[0044] In the process of implementing this application, the inventor discovered that the current product processing in the manufacturing industry is in urgent need of a complete, advanced, customized system that can perform processing programming and navigation.

[0045] In response to the above problems, embodiments of the present application provide a machining programming navigation system, method, computer device and storage medium.

[0046] The solutions in the embodiments of the present application can be implemented in various computer languages, for example, object-oriented programming language Java and interpreted scripting language JavaScript, etc. In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0047] See also Figure 1 The present application embodiment provides a machining programming navigation system 100, which at least includes: a model information extraction module 101, a part analysis module 102, a process planning module 103, a three-dimensional process model generation module 104 and a navigation module 105, see Figure 2 and Figure 3 , each module is specifically used for:

[0048] 1) Model information extraction module 101, used to extract basic part information of the part to be processed;

[0049] The basic part information can be extracted based on the part to be processed or based on the model of the part to be processed. Generally, when the part model is constructed, the substrate contains most or even all of the part substrate information. As the only data source of the system, the part model contains rich management information, geometric information and non-geometric information. Especially in the 3D process planning stage, in addition to the basic part information, modeling feature information, annotation information, etc. can also be extracted.

[0050] Select the product design model to be processed in the system. The system obtains basic part information such as part name, code, material, product name, code, blank type, etc. from the model of the part to be processed. Based on the material model information, the subsequent process property inference is used to obtain the material properties from the resource library. When the part blank is generated later, different blank generation strategies can be adopted according to the specified blank type.

[0051] 2) A part analysis module 102, used to determine the processing feature information of the part to be processed according to the basic information of the part;

[0052] Analyze the information that can be understood by the process from the basic information of various parts in the part model, and convert the design intent into processing feature information used to characterize the process requirements. This module takes the smallest processing object (processing feature) as the associated object, and mainly analyzes the processing features of the parts and their properties and dimensions. For the marked dimensions (design requirements), the marking is converted into the process attributes of the features through analysis.

[0053] The part analysis module can effectively identify the relevant manufacturing features on the three-dimensional model through the automatic recognition function of manufacturing features, which serves as the basis for the subsequent intelligent generation of feature processes. The manufacturing features may include, but are not limited to: external cylindrical surface, overtravel groove, shaft end face, hole, A-type keyway, C-type keyway, half-moon keyway, stepped hole, plane, shaft step, external conical surface, center hole, external thread, internal thread, internal chamfer, external chamfer, hole step, groove, inclined rib surface, hole system, internal chamfer system, straight groove, internal conical surface, countersunk hole, ring groove, etc. The part analysis module supports multiple ways of automatic recognition of manufacturing features, and the system provides a wealth of practical functions to identify features. For simple features, the system can automatically analyze, and for complex features, they can be specified through interaction with the user. For example, for grooves, multiple recognition modes including "T-type milling cutter" are provided. For process features, in addition to identifying the feature type, the parameters of the feature can also be identified, as well as the identification and utilization of the tolerance and roughness information associated with the feature marked on the design model, which is convenient for subsequent process design.

[0054] 3) A process planning module 103, used to determine the process information of the part to be processed according to the processing feature information;

[0055] The process planning module infers the processing method (route) and processing allowance of the feature from the knowledge base according to the processing features and feature attributes (process requirements). Then, according to the basic principles of process compilation and process resources, the processing methods of the features are reorganized and arranged to form the processing procedures (route) of the parts. Finally, according to the machine tool, features, allowance, etc., the tool and processing parameters of each step are inferred from the knowledge base. Through the above three processes of feature processing step reasoning, part process arrangement, and step reasoning, the process information of the part processing process is formed.

[0056] The process planning module supports feature-oriented, knowledge-based process reasoning: The embodiment of the present application adopts a knowledge-based intelligent process reasoning process to support process design based on typical processes and knowledge-based process decisions. Based on process feature reasoning, processing features can be sorted, merged and reorganized to quickly form a part process structure, thereby improving process determination efficiency.

