The auxiliary step may be a step for targeting the modeled object obtained in the addition step. The auxiliary step may be performed after at least one additional step. When the manufacturing process includes a plurality of addition steps, the auxiliary step may be executed between the plurality of addition steps. The auxiliary step may be a step of further processing the three-dimensional object formed halfway in the addition step to make a finished product. The auxiliary step may be a step of subjecting a three-dimensional object formed to the end in the addition step to a surface treatment or a heat treatment to make a finished product.

The storage device 23 includes one or more storages (non-temporary storage media). The storage may be, for example, a hard disk drive, an optical drive, or a solid state drive (SSD). Further, the storage may be any of an internal type, an external type, and a NAS (network-attached storage) type. The manufacturing execution system 2 may include a plurality of storage devices 23. Information may be distributed and stored in the plurality of storage devices 23.

The information stored in the storage device 23 includes three-dimensional object information D11, manufacturing process information D12, request level information D13, worker database (worker DB) D14, equipment information D15, and usage schedule information D16. include.

It suffices if it is stored in the storage device 23 when it is needed by 24.

The three-dimensional object information D11 is information including information (shape information) for determining the shape of the three-dimensional object. The three-dimensional object information D11 is given by, for example, a client who requests the production of a three-dimensional object. Examples of the shape information include information for directly specifying the shape of the three-dimensional object and information for indirectly specifying the shape of the three-dimensional object. Examples of information that directly specifies the shape of a three-dimensional object include 3D data (for example, 3D CAD data and 3DCG data) expressing the shape of the three-dimensional object. As an example of the information for indirectly specifying the shape of the three-dimensional object, there is information including the required value of the characteristic of the shape of the three-dimensional object. A characteristic is a property or performance realized by a three-dimensional object depending on its shape. If the three-dimensional object is part of the body of a vehicle or aircraft, its characteristics include strength, air resistance, and lift. Given the required value of the characteristics of the shape of the three-dimensional object, it is possible to design the shape of the three-dimensional object that satisfies the required value (it is possible to narrow down the design space and derive a design solution), so the shape of the three-dimensional object is determined. can do. The three-dimensional object information D11 includes, if necessary, information for specifying an attribute other than the shape of the three-dimensional object, in addition to the shape information. Attributes other than the shape of the three-dimensional object may include size, color, material, and the like. The three-dimensional object information D11 may include priority information indicating priority items to be prioritized in determining the manufacturing process. Examples of priority items are short delivery time, quality, information about the material of the three-dimensional object (material itself or material characteristics, etc.), surface treatment of the three-dimensional object (painting, coating, etc.), high probability of success, manufacturing cost. Can be mentioned.

The manufacturing process information D12 is information indicating a manufacturing process of a three-dimensional object. As described above, the manufacturing process includes at least one additional step that utilizes the additive manufacturing technique and one or more auxiliary steps that utilize a manufacturing technique that is different from the additive manufacturing technique. The manufacturing process is determined based on the three-dimensional object information D11. In the present embodiment, the arithmetic circuit 24 determines the manufacturing process from the three-dimensional object information D11 by the determination process described later, and generates the manufacturing process information D12. The manufacturing process includes, if necessary, a quality confirmation process. The quality confirmation process is a process for confirming quality. Examples of the quality confirmation step include a quality confirmation step (first quality confirmation step) executed after the addition process and a quality confirmation step (second quality confirmation step) executed after the auxiliary step. In the first quality confirmation step, for example, the shape of the modeled object obtained by the addition step is confirmed. In the second quality confirmation process, for example, the processing, processing, and assembly results in the auxiliary process are confirmed. The manufacturing process includes, if necessary, a transportation process. This is a process for transporting a three-dimensional object. The transportation step may be a step of transporting a part or all of a three-dimensional object (or a modeled object in the process of manufacturing the three-dimensional object). The process of transporting a part of the three-dimensional object is a step of transporting one of the plurality of parts of the three-dimensional object when the three-dimensional object is composed of a plurality of parts. Examples of transportation include transportation between equipment 5 and transportation from equipment 5 to a destination of a three-dimensional object. The transportation between the equipment 5 includes the transportation between the first equipment 51 and the second equipment 52, the transportation between the first equipment 51, and the transportation between the second equipment 52.

The requirement level information D13 defines the conditions necessary to meet the requirements for a three-dimensional object manufactured using the additive manufacturing technique. The request level information D13 is given by, for example, a requester who requests the production of a three-dimensional object. That is, the requester can input the request level information D13 together with the three-dimensional object information D11. The required level information D13 is associated with the three-dimensional object information D11, and is also associated with the manufacturing process information D12 determined based on the three-dimensional object information D11.

