TECHNICAL FIELD

[0001] The present application relates to the technical field of computer, in particular to a product template and process template combined parameter driven resource reconstruction method and system. BACKGROUND

[0002] In recent years, in the field of typical part process design of special equipment, some enterprises often use Teamcenter system (a leading product lifecycle management system. It is not directly used to create three-dimensional models, but as a central database to manage all product-related data, processes and personnel) to design and manage three-dimensional structured processes, and use NX software (originally named UG, an integrated, full-process computer-aided design, manufacturing and engineering analysis software) to design part templates and three-dimensional process models, but the parameters in the typical part templates and three-dimensional process models are not linked with the process parameters in the Teamcenter system. Some enterprises have developed a cloning structured process function based on Teamcenter system, but the part templates and three-dimensional process models have not been unified cloned and parameter associated. SUMMARY

[0005] Step S1, the NX software acquires the first operation of the user, determines the planning expression of each size in the final product state of the target part according to the first operation, and then completes the full parameter modeling of the target part and the product template release based on the planning expression;

[0006] Step S2, the Teamcenter system acquires the second operation of the user, first determines the initial process procedure structure tree defined based on the target part product template, and then sends a process model set creation instruction to the intermediate plug-in;

[0007] Step S3, the intermediate plug-in automatically creates an initial process model set after receiving the process model set creation instruction, so that the number and sequence of each process model in the initial process model set correspond one-to-one to the process node in the initial process procedure structure tree, and the number and sequence of the working steps in any process model correspond one-to-one to the working step node in the initial process procedure structure tree;

[0008] Step S4, the NX software acquires the third operation of the user, reads the initial process model set according to the third operation, and writes the contents of the working step and the process in each process model completely, and establishes the link between the adaptive change parameter in the edited working step content and the corresponding size in the product template by the process evolution expression to form the target process model set;

[0009] Step S5, after receiving the synchronization instruction sent by the user, the intermediate plug-in synchronizes the process and working step content of each process model in the target process model set to the corresponding process and working step node of the initial process plan structure tree to form the target process plan structure tree, and after receiving the publishing request sent by the user after checking that there is no error, the target process plan structure tree, the target process model set, the product template and the link relationship between the adaptive change parameter in each working step content in the target process plan structure tree, the target process model set and the product template are integrally encapsulated, and then the Teamcenter system is used to complete the publishing of the encapsulated process template;

[0010] Step S6, in the copy environment formed by cloning the process template, after acquiring the size reassignment operation of the product template copy by the user, the intermediate plug-in drives the related parameters in the target process plan structure tree copy and the target process model set copy to complete adaptive change according to the link relationship, so as to realize the resource reconstruction of the type spectrum management.

[0012] Preferably, the second operation sets the process plan structure tree process resource node, and after the synchronization processing of the process and working step nodes and the process model is completed, the Teamcenter system is used to create the association relationship between the working step and / or process content and the process equipment resource independently of the NX software before the process template is published.

[0013] Preferably, in step S4, the NX software reversely calls the "WAVE geometric link + synchronous modeling" function according to the process sequence in the initial process model set to realize the arrangement of the process model and the generation of the process drawing.

[0029] The embodiments of the present application are described in detail below with reference to the accompanying drawings, but the present application can be implemented in various different ways limited and covered by the claims.

[0030] Embodiment 1

[0031] The embodiment discloses a product template and process template combined parameter driven resource reengineering method, which is applied to the integrated environment of Teamcenter system and NX software built by intermediate plug-in, as shown in Figure 1 The method comprises at least the following steps S1 to S6.

[0032] Step S1, the NX software acquires a first operation of a user, determines a planning expression of each size in a final product state of a target part according to the first operation, and completes full-parameter modeling of the target part and product template publishing based on the planning expression.

[0033] Optionally, in this step, the first operation can specifically include the following substeps:

[0034] Step S11, analyzing a typical part drawing, extracting size parameters to be controlled according to part functions and machining process characteristics, as shown in Figure 1 .

[0035] Step S12, planning a typical part size expression based on the extracted size parameters, planning expression names corresponding to main sizes: L = 20: L1 = 15; L2 = 6; L3 = 4; L4 = 2; D1 = 7; D2 = 3; D3 = 12; D4 = 8; D5 = 10, as shown in Figure 2 and Figure 3 .

[0036] Step S13, based on the NX software sketch, feature modeling function, custom expression is applied to the modeling process, to complete the key features of the typical parts of the full parameter modeling based on custom expression.

[0037] Step S14, in the NX software product template studio module based on the typical parts of the size chart, custom expression and other elements to complete the typical parts of the reuse dialog box production, the release of the typical parts of the template.

