The customer terminal 2 may include an input unit 21 and a display unit 22 for displaying an input screen for necessary information.

It is preferable that the three-dimensional model server 3 is provided with a database 31 that stores three-dimensional model data and the like and manages information, and functions as a cloud server in the communication network 4. The three-dimensional modeled object server 3 is not limited to the above, and may function as a local server on the business terminal (three-dimensional modeled object device) side.
Examples of the communication network 4 include the Internet.

The three-dimensional model creation system according to the present invention includes storage processing and order processing. Hereinafter, each of the storage process and the order process will be described in detail.

(1) Storage processing An example of storage processing will be described below with reference to FIG.

First, the mold data acquisition process is performed (S1). For example, when a customer provides a mold for manufacturing a three-dimensional object, the modeling unit 15 (three-dimensional modeling device) of the business terminal 1 acquires necessary data regarding the mold. An example of the mold data acquisition process will be described with reference to FIG.

First, the mold data is input (S11). Specifically, the mold data includes, for example, at least mold characteristic data. The mold characteristic data includes at least information on the material of the mold and information on the mechanical characteristics of the material of the mold. Information on mechanical properties preferably includes the coefficient of thermal expansion, the rate of contraction, and the amount of springback.

In the present embodiment, the mold data may be input by the business operator terminal 1, or the three-dimensional modeled object server 3 causes the customer terminal 2 to display an input screen, and the input unit 21 of the customer terminal 2 displays the input screen. You may be asked to enter it.
When the mold data is input, it may be transmitted to the business operator terminal 1 via the three-dimensional modeled object server 3.

In the present embodiment, when the material of the product is determined at the same time as the mold data is input, the material information of the product and the mechanical properties of the material can be acquired on the business terminal 1. It may be. In addition, the material may be selected according to the intended use of the product.

Next, the point cloud data is acquired by scanning the mold provided by the customer (S12). Here, an example of mold scanning will be described with reference to FIG. In the example of FIG. 4, the schematic measurement for measuring the rough shape of the mold surface and the detailed measurement for measuring the shape of the detailed portion of the mold surface are performed separately.

That is, by scanning the mold, the point cloud data A of the rough shape of the mold surface obtained by the schematic measurement and the point cloud data of the shape of the detailed part of the mold surface obtained by the detailed part measurement. B and is obtained.
In the present embodiment, as the portion measured as the point cloud data B, for example, a portion having a complicated shape, a portion having a continuously changing shape such as a curved surface, a fastening portion such as a screw portion, and dimensional accuracy. There are some strict parts.

The point cloud data C for generating the modeled object is generated by combining the point cloud data A and the point cloud data B.

As a combination method, it is sufficient that the usage ratio of the point cloud data A and the point cloud data B can be changed according to the shape of the product, the dimensional accuracy, and the like. For example, as shown in the illustrated example, the point cloud data B is used for the portion requiring a high degree of dimensional accuracy, and the point cloud data A is used otherwise. As a result, it is possible to generate a modeled object with higher dimensional accuracy.

Next, based on the mold data acquired in S11 and the point cloud data C generated by scanning in S12, three-dimensional model data for generating a three-dimensional model is generated (S13).

In the present embodiment, additional data can be added to the generated 3D model data. As shown in FIG. 2, when the customer has a two-dimensional drawing for generating a three-dimensional model in addition to the mold, the input / output unit 12 can also acquire the two-dimensional drawing data (S2). .. As the information of the two-dimensional drawing, the shape, dimensions and geometrical tolerances are preferable, and it is preferable to reflect the input information in the generated three-dimensional model data.

If the customer's mold cannot be acquired, the processing of S1 may not be performed, only the processing of S2 may be performed, and the three-dimensional model data may be generated from the two-dimensional drawing. In this case, it is preferable that the operator creates the three-dimensional CAD data based on the two-dimensional drawing, and the business operator terminal 1 generates the three-dimensional model data based on the three-dimensional CAD data.

In the present invention, the object to be modeled for generating three-dimensional model data is one that can manufacture a metal model, for example, a mold, a model sample, a design document, a painting that three-dimensionally depicts the model, or a model. It is preferable to include a picture of.

After the 3D model data is generated, the mold data acquisition process is completed, the process returns to the storage process of FIG. 2, and the 3D model data generation process is executed (S3).
The three-dimensional model data generation process will be described below with reference to FIG.

First, the three-dimensional model data of the generated mold data is acquired (S31).

Next, it is determined whether or not the acquired three-dimensional model data has a post-processing portion (S32). Whether or not there is a post-processed portion may be determined mechanically from the mold data, a two-dimensional drawing, or the like, or may be determined by visual inspection.