Requirements for three-dimensional objects manufactured using additive manufacturing technology include security requirements for three-dimensional objects and proficiency requirements for the execution of manufacturing processes. Security for a three-dimensional object relates, for example, to the protection of personal information about the three-dimensional object and the protection of confidential information about the three-dimensional object. As described above, the three-dimensional object may be personalized to the target person, in which case the three-dimensional object has a predetermined shape that matches the shape of the target person's body. Therefore, it is desirable that the shape of a three-dimensional object having a predetermined shape that matches the shape of the target person's body is kept secret from the viewpoint of protecting personal information. In addition, the three-dimensional object may be used, for example, as a part of a manufacturing device of a company's own factory. In this case, the three-dimensional object may be designed based on confidential information that the company wants to manage as know-how. .. Therefore, the requirement level information D13 may include a requirement value of one or more security levels regarding a three-dimensional object. The type of security level included in the request level information D13 may be set by the requester who requests the manufacture of the three-dimensional object. The security level may not be a single index but may be a different index for each requester. This is because what kind of security is required differs depending on the requester. For example, the requester may set a required value for a required security level among a plurality of security levels prepared in advance.

The security level for a three-dimensional object may include a personal information security level and a confidential information security level.

The required value of the personal information security level is set based on the degree of personal information contained in the shape of the three-dimensional object. The larger the degree of personal information, the larger the required value of the security level is set, and the smaller the degree of personal information, the smaller the required value of the security level is set. The degree of personal information is the degree to which a predetermined shape of a three-dimensional object represents the shape of the target person's body. The higher the possibility that the target person can be identified from the predetermined shape of the three-dimensional object, the greater the degree to which the predetermined shape of the three-dimensional object represents the shape of the body of the target person is set. For example, when the predetermined shape of the three-dimensional object represents the shape of the head of the target person, the predetermined shape of the three-dimensional object represents the target person rather than the case where the predetermined shape of the three-dimensional object represents the shape of the hand of the target person. The degree to which the shape of the body is represented can be set to a large extent. That is, if the shape of the target person's body is well represented on the three-dimensional object, the required value of the security level is set large.

The required value of the confidential information security level is set based on the degree of confidential information regarding the three-dimensional object. For example, when a three-dimensional object is deeply involved in the know-how of a company, the required value of the confidential information security level is set high. For example, if there is a high possibility that the contents of a project (new entry into a new market, etc.) that a company carries out in secret can be grasped from a three-dimensional object, the required value of the confidential information security level is set high.

Proficiency in performing a manufacturing process is related, for example, to at least one of the accuracy of the shape of the three-dimensional object and the speed of manufacturing the three-dimensional object. It is considered that a worker with a higher skill level can manufacture a three-dimensional object with higher shape accuracy and can manufacture a three-dimensional object faster. Therefore, the requirement level information D13 may include skill level requirements for one or more items relating to the execution of the manufacturing process.

As mentioned above, the manufacturing process includes additional steps that utilize additive manufacturing techniques. Corresponding additional manufacturing equipment is used for the additional process. One or more items related to the execution of the manufacturing process are the proficiency in the operation of the additional manufacturing equipment, the proficiency in the pretreatment of the additional manufacturing equipment, the proficiency in the post-treatment of the additional manufacturing equipment, the proficiency in the removal treatment of the support material, and the proficiency in the removal treatment of the support material. , At least one of the proficiency levels of quality inspection of the deliverables of the additive manufacturing process may be included. Examples of proficiency in the operation of additional manufacturing equipment include the speed, accuracy and stability of the operation of the additional manufacturing equipment, the license or grade for the operation of the additional manufacturing equipment, and the qualifications for the operation of the additional manufacturing equipment. Presence / absence or grade can be mentioned. Examples of proficiency in pretreatment of additional manufacturing equipment include the speed, accuracy and stability of the additional manufacturing equipment setup, as well as the quality stability resulting from the additional manufacturing equipment setup. The setup of additional manufacturing equipment may include, for example, preparation of 3D data, preparation of material cartridges and preparation of shaped plates. Examples of post-treatment proficiency in additional manufacturing equipment include the speed, accuracy and stability of removal of three-dimensional objects from additional manufacturing equipment, and the stability of quality resulting from the removal of three-dimensional objects from additional manufacturing equipment. In addition, the accuracy of maintenance after use of the additional manufacturing equipment can be mentioned. Examples of proficiency in the process of removing the support material include speed, accuracy and stability of removal of the support material. The accuracy of removing the support material may be evaluated by whether the support material can be removed cleanly. The stability of removal of the support material may be evaluated by the probability of forgetting to remove the support material. Examples of proficiency in quality inspection of three-dimensional objects after the addition manufacturing process include speed, accuracy and stability of visual inspection. The accuracy of the visual inspection is, for example, the low probability of overlooking a defect in a three-dimensional object.

