That is, the arithmetic circuit 64 can be realized by various processors such as GPU, FPGA, DSP, ASIC, etc., in addition to CPU and MPU. Such an arithmetic circuit 64 is composed of, for example, a signal processing circuit which is a semiconductor integrated circuit.

(Operation of terminal device)
Processing executed by the arithmetic circuit 64 of the terminal device 6 will be described. The arithmetic circuit 64 of the terminal device 6 is configured to execute acquisition processing, transmission processing, reception processing, and output processing.

Acquisition processing is processing for acquiring the three-dimensional object information D<b>11 by the input/output device 61 . The arithmetic circuit 64 may store the three-dimensional object information D<b>11 in the storage device 63 after acquiring the three-dimensional object information D<b>11 . In the acquisition process, for example, the input/output device 61 presents a screen for inputting the three-dimensional object information D11, and the requester can input the three-dimensional object information D11 according to the instructions on the screen. The three-dimensional object information D11 can be input not only by inputting the three-dimensional object information D11 from an external device to the terminal device 6, but also by specifying data to be used as the three-dimensional object information D11 from data stored in the terminal device 6. may contain. The transmission process can input the three-dimensional object information D<b>11 acquired in the acquisition process to the manufacturing execution system 2 via the communication circuit 62 .

The receiving process is a process of receiving the corrected three-dimensional object information D<b>13 generated by the manufacturing execution system 2 from the manufacturing execution system 2 via the communication circuit 62 . The arithmetic circuit 64 may store the corrected three-dimensional object information D13 in the storage device 63 upon receiving the corrected three-dimensional object information D13. The output process is a process of presenting the corrected three-dimensional object information D13 received in the reception process by an input/output device. In the output process, for example, a screen for outputting the corrected three-dimensional object information D13 is presented by the input/output device 61, and the client sees the screen to understand the three-dimensional object shape indicated by the corrected three-dimensional object information D13. be able to. The requester can confirm the corrected three-dimensional object information D13 through the terminal device 6 by the receiving process and the outputting process.

The arithmetic circuit 64 causes the input/output device 61 to display a screen asking whether the client approves the production of the three-dimensional object in response to the presentation of the corrected three-dimensional object information D13. 2, the manufacturing execution system 2 is notified through the communication network 72 that the client has approved the manufacturing of the three-dimensional object. In this way, the arithmetic circuit 64 of the terminal device 6 presents the requester with the shape indicated by the information included in the corrected three-dimensional object information D13 acquired in the reception process, and obtains the requester's approval for manufacturing with that shape. be able to. Further, in this manner, the arithmetic circuit 64 can notify the manufacturing execution system 2 that approval by the client has been obtained.

In this way, when the shape of the three-dimensional object is corrected in the information processing system 2A and the shape of the three-dimensional object to be manufactured changes, the client can confirm the corrected shape through the terminal device 6 . Accordingly, when the three-dimensional object shape is corrected, the client can confirm the corrected shape and request the production of the three-dimensional object.

(Operation of Manufacturing Execution System)
Processing executed by the arithmetic circuit of the manufacturing execution system 2 will be described. The arithmetic circuit 24 of the manufacturing execution system 2 is configured to execute storage processing, determination processing, information adjustment processing, selection processing, and execution processing.

The storage process is a process of receiving the three-dimensional object information D11 through the interface device (the input/output device 21 and the communication circuit 22) and storing it in the storage device 23. FIG. In the manufacturing execution system 2, the three-dimensional object information D11 can be input using the input/output device 21 and the communication circuit 22. FIG. In this embodiment, the manufacturing execution system 2 is communicably connected to the terminal device 6 through the communication network 72 by the communication circuit 22 . The manufacturing execution system 2 can acquire the three-dimensional object information D11 produced by the terminal device 6 or the three-dimensional object information D11 input to the terminal device 6 from the terminal device 6 .

The determination process is a process of determining the three-dimensional object manufacturing process based on the three-dimensional object information D11 and generating the manufacturing process information D14. The determination process specifies a plurality of steps (one or more first steps and one or more second steps) necessary for manufacturing a three-dimensional object based on the three-dimensional object information D11, and determines the order of the plurality of steps. The determination process determines the manufacturing process by adding a quality confirmation process and a transportation process according to the plurality of processes whose order has been determined. For example, it is assumed that the manufacture of a three-dimensional object requires a step of forming a modeled object from a resin material with a 3D printer and a step of surface-treating the modeled object with a surface treatment device. In this example, the former process is specified as the first process, and the latter process is specified as the second process. Since the execution of the second process requires the completion of the first process, the order of the first process and the second process is such that the first process comes first and then the second process. A first quality confirmation step and a first transportation step are attached to the first step, a second quality confirmation step and a second transportation step are attached to the second step, and the first step, the first quality confirmation step, the second A manufacturing process is obtained in which the first transportation step, the second step, the second quality confirmation step, and the second transportation step are executed in order.

