The MBD method is based on digital design, and the geometric model, the function definition and other related information are uniformly bound together to form a comprehensive and consistent design model. The model-driven design method not only can provide visual effect, but also can reduce the use of design paper documents and 2D drawings, and realizes comprehensive digitization and consistency management of design information.
The MBD method is a design method based on a graphical modeling tool, can promote system design and development from a traditional code layer to a model layer, carries out system modeling and automatically generates codes through the graphical modeling tool, and improves development efficiency and system reliability.
The expression and organization of the non-geometric information of the part process information model based on the MBD method mainly comprises the definition of the part process information model, the organization structure of the process information model and the expression of the non-geometric information of the MBD process information model.
Aiming at the problems of inconsistent design and low development efficiency in the design process of the existing product development system, the application provides a method, a device and equipment for creating a model definition MBD process model.
As shown in fig. 1, an embodiment of the present application provides a method for creating a model definition MBD process model, including:
step 101: obtaining modeling information corresponding to a production process; the modeling information includes at least one of: process attribute information of the part; processing technology information; processing characteristic information; and (5) process marking information.
In the step, firstly, determining system design targets and demands, and converting the designs of physical products and systems into mathematical models by adopting a digital modeling technology to obtain modeling information corresponding to a production process, wherein the modeling information comprises process attribute information, processing process information, processing characteristic information and process labeling information of parts;
the process attribute information of a part is mainly associated with an MBD method design model (MBD process model), and is generally composed of information expressing the design intent of the part (for example, part name, part number, work order number, etc.).
The processing technology information refers to the design planning of the processing technology process of the part according to the existing technology knowledge base and manufacturing resource base under the guidance of the MBD method design model, and in the planning technology process, each working procedure and each working step have the corresponding information of processing size, processing surface, processing allowance, cutter, clamp, measuring tool and the like, and the information corresponding to the working procedure, the working step and the like is determined as the processing technology information.
In the processing and manufacturing process of the parts, processing characteristic information exists as the most basic unit of process planning and process design, a geometric area formed by continuous feeding movement of a cutter is the processing characteristic area corresponding to the parts, the processing characteristic information is a processing unit corresponding to each processing procedure in the process design and is a geometric entity containing the processing technology information, and corresponding procedure design can be carried out according to the determined processing characteristic information and the corresponding manufacturing resources.
The process annotation information comprises process marking information and process annotation information, and in the modeling process of the MBD method process model, technical requirements such as some heat treatment methods, unnoticed information on parts and the like are required to be displayed on the process model in a marking and annotation mode.
The information may be implemented by various computer aided design (Computer Aided Design, CAD) software and computer aided engineering (Computer Aided Engineering, CAE) analysis tools.
It should be further noted that, data management and integration are a very important ring in the whole MBD process, and the above information needs to use software such as database, product data management (Product Data Management, PDM), product life cycle management (Product Lifecycle Management, PLM) to implement data management, transmission, timely update and protection.
Step 102: and obtaining a sub-process model corresponding to each processing process according to the modeling information.
The MBD Process Model (PM) is composed of Process information such as Process characteristic information, process attribute information, process information, and Process label information of each Process stage in the Process of manufacturing, and is defined as follows:
wherein F is i And the ith processing characteristic information which is to be processed in the stage of the processing procedure is shown.
Note j Representing process annotation information such as surface accuracy, roughness, etc.
Mark k Representing process marking information such as positioning, clamping references, etc.
Processing process information related to the process model, such as a process name and a process content, and process attribute information of the component, which indicate the processing stage.
Step 103: and linking the sub-process models to obtain a model definition MBD process model.
In the step, the sub-process models corresponding to each processing process are linked according to the planned process route, and thus the creation of the model definition MBD process model is completed.
Specifically, when the sub-process models corresponding to the respective machining processes are linked, information such as machining process information and process attribute information of the parts is linked to the MBD process model.
The MBD process model is used as a main information carrier of the process information model, and is realized by combining information such as processing process information and the like on the basis of an MBD design model and performing gradual modeling according to a design processing route, wherein the MBD process model is related to the information such as the processing process information and the like related to the process. The MBD process information model based on the parts is used as the only basis and carrier in the production and manufacturing process, is an aggregate of all MBD process models, and simultaneously comprises all geometric information and basic process information of the MBD design model.
In an alternative embodiment, according to the modeling information and the process route, obtaining a sub-process model corresponding to each processing process includes:
and obtaining the sub-process model corresponding to each processing process according to the modeling information and in a mode of removing the processing characteristics.
It should be noted that, the MBD process model generally has two modeling methods, namely, a forward modeling method and a reverse modeling method; the forward modeling method is a modeling method for forming a product design model by gradually removing a geometric feature domain from a blank model; the reverse modeling method is a modeling method for gradually adding a geometric domain from a product design model to form a blank model, and in the embodiment, a forward modeling method is adopted.
Specifically, according to the planned process route, part processing is performed from a blank by removing a processing characteristic field under the guidance of processing process information, and in the process of finally generating an MBD process model, each intermediate model corresponding to each process is a created sub-process model, and the creation of the MBD process model is completed by linking process attribute information, processing process information and the like related to the process in the sub-process model into the model.
Since the MBD Process Model (PM) is a series of Process Model geometries built from a blank by removing geometric feature regions continuously according to a designed processing route based on an MBD design Model, the blank Model can be regarded as a first Process Model and the design Model as a last Process Model. Therefore, the MBD process model M is defined as follows:
or (b)
In the above two formulas, G DM The three-dimensional geometry representing the MBD process model is composed of simple three-dimensional geometric elements such as geometric elements and auxiliary geometric elements of the model, and PM i A sub-process model representing the ith processing process of the corresponding process information model;processing technology information corresponding to the jth procedure is represented; />Processing characteristic information indicating the sub-process model.