When it is determined that there is a post-processing location (YES in S32), the post-processing location data is generated, and at the same time, the correction data is acquired based on the post-processing location data (S33).
If it is determined by visual inspection that there is a post-processed part, post-processed part data is generated by input. At this time, the three-dimensional CAD data may be referred to, the three-dimensional model data, the mold data, or the like may be referred to, and the post-processing location data may be generated by the input of the operator.

The post-processing location data includes, for example, the post-processing location No. 1 in the region determined to be the post-processing location. Is assigned, and the post-processing part No. Corresponding to, it is generated by acquiring the coordinate position data (X coordinate, Y coordinate, Z coordinate), dimensional data, etc. of the 3D coordinates in the acquired 3D model data.
The post-processing location data preferably further includes information such as the content of post-processing, for example, whether to form a screw or a fitting portion (inlay). Here, the screw and the fitting portion are exemplary elements of a portion that needs to be matched with the mating part. Since these exemplary elements are locations that require processing according to the accuracy required by the customer, it is preferable to generate them as post-processing location data.

An example of the content of the post-processing location data will be described with reference to FIG. In the illustrated example, the post-processing location No. Reference numeral 1 denotes an example of data relating to post-machining of a screw hole. After this, the processed part No. 1 includes position coordinate data and dimensional data, as well as data on screw size and presence / absence of pilot hole processing. Therefore, based on the post-machining location data, additional machining of screw holes can be performed at a designated position during post-machining, which will be described later.

As shown in the figure, when there are a plurality of post-processing points based on the acquired 3D model data, the post-processing points No. (No. 1, No. 2, No. 3, ...) Can be allocated and necessary data can be acquired in association with the assigned data.

The correction data acquired based on the post-processing location data will be described in detail in the next step.

Next, the modified data corresponding to the generated post-processing location data is added to the acquired 3D model data, and the additional 3D model data is acquired (S34).
The addition of the correction data corresponding to the generated post-processing location data means, for example, the post-processing location No. 6 showing an example of the post-processing location data. Based on the coordinate position data and the dimensional data corresponding to 1, the data to be replaced with the shape data in the state before processing is added to the three-dimensional model data.
That is, the correction data is data for modifying the shape before post-processing, and is data for modifying the three-dimensional model data so that the post-processing portion is not formed in the post-processed shape.
By adding the correction data to the part of the 3D model data corresponding to the coordinate position data and the dimensional data of the post-processing part data, the part does not have a post-processed shape and is before the post-processing. It becomes a part that is shaped into a shape.
Therefore, in the additional 3D model data to which the correction data for the screw hole is added, the screw hole is post-processed, so that the screw hole is replaced with the data not formed at the time of 3D modeling.

In the present embodiment, the data is not limited to replacing the screw hole with non-modeled data, and at the time of post-processing of the screw hole, coordinate position data corresponding to the post-processed portion and correction data for forming the pilot hole according to the dimensions are added. You may. That is, depending on the content of post-processing, correction data for processing into a shape that is easy to post-process may be added, or correction data that serves as a mark for positioning the post-processing portion may be added.

Further, in the present embodiment, correction data may be generated according to the post-processing location data, or correction data may be stored in advance in the storage unit 14 according to the screw type, screw size, and the like. May be good. In this case, when the post-processing location data is generated, appropriate modification data can be called from the storage unit 14 based on the post-processing location data, and the modification data can be added to the three-dimensional model data.

Next, the three-dimensional model data is generated based on the additional three-dimensional model data to which the post-processing location data is added (S35). On the other hand, when it is determined that there is no post-processing portion (NO in S32), three-dimensional model data is generated based on the three-dimensional model data (S35).

After the three-dimensional model data is generated as described above, the three-dimensional model data generation process is completed, the process returns to the storage process, and the three-dimensional model is executed (S4).

The three-dimensional modeling process will be described below with reference to FIG.

First, the generated three-dimensional model data is acquired (S41).

In the three-dimensional modeled object data, the reference modeled posture data is acquired (S42). The modeling posture data includes the modeling angle, and is, for example, X0Y0Z90 when the reference modeling posture is in the stacking direction, and X0Y0Z0 when the modeling posture is in the horizontal direction orthogonal to the stacking direction. Here, X is the X-axis direction, Y is the Y-axis direction, Z is the Z-axis direction, and each numerical value is an angle. This angle can be set from -180 to 180. For example, when modeling is performed at an angle of 15 degrees in the X-axis direction with reference to the horizontal direction, modeling posture data of X15Y0Z0 is set. Further, when tilting 15 degrees in the X-axis direction and -10 degrees in the Y-axis direction, data of X15Y-10Z0 is set.

Next, a plurality of slice data are generated from the acquired three-dimensional modeled object data based on the acquired modeling posture data (S43). The slice data is cross-sectional shape data in which the three-dimensional model data is divided in the stacking direction for each dimension according to the stacking pitch size, and there are a quantity of the three-dimensional model data divided in the stacking direction. Therefore, it is preferable to sequentially assign numbers and the like to the slice data.