In the information adjustment process, based on the one or more second steps of the manufacturing process determined in the determination process, the three-dimensional object information D11 is added to the modeled object information having information for determining the target shape of the result of the first step. This is the process of converting to D12. The three-dimensional object shape indicated by the three-dimensional object information D11 acquired by the terminal device 6 through the acquisition process may be deformed by one or more predetermined processes in the second step determined in the manufacturing process. If the manufacturing process is executed without considering such deformation, a three-dimensional object having a shape different from the three-dimensional object assumed by the client may be produced. Therefore, the information adjustment process adjusts the shape of the three-dimensional object so as to compensate for the shape change in the predetermined process so that the predetermined shape becomes a three-dimensional object shape when deformed by one or more predetermined processes based on the second step. , the predetermined shape is determined based on the shape of the three-dimensional object. Thereby, the information adjusting process generates the modeled object information D12 having information for determining the target shape (that is, the predetermined shape) of the result of the first step. As a result, the arithmetic circuit 24 can execute processing in the manufacturing execution system 2 so that there is no difference between the three-dimensional object indicated by the information included in the three-dimensional object information D11 and the product after the manufacturing process is finished.

Adjustment of the three-dimensional object shape by information adjustment processing is not limited to compensation for shape change by one or more predetermined processes in the second step. It may be configured such that a fixed shape for fixing in a predetermined process can be added to the three-dimensional object shape. Further, in the information adjustment process, in one or more predetermined processes of the second step, a modeled object and an auxiliary tool separate from the modeled object are installed in order to fix the modeled object modeled in the first step. A target shape of the result of the first step may be determined as formed in the first step. In the information adjustment process, the details of the process performed when converting the three-dimensional object information D11 into the modeled object information D12 are stored in the storage device 23 as adjustment information D16.

The three-dimensional object information D11 may have information indicating a shape that is not suitable for manufacturing with equipment based on one or more first steps of the manufacturing process determined in the determination process. Even when such three-dimensional object information D11 is acquired, the manufacturing system 1 can automatically correct the shape to a shape suitable for manufacturing in the equipment of the first step. To perform such correction, the information adjustment process may include a determination process, a correction process, and an adjustment process.

The determination process is a process of determining whether or not the three-dimensional object shape indicated by the information of the stored three-dimensional object information D11 is suitable for manufacturing by the equipment in the first step (details will be described later). If the three-dimensional object information D11 is not suitable for manufacturing by the equipment in the first step, the arithmetic circuit 24 executes correction processing. If the three-dimensional object information D11 is suitable for manufacturing by the equipment of the first step, the arithmetic circuit 24 executes adjustment processing.

The correction process is a process of correcting the three-dimensional object shape so that it becomes a shape suitable for production in the first process when the three-dimensional object shape is not suitable for manufacturing in one or more first processes (details will be described later). do). For example, if the dimension of the three-dimensional shape is too small to be manufactured by the equipment of the first process of the manufacturing process determined by the determination process, the arithmetic circuit 24 can be manufactured by the equipment of the first process by the correction process. Change the shape of the three-dimensional object so that it becomes the size. In the correction process, corrected three-dimensional object information D<b>13 having information indicating the shape obtained by correction is stored in the storage device 23 . Thus, when obtaining the client's approval as described above, the arithmetic circuit 64 presents the corrected three-dimensional object information D13 to the input/output device 61 of the terminal device 6 so that the client can determine the shape of the three-dimensional object to be produced. can be easily verified.

When executing the determination process, the adjustment process is performed on the three-dimensional object shape indicated by the information included in the three-dimensional object information D11, or on the shape indicated by the information included in the corrected three-dimensional object information D13 generated by the correction processing. This is a process for executing the same process as the information adjustment process described above. In other words, the adjustment process converts the corrected three-dimensional object information D13 into the modeled object information D12 having information for determining the target shape of the result of the first step based on the content of the predetermined process executed in the second step. can be converted. Further, in the adjustment process, similar to the information adjustment process, the details of the process performed when converting the corrected three-dimensional object information D13 into the molded object information D12 are stored in the storage device 23 as adjustment information D16.

