DETAILED DESCRIPTION

[0019] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] It should be clear that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0023] In the early stage of the design of automotive interior and exterior parts, due to the conversion of different software formats and the quality of the connection of the modeling surface itself, the modeling surface input to the project often has problems such as being unable to be stitched, deformed and distorted. The existence of these problems requires engineers to invest a lot of time and energy to check the quality of the modeling surface and sew it one by one, which not only increases the workload, but also is inefficient and produces a lot of useless work.

[0024] Traditional CAD software, such as Siemens NX, provides some basic sheet processing tools, but these tools often require users to have high professional skills and are difficult to handle complex sheet problems, resulting in the inability to fully meet the high efficiency and high quality requirements for modeling surface processing in the design of automotive interior and exterior parts. Therefore, the present invention provides a sheet processing method for solving the above problems.

[0025] Please refer to Figure 1 , which is a flow chart of a method for processing a sheet provided by an embodiment of the present invention, comprising the following steps: Step S01, receiving an input film.

[0026] In this embodiment, the sheet body is the basic geometric entity constituting the three-dimensional model, which is composed of at least two modeling surfaces. The modeling surface is a three-dimensional model surface, which together defines the geometric shape and spatial positioning of the sheet body. The modeling surface can be a plane, a curved surface or a more complex geometric shape. In the design of automotive interior and exterior parts, the modeling surface is used to construct the external contour and internal structure of the product, which is crucial to the appearance and function of the final product.

[0027] By receiving these pieces, the system can further analyze, modify or optimize them. The quality of these modeling surfaces directly affects the manufacturing feasibility and final visual effect of the product. Therefore, ensuring the accuracy and integrity of these modeling surfaces is a key link in the design process. In this embodiment, the system can identify and process these modeling surfaces to improve design efficiency and product quality. In some embodiments, the process of receiving the input sheet and processing its modeling surface can be achieved by using professional 3D modeling software, such as Siemens NX or other computer-aided design (CAD) systems, to import or create sheet data. For example, in the software, these modeling surfaces can be generated and edited through a series of operations, such as stretching, rotating, sweeping, or Boolean operations. Each modeling surface needs to have its geometric properties precisely defined to ensure their accurate positioning in space and their relationship to each other. After completing the design of the modeling surface, the software will combine these surfaces into a sheet, which can be closed or open, depending on the specific needs of the design.

[0028] Step S02 , in response to the input abnormality detection instruction, perform abnormality detection on the sheet and output the abnormality detection result.

[0029] In this embodiment, upon receiving the user's instruction for abnormality detection in the CAD system, the system will automatically identify and analyze the integrity and quality of the sheet. For example, it may include checking whether the sheet has defects such as holes, cross-surfaces, deformation and distortion, which may affect the manufacturing and appearance of the product. Through advanced algorithms, such as the self-supervised feature adaptation (LSFA) framework, the system can capture tiny anomalies and avoid false alarms, thereby improving the accuracy of detection. After the detection is completed, the system will generate and output detailed abnormality detection results, which can be displayed in the form of graphics or lists, clearly pointing out the problem, and providing a basis for subsequent corrections and optimizations. This automated abnormality detection process not only improves design efficiency, but also ensures product quality and reduces the errors and time costs of manual inspections.

[0030] In some embodiments, the process of performing abnormality detection on the sheet and outputting the abnormality detection result mentioned in step S02 may specifically be: The system automatically executes preset anomaly detection algorithms, which may include geometric analysis, topology checking, surface continuity assessment, etc., to identify potential problems in the sheet, such as holes, intersecting surfaces, discontinuous surfaces, etc. The detection algorithm analyzes the geometric data of the sheet and identifies abnormal areas that do not meet the design specifications or engineering requirements. After the detection is completed, the system will output the anomaly detection results. For example, it includes visually highlighting the abnormal area on the 3D model, or generating a detailed report listing all detected anomalies and their location, type and severity. The entire process is automated, reducing the need for manual inspection, speeding up design iterations, and helping to discover and resolve problems in the early stages, avoiding greater costs during the production process.

[0031] Step S03, in response to the input processing instruction, the sheet is processed according to the abnormality detection result.

[0032] In this embodiment, after receiving the processing instruction issued by the user, the system will automatically perform a series of predefined operations to repair or optimize the sheet body based on the problems and abnormal detection results identified in the previous abnormal detection step. This process may include automatically filling holes, adjusting intersections, correcting deformation distortion, smoothing curved surfaces, etc., to ensure that the sheet body meets the design specifications and manufacturing requirements.

