Development drawing production system and development drawing production method using same

Abstract

In industrial fields such as glass, steel plate, and plywood manufacturing, work instructions containing necessary work information are received, and work for manufacturing products is performed on the basis of the work instructions. The work instructions may include a development drawing. A worker cuts and bends a material with reference to the development drawing of the work instructions to manufacture a product. The development drawing may be manually drafted by a designer who can draft the drawing. Due to the characteristics of manual work, the work speed is limited, and when the drawing is drafted hastily within a limited time, the accuracy may decrease, thereby resulting in inaccurate design work. The present invention provides a method and a system for producing a development drawing. The method comprises the steps of: obtaining a bending drawing; producing a 3D drawing on the basis of the bending drawing; and producing a development drawing on the basis of the 3D drawing.

Description

Deployment drawing generation system and deployment drawing generation method using the same

[0001] The present invention relates to a development drawing generation system and a development drawing generation method using the same.

[0002] In industrial sites such as glass, sheet metal, and plywood manufacturing, work instructions containing necessary work information are received and work to manufacture products is performed based on these instructions.

[0003] Work instructions may include a development drawing. Workers use the development drawing in the work instructions to cut and bend materials to manufacture the product.

[0004] Therefore, the accuracy of the development drawing can affect the quality of the product and the waste rate during the product production process.

[0005] Developed drawings can be created manually by designers capable of producing drawings. While these drawings can be prepared in advance with ample time, they may be created on-site in a short period of time due to design changes. In these cases, the pressure to create the drawings can lead to a decrease in accuracy.

[0006] In addition, due to the nature of manual work, even if drawings are created within a minimum amount of time, there are limits to the speed of the work, and if drawings are created hastily within a limited time, the accuracy may decrease, resulting in inaccurate design work.

[0007] This may result in a decline in the quality of products produced based on the development drawings, and may also lead to an increase in the waste rate in the production process.

[0028] Hereinafter, an embodiment of the present invention will be described with reference to the attached drawings.

[0029] FIG. 1 is a flowchart of a method for generating a development drawing of the present invention, FIG. 2 is a block diagram of a development drawing system (1000) of the present invention, FIGS. 3 to 5 are implementation examples of a development drawing generation system (1000) of the present invention, and FIG. 6 is an example of a work order (JO) output by a development drawing generation system (1000) of the present invention.

[0030] The method for generating a development drawing of the present invention can be performed in the development drawing generation system (1000) of the present invention. The development drawing generation system (1000) of the present invention is configured to include a control unit (100) and a display unit (DS) that displays a drawing received from the control unit (100).

[0031] The method for generating a development drawing of the present invention comprises a step of obtaining a bending drawing (BP), a step of generating a 3D drawing (TP) based on the bending drawing (BP), and a step of generating a development drawing (PG) based on the 3D drawing (TP).

[0032] Referring to FIGS. 1 and 3, the control unit (100) can obtain the bending drawing (BP) by selecting a bending drawing (BP) that has already been created externally or by manually creating a bending drawing and adding the bending drawing (BP) in the step of obtaining the bending drawing (BP).

[0033] In other words, in the method for generating a development drawing of the present invention, the control unit (100) obtains a bending drawing (BP) by inputting the bending drawing (BP) from the outside.

[0034] Referring to FIG. 3, the control unit (100) transmits the acquired bending drawing (BP) to the display unit (DS). The display unit (DS) can display the received bending drawing (BP) in the bending drawing display area (FD1).

[0035] Specifically, the display unit (DS) includes a selection input window display area (FD4) including a bend drawing (BP) selection window and a bend drawing (BP) addition window in the first display window (DW1), a bend drawing display area (FD1), an elevation drawing name and quantity display area (FD2) of a product (Ganemo Door in the drawing) including a material corresponding to the bend drawing (BP) displayed in the bend drawing display area (FD1), a product dimension display area (FD3) displaying the product's width ('W' in the drawing), length ('H' in the drawing), and material spacing dimension ('W1' in the drawing), a section number-by-section item display area (FD5) displaying the materials included in the product by section number, a variable display area (FD6) displaying variable values ​​in the bend drawing (BP) by section number, and an elevation drawing display area (FD7) displaying an elevation drawing in which section numbers are displayed separately.