The selection process is a process of selecting the facility 5 to be used for manufacturing the three-dimensional object. In this embodiment, the selection process extracts and selects one or more first facilities 51 and one or more second facilities 52 from the list of facilities 5 available in the manufacturing system 1 in the facility information D15. More specifically, the selection process can execute one or more first processes by searching a list of facilities using the additive manufacturing technology (the first list of the facility information D15) based on the manufacturing process information D14. One or more specific first facilities 51 are extracted and selected. In the selection process, one or more second processes can be executed by searching a list of equipment using manufacturing technology other than additive manufacturing technology (second list of equipment information D15) based on manufacturing process information D14. One or more specific second facilities 52 are extracted and selected.

In this way, the selection process may include, for a manufacturing process, one or more specific first facilities 51 performing one or more first processes and one or more specific second facilities 51 performing one or more second processes. and select. The selection process may further refer to the adjustment information D16 to extract one or more specific first facilities 51 and one or more specific second facilities 52 . With this configuration, when a process that cannot be executed by the second facility 52 for executing a predetermined process in the second process is included due to a change in the shape imparted to the three-dimensional object shape by the information adjustment process, the selection process can be extracted and selected by excluding the certain second facility 52 . Alternatively, the arithmetic circuit 24 may first select the second equipment 52 for executing the predetermined process of the second step by the selection process, and then execute the information adjustment process. In this case, when the arithmetic circuit 24 determines that the selected second equipment 52 cannot execute the predetermined process due to the correction in the information adjustment process, it is necessary to reselect the second equipment 52 by executing the selection process again. .

In the selection process, if there is no second equipment that can execute the predetermined process of the second step based on the adjustment information D16 and the selection cannot be made, the selection of the equipment can be interrupted and an error can be output. The selection process may be configured, for example, to display on the input/output device 21 or the like that an error has occurred. By configuring in this way, the arithmetic circuit 24 selects the second equipment by the selection process while having the physically impossible process in the predetermined process executed in the second process, and starts manufacturing by the execution process. can prevent you from doing it.

In the information adjustment process described above, when the three-dimensional object shape to be manufactured is corrected, the arithmetic circuit 24 selects one or more specific first facilities 51 and one or more specific second facilities 52 in the selection process. , the corrected three-dimensional object information D13 is transmitted to the terminal device 6. FIG. In this way, the arithmetic circuit 24 can request approval from the client for manufacturing based on the corrected shape in a state where the equipment for executing the manufacturing process has been determined. As a result, it is possible to prevent the occurrence of a situation in which the equipment for executing the manufacturing process cannot be selected after approval by the client, and the product cannot be manufactured.

The execution process is a process for executing the manufacturing of the three-dimensional object. More specifically, the execution process is for manufacturing a three-dimensional object according to the manufacturing process information D14 using one or more specific first facilities 51 and one or more specific second facilities 52 selected in the selection process. Output instructions. For example, in the execution process, the stereoscopic It provides information necessary for manufacturing things. In the management system 4 of the facility 3 having the specific first equipment 51, as information necessary for manufacturing the three-dimensional object, information on the contents of the first process, destination of the result of the first process (specific second equipment 52 locations) are given. In the management system 4 of the facility 3 with the specific second equipment 52, as information necessary for manufacturing the three-dimensional object, information on the contents of the second process, the destination of the result of the second process (for example, the requester specified delivery address) information is included. In this embodiment, the manufacturing execution system 2 is communicably connected to the management system 4 through the communication network 71 by the communication circuit 22 . In this way, in the execution process, necessary information is provided to the management system 4 through the communication network 71 to cause the three-dimensional object to be manufactured.

In the present embodiment, the arithmetic circuit 24, for example, when executing the correction process, starts the execution process when the requester approves the production of the three-dimensional object in response to the presentation of the corrected three-dimensional object information D13. can be configured as The arithmetic circuit 24 may also be configured to initiate the execution process without requiring approval from the client if the correction process is not being executed.

In this manner, the manufacturing execution system 2 can manufacture a three-dimensional object based on the three-dimensional object information D11 acquired from the terminal device 6 using the information processing system 2A and the execution system 2B. In addition, as described above, the manufacturing execution system 2 can adjust the target shape of the result of the first process based on the predetermined processing in the second process of the manufacturing process. Furthermore, when the three-dimensional object shape is not suitable for manufacturing by the equipment of the first process, the manufacturing execution system 2 can correct the shape to a shape suitable for manufacturing, and then adjust the target shape of the result of the first process.

