _y is large. The second specification range (a <rho _z < b) is predetermined to be a narrow range when the _z radius of curvature (rho _z ) is small and to a wide range if the _z radius of curvature (rho _z ) is large.

For example, the first standard range (a <ρ _y <b), when the y radius of curvature calculated by the data (ρ _y) is to have a random value in the range of not more than _{30cm, 0cm <ρ y <2cm} , 2cm < a _{ρ y <10cm, 10cm <ρ} y <30cm , such as a variable, a and b, a narrow range by varying the number, the first standard range (a <ρ _y <b) y, the radius of curvature (ρ _y) is less in the And, if the y-radius of curvature? _Y is large, it can be varied in a wide range.

In the same manner, the second specification range (a <rho _z < b) can also be divided into several ranges according to the _z radius of curvature rho _z . For example, the second standard range (a <ρ _z <b), when the z radius of curvature (ρ _z) calculated by data having an irregular figure in the range of not more than _{50cm, 0cm <ρ z <2cm} , 2cm <ρ z _{<10cm, 10cm <ρ z <} 30cm, 30cm <ρ z <50cm such as by varying the values of variables a and b, a second standard range (a <ρ _z <b) the z radius of curvature (ρ _z) is Can be varied to a narrow range if it is small and to a wide range if the _z- radius of curvature ( _z ) is large.

In the (C) step, a first standard range (a <ρ _y <b) is first replaced with a variable spacing (D1), a second standard range (a <ρ _z <b) the second variable interval (D2) So that a unit grid consisting of the first variable interval D1 and the second variable interval D2 is calculated.

The first variable interval D1 is variable as the first specification range (a <rho _y <b) according to the variables a and b is varied. The second variable interval D2 varies as the second specification range (a < _z <b) according to the variables a and b is varied.

In the step (C), the first variable interval D1 is changed in a narrow interval if the first standard range is narrow, the interval is changed in a wide interval if the first standard range is wide, and the second variable interval D2 is changed in the second interval When the standard range is narrow, the size is varied at wide intervals if the second standard range is wide. The unit grid is divided into units (units) according to the sizes of the first variable interval D1 and the second variable interval D2. The area is variable.

For example, the first variable gap (D1) y is the radius of curvature (ρ _y) is to have 0.5cm when in the range of 0 <ρ _y <2cm, y the radius of curvature (ρ _y) is 2cm <ρ _y <10cm , And when the radius of curvature _y is in the range of 10 cm < _{y y} < 30 cm, it can be standardized to 2 cm or the like.

In the second variable interval (D2) also z radius of curvature (ρ _z) is 0 <ρ _z <cases in the range of from 0.5cm to 2cm, the, z the radius of curvature (ρ _z) is 2cm <ρ _z <range of 10cm And 2 cm when the z-radius of curvature (rho _z ) falls within the range of 10 cm < p _z < 30 cm.

However, in the present embodiment, the range of the _y- radius of curvature? _Y or the range of the z-curvature radius? _Z , the numerical values of the first variable interval D1 and the second variable interval D2 are merely illustrative. And can be variously changed depending on the size of the irregular mold and the degree of curvature, and is not particularly limited by the numerical values described in this embodiment.

In the step (D), the yz coordinate of the workpiece is virtually divided into a plurality of unit grids. Here, the unit grid is varied in the y-radius of curvature (rho _y ) and the radius of curvature of the z-axis (rho _z ) on the basis of the _x- radius of curvature (rx) according to the information of the width- May be implemented in a plurality of units. The unit grid has a rectangular unit structure including a first variable interval (D1) and a second variable interval (D2).

As shown in FIG. 8, when the workpiece 10 is virtually divided into unit grids by the above process, in step (E), as shown in FIG. 7, the cutting member of the workpiece cutting apparatus for an atypical formwork The unit grids are continuously cut while the positions are adjusted by the position adjusting unit, and the workpiece is cut into a three-dimensional shape.

The cutting process of the processing member 10 shown in FIG. 7 will be described as follows.

As shown in Fig. 7 (a), the workpiece 10 is prepared. Here, the workpiece 10 may be provided in a hexahedron structure having a volume larger than the total volume of the atypical die according to the data calculated in the step (A).

Thereafter, as shown in Fig. 7 (b), the workpiece 10 is virtually divided into a plurality of unit grids. The unit grid shown in Fig. 7 (b) is obtained by virtually dividing a plurality of unit grids into the same area, instead of applying a unit grid divided into various standards shown in Fig. Fig. 7 (b) is merely an example of a virtual partition diagram in addition to Fig. For convenience of description, the present embodiment will be referred to as a "first unit grid (G1) to a fifteenth unit grid (G15)" for a plurality of unit grids shown in FIG. 7 (b).

The position of the second shifting member 123 is adjusted by the operation of the position adjusting unit 140 so that the cutting member 133 of the work piece cutting apparatus 100 for an amorphous form workpiece (10).

The first movement bar 131 and the second movement bar 132 are moved back and forth so that the inclination of the cutting member 133 is adjusted according to the _y radius of curvature? _Y by the operation of the position adjustment unit 140 and a pair of vertically movable members 113a are positioned above the workpiece 10 in accordance with the _z- radius of curvature? _z .

7 (d), the cutting member 133 is moved downward by the pair of vertically movable members 113a, and the first moving bar 131 and the second moving bar 132 are moved downward, And the first unit grid G1 is cut.

7 (d) to 7 (f), the cutting member 133 is moved from the second unitary grid G2 to the fifth unitary grid G5 to the lower portion of the workpiece 10 The surface of the processing member 10 can be continuously cut while passing sequentially.

When one side of the workpiece 10 is cut at an irregular shape by the cutting member 133 in the above manner, the position adjusting unit 140 moves the second moving member 123 to the other side of the workpiece 10, The pair of vertically movable members 113a are moved upward so that the cutting member 133 is operated to be positioned in the sixth unit grid G6.

Thereafter, as described above, the pair of vertically movable members 113a are moved downward in accordance with the z-curvature radius? _Z by the operation of the position adjustment unit 140, and are moved in accordance with the _y- radius of curvature? _Y The cutting member 133 sequentially cuts the sixth unit G6 to the tenth unit grid G10 while being moved back and forth by the first moving bar 131 and the second moving bar 132 . The above-described process is repeatedly performed so that the workpiece 10 can be cut at an irregular shape by the cutting member 133, as shown in Fig. 7 (g).

When the above-described method is applied to the cutting process of the unit grid G having various specifications, the shape as shown in FIG. 9 can be processed. Fig. 9 shows a part of the shape of an irregular mold in which the unit grid G is irregularly cut by the irregular-shaped workpiece cutting apparatus 100 in various sizes as shown in Fig.