[0036] The development drawing generation system (1000) inputs a bending drawing (BP) from the outside through the selection input window display area (FD4). Through this, the control unit (100) obtains the bending drawing (BP) and transmits it to the display unit (DS).

[0037] The display unit (DS) can display the bending drawing (BP) received in the bending drawing display area (FD1), and can receive the entire information of the product including the material corresponding to the bending drawing (BP) while receiving the bending drawing (BP). The entire information of the product can include the elevation drawing name and quantity displayed in the elevation drawing name and quantity display area (FD2), the product width and length dimensions and the material spacing dimensions displayed in the product dimension display area (FD3), the itemization information by section number displayed in the section number item display area (FD5), the variable values ​​in the bending drawing (BP) by section number displayed in the variable display area (FD6), and the elevation drawing (ED) including the material corresponding to the bending drawing (BP).

[0038] Accordingly, the bending drawing display area (FD1) of the display unit (DS) displays the bending drawing (BP) acquired by the control unit (100), and the elevation drawing name and quantity display area (FD2) displays the elevation drawing name and quantity of a product including a material corresponding to the corresponding bending drawing (BP).

[0039] The product dimension display area (FD3) displays the product's width, length, and material spacing dimensions.

[0040] The section number item display area (FD5) displays section number itemized information, such as the bend drawing name, width, length, quantity, and material, for each section number, and the variable display area (FD6) displays variable values ​​in the section number bend drawing (BP). The section number itemized information and variable values ​​may be previously stored information.

[0041] The elevation drawing display area (FD7) displays the elevation drawing (ED) of the entire product including the material corresponding to the obtained bend drawing (BP), and displays the elevation drawing (ED) with the section number indicated.

[0042] As an example, the control unit (100) can obtain the bend drawing (BP) of the product (Ganemo door in the drawing) with the section number '6'. Accordingly, the bend drawing (BP) corresponding to the section number '6' of the elevation drawing (ED) displayed in the elevation drawing display area (FD7) is displayed in the bend drawing display area (FD1) of the display unit (DS). The corresponding bend drawing (BP) can have, for example, a bend drawing name of 'Basic 12'.

[0043] Then, the control unit (100) performs a step of generating a 3D drawing (TP) based on the acquired bending drawing (BP). The control unit (100) can convert the 2D shape of the bending drawing (BP) into a 3D shape based on the width and length dimensions included in the bending drawing (BP). Accordingly, a 3D drawing (TP) based on the bending drawing (BP) is generated. The control unit (100) transmits the 3D drawing (TP) generated based on the bending drawing (BP) to the display unit (DS).

[0044] Then, the control unit (100) performs a step of generating a development drawing (PG) based on the 3D drawing (TP). The control unit (100) first generates a 3D drawing (TP) based on the bending drawing (BP), and then generates a development drawing (PG) based on the 3D drawing (TP).

[0045] The control unit (100) can generate a 3D drawing (TP) based on a bending drawing (BP) obtained therefrom, and generates a development drawing (PG) based on the 3D drawing (TP). Accordingly, even without manually creating the development drawing separately, a development drawing (PG) based on the dimensions of the bending drawing (BP) can be quickly generated.

[0046] When the control unit (100) creates a development drawing (PG) based on a 3D drawing (TP), it creates the development drawing (PG) based on dimensions that reflect the elongation rate based on dimensions included in the bending drawing (BP) that serves as the basis of the 3D drawing (TP). Accordingly, the development drawing (PG) includes dimensions that reflect the elongation rate based on the longitudinal (±x direction on the drawing) dimensions and the width direction (±y direction on the drawing) dimensions included in the bending drawing (BP).

[0047] One of the longitudinal (±x direction on the drawing) dimension and the width direction (±y direction on the drawing) dimension of the development drawing (PG) may be larger or smaller than the longitudinal (±x direction on the drawing) dimension and the width direction (±y direction on the drawing) dimension included in the bend drawing (BP) due to the elongation factor reflected therein.

