The present invention relates to a disassembly simulation of a nuclear power facility, and is intended to calculate the time required to actually perform a cutting process performed during the disassembly simulation.

In general, nuclear dismantling is a costly and time-consuming and dangerous process. Therefore, it is essential to optimize through simulation to save costs and time, and to evaluate the safety of the process in advance to improve safety.

On the other hand, the dismantling process of nuclear facilities may include a cutting process for cutting large structures.

Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the accompanying drawings.

1 is a block diagram for explaining a structure of a cutting time required time calculating apparatus 100 according to an embodiment of the present invention.

1, the apparatus 100 for calculating a time required for cutting according to an embodiment of the present invention includes a control unit 102, an input unit 104 connected to the control unit 102, a display unit 106, and a memory 108 ). The components shown in FIG. 1 are not essential for implementing the cutting time required time calculating apparatus 100 according to the embodiment of the present invention, so that the cutting time required time calculating apparatus 100 described in the present specification is the same as the above- May have more or fewer components than the < / RTI >

More specifically, among the above components, the input unit 104 receives information from a user. When the information is input through the input unit 104, the control unit 102 controls the operation of the input unit 104, It is possible to perform the process of calculating the time. The input unit 104 may include a mechanical input means (or a mechanical key, e.g., a plurality of buttons, a dome switch, a jog wheel, a jog switch, etc.) . For example, the touch-type input means may comprise a virtual key, a soft key or a visual key displayed on the touch screen through software processing, And a touch key disposed on the touch panel.

On the other hand, the display unit 106 can display (output) the information processed in the cutting time required time calculating apparatus 100 according to the embodiment of the present invention. For example, the display unit 106 can be displayed in a UI (User Interface) or GUI (Graphic User Interface) form according to various information displayed during execution of the cutting process simulation and an execution screen of the cutting process simulation.

In addition, the display unit 106 may include a touch sensor that senses a touch to the display unit 106 so that a control command can be received by a touch method. When a touch is made to the display unit 106, the touch sensor senses the touch, and the control unit 102 generates a control command corresponding to the touch based on the touch. The content input by the touch method may be a letter or a number, an instruction in various modes, a menu item which can be designated, and the like.

As described above, the display unit 106 may have a mutual layer structure with the touch sensor or may be integrally formed to realize a touch screen. The touch screen functions as the input unit 104 that provides an input interface between the cutting process time required device 100 and the user and also serves as an output interface between the cutting process time required device 100 and the user .

The memory 108 may also store at least one program for operation of the control unit 102 and may store data to be input / output (e.g., information relating to the object to be cut or information relating to the profile of the cutting equipment, The thickness information of the object to be cut calculated in the process of calculating the time required for the total cutting process, and the like) may be temporarily stored.

In addition, the memory 108 may store various information related to the simulation of the cutting equipment. For example, the memory 108 may contain various information about a plurality of different cutting equipment. Here, the information of the cutting equipment may include information relating to a cutting tool used in the cutting equipment and a cutting shape formed according to the cutting tool. For example, if the cutting equipment is a band saw equipment, the cutting equipment may use a saw in the form of a band as a cutting tool. In this case, in view of the characteristics of the cutting tool 'band saw', the cutting equipment may have a linear cutting shape, so that two points for defining the cutting shape of the linear cutting shape can be cut by the cutting equipment ' Equipment ', that is, profile information.

The profile information may also include information on the tool transporting method for transporting the cutting tool according to the characteristics of the cutting tool used in each cutting equipment. For example, the band saw equipment can cut the object to be cut while moving the cutting tool 'band saw' in the vertical direction. Therefore, the feeding path of the cutting tool according to the tool feeding method of the band saw equipment can be determined as the vertical direction of the cutting tool 'band saw', that is, the vertical direction. Hereinafter, for each of a plurality of different cutting equipment, information on a plurality of points for defining each cutting shape and information on the cutting path of each cutting tool is stored in the memory One part of the memory 108 or one area on the memory 108 will be referred to as a 'profile storage part 110'.

As described above, the apparatus for calculating the time required for cutting according to the embodiment of the present invention has been described to reflect the influence of the material and the thickness of the object to be cut in order to accurately calculate the required time. To this end, the memory 108 may include information about the cutting speeds when the cutting tool used in each cutting equipment cuts the object of cutting of different materials. And information on the tool feed rate at which each cutting tool can be fed, according to the speed at which the cutting tool can cut and move, that is, the material and thickness of the object to be cut, according to the cutting speed and the thickness of the object to be cut can do. Hereinafter, one part of the memory 108 in which the conveying speed information for conveying the cutting tool is stored, or one area on the memory 108 is referred to as a " tool conveying speed storing part 112 " .