[0033] Through this automated process, users can save a lot of time on manually repairing models while improving the consistency and accuracy of repairs. For example, the system can use preset algorithms and machine learning techniques to determine the best repair strategy, thereby optimizing the geometric quality of the sheet while maintaining the design intent. This automated process not only improves design efficiency, but also helps ensure the quality of the final product and reduce potential problems in the manufacturing process.

[0034] In some embodiments, the process of processing the sheet according to the abnormality detection result mentioned in step S03 may specifically be: The system automatically applies preset repair strategies based on the anomaly detection results. For example, specific tools or commands can be used to fill holes, adjust intersections, correct deformations or smooth surfaces. During the repair process, the system can make further optimization adjustments to ensure that the repaired sheet not only solves the anomaly problem, but also maintains the design intent and manufacturing requirements. Furthermore, after the processing is completed, the system can perform anomaly detection again to verify the repair effect and ensure that the sheet meets the design and manufacturing standards. Finally, the system will feedback the processing results to the user, who can view the repaired sheet and make further manual adjustments or confirmations as needed. This automated processing flow not only improves design efficiency, but also helps to ensure the quality of the final product and reduce potential problems in the manufacturing process.

[0035] Based on the above technical solution, the sheet processing method provided by the embodiment of the present invention receives the input sheet; responds to the input abnormality detection instruction, performs abnormality detection on the sheet, and outputs the abnormality detection result; responds to the input processing instruction, processes the sheet according to the abnormality detection result. The present invention automatically performs detailed abnormality detection on the sheet in response to the abnormality detection instruction, and outputs detailed abnormality detection results. This automated detection process greatly reduces the workload of engineers' manual inspection and avoids the common inefficiency and errors in traditional methods. Further, after receiving the processing instruction, the sheet will be automatically processed accurately according to the results of the abnormality detection. Not only the stitching quality of the modeling surface and the accuracy of the modeling surface are improved, but also by reducing manual intervention, the useless work in the design process is reduced, thereby accelerating the product development cycle and improving the overall quality of the product. In addition, the automated processing process also helps to reduce the dependence on the professional skills of engineers, making the design work more standardized and efficient.

[0036] Please refer to Figure 2 ,for Figure 1 A flowchart of an actual performance of step S02 in a provided method for processing a sheet. In some embodiments, the abnormality detection of the sheet mentioned in step S02 and the output of the abnormality detection result may specifically include the following steps: Step S11, for each group of adjacent modeling surfaces in the sheet, calling a distance measurement command to measure the distance between the boundaries of the adjacent modeling surfaces.

[0037] In this embodiment, the actual distance between the boundaries of adjacent modeling surfaces is automatically calculated and compared by using a software measurement tool, such as the Measure Distance command in Siemens NX. The Measure Distance command can calculate the distance between two objects, the radius of an arc or a circle, the length of a curve, and the radius of a cylindrical surface. The basic principle of the Measure Distance command is to analyze the geometric properties of two objects, calculate the straight-line distance between the two objects, the actual length of the curve, and the radius of the arc, circle, and cylindrical surface, thereby achieving accurate dimensional measurement.

[0038] In some embodiments, the distance measurement command may be specifically implemented according to the NXOpen::Measurement::GetMinimumDistance function in the NX Open function library.

[0039] The purpose of this embodiment is to identify and locate abnormal shaped surfaces that affect product appearance, structural integrity or manufacturing feasibility, such as excessive gaps, overlapping or discontinuous boundaries. This automated calculation method provides data support for abnormal detection, which not only saves time and effort for manual inspection, but also improves the reliability of detection.

[0040] Step S12, determining whether the distance exceeds a preset tolerance parameter.

[0041] If yes, execute step S13.

[0042] In this embodiment, the preset tolerance parameters are determined based on design and manufacturing standards and represent the maximum acceptable distance deviation between the modeling surfaces. By comparing the measured distance value with the preset tolerance range, abnormal conditions beyond normal manufacturing and design tolerances can be identified, such as excessive gaps or unnecessary overlaps, which are to be avoided in the design of automotive interior and exterior parts.

[0043] If the distance exceeds the preset tolerance parameter, it indicates that there are potential quality problems or design defects in the sheet, such as the distance between the modeling surfaces exceeds the allowable range resulting in obvious holes, adjacent modeling surfaces overlap each other in certain areas, etc., and step S13 is executed at this time.

[0044] If the distance does not exceed the preset tolerance parameters, it proves that the modeling surface of the sheet is within the allowable error range of design and manufacturing, and has good geometric consistency and integrity. This means that the distance between the modeling surfaces is within the acceptable range, and there is no excessive gap or overlap between the modeling surfaces. At this point, it can also be confirmed that the sheet quality is qualified, and the current geometric parameters and measurement results are recorded for future reference and quality control.