[0048] As an example, the unfolded drawing (PG) generated by the unfolded drawing generation system (1000) of the present invention has the same width direction (±y direction on the drawing) dimension of the unfolded drawing (PG) as the length direction (±x direction on the drawing) dimension and width direction (±y direction on the drawing) dimension of the bending drawing (BP), and the length direction (±x direction on the drawing) dimension of some of the plurality of bending portions may be changed to be smaller or larger.

[0049] A development drawing (PG) is a drawing used when cutting and bending materials on site. It is a drawing that shows the bending area on a three-dimensional shape that is spread out on a single plane.

[0050] In other words, the development drawing (PG) is a flat drawing of the shape before bending. Therefore, the longitudinal (±x direction on the drawing) and transverse (±y direction on the drawing) dimensions in the development drawing (PG) must be displayed as dimensions that take into account the changes in the longitudinal (±x direction on the drawing) and transverse (±y direction on the drawing) dimensions of the material due to bending during the actual bending and manufacturing process.

[0051] The method for generating a development drawing of the present invention generates a development drawing (PG) based on a 3D drawing (TP), by calculating dimensions that take into account elongation based on the longitudinal (±x direction on the drawing) dimensions and the width direction (±y direction on the drawing) dimensions included in a bend drawing (BP) corresponding to the shape in which the material is actually bent, thereby generating the development drawing (PG). Accordingly, dimensions that take into account the bending of the material are indicated in the development drawing (PG), thereby improving work accuracy in the process of cutting the material.

[0052] Then, the control unit (100) transmits the 3D drawing (TP), the bending drawing (BP) that is the basis of the 3D drawing (TP), and the development drawing (PG) generated based on the 3D drawing (TP) to the display unit (DS). The development drawing (PG) includes dimensions that take into account the elongation ratio compared to the longitudinal (±x direction on the drawing) dimensions and the width direction (±y direction on the drawing) dimensions included in the bending drawing (BP).

[0053] When the control unit (100) transmits the development drawing (PG) to the display unit (DS), it can transmit work guide information together.

[0054] The work guide information includes the width direction (±y direction on the drawing) dimensions of the material, the bending start point, the bending part, the length direction (±x direction on the drawing) dimensions for each section classified according to the bending part, and the cumulative length direction (±x direction on the drawing) dimensions for each section from the bending start point to the section classified according to the bending part. Accordingly, the work guide information is displayed together on the development drawing (PG) displayed in the development drawing display area (FD9) of the display unit (DS).

[0055] The width direction (±y direction on the drawing) dimensions included in the work guide information, the length direction (±x direction on the drawing) dimensions for each section classified according to the bending area, and the cumulative length direction (±x direction on the drawing) dimensions for each section from the bending start point to the section classified according to the bending area may be dimensions calculated by considering the elongation compared to the length direction (±x direction on the drawing) dimensions and the width direction (±y direction on the drawing) dimensions included in the bending drawing (BP).

[0056] Referring to FIG. 4, the display unit (DS) receives a 3D drawing (TP), a bending drawing (BP), and a development drawing (PG) from the control unit (100), and can switch the first display window (DW1) to a second display window (DW2). The display unit (DS) can include a 3D drawing display area (FD8), a bending drawing display area (FD1), and a development drawing display area (FD9) in the second display window (DW2).

[0057] The display unit (DS) displays the 3D drawing (TP) received from the control unit (100) in the 3D drawing display area (FD8), displays the bending drawing (BP) in the bending drawing display area (FD1), and displays the unfolding drawing (PG) in the unfolding drawing display area (FD9).

[0058] The display unit (DS) can sequentially display the bending drawing (BP), the 3D drawing (TP), and the development drawing (PG) in the respective display areas (FD1, FD8, FD9). Alternatively, the display unit (DS) can simultaneously display the bending drawing (BP), the 3D drawing (TP), and the development drawing (PG) in the respective display areas (FD1, FD8, FD9).

[0059] The bend drawing (BP) displayed in the bend drawing display area (FD1) displays the longitudinal (±x direction on the drawing) and transverse (±y direction on the drawing) dimensions of the bent material together. In other words, the bend drawing (BP) includes the longitudinal (±x direction on the drawing) and transverse (±y direction on the drawing) dimensions of the bent material, as well as the bend start point ('start' on the drawing).