[0057] In the machining programming navigation system provided in the embodiment of the present application, features, feature attributes, and feature processing methods are related, and the geometric shape and dimensional parameters of the features are identified, and these data are used for processing method reasoning. At the same time, the machining programming navigation system can perform processing method reasoning of process features on the basis of feature recognition and feature parameter extraction, obtain the processing method of the features, maximize the value of design data, and further improve machining efficiency. Processing method reasoning, based on a customizable reasoning process, is an open and maintainable knowledge base, which greatly improves the flexibility of machining programming.

[0058] The initial reasoning of the processing method can be manually input by the process personnel. The machining programming navigation system can fully identify all the features of most parts and infer their processes. Most of the features of the remaining small part of the parts can also be recognized and inferred. A small number of unrecognizable part features or processes are not pre-defined in the machining programming navigation system. Users are supported to intervene in the reasoning process, or directly manually input feature processing methods to form part processes. For the process compilation of sporadic features of a small number of parts that are not covered temporarily through configuration and development of the machining programming navigation system, users are supported to use other software to assist in the compilation of part processes, and part process content completed by other systems (such as process models established using other software) can be integrated into the system to form a complete part process.

[0059] In an optional embodiment of the present application, the 3D model that needs to be processed can be opened in the PTC software, and the "model information extraction" function can be used to obtain the basic information such as the processing features, feature parameters, and materials of the 3D model. The "process feature identification" command is used to extract the processing feature type and processing-related dimensions and other information. The "process reasoning" command is used to identify the processing features; the appropriate processing technology is inferred in the process knowledge base, and the machine tools, fixtures, tools, processing parameters and other contents are planned in the process; then the "create tool path" command integrated with the CAM model is used to automatically create a manufacturing assembly model, and automatically create a tool path in the processing method library according to the processing method. The machining process planning calls the corresponding machining methods to create tool paths and completes the tool and machining parameter settings. It can determine whether the three-dimensional machine tools and fixtures need to be added to the manufacturing assembly model based on the machining situation; generate NC code through post-processing; the CAM programming module of the machining programming navigation system is closely linked to the early process planning, relying on the machining method library, tool library, machine tool library, and fixture library. At the same time, it can obtain the process, step, machining parameters and other information of the part or process model process planning, and automatically call the corresponding machining milling method in the machining method library based on the process information, assisting programmers to quickly generate machining tool paths, and finally generate NC code through the corresponding machine tool post-processing.

[0060] 4) A three-dimensional process model generation module 104, which is used to generate a blank and a process model based on the process information; wherein the blank and process model may include a blank model and a process model, wherein the blank model refers to an unprocessed model of the part to be processed in an initial state generated based on the process information; the process model refers to a process model for processing the part to be processed, which may be composed of different process steps.

[0061] 5) Navigation module 105, used to determine the simulation information NC program of the model to be processed according to the blank and process model, and generate a machining programming navigation file according to the simulation NC program. The machining programming navigation file is used to automatically execute machining programming by calling the simulation information NC program of the model to be processed based on the basic information of the part, processing feature information, process information, blank and process model, etc.

[0062] The machining programming navigation system provided by the embodiment of the present application at least includes: a model information extraction module, a part analysis module, a process planning module, a three-dimensional process model generation module and a navigation module, the model information extraction module extracts the basic part information of the part to be processed, the part analysis module determines the processing feature information of the part to be processed according to the basic part information, the process planning module determines the process information of the part to be processed according to the processing feature information, the three-dimensional process model generation module generates a blank and a process model according to the process information, the navigation module determines the simulation information NC program of the model to be processed according to the blank and the process model, and generates a machining programming navigation file according to the simulation NC program. The machining programming navigation file can be automatically generated by configuring the model information extraction module, the part analysis module, the process planning module, the three-dimensional process model generation module and the navigation module, and the machining programming navigation file is automatically executed through the machining programming navigation file, without excessive human intervention, reducing human errors and programming difficulty, and greatly improving the efficiency, accuracy and reliability of machining programming.

