Modes for Carrying Out the Invention

[0013] (1. Flow of Production Preparation) The flow of workpiece production preparation will be described with reference to FIG. 1. The workpiece is an object produced by machining. For example, the workpiece is a mold. The mold is an object for small batch production and is, for example, a one-of-a-kind workpiece.

[0014] As shown in Fig. 1, for the production preparation of a workpiece, first, the design of the workpiece is carried out (S1). In the design of the workpiece, design drawing data and the like are created. The design drawing data is two-dimensional data or three-dimensional data. Subsequently, based on the design drawing data and the like, the design of the production process is carried out (S2). The design of the production process includes the sequence of the production process for producing the workpiece. The production process includes, for example, material preparation, each process of machining (cutting, polishing, plastic processing, laser processing, etc.), heat treatment, surface treatment, and the like. In the production design process, a production process design document is created.

[0015] Subsequently, based on the production process design document, a machining path and the like are created by CAD / CAM (S3). Subsequently, based on the created CAD / CAM, a simulation is carried out to obtain the predicted machining time and the like (S4). Then, a machining instruction document is created (S5), and a production process table is created (S6).

[0016] (2. Production Process Design Document and Production Process Table) An example of the production process design document created in the production process design (S2) will be described with reference to Fig. 2. As shown in Fig. 2, the production process design document 1 includes at least "Process No.", "Process", and "Content". The "Process" includes "Classification" representing the large framework of the process and "Detailed Process" representing the equipment and processing method.

[0017] The "Classification" includes a material process for preparing materials (raw materials), a rough machining process among machining processes, a finishing machining process among machining processes, a high-precision machining process among machining processes, a polishing process, a heat treatment process, a surface treatment process, and the like. The "Detailed Process" includes the name of the material supply manufacturer as the material supply method, the type of machining equipment, the name of the machining implementation manufacturer, the type of heat treatment and surface treatment equipment, the name of the heat treatment and surface treatment implementation manufacturer, and the like. As the machining equipment, for example, in the case of a machining center, it is set as different equipment types according to the machine model and the type of held tools. The "Content" describes arbitrary matters. For example, it includes the type of material, the size of the allowance, the target physical property values such as surface roughness (Ra, Ry, etc.) and surface hardness.

[0018] Figure 2 shows the production process design document 1 of the mold. This production process design document 1 describes, in order, the material process by Manufacturer A, the rough machining process by Lathe 1, the rough machining process by Machining Center 1, the heat treatment process by Manufacturer Y, the finish machining process by Machining Center 2, and the polishing process by Grinder 1.

[0019] Next, an example of the production process table 2 created after the simulation will be described with reference to Figure 3. The production process table 2 includes, in addition to the information contained in the above-described production process design document 1, the schedule of the production schedule and the estimated man-hours (setup, processing). The schedule of the production schedule, the estimated man-hours, etc. are information obtained by the simulation (S4) in Figure 1.

[0020] (3. First Example of the Production Process Design System 10) The first example of the production process design system 10 will be described with reference to Figures 4 - 8. The production process design system 10 is a system that automatically creates the production process design document 1 shown in Figure 2. Furthermore, the production process design system 10 is a system that automatically creates the production process table 2 shown in Figure 3.

[0021] As shown in Figure 4, the production process design system 10 includes a storage device 20 that stores the knowledge model 20a and a production process design device 30 that designs the production process based on the knowledge model 20a.

[0022] The knowledge model 20a stores knowledge related to information in the technical field of workpiece production in a predetermined format. That is, the knowledge model is mainly composed of a plurality of factors defined by technical terms in the field and relationship information between the factors.

[0023] The knowledge model is represented, for example, by data having information about factors and data having relationship information. As a concept, the knowledge model expresses the relationship between factors by connecting a plurality of factors in a network form. That is, the knowledge model stores knowledge (including know-how) in various technical fields as formal knowledge and can be updated.

[0024] An example of a knowledge network diagram representing the knowledge model 20a in a network diagram is shown in FIG. 5. As shown in FIG. 5, the knowledge model 20a includes, as factors, "specifications of the workpiece". The specifications of the workpiece include, as specifications 1, the component configuration of the die as the workpiece, the presence or absence of heat treatment, etc. The specifications of the workpiece define, as specifications 2, a part of the shape of the die as the workpiece. Specifications 2 include, for example, the die size, the necessity of dividing machining, etc. The specifications of the workpiece define, as specifications 3, another part of the shape of the die as the workpiece. Specifications 3 define the shape to be machined and include, for example, hole machining, cylindrical machining, surface machining, etc.

[0025] The knowledge model 20a further includes, as factors, the "classification" of the production process. The classification includes a material process, a rough machining process, a finishing process, a high-precision machining process, etc. The knowledge model 20a further includes, as factors, the "detailed process" of the production process. The production process is associated with the classification and includes at least one of the equipment and processing methods for realizing the classification. The detailed process includes lathes 1, 2, machining centers 1, 2 (MC), grinding machines, heat treatment machines, surface treatment machines, machining manufacturers, heat treatment manufacturers, surface treatment manufacturers, material supply manufacturers, etc.