[0060] In the development drawing (PG) displayed in the development drawing display area (FD9), the work guide information received from the control unit (100) is displayed together.

[0061] More specifically, the development drawing (PG) displays the width direction (±y direction on the drawing) dimensions calculated by considering the elongation compared to the length direction (±x direction on the drawing) dimensions and width direction (±y direction on the drawing) dimensions included in the bend drawing (BP), the length direction (±x direction on the drawing) dimensions for each section classified according to the bending area, and the cumulative length direction (±x direction on the drawing) dimensions for each section from the bending start point to the section classified according to the bending area.

[0062] In addition, the bending start point is indicated by letters (dots and English 'start' on the drawing), and the bending portions are distinguished by numbers and indicated in numbered form (for example, numbers '0 to 9'). In this case, the planar shape of the developed drawing (PG) can have nine bending portions. The number '0' can mean the bending start point ('start' on the drawing).

[0063] The length direction (±x direction on the drawing) dimensions for each section classified according to the bending part, and the cumulative length direction (±x direction on the drawing) dimensions for each section from the bending start point to the section classified according to the bending part, are displayed on the development drawing (PG) and can also be displayed separately in the length display area (FD11) for each bending part.

[0064] As an example, the planar shape of the development drawing (PG) may be distinguished by the number '0', and the longitudinal dimension (±x direction on the drawing) from the bending start point ('start' on the drawing) to the first section may be 10 mm, and the cumulative longitudinal dimension (±x direction on the drawing) may be 10 mm.

[0065] In addition, the longitudinal dimension (±x direction in the drawing) from the first section to the second section may be 114, and the cumulative longitudinal dimension (±x direction in the drawing) from the bending start point ('start' in the drawing) to the second section may be 124 mm.

[0066] The longitudinal dimension (±x direction in the drawing) from the second section to the third section may be 26, and the cumulative longitudinal dimension (±x direction in the drawing) from the bending start point ('start' in the drawing) to the third section may be 150 mm.

[0067] The longitudinal dimension (±x direction in the drawing) from the third section to the fourth section may be 12, and the cumulative longitudinal dimension (±x direction in the drawing) from the bending start point ('start' in the drawing) to the fourth section may be 162 mm.

[0068] The longitudinal dimension (±x direction in the drawing) from the 4th section to the 5th section may be 16, and the cumulative longitudinal dimension (±x direction in the drawing) from the bending start point ('start' in the drawing) to the 5th section may be 178 mm.

[0069] The longitudinal dimension (±x direction in the drawing) from the 5th section to the 6th section may be 12, and the cumulative longitudinal dimension (±x direction in the drawing) from the bending start point ('start' in the drawing) to the 6th section may be 190 mm.

[0070] The longitudinal dimension (±x direction in the drawing) from the 6th section to the 7th section may be 26, and the cumulative longitudinal dimension (±x direction in the drawing) from the bending start point ('start' in the drawing) to the 7th section may be 216 mm.

[0071] The longitudinal dimension (±x direction in the drawing) from the 7th section to the 8th section may be 114, and the cumulative longitudinal dimension (±x direction in the drawing) from the bending start point ('start' in the drawing) to the 8th section may be 330 mm.

[0072] The longitudinal dimension (±x direction in the drawing) from the 8th section to the 9th section may be 10, and the cumulative longitudinal dimension (±x direction in the drawing) from the bending start point ('start' in the drawing) to the 9th section may be 340 mm.

[0073] Referring to Fig. 4, in the length display area (FD11) for each bending section, sections divided in numbered form may be listed. As an example, sections 1 to 9 may be listed.

[0074] In the length display area (FD11) for each bending section, the length direction (±x direction on the drawing) dimension for each section and the cumulative length direction (±x direction on the drawing) dimension from the bending start point to each section are displayed in an itemized manner.