[0063] In an optional embodiment of the present application, the process information of the part to be processed can be determined based on the following process:

[0064] 3.1) Automatically create manufacturing assemblies based on processes

[0065] The manufacturing assembly model is the carrier for machining programming using the PTC software CAM module. Manually create a manufacturing NC assembly through the manufacturing module, then manually assemble the machining reference model, add the fixture model, and realize the manufacturing assembly. The machine tool, fixture, and machining zero position information required for machining are defined through the manufacturing assembly. When using the CAM programming module for machining programming, the machining process information of the programmed parts to be machined can be automatically obtained through the manufacturing assembly model. According to the settings of the machine tool and fixture information in the machining process, the CAM programming module automatically creates the manufacturing NC assembly model through the "Create Manufacturing Assembly" command.

[0066] 3.2) Create a machining coordinate system

[0067] The machining coordinate system is used as a reference for the position representation of the NC machining program. For example, in the graphical user interface, you can click "Coordinate System" on the toolbar to display the "Coordinate System" dialog box. There are many ways to create a machining coordinate system, which are not exhaustive here. This application uses the reference machining model reference coordinate system as an example to illustrate: for example, select "NC_ASM_DEF_CSYS" in the machining model in the "Model Tree" on the left side of the window, and the system fills "NC_ASM_DEF_CSYS" into the "Reference" list in the dialog box. Save the "X", "Y" and "Z" values ​​of the "Origin" page to be 0.0, indicating that the origin of the newly created machining coordinate system coincides with the origin of the reference coordinate. Zoom in and translate the graphics so that the blue new coordinate system graphic prompt in the graphics window is easy to observe. Select the "Direction" page in the dialog box, enter the rotation angle of each coordinate axis respectively, and use the correct direction of the newly created machining coordinate system. Enter the name of the machining coordinate system in the "Properties" page. Click "OK" and the system creates the machining coordinate system. The newly created coordinate system item can be observed in the "Model Tree".

[0068] 3.3) Create Operation

[0069] "Operation" is an abstract concept in PTC CAM, which is equivalent to the commonly said "process". The "operation" in this step is used to characterize the machining process. The "operation" defines the "machine tool" and "machining coordinate system" used in the compilation of the machining program. Different "machine tools" or "machining coordinate systems" are used for program compilation, and different "operations" are used accordingly. Each machining program in machining belongs to a certain operation. In actual application, you can click "Create Operation" in the PTCCAM toolbar, the "Create Operation" dialog box will appear, select "Processing Coordinate System", select "Machine Tool", set the safe moving plane coordinates in the "Z-axis" direction, and click "OK" to complete the operation creation. The newly created "operation" item can be observed through the model tree. Rename the operation, generally using the process number, such as P10, which means the 10th process. (This application can add a process number name input field in the dialog box, and the software will automatically fill in the operation name). For example, you can use PTC's "Operation" native function to check the detailed settings of the operation, assemble the machined parts as the machining programming object, set up the milling machine, call the corresponding fixture 3D model in the fixture library, set the zero position of the machined parts, and complete the basic preparation work based on process automation programming.

[0070] 3.4) Create a processing machine

[0071] Click the "CRRC Digital Manufacturing" page in the PTC CAM toolbar, select "Create Machine Tool", and the "Create Processing Machine Tool" dialog box will appear. The system will automatically read the list of all processing machine tools from the windchill system and display it in the "Processing Machine Tool List" interface. Select different processing machine tools to display some summary information of the corresponding machine tools. Select the "OK" button, the system will download the corresponding machine tool template and then create the machine tool. The newly created machine tool item can be observed in the "Model Tree". At the same time, the software system creates a built-in tool magazine system for the machine tool. This completes the creation of the processing machine tool.

[0072] In order to check the result of machine tool creation, this application uses PTC's native "Machine Tool" function for inspection. Right-click the machine tool item in the "Model Tree" and select "Edit" to open the PTC native machine tool function interface. You can check each setting item by item. Click the "Tool" page and select the "Tool..." button. The "Tool Settings" dialog box appears, where you can check the built-in tool magazine of the machine tool.