The information adjustment processing executed by the arithmetic circuit 24 will be described more specifically. As described above, the information adjustment process corrects the shape of the three-dimensional object so as to compensate for the shape change that occurs in the predetermined process of the second process with respect to the resulting object (modeled object) formed in the first process. Thus, the target shape of the model can be determined. More specifically, the modeled object may be reduced or increased in dimension, or deformed, as examples of shape change in the second step.

Therefore, for example, the target shape of the modeled object can be determined so as to correspond to the shape of the three-dimensional object by reducing the dimensions by a predetermined process in the second step included in the manufacturing process. Also, the target shape of the modeled object can be determined so as to correspond to the shape of the three-dimensional object by increasing the dimensions by a predetermined process in the second step included in the manufacturing process. Also, the target shape of the modeled object can be determined so as to correspond to the shape of the three-dimensional object by deforming the shape by predetermined processing in the second step included in the manufacturing process. The deformation of the shape includes, for example, deformation due to stress applied to the modeled object in a predetermined process, or deformation due to heat treatment of the modeled object in a predetermined process.

As an example of shape modification that compensates for the dimensional reduction due to the predetermined treatment in the second step, a case where a ring is manufactured by a manufacturing technique including an additive manufacturing technique will be described. A ring can be made by casting, for example, using the so-called lost wax method. The lost wax method is one of the methods for casting rings. In the lost-wax method, when a ring is produced using additive manufacturing technology, a prototype of the ring is formed using wax, which is a material that melts when heat is applied, using additive manufacturing technology. Then, by solidifying the periphery of the prototype with gypsum, a mold to be used for casting is produced. When the ring-shaped wax is melted and removed from the mold, a cavity having the same shape as the original wax-shaped ring is formed inside the mold. A metal ring is cast by pouring a molten metal material (for example, gold, silver, platinum, etc.) into the cavity and cooling and solidifying it.

A ring thus cast using the lost wax method may be polished to smooth the surface of the ring. Therefore, in the second step, the ring cast based on the prototype of the ring formed in the first step using manufacturing technology including additive manufacturing technology is polished. When the ring is polished in this manner, the polished portion is shaved, and the ring becomes smaller than the shape of the prototype modeled with wax. That is, the dimensions are reduced by the polishing process performed as one of the predetermined processes in the second step.

Thus, where the second step includes a polishing process, the cast ring is reduced in size by a second step after the casting step. Therefore, the information adjustment process determines the target shape of the prototype of the ring to be shaped so that the size of the target shape is reduced to achieve the desired ring shape. That is, the dimensions of the target shape of the original ring to be formed in the first step are increased with respect to the dimensions of the shape of the ring to be produced because the shape to be the cutting allowance is added. As described above, the information adjustment process can convert the three-dimensional object information D11 into the modeled object information D12 having the determined target shape information.

In the execution process, when the target shape indicated by the information in the object information D12 is formed by the first equipment that executes the first step, a prototype of a ring having dimensions larger than the three-dimensional object shape indicated by the information in the three-dimensional object information D11 is formed. be done. Then, in the execution process, one or more second facilities 52 that execute the second step cast a metal ring by the lost-wax method using the prototype of the ring. Since the cast ring has the same shape as the original form of the ring, the execution process is to polish the ring by one or more second equipments 52 that are the same as or different from the above, so that the ring is three-dimensional. A ring having a shape indicated by the information included in the object information D11 can be produced.

In this way, the arithmetic circuit 24 converts the three-dimensional object information D11 having the information indicating the shape of the three-dimensional object to be produced according to the predetermined process (for example, polishing process) executed in the second step through the information adjustment process. It can be converted into the modeled object information D12 having information indicating the target shape in which the dimension that is reduced by the predetermined processing is compensated. As a result, the manufacturing execution system 2 can manufacture a three-dimensional object whose shape after all the steps of the first and second steps are completed is equivalent to the shape of the three-dimensional object indicated by the information contained in the three-dimensional object information D11. can.

Next, an example of shape modification that compensates for an increase in dimension due to the predetermined treatment in the second step will be described using a manufacturing technique including an additive manufacturing technique that is different from the example of casting a ring. do. The ring may be shaped using a manufacturing technique that utilizes additive manufacturing techniques to form an underlying shape in a resin material. The ring shaped in this way can be provided with a metal-like texture by performing a coating process such as metal plating in the second step. The ring may be larger than the modeled shape because the coating is applied to the modeled shape. That is, the coating process increases the dimensions.