[0075] The longitudinal dimension (±x direction on the drawing) of each section is the same as the longitudinal dimension (±x direction on the drawing) indicated on the plan view of the development drawing (PG), and the cumulative longitudinal dimension (±x direction on the drawing) up to each section is the same as the cumulative longitudinal dimension from the bending start point indicated on the plan view of the development drawing (PG) to each of the first to ninth sections.

[0076] In other words, in the length display area (FD11) for each bending section, the length direction dimension (±x direction on the drawing) for each section and the cumulative length direction dimension (±x direction on the drawing) from the bending start point to each section are displayed.

[0077] The control unit (100) can perform a step of obtaining cutting information after the step of generating a 3D drawing (TP).

[0078] Specifically, if the control unit (100) does not acquire cutting information after the step of generating the 3D drawing (TP), the control unit (100) can generate a development drawing (PG) by calculating dimensions that take into account the elongation based on the longitudinal (±x direction on the drawing) dimensions and the width direction (±y direction on the drawing) dimensions of the material included in the bending drawing (BP) based on the generated 3D drawing (TP) since there is no acquired cutting information.

[0079] In contrast, the control unit (100) can obtain cutting information after the step of generating a 3D drawing (TP).

[0080] Referring to FIGS. 4 and 5, the second display window (DW2) includes a cutting information display area (FD10). The cutting information display area (FD10) is composed of an upper cutting information display area (FD12) in which cutting information for the upper part of a three-dimensional shape included in a 3D drawing (TP) is input, and a lower cutting information display area (FD13) in which cutting information for the lower part of the three-dimensional shape is input.

[0081] Cutting information includes the cutting direction for the upper and lower parts of the 3D shape material included in the 3D drawing (TP), and the cutting angle with respect to the reference line when cutting according to the cutting direction.

[0082] Specifically, the cutting direction means a direction in which the upper part of a three-dimensional material is cut in one of the following directions: 'from left to right', 'from right to left', 'from top to bottom', or 'from bottom to top'. In addition, the cutting direction means a direction in which the lower part of a three-dimensional material is cut in one of the following directions: 'from left to right', 'from right to left', 'from top to bottom', or 'from bottom to top'.

[0083] The cutting angle refers to the angle formed by a straight line in the cutting direction with respect to the horizontal line running up and down in a three-dimensional shape as the reference line.

[0084] In the upper cutting information display area (FD12), the cutting direction at the top of the three-dimensional shape is input and the cutting angle is input and displayed. Referring to FIGS. 4 and 5, as an example, the cutting direction at the top of the three-dimensional shape may be 'from left to right' and the cutting angle may be 45°.

[0085] The control unit (100) can obtain cutting information input into the upper cutting information display area (FD12) displayed on the display unit. As an example, the control unit (100) can obtain the cutting direction from the left to the right at the top of the three-dimensional shape and obtain the cutting angle as 45°.

[0086] In the downward cutting information display area (FD13), the cutting direction at the bottom of the three-dimensional shape is input and the cutting angle is input and displayed. Referring to FIGS. 4 and 5, as an example, the cutting direction at the bottom of the three-dimensional shape may be 'from left to right', and the cutting angle may be 45°.

[0087] The control unit (100) can obtain cutting information input into the downward cutting information display area (FD13) displayed on the display unit. As an example, the control unit (100) can obtain the cutting direction at the bottom of the three-dimensional shape from left to right and obtain the cutting angle as 45°.

[0088] Then, the control unit (100) reflects the cutting direction and cutting angle at the upper part of the acquired 3D shape and generates a 3D drawing (TP) reflecting the cutting direction and cutting angle at the lower part of the acquired 3D shape.

[0089] Specifically, if the control unit (100) does not obtain cutting information, it can generate a 3D drawing (TP) based on the width direction (±y direction on the drawing) and length direction (±x direction on the drawing) dimensions included in the bending drawing (BP) and transmit the same to the display unit (DS).

[0090] When the control unit (100) obtains cutting information, it creates a 3D drawing (hereinafter referred to as a “basic 3D drawing”) based on the width direction (±y direction on the drawing) dimensions and the length direction (±x direction on the drawing) dimensions included in the bending drawing (BP), and creates a 3D drawing (hereinafter referred to as a “cut 3D drawing”) that reflects cutting information based on the basic 3D drawing (TP).