[0073] 3.5) Parts processing feature information extraction

[0074] Feature extraction and recognition are the premise of the entire system process, and the extracted processing feature information is the data basis for subsequent process reasoning and decision-making and even part CNC programming. Part processing feature information generally includes two parts: geometric information and non-geometric information, among which geometric information mainly includes shape and size, generally expressed in the structural dimensions of the three-dimensional model itself. Non-geometric information mainly includes dimensional tolerance, surface roughness, part material and other information, generally expressed in the form of annotations. In order to obtain complete and correct manufacturing feature information of parts, the entire feature extraction and recognition process of the embodiment of the present application can be roughly divided into two parts: extraction and recognition of part geometric information and non-geometric information, and combination of geometric features and corresponding non-geometric features.

[0075] Analyze the information that the process can understand from various information of the part model, and convert the design intent into process requirements. Take the minimum processing unit (processing feature) of the part model as the associated object, analyze the processing features of the part and their attributes and dimensions, identify the processing features and convert them into corresponding processing technology, and automatically extract the dimensions (design requirements) marked by the features into the attribute content of the process information.

[0076] Select the product design model to be processed in the system. The system obtains part name, code, material, product name, code and other information from the model. Based on this information, when inferring subsequent process attributes, the system can obtain relative processing technology from the resource library according to different product types, product structures and materials, to prepare for subsequent processing technology planning.

[0077] 3.6) Determination of processing technology

[0078] Process reasoning and decision-making is a very important module for the system to realize automation, and it is also a relatively complex and changeable module. When determining the processing flow, the embodiment of the present application not only considers the structural processability, but also considers information such as production batch, part material, enterprise manufacturing resources, and process resources. This makes process design a decision-making process with strong empiricism and many influencing factors. Due to problems such as variability and complexity, a method combining program automatic reasoning and human interaction is used to design the determination of the processing technology. First, the process resource knowledge base tool is used to automatically generate the processing technology of the part features, and then through human-computer interaction, the processing parameters and sequence are appropriately modified to obtain the correct process procedures. One exemplary process is as follows: Figure 4 shown.

[0079] After obtaining the manufacturing feature information of the part, the process reasoning and decision-making of the single processing feature are first carried out. This process is realized by calling the process rules in the feature processing technology knowledge base. The processing technology knowledge base saves some typical and commonly used historical processing technologies accumulated into the database, generates the corresponding process flow library, and then when designing parts with similar structures, the defined process flow and processing method can be selected from the process flow library. Only some feature parameters need to be changed to generate a new process information file. For example: first compare and match the identified processing feature information with the features in the process database, select the corresponding machine tool and processing method according to the feature type and shape in the processing feature information, and then select the processing type, feed rate, machine tool speed and other parameters according to the basic size, accuracy level and surface roughness requirements to complete the determination of the single feature processing technology. Since the storage order of the extracted part processing feature information is not completely consistent with the processing process route, after obtaining the processing technology of each feature, it is necessary to perform interactive process route design to obtain the correct part processing sequence, so as to determine the corresponding process information.

[0080] 3.7) Processing technology reasoning

[0081] According to the processing feature information, the processing reasoning function is used to infer the processing technology and processing allowance of the feature from the pre-configured knowledge base. According to the basic principles of process compilation and process resources, the processing technology of the feature is reorganized and arranged to form the processing procedure (route) of the part. According to the machine tool, feature, allowance, etc., the tool and processing parameters of each step are inferred from the knowledge base. The processing technology of the part is formed through the above three processes of feature processing procedure reasoning, part process arrangement, and step reasoning.

[0082] The embodiments of the present application support feature-oriented, knowledge-based process reasoning, which can adopt a knowledge-based intelligent process reasoning method, support process design based on typical processes and knowledge-based process decisions; based on process feature reasoning, users can sort, merge and reorganize processing features to quickly form a part process structure, greatly improving machining programming efficiency.