Further, for example, when a ring has a pattern having fine uneven shapes, the dimensions of the uneven parts are similarly increased by the coating treatment, and the uneven shape may differ from the original pattern.

In this way, when the second step includes the coating process, the ring shaped in the first process is increased in dimension by the coating process, which is one of the predetermined processes performed in the second process, and becomes a three-dimensional object. The shape can be changed. Therefore, the information adjustment process determines the target shape of the ring to be formed so that the desired ring shape is achieved by increasing the dimensions of the target shape. That is, the dimensions of the target shape of the ring to be formed in the first step are smaller than the dimensions of the shape of the ring to be manufactured because the shape corresponding to the coating film thickness is removed. As described above, the information adjustment processing can be converted into the modeled object information D12 having the target shape information for which the three-dimensional object shape has been determined.

When the execution process forms the target shape indicated by the information included in the object information D12 by the first equipment that executes the first step, a ring smaller in size than the three-dimensional object information D11 is produced using a resin material. Then, in the execution process, the one or more second equipments 52 that execute the second step apply a coating process to the ring, thereby manufacturing the ring having the shape indicated by the information included in the three-dimensional object information D11. can.

In this way, the arithmetic circuit 24 converts the three-dimensional object information D11 having information indicating the shape of the three-dimensional object to be produced according to the predetermined process (for example, the coating process) executed in the second step through the information adjustment process. It can be converted into the modeled object information D12 having information indicating the target shape in which the increased dimension is compensated for by the predetermined processing. As a result, the manufacturing execution system 2 can manufacture the shape of the resulting product after all the steps of the first step and the second step are equivalent to the shape of the three-dimensional object.

Compensation for a decrease in dimension and compensation for an increase in dimension caused by a predetermined process by the information adjustment process described above may be performed on the same three-dimensional object information D11. For example, when a modeled object is modeled by laminating resin materials, there is a possibility that the layers of the laminated material will appear like patterns on the surface of the modeled object. Therefore, when forming a base modeled object (for example, a ring) with a resin material and coating the modeled object, in order to remove such a layer shape, the modeled object must be coated before the coating process. Processing that involves cutting such as polishing can be performed. Thus, if the second step includes a size-decreasing process and a size-increasing process, the information adjustment process can perform shape modifications to compensate for shape changes caused by both processes.

The modification by the information adjustment process to compensate for the shape change caused by the predetermined process in the second step may limit the processing method of the second equipment that performs the predetermined process in the second step. For example, in a modeled object, a portion that cannot be accessed by a cutting tool (for example, a drill for cutting) cannot be polished by alternating cutting, so it is necessary to modify such a portion to provide the above-mentioned shaving allowance. Even if it does, the cutting process cannot be performed with the cutting tool in the second step. Therefore, when performing correction such as providing a cutting allowance for such a portion, the arithmetic circuit 24 uses a cutting tool other than the inaccessible cutting tool in the selection process (for example, the operator uses a file to A second facility 52 capable of performing the cutting process (such as by grinding by hand) should be selected as the facility for performing the predetermined treatment in the second step.

Next, a case where heat treatment is performed in the second step will be described as an example of shape correction that compensates for shape deformation due to the predetermined processing in the second step. In the first step, for example, when modeling using a metal material, the manufacturing process may include a treatment similar to heat treatment in the second step. Heat treatment-like treatments include, for example, treatments involving temperature changes, phase changes or crystallization. Treatments involving temperature changes include, for example, heat imparting treatments such as sintering and annealing. A product subjected to the above-described treatment may be deformed due to heat or the like.

In the information adjustment process, in the predetermined process in the second process, the three-dimensional object shape is adjusted so as to compensate for the deformation of the shape due to the application of such heat or the like to the modeled object modeled in the first process. can be fixed. Therefore, the information adjustment process can determine the target shape of the modeled object by correcting the shape of the three-dimensional object so as to compensate for the deformation of the shape caused by heat treatment or the like. Thereby, the information adjustment processing can convert the three-dimensional object information D11 into the modeled object information D12 having information indicating the target shape. As described above, the deformation of the shape is not limited to the application of heat or the like. For example, a process that applies stress to the modeled object in the predetermined process of the second step is executed. can also occur. In this way, the information adjusting process can determine the target shape by correcting the shape of the three-dimensional object so as to compensate for the deformation when the shape is deformed in any predetermined process in the second step.