[0026] The knowledge model 20a further includes, as factors, a "process pattern" defined by the combination of classifications and the order of classifications. The process pattern includes process pattern A, process pattern B, etc. and is composed of one or more classifications. Process pattern A includes, for example, a material process and a high-precision machining process, and process pattern B includes, for example, a rough machining process, a heat treatment process, a finishing process, and a polishing process.

[0027] The knowledge model 20a defines the relationship information between factors. In the network diagram shown in FIG. 5, the relationship information between factors is shown as a link figure (e.g., a line, an arrow line) connecting the factors. The relationship information is defined by, for example, qualitative information or quantitative information.

[0028] The knowledge model 20a may be set by an operator, for example, or may be automatically set by a computer using natural language processing technology, database technology for various types of expert knowledge, etc. Of course, the knowledge model 20a may be edited by an operator after being automatically set by a computer.

[0029] Based on the knowledge model 20a stored in the storage device 20, the production process design apparatus 30 automatically creates the production process design document 1 and the production process table 2. As shown in FIG. 4, the production process design apparatus 30 includes a design information acquisition unit 31, a process pattern determination unit 32, a classification acquisition unit 33, a detailed process determination unit 34, a production process table creation unit 35, and an output unit 36.

[0030] The design information acquisition unit 31 acquires the design information of the workpiece as the object of production process design. That is, the design information acquisition unit 31 acquires the design data (for example, design drawing data) as the design information of the workpiece when the design data is input by an operator, for example.

[0031] The process pattern determination unit 32 determines a process pattern based on the design information of the workpiece using the knowledge model 20a. As described above with reference to FIG. 5, a number of process patterns are stored in the knowledge model 20a. The process pattern is associated with the specifications of the workpiece as the design information of the workpiece. Specifically, the process pattern is associated with the "specification 1" information as the specifications of the workpiece, for example, component configuration, heat treatment, etc., and is also associated with the "shape 1" information as the specifications of the workpiece, for example, mold size, presence or absence of broaching, etc.

[0032] Therefore, as shown in FIG. 6, the process pattern determination unit 32 determines one process pattern (for example, process pattern B) that conforms to the design information of the workpiece from among a number of process patterns A, B, C stored in the knowledge model 20a. Also, the process pattern determination unit 32 may determine a plurality of process pattern candidates.

[0033] The classification acquisition unit 33 acquires a combination of classifications and the order of classifications corresponding to the determined process pattern using the knowledge model 20a. As described above with reference to FIG. 5, in the knowledge model 20a, a plurality of classifications of production processes are associated with each of the process patterns. For example, as shown in FIG. 7, it is assumed that the process pattern B is associated with a material process, a rough machining process, a heat treatment process, a finishing process, a polishing process, and the order thereof. Therefore, as shown in FIG. 6, when the process pattern B is determined by the process pattern determination unit 32, as shown in FIG. 7, the classification acquisition unit 33 acquires the classifications and the order of classifications associated with the process pattern B in the knowledge model 20a.

[0034] The detailed process determination unit 34 determines, for each of the classifications acquired by the classification acquisition unit 33, a detailed process and the order of the detailed processes based on each of the classifications and the design information of the workpiece using the knowledge model 20a. As described above with reference to FIG. 5, in the knowledge model 20a, detailed processes of the production process are associated with each of the classifications of the production process. For example, although not shown, manufacturer A, manufacturer B, manufacturer C, etc. are associated with the material process, and lathes 1, 2, 3, machining centers 1, 2, 3 (MC), laser processing machines 1, 2, 3, etc. and the order thereof are associated with the rough machining process. Manufacturer X, manufacturer Y, manufacturer Z, etc. are associated with the heat treatment process, and lathes 1, 2, machining centers 1, 2, 3, grinding machines 1, 2, 3, etc. and the order thereof are associated with the finishing process. Grinding machines 1, 2, 3, lapping machines 1, 2, 3, etc. are associated with the polishing process.

[0035] And, as shown in FIG. 5, the detailed processes are associated with the specifications of the workpiece as the design information of the workpiece. Specifically, the detailed processes are associated with the "shape 2" information as the specifications of the workpiece, for example, machining methods such as hole machining, cylindrical machining, and surface machining.

[0036] Therefore, as shown in FIG. 8, the detailed process determination unit 34 determines, for each classification, the detailed processes that match the design information of the workpiece and their order from among the numerous detailed processes stored in the knowledge model 20a. For example, as the material process, manufacturer A is determined, and as the rough machining process, lathe 1 and machining center 1 and their order are determined. As the heat treatment process, manufacturer Y is determined, and as the finishing process, machining center 2 is determined. For the polishing process, grinding machine 1 is determined.

[0037] Then, based on each classification and the order of classifications, and each detailed process and its order within each classification, the detailed process determination unit 34 creates a production process design document 1 as shown in FIG. 2. Also, the matters described in the content column in FIG. 2 can be obtained, for example, by calculation considering the specifications of the workpiece when determining the detailed processes. Alternatively, it may be described by the operator.

