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
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
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).