[0091] The control unit (100) generates a cut 3D drawing (CT) that divides a first area (F1) composed of a 3D shape in which cutting information is reflected on a basic 3D drawing (TP) and a second area (F2) corresponding to an area excluding the first area (F1) from the entire area composed of a 3D shape included in the basic 3D drawing (TP).

[0092] The cut 3D drawing (CT) includes a 3D shape divided into a first area (F1) consisting of a 3D shape in which cut information is reflected based on a 3D shape included in a basic 3D drawing (TP), and a second area (F2) consisting of an area excluding the first area (F1) from the entire area consisting of a 3D shape included in the basic 3D drawing (TP).

[0093] The control unit (100) transmits the generated cut 3D drawing (CT) to the display unit (DS).

[0094] The display unit (DS) displays a cut 3D drawing (CT) divided into a first area (F1) and a second area (F2) in the 3D drawing display area (FD8), and the first area (F1) and the second area (F2) can be displayed by distinguishing them with different colors.

[0095] The control unit (100) generates a cut 3D drawing (CT) and then performs a step of generating a development drawing (PG) corresponding to a 3D shape in which cut information corresponding to the first area (F1) is reflected.

[0096] The three-dimensional shape included in the first area (F1) is a shape created by reflecting cutting information (specifically, cutting direction and cutting angle) based on the three-dimensional shape included in the basic 3D drawing (TP), which is created based on the width direction (±y direction on the drawing) dimensions and length direction (±x direction on the drawing) dimensions included in the bending drawing (BP).

[0097] Accordingly, either the width direction (±y direction on the drawing) or the length direction (±x direction on the drawing) of the development drawing (PG) of the first area (F1) is different from the width direction (±y direction on the drawing) or the length direction (±x direction on the drawing) of the development drawing (PG) generated based on the 3D shape included in the basic 3D drawing.

[0098] As an example, the control unit (100) can obtain the cutting direction from the top and bottom of the three-dimensional shape included in the basic 3D drawing (TP) as 'from left to right' and obtain the cutting angle as 45°.

[0099] Accordingly, the top-to-bottom dimension of the three-dimensional shape forming the first area (F1) of the cut 3D drawing (CT) may be changed compared to the top-to-bottom dimension of the three-dimensional shape included in the basic 3D drawing (TP). The top-to-bottom dimension of the three-dimensional shape included in the basic 3D drawing (TP) may correspond to the width direction (±y direction on the drawing) dimension in the basic development drawing (PG).

[0100] The control unit (100) generates a cut development drawing (CP) based on the three-dimensional shape forming the first area (F1) and transmits it to the display unit (DS). The display unit (DS) displays the cut development drawing (CP) of the first area (F1) in the development drawing display area (FD9).

[0101] Referring to Fig. 5, a cut-out development drawing (CP) based on the first area (F1) is displayed in the development drawing display area (FD9). Since the cut-out development drawing (CP) is a development drawing generated based on the first area (F1) of the cut 3D drawing (CT), there is a difference in the width direction (±y direction on the drawing) or length direction (±x direction on the drawing) dimensions from the basic development drawing (PG). In the present invention, as an example, there is a difference in the width direction (±y direction on the drawing) dimensions between the cut-out development drawing (CP) and the basic development drawing (PG).

[0102] As an example, the planar shape of the cut development drawing (CP) may have the same dimensions as the planar shape of the basic development drawing (PG) in terms of the longitudinal dimension (±x direction on the drawing) for each section (sections 1 to 9) and the cumulative longitudinal dimension (±x direction on the drawing) from the bending start point to each section (sections 1 to 9).

[0103] Meanwhile, the cut development drawing (CP) is a plane shape generated by reflecting cutting information (cutting direction and cutting angle), and may differ from the width direction (±y direction on the drawing) dimension of the plane shape of the basic development drawing (PG).

[0104] Referring to Fig. 4, the width direction (±y direction on the drawing) dimension of each section (sections 1 to 9) of the plane shape of the basic development drawing (PG) generated based on the width direction (±y direction on the drawing) dimension and the length direction (±x direction on the drawing) dimension included in the bending drawing (BP) without reflecting the cutting information may be 576 mm.