Next, correcting the three-dimensional object shape so as to give a fixed shape for fixing the modeled object in the predetermined process in the second step will be described. When performing the predetermined process in the second step on the modeled object that has been formed by the first equipment that performs the first step, it may be preferable to perform the predetermined process while fixing the modeled object. In order to efficiently execute the predetermined processing in the second step, the arithmetic circuit 24 can give the three-dimensional object shape a fixed shape that can be used in the predetermined processing in the second step in the information adjustment processing.

Examples of the fixed shape include holes for bolting and legs for fixing. For example, when cutting a modeled object formed using a metal material, it is necessary to fix the modeled object with a large gripping force during the cutting. In such a case, by providing a bolt fastening hole in the modeled object, the hole and the bolt can be tightened to securely fix the modeled object. Thereby, the predetermined treatment in the second step can be easily performed in the second facility.

A fixed shape may become an unnecessary shape when a three-dimensional object is produced. Therefore, the fixed shape can be given to metal parts that require cutting and that need to be fixed and for which there is no problem in leaving the fixed shape in the final shape. Alternatively, the fixed shape can be imparted to those for which there is a method that allows the fixed shape to be removed after cutting within the requirements for the manufacture of three-dimensional objects.

Next, in a predetermined process in the second step, in order to fix the modeled object modeled in the first step, the modeled object and an auxiliary tool separate from the modeled object are formed in the first step. , determining the target shape of the result of the first step. It may be preferable that the modeled object modeled in the first step is fixed using an auxiliary tool in the predetermined processing executed in the subsequent steps. Auxiliary tools are, for example, fixtures and jigs that can be attached to the equipment that executes the second step, and can be used to fix the modeled object or to guide the modeled object when it is moved. . Since the modeled object may have various shapes, it may be necessary to design and manufacture an auxiliary tool for the modeled object according to the various shapes. In the information adjustment processing, based on the three-dimensional object shape of the three-dimensional object indicated by the information included in the three-dimensional object information D11, the assisting tool is automatically generated, and the information including the shape of the three-dimensional object and the shape of the assisting tool is displayed. Object information D12 can be generated. Incidentally, such an auxiliary tool is generally a part used when executing a predetermined step in the second step, for example, and is not a part sent to the client.

As described above, the information adjustment process executed by the arithmetic circuit 24 determines the target shape of the result of the first process based on the three-dimensional object information D11 based on the content of the predetermined process executed in the second process. It can be converted into the modeled object information D12 having information for.

Different from manufacturing in which parts of the same shape are mass-produced, various modifications (customization) can be made to the three-dimensional object that is formed in manufacturing using the first process using additive manufacturing technology. Three-dimensional objects having such various shapes are modeled in the first step so as to compensate for the shape deformation caused by the predetermined step executed in the second step by the operator. Designing the target shape of the resulting product is difficult even for an operator with skill. In addition, for such three-dimensional objects having various shapes, the operator can decide whether to attach or remove the fixed shape by considering a wide variety of available devices, and select the object to be formed in the first step. May require skilled ability to generate. Similarly, for a three-dimensional object having such various shapes, a skilled ability may be required for a worker to generate an auxiliary tool according to the three-dimensional object. Therefore, many skilled workers may be required to manufacture a large number of three-dimensional objects. However, as described above, according to the manufacturing execution system 2 according to the present embodiment, based on the three-dimensional object shape indicated by the three-dimensional object information D11, the arithmetic circuit 24 performs It is configured to determine a target shape in which the three-dimensional object shape is corrected so as to compensate for the deformation in consideration of the deformation of the shape due to the predetermined processing. Further, according to the manufacturing execution system 2 according to the present embodiment, the arithmetic circuit 24 is configured to give a fixed shape based on the three-dimensional object shape indicated by the information included in the three-dimensional object information D11. there is Further, according to the manufacturing execution system 2 according to the present embodiment, the arithmetic circuit 24 is configured to generate the assisting tool based on the three-dimensional shape of the three-dimensional object indicated by the information included in the three-dimensional object information D11. there is Therefore, the arithmetic circuit 24 of the manufacturing execution system 2 can automatically adjust the shapes of many three-dimensional objects. In addition, even if there are not many skilled workers, it is possible to manufacture many three-dimensional objects.

As described above, FIG. 5 is a flow chart showing an example of the operation of the manufacturing system 1 according to this embodiment. This example shows the operation when executing the information adjustment process in the information processing system 2A. The operation of the manufacturing system 1 will be described with reference to FIG.