Meanwhile, the control unit 102 may control other connected components. When the object to be cut and the cutting equipment are selected, the control unit 102 can calculate the time required to cut the object to be cut according to the characteristics of the selected cutting equipment. For this, the controller 102 may read information on the tool transfer method according to the currently selected cutting equipment from the profile storage unit 110 of the memory 108, when the object to be cut and the cutting equipment are selected. And determine the path through which the cutting tool is to be transferred in the currently selected cutting tool according to the acquired tool transfer method.

On the other hand, the control unit 102 may obtain information on a plurality of points for defining the cut shape of the currently selected cutting equipment from the profile information of the currently read cutting equipment. The cut shape of the currently selected cutting equipment can be defined from the obtained plurality of point information.

The control unit 102 may generate a plurality of checkpoints formed at regular intervals along the determined conveyance path. Then, the cut shape is generated for each check point, and a predetermined object (hereinafter, referred to as a solid object) may be generated based on the generated cut shapes. The thicknesses of the cut objects corresponding to the respective checkpoints can be calculated from the solid objects superimposed on the cut target object through a Boolean operation between each of the generated solid objects and the cut target object. Based on the thicknesses of the objects to be cut corresponding to the respective checkpoints, the cutting tool conveyance speeds at the respective checkpoints are calculated, and the required time between the checkpoints can be calculated based on the calculated conveyance speeds. By summing up the calculated times, it is possible to calculate the time required for cutting the currently selected cutting object using the currently selected cutting equipment.

FIG. 2 is a flowchart showing in detail each operation step of calculating the time required for the cutting process in the cutting time required time calculating apparatus 100 according to the embodiment of the present invention. 3 is a diagram illustrating an example of a band saw apparatus that can be selected as a cutting apparatus in the apparatus 100 for calculating a time required for cutting according to an embodiment of the present invention.

The control unit 102 of the apparatus 100 for calculating the time required for cutting according to the embodiment of the present invention can select the object to be cut and the object to be cut through the input unit 104. [ For example, the control unit 102 may select a specific object to be cut and a cutting target equipment directly from the user. Alternatively, the object to be cut and the object to be cut can be selected on the basis of a cutting process simulation made separately or in accordance with the cutting simulation included in the nuclear disassembly simulation. When the object to be cut and the object to be cut are selected, the process of calculating the time required for cutting according to the embodiment of the present invention can be started.

When the object to be cut and the cutting equipment are selected, the control unit 102 can first obtain information on the transfer method of the cutting tool from the profile information corresponding to the selected cutting equipment. Then, a transfer path through which the cutting tool is moved may be determined according to the movement of the cutting equipment from the acquired tool transfer method (S200).

Referring to FIG. 3, FIG. 3 shows an example of the band saw equipment 300. In the following description, the band saw apparatus 300 will be described as an example of a cutting apparatus used in a process of calculating a time required for a cutting process according to an embodiment of the present invention. However, even in the case of using various cutting equipment having any other type of cutting equipment or a cutting shape having a more complicated shape (a cutting shape having three or more points for generating a cutting shape, which will be described below) It goes without saying that the present invention can be applied. In other words, it is needless to say that the description of the band saw apparatus in the following description is merely for simplifying the explanation, and the present invention is not limited thereto.

As shown in FIG. 3, the band saw equipment 300 includes a band-shaped saw that is coupled to two rotary shafts in the form of a band, and a cutting device that cuts the object with a cutting force generated while moving at high speed in accordance with the rotation of the rotary shafts . ≪ / RTI >

Therefore, the band saw equipment 300 can cut the object to be cut by the band-shaped top portion 302 exposed to the outside. Therefore, as shown in FIG. 3, the cutting target 340 can be cut while vertically moving the saw-shaped top portion 302 exposed to the outside from the cutting target 340 vertically downward. In this case, the tool transporting method of the band saw apparatus 300 may be a vertical movement 330, and the path through which the cutting tool of the band saw apparatus 300 is transported may be such that the object to be cut 340 is vertically passed (340). ≪ / RTI >

On the other hand, as shown in FIG. 3, the band saw equipment 300 can cut the object to be cut with the band-shaped top portion 302 exposed to the outside. Therefore, the cut shape of the band saw equipment 300 may have a straight cut shape 320, as shown in FIG. Also, when the cut shape 320 is linear, the cut shape 320 can be defined by only two points, that is, the start point 312 and the end point 314. The information of the start point 312 and the end point 314 may be included in the profile storage unit 110 of the memory 108 as profile information for the band saw equipment 300.