[0083] In the machining process, features, feature attributes, and feature processing methods are related. The embodiments of the present application can identify the geometric shape of features, and can also identify and utilize PMI information associated with features, and use these data for processing method reasoning. At the same time, based on feature recognition and feature parameter extraction, it is possible to perform processing method reasoning of process features to obtain processing methods of features, thereby giving full play to the value of design data. Processing method reasoning, based on a customizable reasoning process, is an open and maintainable knowledge base.

[0084] Refer to the knowledge definition in the knowledge base, which can be completed automatically by the computer or with human intervention, or manually input by the process personnel. The system can fully identify all the features of most parts and infer their processes, and most of the features of the remaining small part of the parts can also be identified and inferred. For a small number of part features or processes that cannot be identified and are not pre-defined in the system, users are supported to intervene in the reasoning process, or directly manually input feature processing methods to form part processes. For the process compilation of sporadic features of a small number of parts that are not covered by the system through configuration and development, users are supported to complete the compilation of part processes by manual addition. After completing the rapid compilation of the processing technology, the processing technology can be quickly queried and modified through the process manager to form a list of processing and manufacturing processes.

[0085] 3.8) Create plane milling

[0086] Taking the PTC CAM system as an example, you can click "Create Processing Program" on the toolbar, and the "Create Plane Milling" dialog box will appear. Click "Add" in the "Processing Geometry Elements" group, and the dialog box will be hidden to facilitate the selection of processing geometry elements. Select the plane geometry surface to be processed. Click "OK" on the right button of the screen or click the middle mouse button to complete the selection of processing geometry elements.

[0087] The process planning module will automatically read the process feature classification tree information from the windchill end and display it in the "Process Feature" group. Correctly select the process feature classification corresponding to the processing geometry element, click to obtain the "Processing Method", and the "Processing Method" list of this "Process Feature" classification will be automatically read from the windchill end, and the appropriate process solution can be selected.

[0088] Each "process plan" contains a corresponding work step list, in which you can quickly set the tool number, spindle speed and feed speed. The tool number list lists all the tools in the tool magazine of the machine tool used in this operation. After setting the appropriate parameters, click "OK", the system will automatically download the corresponding processing model from the windchill end and create a new processing program. The newly created processing program item can be displayed in the model tree.

[0089] After the above results are formed, you can select the generated tool path by clicking the corresponding button in the interface, and play the tool path animation through other operations, such as right-clicking and selecting "Play".

[0090] 3.9) Create hole machining program

[0091] Taking the PTC CAM system as an example, the hole machining program can be defined by selecting "Create hole machining program". Before creating the hole machining program, you need to define the drilling group. The drilling group can be defined by the "Drilling Group" button in the "Manufacturing" module of the CAM software. The drilling group can be selected by axis, diameter, radius, manual and other methods. Click "Create machining program" on the toolbar, and the "Hole machining program" dialog box will appear. Click "Add" in the "Machining geometry element" group. The dialog box is hidden to facilitate the selection of machining geometry elements. Select the plane geometry surface to be machined. Click "OK" on the right button of the screen or click the middle mouse button to complete the selection of machining geometry elements.

[0092] The process planning module will automatically read the process feature classification tree information from the windchill end and display it in the "process feature" group. Correctly select the process feature classification corresponding to the processing geometry element, click to obtain the "processing method", the system will read the "processing method" list of this "process feature" classification from the windchill end, and select the appropriate process solution.

[0093] Each "process plan" contains a corresponding work step list, in which you can quickly set the tool number, spindle speed and feed speed.

[0096] 3.10) Automatic generation of NC post-processing program

[0097] PTC converts the machining trajectory file into the post-processing required by the NC code program. Since there is no unified standard for CNC systems, different CNC system machine tools have different regulations on NC code functions.

Through the planned "output processing program" function, it automatically matches the processing machine tool post-processor to generate NC code files that conform to the machine tool processing format.