[0105] Meanwhile, the plane shape of the cut development drawing (CP) generated by reflecting the cutting information may change in dimension compared to the width direction (±y direction on the drawing) dimension of the plane shape of the basic development drawing (PG) due to the cutting information.

[0106] Referring to Fig. 5, the plane shape of the cut development drawing (CP) may have changes in the width direction (±y direction on the drawing) dimension of the bending start point (number '0' on the cut development drawing (CP)) and the width direction (±y direction on the drawing) dimension in the 3rd to 9th sections compared to the width direction (±y direction on the drawing) dimension of each section in the basic development drawing (PG) due to the cutting information.

[0107] As an example, the dimension in the width direction (±y direction on the drawing) of the starting point of the bending of the plane shape of the cut development drawing (CP) (number '0' on the cut development drawing) can be changed to 556 mm.

[0108] The width direction (±y direction on the drawing) dimension of the third section of the planar shape of the cut development drawing (CP) can be changed to 524 mm. In addition, the width direction (±y direction on the drawing) dimensions of the fourth to ninth sections can be changed to 524, 492, 492, 440, 140, and 460 mm, respectively.

[0109] The cut-out development drawing (CP) does not include the development drawing for the second area (F2) of the cut-out 3D drawing (CT), and only includes the development drawing for the first area (F1).

[0110] The development drawing generation system (1000) of the present invention generates a cutting 3D drawing (CT) reflecting the cutting information when cutting information is input, and generates a cutting development drawing (CP) for a 3D shape deformed according to the cutting information compared to a 3D shape included in a basic 3D drawing (TP) based on a bending drawing (BP).

[0111] Accordingly, the development drawing generation system (1000) of the present invention can provide a highly accurate development drawing (cut development drawing (CP)) that takes into account the shape according to cutting information of materials to be used in an actual field. This can increase the accuracy of cutting and bending work of materials and improve work efficiency.

[0112] Meanwhile, unlike the development drawing generation system (1000) of the present invention, if a cutting development drawing (CP) cannot be generated, the material must first be cut according to the basic development drawing (PG) based on the three-dimensional shape included in the basic 3D drawing (TP) based on the bending drawing (BP) and not reflecting the cutting information, and then the material must be cut again according to the cutting information. Therefore, the work process including the process of cutting the material can be cumbersome.

[0113] However, the development drawing generation system (1000) of the present invention generates a cut development drawing (CP) of a first area (F1) composed of a three-dimensional shape in which cutting information is reflected. Accordingly, the material can be cut directly in accordance with the cutting information without first cutting the material in accordance with the basic development drawing (PG) based on the three-dimensional shape included in the basic 3D drawing (TP) in which cutting information is not reflected, and then performing a process of cutting the material again in accordance with the cutting information. In other words, the material cutting process can be simplified more efficiently.

[0114] In addition, the cut development drawing (CP) is a development drawing generated in response to the first area (F1) that reflects the cutting information in the 3D shape of the basic 3D drawing (TP) that reflects the elongation based on the width direction (±y direction on the drawing) and length direction (±x direction on the drawing) dimensions included in the bending drawing (BP). Therefore, since the width direction (±y direction on the drawing) and length direction (±x direction on the drawing) dimensions of the cut development drawing (CP) are dimensions that take the elongation into account, the accuracy of the work can be increased during the cutting work.

[0115] The control unit (100) can generate a cutting development drawing (CP), and then generate a work order (JO) composed of a bending drawing (BP), a cutting 3D drawing (CT) divided into first and second areas (F1, F2) with cutting information reflected therein, and a cutting development drawing (CP) of the first area (F1) formed of a three-dimensional shape with cutting information reflected therein.

[0116] Figure 6 illustrates an example work order (JO) generated by the control unit (100). The work order (JO) can be displayed on the display unit (DS) and can be output.

[0117] As described above, the present invention has been described with reference to preferred embodiments thereof, but it will be understood by those skilled in the art that various modifications or variations may be made to the present invention without departing from the spirit and scope of the present invention as set forth in the following claims.