Meanwhile, as shown in FIG. 3, when the feed path of the cutting tool according to the currently selected cutting equipment is determined, the control unit 102 can generate n checkpoints at regular intervals with respect to the feed path of the generated cutting tool ( S202). Here, the number n of checkpoints may be formed according to an interval between checkpoints set by the user. Alternatively, the number n of the checkpoints may be a predetermined number from the user.

On the other hand, when n checkpoints are generated, the control unit 102 can generate a cut shape corresponding to the profile information of the currently selected cutting equipment for each generated check point (S204). For example, when the currently selected cutting equipment has a straight cut shape like the band saw equipment 300, the control unit 102 generates the straight cut shape for each of n checkpoints through each check point can do.

For example, the control unit 102 generates a starting point for defining a cutting shape from the profile information of the currently selected cutting equipment at a position where movement of the cutting tool starts, that is, at a feeding start position of the cutting tool in accordance with the movement of the cutting equipment . And generate a transport path through which the cutting tool is moved from the created starting point through the cutting equipment. In step S202, the control unit 102 may generate n checkpoints on the generated transfer path.

In this case, the control unit 102 may set each check point generated on the conveyance path to the start points defined in the profile information of the cutting equipment. The control unit 102 may form end points corresponding to the set start points, and may generate straight line cut shapes connecting the start points and the end points. Thus, for each check point created on the transport path, the cut shape defined in the profile information of the currently selected cutting equipment can be generated.

Meanwhile, if a cut shape is generated for each check point in step S202, the controller 102 may calculate the thickness of each position of the cut object corresponding to each check point (S206). For example, the control unit 102 can obtain the length of each of the portions overlapping the object to be cut out of the cut shapes corresponding to the respective check points. By summing the obtained lengths, the thickness of each position of the object to be cut corresponding to each check point can be calculated.

In step S206, the control unit 102 generates a predetermined virtual object (hereinafter, referred to as a solid object) to obtain the length of each of the portions overlapping the object to be cut out of the cut shapes corresponding to the check points , And the length of each portion of the cut shape corresponding to each check point, which is superimposed on the cut object, may be obtained by using the volume of the portion where the generated solid object and the cut object overlap each other.

In this case, a platform for performing a disassembly process simulation or a cutting process simulation, or a device for storing a program or an application capable of calculating a time required for a cutting process according to the embodiment of the present invention, The thickness of the object to be cut corresponding to each check point may be directly calculated from the volume sum of the overlapping portions.

The process of calculating the thicknesses of the object to be cut corresponding to each check point according to the embodiment of the present invention through a device or a platform having a function of calculating the volume sum of at least one virtual object will now be described with reference to FIG. Will be described in more detail.

Meanwhile, if the thickness of the object to be cut is calculated for each of the n checkpoints in step S206, the controller 102 may calculate the feed rate of the cutting tool for each of the n checkpoints (S208). Here, the tool conveying speed may mean a speed at which the cutting tool of the currently selected cutting tool cuts and moves the cutting target object according to the material and thickness of the currently selected cutting target object. Therefore, even if the material of the object to be cut is the same, the tool conveying speeds calculated for each of the n checkpoints may differ from each other when the thicknesses of the object to be cut calculated at the n checkpoints are different from each other.

The information on the tool conveyance speeds that are different depending on the thickness may be included in the tool conveyance speed storage unit 112 of the memory 108. That is, the tool feed rate storage unit 112 may include information on the feed speed of the tool for various cutting thicknesses of various materials in the form of a table (thickness-feed rate table) 102 can obtain the tool feed rate corresponding to each check point from the thickness-feed rate table corresponding to the material of the currently selected cutting tool and the currently selected cutting target object.

On the other hand, the control unit 102 may calculate the tool transfer time according to the distance between each check point, based on the tool transfer speed for each check point obtained in step S208 (S210). For example, the control unit 102 may calculate the time at which the cutting tool moves from each check point to the next check point, based on the tool feed rate calculated for each check point. Since the n checkpoints are formed at equal intervals, the distance from the checkpoint to the next checkpoint may be the same.