In the manufacturing system 1, the client uses the terminal device 6 when requesting the manufacture of a three-dimensional object. In the terminal device 6, the arithmetic circuit 64 executes acquisition processing (S10) to acquire the three-dimensional object information D11. When acquiring the three-dimensional object information D11, the arithmetic circuit 64 stores the three-dimensional object information D11 in the storage device 63. FIG. This allows the client to input the three-dimensional object information D11 according to the instructions on the screen. The arithmetic circuit 64 executes transmission processing ( S<b>20 ), and transmits the three-dimensional object information D<b>11 acquired in the acquisition processing to the manufacturing execution system 2 via the communication circuit 62 .

In the manufacturing execution system 2, when the arithmetic circuit 24 receives the three-dimensional object information D11 transmitted by the transmission process via the communication circuit 22, it executes a storage process (S30), and stores the three-dimensional object information D11 in the storage device 23. Store. Arithmetic circuit 24 executes determination processing ( S<b>40 ), determines a manufacturing process for manufacturing a three-dimensional object based on three-dimensional object information D<b>11 , generates manufacturing process information D<b>14 , and stores it in storage device 23 . The arithmetic circuit 24 executes information adjustment processing (S50), refers to the manufacturing process information D14, and converts the three-dimensional object information D11 into one or more first processes based on predetermined processes executed in one or more second processes. It is converted into modeled object information D12 having information for determining the target shape of the result of the process. In the information adjustment process, the arithmetic circuit 24 also generates adjustment information D16 relating to the process performed when converting the three-dimensional object information D11 into the modeled object information D12, and stores it in the storage device 23 .

Arithmetic circuit 24 executes a selection process (S60) and selects equipment 5 to be used for manufacturing a three-dimensional object. More specifically, in the selection process, the arithmetic circuit 24 refers to the manufacturing process information D14 and the adjustment information D16 to select one or more specific specific Select the first facility 51 . Similarly, the arithmetic circuit 24 selects one or more specific second facilities 52 to be used for one or more second processes from one or more second facilities 52 . In the selection process, if one or more specific second facilities to be used in one or more second processes cannot be selected (S60: No), the arithmetic circuit 24 outputs an error and stores information about the error in the storage device. is displayed on the input/output device 21, and the operation of the manufacturing system 1 is terminated. If one or more specific second facilities can be selected (S60: Yes), the arithmetic circuit 24 executes the execution process (S70). Thereby, the arithmetic circuit 24 outputs an instruction for manufacturing a three-dimensional object according to the manufacturing process information D14 using the one or more specific first facilities 51 and the one or more specific second facilities 52 selected in the selection process. to the required management system 4. As a result, the manufacturing system 1 manufactures a three-dimensional object and delivers it to the destination specified by the client.

As described above, the three-dimensional object shape indicated by the information included in the three-dimensional object information D11 may not be suitable for manufacturing by equipment in the first step. As described above, the manufacturing system 1 according to the present embodiment can convert such three-dimensional object information D11 into modeled object information D12 having a shape suitable for manufacturing in the first step. can be done. The determination processing, correction processing, and adjustment processing included in the information adjustment processing for executing the above-described processing will be described in detail below.

The determination process determines whether or not the three-dimensional object shape indicated by the information included in the three-dimensional object information D11 is suitable for manufacturing by the equipment of the first step determined in the determination process. For example, the determination process may determine whether or not the three-dimensional object shape is suitable for manufacturing by determining whether or not the three-dimensional object shape can be modeled by the equipment of the first step. As an example of the determination, the determination process may determine whether or not the three-dimensional shape can be modeled without using support materials. This example will be described with respect to the case of producing a three-dimensional object 80A in the shape of the letter "I" as shown in FIG. 6A.

6A is a cross-sectional view of an example of the three-dimensional object shape of the three-dimensional object 80A indicated by the information included in the three-dimensional object information D11 input from the terminal device 6. FIG. The three-dimensional object 80A has a shape having a bottom surface 81, a top surface 82, and a vertical member 83 connecting the member having the bottom surface 81 and the member having the top surface . When the first facility 51 that models the three-dimensional object 80A models the three-dimensional object 80A by layering the three-dimensional object 80A from the bottom surface 81 toward the top surface 82, the first facility 51 uses , it is necessary to provide a support material under the upper surface 82 for supporting the relevant portion. Therefore, when forming a three-dimensional object without changing the stacking direction and without using support materials, the arithmetic circuit 24 needs to correct the shape of the three-dimensional object information D11. Therefore, the determination process determines that the three-dimensional object shape is not suitable for manufacturing by the equipment of the first step.