The MBD process model obtained in the above manner is composed of a full three-dimensional geometric information model that embodies the function of the part and basic process information that expresses the part name, material, surface roughness, heat treatment method, and the like.
The MBD process model is used as a main carrier of the processing technology information, and is based on the MBD design model and the processing technology information is used as modeling guidance. The MBD process model is an aggregate of process attribute information (e.g., process design of a part) and machining process information (e.g., process dimensions and tolerances, machining requirements, machining tool, jig, gauge, cutting parameter information, etc.) of parts in each machining process in the machining and manufacturing process of the part, and is established for expressing the machining process of the product.
Layering requirements of the MBD process model are that non-geometric information contained in the model is organized in a layering mode in a mode of facilitating model viewing, and in an optional embodiment, each sub-process model corresponding to each processing process comprises a geometric layer model layer and an attribute model layer;
obtaining a sub-process model corresponding to each processing process according to the modeling information, wherein the sub-process model comprises the following steps:
labeling the process labeling information on a geometric layer model layer in a sub-process model corresponding to each working process; and labeling the process attribute information of the part in an attribute model layer in a sub-process model corresponding to each process.
Specifically, the information needing three-dimensional labeling in the process labeling information, such as size information, tolerance information, roughness information, technical requirement information and the like, can be directly labeled on the model according to corresponding procedures on the model geometric layer, and the process attribute information of the part, such as part name, model number, material and the like, which are not directly related with the model, can be labeled on the attribute model layer through the shape of the model attribute information table.
In an alternative embodiment, the method further comprises:
and checking the process marking information to obtain a checking result.
In the optional embodiment, a model verification tool is utilized to perform model verification on process labeling information in the MBD process model, wherein the process labeling information comprises consistency, correctness, feasibility and the like of the model, and a verification result is obtained.
Further, the process annotation information is checked to obtain a check result, which comprises the following steps:
generating a test case according to a preset verification requirement;
and according to the test case, checking the process marking information to obtain a checking result.
When the process marking information in the MBD process model is verified, a test case is automatically generated according to a preset verification requirement, the model is comprehensively tested through the automatically generated test case, and whether the performance and the function of the model meet the design requirement is checked.
The feature surface of the entity has basic attributes such as roughness, reference, shape tolerance, position tolerance and the like, and the correctness of the feature surface is checked in the labeling and prompts are given. For example, a surface is marked with roughness, and re-marking can generate conflicting cues without creating an over-defined state. The same is true of the reference attribute, and the generated reference or the attached reference on the surface can be accurately known when the software reads. The various types of shape and position tolerances will also correspond to related attributes, facilitating detection of non-matching attributes or over-defined conditions.
In the verification process of the three-dimensional labeling, the guarantee of the correctness of the three-dimensional labeling information involves four aspects: existing three-dimensional annotation data information, an object to which the three-dimensional annotation data information is bound, three-dimensional annotation data information to be added and an object to which the three-dimensional annotation data information is bound. The process for ensuring the accuracy, uniqueness and completeness of the three-dimensional annotation data is divided into at least five steps, namely, further, the process annotation information in the geometric layer model layer is verified, and the process annotation information comprises at least one of the following steps:
according to a preset principle, checking process marking information in the geometric layer model layer, namely, performing basic checking on data, wherein the purpose is to ensure that data elements are complete and data are accurate, and checking of some basic principles of the geometric layer model layer, such as checking that the upper limit value is larger than the lower limit value, and the limit value which is not smaller than zero cannot be smaller than zero, is related;
checking whether corresponding reference data exist for the process marking information marked in the geometric layer model layer, namely checking whether the reference data exist in the existing data, for example, when the position tolerance is used for the reference object, a reference relation needs to be generated, and when the reference is deleted, the corresponding position tolerance object should be prompted and destroyed to ensure the accuracy of the data;
for the process marking information to be marked, checking whether the same type of information exists in the marked process marking information in the geometric layer model layer, namely checking whether the type of the data to be marked exists in the existing data, for example, a plurality of form and position tolerances can be marked on the same object at times, but the same form and position tolerance cannot be marked without limit, so that whether the type of data exists is checked before marking;
for the information to be annotated, checking whether there is a conflict in the process annotation information annotated in the geometric layer model layer, namely checking whether there is a conflict between the object to be annotated and the existing object, for example, prompting should occur when the reference code which has been used is used, or only providing the operator with 'residual' selection to control the reference code not to conflict. Adding a reference to a certain surface requires knowing whether the surface is marked with the reference or not, specifically, the data node of the surface is found in the data first, and whether the reference exists or not is found. If the specific functional group is not present, the specific functional group is not defined and can be added; presence indicates defined, prompting conflict. Similar checks should be made also when creating form and position tolerances and roughness;
checking whether the marked process marking information in the geometric layer model layer is matched with the marked object, namely determining whether the object type is matched, for example, when the flatness is marked on a cylindrical surface or the cylindricity is marked on a plane, whether the object type is matched with the data or not should be detected, and if the object type is not matched with the data, the system should make a corresponding prompt;
the process annotation information comprises the process annotation information marked in the geometric layer model layer and the process annotation information to be marked.
Further, the method further comprises:
and correcting and optimizing the MBD process model according to the verification result to obtain a corrected MBD process model, and carrying out model verification and information verification again until the model meets the design requirement.