Next, it is determined whether or not it is necessary to change the modeling posture (S44).

As a specific judgment method, after the slice data is generated, the area of the cross section in the data for each stacking pitch is acquired from the generated multiple slice data, and the slice of the cross section having the smallest area is obtained from the acquired area of the cross section. Determine if the data is located above in the stacking direction.

Next, when it is determined that the modeling posture needs to be changed (YES in S44), the modeling posture data is modified and changed (S45).

In the present embodiment, for example, when 40 slice data are generated and the fifth slice data from the bottom in the stacking direction has the minimum area, the fifth slice data comes to the top. , Set the Y-axis data of the modeling posture data to 180 degrees or -180 degrees.

This change in modeling posture is a method in which powder sintering lamination modeling is a method of melting and laminating metal powder. Therefore, when a portion having a small cross-sectional area in the slice data is located on the lower side in the laminating direction, the portion having a small area. When the metal powder located above is melted, heat is transferred to a portion having a small area, and the shape or the like may be deformed. Therefore, when the portion having a small area is not located on the upper side in the stacking direction, it is preferable to modify and change the modeling posture of the three-dimensional modeled object.

In addition, based on a plurality of slice data and three-dimensional modeled object data, a part requiring fine modeling is specified, and the modeling posture is modified and changed so that the minute modeling part is above the stacking direction. It may be.

After modifying and changing the modeling posture data, the process returns to S42 again to acquire the changed modeling posture data and generate slice data.

Here, when modeling is performed not only with the area of the slice data but also with the acquired modeling posture, if the modeling time is longer than the predetermined time, the modeling posture data is modified so that the modeling time is within the predetermined time. You can also change it.

When it is no longer necessary to change the modeling posture (NO in S44), the support setting is executed (S46). The support settings include settings such as the number of support materials that support the three-dimensional model, the position of the support materials, and the length of the support materials.

Next, it is determined whether or not the set support can be removed at the time of post-processing or finish processing (S47).

If the support material cannot be removed by post-processing at the set support position, specifically, the support material cannot be completely removed by post-processing and remains, or at the position where the support is set, after the support material. There is a state where processing and removal cannot be performed. In this case, it is determined that the removal is impossible.

In the present embodiment, for example, the tool data including at least the tool path of the machining apparatus for post-machining and finishing machining is stored in advance, this tool data is called, and the tool path of the tool data is referred to with respect to the support position. Determines whether or not interferes with the three-dimensional model.

Then, when it is determined that the removal is impossible (NO in S47), the support settings and the like are changed (S48). To change the support settings, etc., at least one of the number of support materials, the position of the support materials, the length of the support materials, etc. is modified and changed until the support can be removed. The changed support settings and the like may include fine adjustment of the modeling posture due to the change of the support material.

Then, when it is determined that the removal is possible (YES in S47), three-dimensional modeling is performed (S49). In the present embodiment, it is preferable to generate the device setting data shown in FIG. 8 at the time of three-dimensional modeling. It is preferable that the device setting data includes material information, equipment information, laser irradiation conditions, position information in the modeling area, position information of the processing table, and the like. The device setting data is used as setting data for a modeling device or the like for a three-dimensional modeled object.

In the present embodiment, when the three-dimensional modeled object is modeled, it is also preferable to acquire measurement data for confirming whether the three-dimensional modeled object is modeled according to a predetermined shape, dimension and geometrical tolerance. Here, if the shape, dimensions, and geometrical tolerance of the three-dimensional modeled object do not satisfy the predetermined accuracy, the data may be corrected at the defective part of the three-dimensional modeled object data, and the three-dimensional modeling may be performed again. it can.

After the three-dimensional modeling is performed again as described above, it is also preferable to measure the dimensions of the result product after data correction and acquire the measurement data of the three-dimensional modeled product which is the result product.

When the 3D modeling is completed, the 3D modeling process is completed, the process returns to the storage process, and the 3D model data related to the 3D model corresponding to the customer's mold and the data required for the 3D model are stored ( S5).

An example of the stored data will be described with reference to FIG.

In the stored data 1 of FIG. 9A and the stored data 2 of FIG. 9B, the ID is a unique number for each customer. There are a plurality of mold numbers corresponding to the customer, and the various data described above are stored corresponding to the mold numbers.

As shown in FIG. 9A, the stored data 1 which is the stored data may include at least the mold No., the three-dimensional model data, and the post-processing location data corresponding to the ID. As a result, at least the customer can acquire the product without owning the mold. That is, it is possible to realize a customer's moldless operation.