[0045] The purpose of this judgment process is to ensure the quality and reliability of product design. Through automated anomaly detection, problems can be discovered in a timely manner, which helps reduce the errors and time costs of manual inspections, allowing the design team to focus more on innovation and optimized design rather than spending time on repetitive problem solving. In this way, companies can bring products to market faster while maintaining high quality standards.

[0046] In some embodiments, the following steps may be further included to modify the preset tolerance parameters: In response to the input modification command, the preset tolerance parameters are modified.

[0047] In this embodiment, an option to modify tolerance parameters may be provided through a user interface (UI). For example, a dialog box or menu may be included to allow the user to enter a new tolerance value or adjust it through a slider. The user may modify the preset tolerance parameters by clicking a "Modify Tolerance" button, selecting a "Modify Tolerance" menu option, or directly entering a new value in the dialog box.

[0048] Furthermore, the system can also verify the new tolerance value entered by the user, that is, check whether the new value is within a reasonable range or meets specific design standards. Once the new value is verified, the system will update the internally stored tolerance parameters to reflect the user's modification. After the tolerance parameters are updated, the system will re-check the sheet for anomalies to ensure that the detection results under the new parameters are accurate.

[0049] Step S13: Mark the modeling surface with a larger area among adjacent modeling surfaces as an abnormal modeling surface, and highlight the abnormal modeling surface.

[0050] This embodiment is used to quickly identify and locate problems. When the distance between the boundaries of adjacent modeling surfaces exceeds the preset tolerance parameter, the system automatically compares the areas of the adjacent modeling surfaces and marks the larger one as an abnormal modeling surface. The reason is that the larger modeling surface is more likely to be a key part of the design, and its abnormality may have a greater impact on the overall design. Subsequently, the abnormal modeling surface is highlighted so that the user can identify the problem area in a complex three-dimensional model.

[0051] The purpose of this embodiment is to improve the efficiency and effectiveness of anomaly detection. By highlighting, users can intuitively see which parts need further correction, which not only speeds up the problem identification, but also helps to focus resources and attention on the key areas that are most likely to affect product quality.

[0052] Based on the above technical solution, this embodiment can quickly identify abnormal areas that exceed the preset tolerance parameters by measuring the boundary distance of each group of adjacent modeling surfaces in the sheet. This significantly improves the speed and accuracy of abnormality detection, thereby reducing the need for manual inspection and potential errors. Automated detection not only improves production efficiency, but also ensures the consistency of product quality. In addition, highlighting abnormal modeling surfaces helps designers or engineers quickly locate the problem and take corrective measures in time. This intuitive feedback mechanism not only speeds up the design iteration, but also improves the efficiency of exception handling.

[0053] Please refer to Figure 3 ,for Figure 1 A flowchart of an actual performance of S03 in a method for processing a sheet body is provided. Based on the above embodiments, in some embodiments, the processing of the sheet body according to the abnormality detection result mentioned in step S03 may specifically include the following: Figure 3 Steps shown: Step S21, call the delete body command to delete all abnormal modeling surfaces.

[0054] In this embodiment, when the system identifies that there are modeling surfaces in the sheet body whose distance exceeds the preset tolerance, the delete body command will be triggered. The system deletes the abnormal modeling surface to eliminate defects in the sheet body model and create conditions for rebuilding and repairing the modeling surface. The delete body command can delete one or more bodies associatively. After executing the command and specifying the body to be deleted, a delete body feature will be generated. You can then click to suppress or delete the feature to undo the deletion operation, and you can choose to keep the specified body.

[0055] In some embodiments, the delete body command may be specifically implemented according to the NXOpen::Features::DeleteBodyBuilder function in the NX Open function library.

[0056] The purpose of this embodiment is to realize automatic repair processing of the sheet. By deleting the abnormal modeling surface, the geometric errors in the design can be eliminated. After deleting the abnormal surface, the system can construct a new repair modeling surface according to the boundary conditions, and then use the stitching command to merge the new modeling surface with the target modeling surface to form a new, defect-free sheet.

[0057] Step S22, calling the N-side surface command to create a repair modeling surface at the location where the abnormal modeling surface is deleted.

[0058] In this embodiment, when a modeling surface in a sheet is deleted due to quality issues, the N-side surface command is used to generate a new surface in the remaining space. The N-side surface command allows the system to define the shape and size of the new surface based on a set of boundary conditions or edge curves, thereby accurately filling the gaps created by the deletion operation.