On the other hand, if the tool transfer times during which the cutting tool moves between the respective check points are calculated, the control unit 102 may sum the calculated tool transfer times (S212). The result of summing the tool transport times may be the time required for cutting the object to be cut by the cutting equipment.

As described above, according to the present invention, a predetermined virtual object is formed according to each check point, and thicknesses of object to be cut corresponding to each check point can be calculated using the formed virtual object have. In this case, when calculating the time required for cutting according to the embodiment of the present invention through a device or a platform having a function of calculating a volume sum of at least one virtual object such as a CAD (Computed Aided Design) system, The thickness of the object to be cut corresponding to each check point can be accurately calculated.

FIG. 4 is a flowchart illustrating a process of calculating a time required for a cutting process according to an embodiment of the present invention, using an apparatus or a platform having a function of calculating a volume sum of at least one virtual object, The thickness of the object to be cut corresponding to the check point is calculated.

Referring to FIG. 4, when a cut shape is generated according to the profile information for each of a plurality of check points in the operation procedure of FIG. 3, In step S400, circles having predetermined radiuses on a plane perpendicular to the cut shape generated by the points according to the profile information may be generated centering on each of them. Here, the circles may be generated so as to have the predetermined radius around the contact point between the plane perpendicular to the cut shape and the cut shape. For example, as described above, if the cut shape according to the currently selected cutting equipment is a linear shape defined by the start point and the end point included in the profile information, the control unit 102 controls the start point and the end point, It is possible to generate circles having the predetermined radius on the plane perpendicular to the cut shape of the circle.

In operation S402, the control unit 102 may generate a solid object for each of the n checkpoints based on the circles created in step S400 and the straight line shape defined by the start point and the end point. For example, the solid object may have a bottom surface and a top surface formed as a circle having the predetermined radius. That is, the solid object may be a cylindrical solid object having a thickness of the diameter of the circle forming the bottom surface or the top surface, which is twice the predetermined radius about the cut shape of the linear shape.

On the other hand, these cylindrical solid objects can be generated at each of the n checkpoints. That is, the cylindrical solid object may be formed to correspond to each of the n checkpoints. When a plurality of cylindrical solid objects are generated as described above, the control unit 102 may perform a Boolean operation on the generated cylindrical solid objects and the object to be cut (S404).

Here, the control unit 102 may erase parts of the cylindrical solid object except the part where the cylindrical solid objects and the cut object overlap each other through the Boolean operation. Accordingly, when the Boolean operation in step S404 is performed, the remaining parts of each cylindrical solid object may be parts overlapping the object to be cut.

Then, the control unit 102 may calculate the sum of the volumes of the remaining parts for each cylindrical solid object (S406). In this case, by using the function of the apparatus or the platform configured to operate the program or the application that calculates the time required for the cutting process according to the embodiment of the present invention, the volume sum of the remaining parts in each cylindrical solid object Can be calculated. For example, when the device or platform is based on a CAD system, a volume sum of the remaining parts of each cylindrical solid object is calculated as the volume of the remaining parts based on the volume sum calculation command or function defined in the CAD system .

Meanwhile, the controller 102 may calculate the length of the cylindrical solid object corresponding to the volume of the cylindrical solid object remaining parts for each of the cylindrical solid objects (S408). For example, in step S408, the controller 102 divides the length component of the cylindrical solid object corresponding to the calculated volume into the remaining part (s) by dividing the volume of the remaining parts by the area of the circle having the predetermined radius, The length of the cylindrical solid object corresponding to the volume of the cylindrical solid object.

While the remaining portions of the cylindrical solid object may be portions overlapping the object to be cut at a particular checkpoint corresponding to the cylindrical solid. Accordingly, the length component of the cylindrical solid object obtained from the volume of the cylindrical solid object remainder portions may be the sum of lengths of the respective portions where the cylindrical solid object overlaps the object to be cut. Therefore, the length component of the cylindrical solid object obtained from the volume of the remaining portions of the cylindrical solid object may be the thickness of the object to be cut at a specific check point corresponding to the cylindrical solid object. Accordingly, the controller 102 may calculate the length components of each cylindrical solid object calculated in step S408 as the cut object thicknesses at the check points corresponding to each cylindrical solid object (S410).