[0038] Step S2, Teamcenter system obtains the second operation of the user, determines the initial process plan structure tree based on the target part product template definition, and sends a process model set creation instruction to the intermediate plug-in.

[0039] In this step, the structure of the initial process plan structure tree is as shown in Figure 4 Optionally, the user can edit the content based on the initial process plan structure tree, or only define the architecture of the process plan structure tree, and the content is improved based on subsequent steps.

[0040] Step S3, the intermediate plug-in automatically creates an initial process model set after receiving the process model set creation instruction, so that the number and order of each process model in the initial process model set correspond one by one to the process node in the initial process plan structure tree, and the number and order of the process steps in any process model correspond one by one to the process step node in the initial process plan structure tree.

[0041] In this step, the number and order of each process model in the initial process model set correspond one by one to the process node in the initial process plan structure tree, which can be referred to Figure 5 .

[0042] Step S4, the NX software obtains the third operation of the user, reads the initial process model set according to the third operation, and writes the process step content and process content in each process model, and establishes a link between the adaptive change parameter in the edited process step content and the corresponding size in the product template with the process evolution expression to form a target process model set.

[0043] In this step, the NX software reversely calls the "WAVE geometry link + synchronous modeling" function according to the process sequence in the initial process model set to realize the arrangement of the process model and the generation of the process drawing. Referring to Figure 6 , the order of the process model is arranged in reverse order according to the process sequence in the initial process model set: inspection process model, finishing process model, semi-finishing process model, roughing process model, and blanking process model.

[0044] The link path of the adaptive change parameter in the target process model set is as shown in Figure 7As shown in the figure, the link between different rows represents the sequence of different processes, the different columns in the same row represent the sequence of process steps, and the boxed values are the specific values of the adaptive change parameters.

[0045] In this step, the reference Figure 8 , the so-called "process evolution expression" is based on the evolution of the process, and the change law of each parameter of the blank is deduced according to the planning expression of each size in the product template; The change law can be represented by a formula, for example: in Figure 8 The process template editing interface shown in the figure, the " +1 " in the expression list in the upper left corner of the figure can represent that the processing result of the parameter (D4 or D5) in the current process template is to increase 1mm based on the value of the linked same parameter (D4 or D5) in the product template (04085 / L01 represents ID / version information).

[0046] Step S5, after receiving the synchronization instruction sent by the user, the intermediate plug-in synchronizes the process and process step content of each process model in the target process model set to the process and process step nodes corresponding to the initial process plan structure tree to form the target process plan structure tree, and after obtaining the publishing request sent by the user after checking that there is no error, the target process plan structure tree, the target process model set, the product template and the adaptive change parameters in each process step content are linked between the target process plan structure tree, the target process model set and the product template. After the Teamcenter system completes the release of the encapsulated process template.

[0047] Step S6, in the copy environment formed by cloning the process template, after obtaining the size reassignment operation of the user on the product template copy, the intermediate plug-in drives the adaptive change of the related parameters in the target process plan structure tree copy and the target process model set copy according to the link relationship to realize the resource reconstruction of the type spectrum management. Wherein, the cloning process can refer to Figure 9 .

[0048] Preferably, the second operation of the embodiment further includes setting process drawing nodes in the initial process plan structure tree (refer to Figure 5 The intermediate plug-in creates process drawings corresponding to each process drawing node in each process model in the initial process model set (refer to Figure 6 to Figure 8The NX software generates parameter-driven process drawing based on the written content of each process model; the intermediate plug-in writes each process drawing into the process drawing node corresponding to the target process plan structure tree, and adds the parameter-driven relationship of each process drawing when packaging the process template, so that the process drawing in the target process model set is adaptively changed with the size reassignment operation of the product template copy and is synchronized to the target process plan structure tree copy in the copy environment formed by cloning the process template.

[0049] Further, the process resource node (refer to Figure 5 , including but not limited to processing equipment and other resources) of the process plan structure tree is set in the second operation of the embodiment, and the association between the process step and / or process content and the process equipment resource is created by the Teamcenter system independently of the NX software after the synchronization processing of the process and step nodes and the process model is completed and before the process template is published.

[0052] In summary, the method and system disclosed in the above two embodiments of the present application realize the resource integration and data penetration of the "product template + target process plan structure tree + target process model set + parameter adaptive linkage relationship" based on the process step parameter level in the final process template in the integrated environment of the Teamcenter system and the NX software built by the intermediate plug-in through clear division of labor and cooperation, so that the related parameters in the target process plan structure tree copy and the target process model set copy can be adaptively changed with the size adjustment of the product template copy in the copy environment formed by rapid cloning, thereby greatly improving the process preparation efficiency and quality in the typical part spectrum management process.