Preferably, as shown in the figure, the data corresponding to the ID preferably includes the mold No., three-dimensional model data, and the three-dimensional model data in addition to the post-processing location data. Further, it is preferable to store the slice data, that is, the slice data group as one file. As a result, the time required for modeling can be shortened, and by storing the stored data at each stage, it is possible to easily identify problems.

The data to be stored is not limited to this, and as shown in FIG. 9B, the stored data 2 includes an ID and a mold No. Correspondingly, it is preferable that the device setting data, the finishing processing data, and the three-dimensional model measurement data are included. As a result, it is possible to easily manufacture a product with high accuracy according to the customer's request, and by storing the above-mentioned stored data at each stage, it is possible to easily identify problems. In addition to this, when there is a design change such as a minor change of the product, the corresponding mold No. Various data corresponding to can be easily changed based on the design information changed due to minor changes or the like.

(2) Order processing An example of the system flow of order processing will be described below with reference to FIGS. 1 and 10.

When the customer orders a product in a predetermined mold, the three-dimensional model server 3 displays a predetermined order screen on the display unit 22 of the customer terminal 2, and from the displayed predetermined order screen, the customer displays the predetermined order screen. Order processing is performed via the input unit 21 of the customer terminal 2.

At the time of this order processing, the three-dimensional modeled object server 3 authenticates whether or not the customer has a customer ID. The authentication may be a password method, biometrics authentication, or an authentication card may be issued in advance and the card may be input from the customer terminal 2 for authentication. The authentication method is not particularly limited.

Then, when the three-dimensional model server 3 determines that it has the customer ID, the stored data 1 and 2 shown in FIGS. 9 (a) and 9 (b) are displayed on the predetermined order screen to the ID and the mold No. Call the corresponding stored data and accept the customer's order. At this time, it may be called by the mold No.

In the present embodiment, as shown in FIG. 9B, the customer can also assign the customer's product number (model number) corresponding to the mold No. from the customer terminal 2. As a result, the customer can also specify the ordered item by his / her own product number (model number), and can facilitate the customer's order.

When the input is made on the predetermined order screen on the customer terminal 2 and the customer's order is confirmed, the three-dimensional model server 3 has three dimensions corresponding to the ordered quantity and the ID, mold No., or product number. The stored data of the modeled object is transmitted to the business terminal 1 (S6).

Next, when the business operator terminal 1 receives the stored data, it performs three-dimensional modeling based on the stored data (S7).

After the three-dimensional modeling, the post-processing process of the three-dimensional modeled object is executed (S8). Here, the system flow of the post-processing process will be described with reference to FIG.

First, a three-dimensional modeled object modeled in S7 is prepared (S81). Next, the post-processing location data shown in FIG. 6 and the finishing processing data shown in FIG. 12 are recalled (S82).

It is preferable that the finishing processing data shown in FIG. 12 is generated when the post-processing location data of S33 in the storage processing is generated or the correction data is added to the three-dimensional model data of S34. .. As a result, the processing time can be shortened.

As shown in FIG. 12, the finishing processing data includes at least a necessary finishing processing method. Further, the finishing processing data may include a processing program of a processing apparatus for performing a finishing process (not shown).

The post-processing location data and the finishing processing data make it possible to confirm the post-processing location of the three-dimensional model and the conditions of the finishing processing.

Next, post-processing and finishing processing of the three-dimensional modeled object are performed based on the called post-processing location data and finishing processing data (S53). The post-processing is preferably performed by, for example, a cutting device, a heat treatment device, a surface treatment device, or the like, but is not limited thereto.

Below, it is also preferable to add the following processing to the storage processing. An example of the added processing will be described with reference to FIG.

In FIG. 13, in the storage process, the processes of S1 to S5 are the same as the processes of FIG. 2, and therefore the description thereof will be incorporated and the description thereof will be omitted.

In the example of FIG. 13, a post-processing process is executed between S4 and S5 in FIG. 2 (S9). Since the example of the post-processing is the same as the post-processing of S8 (see FIG. 11) in the order processing of FIG. 10, the description thereof will be incorporated and the description thereof will be omitted here.

In the storage process, post-processing and finishing processing can be performed and the measurement data of the final product after these processing can be stored. As a result, it becomes easy to compare the measurement data of the product manufactured at the time of ordering with the measurement data at the time of storage processing, and quality control can be made easier.

Further, it is also preferable to perform a practical inspection (S10) after the treatment of S9. The practical inspection is a process that allows the customer to determine the customer's requirements by providing the customer with the final modeled object finished by S9 before data storage.

Quality control can be further improved by acquiring the measurement data of the final modeled object that has been approved by the customer.

The data obtained by various processes is not limited to the embodiment described in the above embodiment, and the data obtained by the mold No. It is preferable to store it in each case. This makes it possible to realize traceability.