The manufacturing process includes an auxiliary process that utilizes a manufacturing technique different from the additive manufacturing technique. Corresponding auxiliary manufacturing equipment is used for the auxiliary process. One or more items related to the execution of the manufacturing process are the skill level of the operation of the auxiliary manufacturing equipment, the skill level of the pretreatment of the auxiliary manufacturing equipment, the skill level of the post-treatment of the auxiliary manufacturing equipment, and the quality of the three-dimensional object after the auxiliary manufacturing process. The skill level of the inspection may be included. Examples of proficiency in the operation of auxiliary manufacturing equipment include the speed of operation of auxiliary manufacturing equipment, the accuracy of operation of auxiliary manufacturing equipment, the existence or grade of license for the operation of auxiliary manufacturing equipment, and the operation of auxiliary manufacturing equipment. Whether or not there is a qualification or grade regarding.

One or more items relating to the execution of the manufacturing process may be set for each process included in the manufacturing process. For example, when the manufacturing process includes a plurality of addition steps, one or more items related to the execution of the manufacturing process are set for each addition step.

By preparing a plurality of proficiency points related to the execution of the manufacturing process, it is possible to execute filtering of workers based on various proficiency points. Therefore, it is possible to select an appropriate worker by manufacturing a three-dimensional object.

The worker database D14 is a database relating to workers who execute the manufacturing process of a three-dimensional object. The worker database D14 contains level information of a plurality of workers. The level information is used for selecting a worker in charge of manufacturing a three-dimensional object in the selection process D30 described later executed by the arithmetic circuit 24. The level information includes a security rating for the corresponding worker and a proficiency rating for performing the manufacturing process. The evaluation value regarding security includes the upper limit of the security level (personal information security level and confidential information security level) that can be handled by the worker. The evaluation value regarding the skill level regarding the execution of the manufacturing process includes the value of the skill level regarding one or more items regarding the execution of the manufacturing process of the worker. One or more items are, for example, the skill level of the operation of the additional manufacturing equipment, the skill level of the pretreatment of the additional manufacturing equipment, the skill level of the post-treatment of the additional manufacturing equipment, the skill level of the removal treatment of the support material, and the auxiliary manufacturing. Includes equipment operation proficiency. The skill level of the operation of the additional manufacturing equipment, the skill level of the pretreatment of the additional manufacturing equipment, the skill level of the post-treatment of the additional manufacturing equipment, and the skill level of the removal treatment of the support material may be set for each additional manufacturing facility. This is because it is thought that these proficiency levels will change if the additional manufacturing equipment is different. The skill level of the operation of the auxiliary manufacturing equipment may be set for each auxiliary manufacturing equipment. This is because it is thought that these proficiency levels will change if the auxiliary manufacturing equipment is different. Table 1 below shows an example of the worker database D14.

In Table 1, "SCL" means a security level. "Individual" means the personal information security level, and "confidential" means the confidential information security level. In Table 1, "SKL" means skill level. In Table 1, the security level and skill level are evaluated on a 5-point scale, and the higher the evaluation, the larger the numerical value. Further, "0" in Table 1 indicates that the corresponding equipment cannot be handled.

Equipment information D15 is a list of equipment 5 available in manufacturing system 1.

(Geographical location of Facility 3), including. The process that can be executed in the additional manufacturing equipment is, for example, a process that uses a modeling method by additive manufacturing technology. There are various materials that can be used in the additional manufacturing equipment, such as synthetic resin and metal, and the materials that can be used may be limited depending on the modeling method. The second list contains attribute information for each auxiliary manufacturing facility. The attribute information includes, for example, a process that can be performed in the auxiliary manufacturing facility and the location of the auxiliary manufacturing facility (eg, the geographical location of facility 3 with the auxiliary manufacturing facility).

For example, from the equipment 5 available in the manufacturing system 1, the first equipment 51 capable of executing the additional process and the second equipment 52 capable of executing the auxiliary process are selected. The usage schedule information D16 indicates a usage schedule of the first equipment 51 capable of executing the additional process and a usage schedule of the second equipment 52 capable of executing the auxiliary process. The schedule for using the equipment 5 can be determined based on an arbitrary unit time. As an example, the schedule for using the equipment 5 may be set on an hourly basis. The unit time is not limited to 1 hour, and may be 15 minutes, 30 minutes, 6 hours, 12 hours, 1 day, or the like. The usage schedule of the equipment 5 may be the usage schedule of the equipment 5 itself, but may be a combination of the usage schedule of the equipment 5 itself and the usage schedule of a person (worker) who can operate the equipment 5. For example, even if the equipment 5 itself is not used at a certain time zone, the equipment 5 may not be available unless there is a person who can operate the equipment 5.

For example, the three-dimensional object may be disassembled into a plurality of parts, and a part for assembling (uneven part or the like) may be added to each part. For example, the shape of the three-dimensional object may be a shape obtained by removing an unnecessary portion from the three-dimensional object or a shape having a necessary portion added. The unnecessary part or the necessary part may be determined based on the shape information, the attribute information, the priority information and the like included in the three-dimensional object information D11.