If the cut thicknesses at the respective check points are calculated through the process of FIG. 4, the control unit 102 determines the tool feed speed at each check point based on the cut target thickness in step S208 of FIG. .

4, the radius of the circle may be determined so that the circles generated on the surface perpendicular to the cut shape in step S400 may have predetermined widths. For example, the radius R of the circle can be determined through the following equation (1).

Here, the units of R may be unified in the unit of the length of the cylindrical solid object to be obtained (for example, mm or cm). Then, as defined in Equation (1), if the radius R of the circle is determined, the width of the circle forming the bottom surface or the top surface of the cylindrical solid may be '1'.

In this case, from the remaining part volume of the cylindrical solid object having the bottom surface or the top surface formed according to the radius R, the calculation amount of the step S408 of FIG. 4 for calculating the length of the cylindrical solid object can be further reduced, The thickness to be cut at each check point can be calculated.

2, the present invention calculates the thickness of the object to be cut for each of the n checkpoints formed on the conveyance path, and calculates the tool conveying speed at each check point based on the calculated thickness , And the time at which the cutting tool is moved between each check point can be calculated according to the calculated tool feed rate. Accordingly, the time at which the cutting tool is moved between the check points can be determined according to the thickness of the object to be cut calculated at each check point.

Therefore, as the number of checkpoints generated increases, the thickness of the object to be cut is calculated at narrower intervals, so that it is possible to more accurately calculate the time required for the cutting process. However, the larger the number of checkpoints, the larger the amount of computation required to calculate the time required for the cutting process. On the other hand, the smaller the number of checkpoints, the smaller the amount of computation can be obtained by calculating the thickness of the object to be cut at a wider interval, but the error from the actual cutting process can be increased.

As described above, according to the present invention, it is possible to obtain the thickness of the object to be cut at each check point by creating circles formed with predetermined radii at each check point and creating cylindrical solid objects using the circles have. Therefore, if each checkpoint is formed at equal intervals according to the distance corresponding to the diameter of the cylindrical solid, then all the parts of the object to be cut can be divided into the cylindrical solid objects Lt; / RTI >

That is, the interval between the cylindrical solid objects can be set to '0'. Accordingly, when considering both the accuracy and the computation amount, it is possible to calculate the thickness of the object to be cut most efficiently at each check point. Therefore, when the circle forming the bottom surface or the top surface of the cylindrical solid object has the radius R defined by Equation (1), the distance T between the respective checkpoints is expressed by the following equation Can be determined to be twice the radius (R) defined by Equation (1), i.e., 2R, as shown in Equation (2).

In the above description, the operation process of calculating the time required for performing the simulation of the cutting process according to the embodiment of the present invention has been described in detail with reference to a plurality of flowcharts.

Hereinafter, the process of calculating the time required for the cutting process according to the embodiment of the present invention will be described in more detail with reference to a plurality of exemplary views.

FIG. 5 is an exemplary diagram illustrating a process of calculating the time required for the cutting process performed according to an embodiment of the present invention when a cutting process is performed on an object to be cut.

The control unit 102 may generate a cut shape for cutting the object 500 to be cut, as shown in FIG. 5 (b). The control unit 102 reads information for defining the cut shape of the currently selected cutting equipment from the profile storage unit 110, and can generate a cut shape from the read information. Therefore, if the currently selected cutting equipment is a band saw equipment, the start point 512-1 and the end point 514-1 information is read from the profile storage unit 110, and based on the initial position of the cutting equipment, , The cut shape 516-1 corresponding to the read starting point 512-1 and the end point 514-1 can be generated.

On the other hand, the control unit 102 can determine the path along which the cutting tool is fed according to the cutting tool feeding method of the currently selected cutting equipment. That is, as shown in FIG. 5 (b), if the tool is fed so as to cut the object to be cut in the vertical direction by the tool feeding method of the cutting tool, As shown in the transfer path 510 of FIG.

In this case, as shown in FIG. 5C, the control unit 102 can form the conveying path 510 via the starting point 512-1. Then, as shown in FIG. 5C, the conveying path 510 may be formed in the vertical direction via the starting point 512-1.

When the conveying path 510 is formed as described above, the control unit 102 may form n checkpoints with respect to the conveying path 510. Therefore, check points from 1 to n can be generated on the conveyance path. Then, the control unit 102 sets each check point generated on the conveyance path 510 as a start point and generates an end point corresponding to the set start point. Based on the generated start and end points, linear cut shapes can be generated 516-1 through 516-n for each of the n checkpoints.