[0038] As shown in FIG. 1, based on the production process design document 1, after creating CAD / CAM (S3), by performing simulation (S4), man-hour estimate information can be obtained. Therefore, the production process table creation unit 35 creates a production process table that includes the schedule of the production schedule and the man-hour estimate information in addition to the information included in the production process design document 1. The production process table may include information other than the schedule of the production schedule and the man-hour estimate information.

[0039] The output unit 36 outputs the created production process design document 1. That is, the output unit 36 outputs the classification and the order of classifications, as well as the detailed processes and the order of detailed processes. Furthermore, the output unit 36 outputs the created production process table 2.

[0040] As described above, the knowledge model 20a is a model composed of a plurality of factors and relationship information between the factors. The factors are defined by technical terms related to the production of workpieces. Furthermore, the factors include workpiece specifications, classification of production processes, detailed processes including at least one of facilities and processing methods associated with the classification and realizing the classification, and process patterns defined by combinations and orders of classifications. That is, the knowledge model 20a models the knowledge of skilled workers regarding the production of workpieces in general, not limited to specific workpieces.

[0041] Then, the production process design device 30 uses the knowledge model 20a to design a production process for producing a workpiece by machining. And the production process design device 30 automatically outputs the production process design document 1 shown in FIG. 2. In particular, the production process design device 30 uses the knowledge model 20a to determine a process pattern, acquire the classification and its order corresponding to the process pattern, and determine the detailed process and its order for each of the classifications. That is, when the design information of the workpiece to be designed is input, the production process design device 30 can use the knowledge model 20a to determine a production process suitable for the design target, that is, classification, order of classification, detailed process, and order of detailed process. Therefore, the design of the production process of the workpiece to be designed can be performed without relying on skilled workers.

[0042] Furthermore, in addition to the production process design document 1, the production process design device 30 automatically outputs a production process table 2 including a production schedule and an estimate of man-hours as shown in FIG. 3. Since the production process table can also be automatically output, there is no need to create the production process table manually.

[0043] (4. Second Example of Production Process Design System 110) The production process design system 110 of the second example will be described with reference to FIGS. 9 to 11. In the production process design system 110 of the second example, the same components as those in the production process design system 10 of the first example are denoted by the same reference numerals, and the description thereof will be omitted. The production process design system 110 of the second example is different from the first example in that it includes an order adjustment knowledge database (DB) 140 and an order change processing unit 131.

[0044] The order adjustment knowledge database 140 stores knowledge data for adjusting the order regarding the order of the classifications acquired by the classification acquisition unit 33 and the order of the detailed processes determined by the detailed process determination unit 34. The order change processing unit 131 uses the order adjustment knowledge database 140 as input information to change the order of the classifications or the order of the detailed processes.

[0045] As shown in FIG. 10, the order change processing unit 131 changes the order of the detailed processes before the change. In this case, considering the order adjustment knowledge database 140 for the detailed processes before the change, the fourth detailed process of the lathe 2 before the change is moved between the detailed processes of the grinding machine 2 and the machining center 2. After the change, the target detailed process is described as lathe special 2. Note that in this example, "special" means the detailed process after the change.

[0046] Also, a specific example of the order change processing unit 131 is shown in FIG. 11. For example, when the mold size of the die is large, it is necessary to form a throw-away boss on the die. Suppose such knowledge is stored in the order adjustment knowledge database 140. In this case, once the detailed processes before the change shown in FIG. 11 are determined in the processing up to the detailed process determination unit 34. Considering the above information in the order adjustment knowledge database 140 for the detailed processes before the change, the grinding machine 1 is moved before the lathe 1. After the change, the target detailed process is described as grinding machine special 1.

[0047] Thus, in special cases, it is possible to change the order, and furthermore, the order change in special cases is performed using information obtained by databaseizing the knowledge of skilled workers. Therefore, considering the knowledge of skilled workers, the order can be automatically changed.

[0048] (5. Third Example Production Process Design System 210) The third example production process design system 210 will be described with reference to FIG. 12. In the third example production process design system 210, the same components as those in the second example production process design system 110 are denoted by the same reference numerals, and the description thereof is omitted. The third example production process design system 210 is different from the second example in that the information acquisition unit 250 is different.

[0049] The information acquisition unit 250 acquires at least one of the operating status of the equipment and the production plan of the workpiece. The operating status of the equipment is not limited to the actual operating status of the equipment, but includes the operating plan status of the equipment. The workpiece production plan includes the delivery date and the like for a plurality of target workpieces.

[0050] The order change processing unit 131 uses, as input information, in addition to the order adjustment knowledge database 140, the information acquired by the information acquisition unit to change the classification order or the detailed process order. For example, when the equipment is undergoing regular maintenance or abnormal maintenance, the equipment cannot be used. In such a case, it is necessary to design a production process that does not use the equipment. Also, when the production processes of other workpieces have already been designed for priority, the equipment used in those other workpieces cannot be used in the production process of the target workpiece. In such a case, it is necessary to design a production process that does not use the equipment or a production process that changes the timing.

[0051] Therefore, the order change processing unit 131 uses the operating status and production plan acquired by the information acquisition unit 250 to change the classification order and the detailed process order, thereby designing an overall efficient production process plan.