In the judgment process, if it is judged that it is not suitable for manufacturing by the equipment of the first process, the arithmetic circuit 24 executes the correction process. The correction process corrects the shape of the three-dimensional object to a shape suitable for manufacturing using equipment in the first step. FIG. 6B is a cross-sectional view of a shape obtained by correcting the solid object shape having the cross section shown in FIG. 6A by correction processing. As shown in FIG. 6B, in the three-dimensional object 80B, the shape of the vertical member 83 of the three-dimensional object 80A is corrected to the vertical member 84. As shown in FIG. The vertical member 84 is manufactured so that its width increases from the lower side (that is, the bottom surface 81 side) toward the upper side (that is, the upper surface 82 side). In this way, by providing a structure for supporting from below, the part having the upper surface 82 can be modeled without providing a support material.

Such correction can be performed when there is no problem even if the shape of the three-dimensional object is corrected. In the case of the three-dimensional object 80A having the cross section shown in FIG. 6A, if there is no problem in changing the shape of the vertical member 83, the three-dimensional object shape can be corrected to the three-dimensional object shape of the three-dimensional object 80B having the cross section shown in FIG. 6B. can. Determination of whether or not correction is possible may be performed, for example, by referring to the non-correctable area information or correctable area information provided in the three-dimensional object information D11, as described above. . In the three-dimensional object 80A shown in FIG. 6A, if the three-dimensional object information D11 includes correction impossible area information in which the bottom surface 81 and the top surface 82 are set as portions whose shape cannot be changed, the correction as described above can be performed.

The determination of whether or not the three-dimensional object shape indicated by the information contained in the three-dimensional object information can be manufactured by the equipment of the first step by the determination process is limited to whether or not the three-dimensional object shape can be manufactured without using the supporting material as described above. Absent. For example, the determination process determines whether or not the three-dimensional object shape indicated by the information included in the three-dimensional object information D11 can be manufactured by the equipment of the first process according to the determined manufacturing process and the material set as the molding material. You can judge.

If the equipment for the first process that has been determined cannot be molded with the material according to the three-dimensional object shape indicated by the three-dimensional object information (i.e., the first process that is determined in the manufacturing process that can is not present), the arithmetic circuit 24 determines that correction is necessary. Then, the arithmetic circuit 24 corrects the shape of the part that cannot be modeled according to the shape of the three-dimensional object by correction processing. For example, if the dimensions of the three-dimensional object shape are too fine to manufacture with the determined type of first process and the set modeling material, the arithmetic circuit 24 corrects the three-dimensional object shape as described above through correction processing. It can be corrected to a manufacturable shape. When correcting the shape in this way, if the three-dimensional object information D11 includes non-correctable region information, as described above, the arithmetic circuit 24 is configured so as not to change the shape of the previously set non-changeable region. Next, the three-dimensional object shape is corrected.

The determination process determines whether or not the shape of the three-dimensional object is a shape that is efficient for modeling with the equipment of the first process, and whether it is suitable for manufacturing with the equipment of the first process determined in the determination process. It may be determined whether The arithmetic circuit 24 confirms, for example, that by changing the stacking direction of the three-dimensional object shape, the manufacturing time is shortened, the amount of support material used is reduced, etc., and the shape that is efficient for modeling is determined. It may be determined whether

After the correction process, or after determining that correction is unnecessary in the determination process, the arithmetic circuit 24 executes the adjustment process. The adjustment process determines the target shape of the result of the first step based on the three-dimensional object shape indicated by the three-dimensional object information or the shape obtained by correcting the three-dimensional object shape by the correction process. As a result, the adjustment process can create the modeled object information D12 based on the three-dimensional object information D11 or the corrected three-dimensional object information D13. The adjustment process executes the same process as the information adjustment process described above. As described above, in the adjustment processing, the processing performed on the shape indicated by the information included in the three-dimensional object information D11 or the corrected three-dimensional object information D13 is stored in the storage device 23 as the adjustment information D16.

As described above, the information processing system 2A of the manufacturing system 1 converts the three-dimensional object information D11 input from the terminal device 6 into the three-dimensional object information D12 having information for determining the target shape of the result of the first process. can be converted to As described above, the information processing system 2A can reproduce the three-dimensional object even if the three-dimensional object shape indicated by the information included in the three-dimensional object information D11 is not suitable for manufacturing by the equipment in the first step. The target shape can be determined based on the shape obtained by correcting the shape to a shape suitable for manufacturing by the equipment of the first step. Therefore, even if the three-dimensional object information D11 has information indicating a three-dimensional object shape that is not suitable for manufacturing by the equipment in the first step, it can be converted into appropriate modeled object information D12.