On the other hand, when a cut shape is generated for each of the n checkpoints, the control unit 102 can calculate the thickness of the object to be cut corresponding to each of the n checkpoints. In order to calculate the thickness of the object to be cut, as shown in FIG. 4, a cylindrical object may be created and the generated cylindrical object may be used.

FIG. 6 is an exemplary diagram illustrating a process of calculating the thickness of a cutting target object from any one of a plurality of checkpoints according to an embodiment of the present invention when a cutting process is performed on the object to be cut. 5, the process of calculating the thickness 600 of the object to be cut corresponding to the specific check point i at a specific check point (i) among the check points shown in FIG. 5 is described as an example I will explain it.

Referring to FIG. 6A, when a specific check point (i) 602 is set as a start point for defining a cut shape, a cut shape (i) is formed along an end point 604 corresponding to a set start point 620 606 may be generated. In this state, the control unit 102 displays a first circle 612 having a predetermined radius (R) and a second circle 612 having a predetermined radius (R) on a plane perpendicular to the cut shape 606 with the start point 602 and the end point 604 as a center. A two-circle 614 can be generated.

If the first circle 612 and the second circle 614 are formed as described above, the controller 102 controls the first circle 612 and the second circle 614 And generate a cylindrical solid object 620 based thereon. Wherein the cylindrical solid object 620 may be generated along the cut feature 606 about the cut feature 606. Thus, if the cut feature 606 has a shape such as a polygon or an arc rather than a straight shape, then a cylindrical solid object centered on the cut feature 606 may have a cut feature 606 having a polygonal or arcuate shape As shown in FIG.

6, when the cylindrical solid object 620 is generated, the controller 102 controls the cylindrical solid object 620 and the cut object object 620 as described in step S406 of FIG. 500). ≪ / RTI > In this case, the Boolean operation may be performed in such a manner as to erase the non-overlapping portion from the cylindrical solid object 620 with the cut object 500. 6 (c), only the portions 630, 632, 634, and 636 overlapping the cutting target object 500 from the cylindrical solid object 620 can be left have.

On the other hand, as shown in FIG. 6C, by the Boolean operation, the remaining portions 630, 632, 634, and 632 of the cylindrical solid object 620, which are not overlapped with the object 500 to be cut, 636 are generated, the control unit 102 may calculate the sum of the volumes of the remaining portions 630, 632, 634, 636. [ Here, the control unit 102 may select each of the remaining portions 630, 632, 634, and 636 as a volume calculation target and calculate a volume sum of the selected portions according to a predefined volume calculation function.

On the other hand, when the sum of the volumes of the remaining portions 630, 632, 634, and 636 is calculated, the controller 102 divides the calculation result by the width of the first circle 612 or the second circle 614, The length of the cylindrical solid object corresponding to the sum of the volumes can be obtained. Then, the length of the obtained cylindrical solid object may be the thickness of the object to be cut corresponding to the specific check point (i: 602).

Meanwhile, although FIG. 6 illustrates a specific checkpoint, the process of FIG. 6 may be performed for each of a plurality of checkpoints. Therefore, the thickness of the object to be cut corresponding to each check point can be calculated, and the calculated thickness can be used to determine the cutting tool conveying speed at each check point.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Particularly, in the embodiment of the present invention, an example of using a band saw apparatus as a cutting apparatus has been described as an example in which the cutting shape is linear according to a 'band saw' which is a cutting tool of the band saw apparatus, It goes without saying that the present invention is not limited thereto.

That is, in the case of other cutting tools, the cutting shape may have a polygonal shape or an arc shape instead of a straight shape. In this case, two or more points for defining the cut shape may be included in the profile information corresponding to the cutting equipment. A cut shape having the polygon or arc shape may be generated according to two or more points included in the profile information, and a feed path may be generated according to a cutting tool feeding method of the cutting equipment.

Cutting shapes having the polygonal or arcuate shape corresponding to each of the n checkpoints generated according to the generated transfer path can be generated. A cylindrical solid object having a predetermined bottom or top width along the cut shapes Of course. Therefore, a pipe-shaped (cylindrical) solid object having a polygonal curvature or an arc-shaped curvature can be created, and the calculation and volume calculation of the curvature or warped pipe-like solid objects and the object to be cut, The thicknesses of the object to be cut corresponding to each check point can be calculated.