[0059] This embodiment involves using the N-edge surface command to create a new repair modeling surface, which matches the surrounding modeling surfaces and meets the design specifications. The newly created repair modeling surface needs to maintain geometric continuity with the existing modeling surface, such as tangency or curvature continuity, to ensure smooth transition and overall beauty of the entire sheet.

[0060] This automated repair method not only improves design efficiency, but also helps ensure the quality of the final product and reduce potential problems in the manufacturing process. In this way, the integrity of the piece can be quickly restored while maintaining the accuracy and detail of the design.

[0061] In some embodiments, the N-sided surface command may be specifically implemented according to the NXOpen::Features::NSidedSurfaceBuilder function in the NX Open function library.

[0062] Step S23, calling the stitching command to stitch the repair modeling surface and the target modeling surface to obtain a new sheet.

[0063] In this embodiment, the repair modeling surface refers to a new surface created to replace the deleted abnormal modeling surface, and the target modeling surface is an existing surface adjacent to these abnormal modeling surfaces. The function of the stitch command is to geometrically connect the repair modeling surface with the target modeling surface to ensure that the boundary between them is smooth and continuous, thereby forming a unified, defect-free new sheet.

[0064] The purpose of this operation is to ensure that the newly created repaired modeling surface can be seamlessly integrated into the existing design to maintain the integrity and functionality of the design. Through the stitching process, the gaps or discontinuities caused by deleting abnormal modeling surfaces can be eliminated, while ensuring that the transition area between the new and old modeling surfaces meets the design requirements, such as smoothness, continuity, etc. In this way, the new sheet can meet the needs of manufacturing and assembly while maintaining the appearance and performance standards of the product. The stitching command provides an efficient way to repair and improve 3D models and is one of the indispensable tools in the design process.

[0065] In some embodiments, the stitching command may be specifically implemented according to the NXOpen::Features::SewBuilder function in the NX Open function library.

[0066] Based on the above technical solution, this embodiment improves the efficiency and accuracy of the design process. The automated processing steps reduce the need for manual operations, reduce the error rate, and ensure that the repaired modeling surface can meet the design specifications.

[0067] Based on the above embodiment, in some embodiments, after executing step S23 to call the stitching command to stitch the repair modeling surface and the target modeling surface to obtain a new sheet, the following steps may be further performed: Step S31, outputting a new sheet.

[0068] Step S32, in response to the input precision adjustment instruction, adjusting the suturing precision in the suturing command.

[0069] In this embodiment, if the user is not satisfied with the accuracy of the output new piece, the system allows the user to adjust the parameters of the stitching command to change the accuracy of the stitching operation. For example, the stitching accuracy may include adjusting the tightness of the surface matching, defining the geometric continuity level, etc., to ensure that the stitching between the newly created repair modeling surface and the target modeling surface meets the required design standards.

[0070] The purpose of this embodiment is to achieve precise control of the quality of sheet stitching to meet specific design and manufacturing requirements. By adjusting the stitching accuracy, the geometric matching of the modeling surface can be optimized, unnecessary material waste can be reduced, and the aesthetics and functionality of the product can be improved. In addition, precision adjustment also helps to ensure that the physical properties of the model, such as strength and durability, meet engineering specifications. This method provides flexibility, allowing users to personalize the stitching operation according to the specific needs of the product and the requirements of the manufacturing process.

[0071] In some embodiments, the method may further include: The stitching command is updated according to the adjusted stitching accuracy.

[0072] In this embodiment, by updating the stitching command, the system can ensure that every detail of the model meets the latest design specifications and manufacturing requirements, and realize automatic optimization of the model according to the parameters input by the user. This helps to improve the quality and performance of the final product and improve design efficiency.

[0073] Step S33, calling the adjusted stitching command to stitch the repaired modeling surface and the target modeling surface again.

[0074] In this embodiment, the stitching operation is performed again according to the new parameters after the user adjusts the stitching accuracy. By using the updated stitching command, the system will reprocess the joint between the repaired modeling surface and the target modeling surface according to the new accuracy parameters, such as higher geometric continuity requirements. The purpose is to ensure that the stitching between the repaired modeling surface and the original modeling surface meets the latest design standards and manufacturing requirements. The re-stitching process can correct the shortcomings that may exist in the initial stitching, such as geometric discontinuity, thereby improving the overall quality of the sheet.

[0075] Based on the above technical solution, the output of the new sheet in this embodiment allows the designer to evaluate and verify the results of the preliminary stitching to ensure that it meets the design and manufacturing standards. Secondly, in response to the precision adjustment instruction, the designer can fine-tune the stitching accuracy based on feedback or more stringent requirements, which increases the flexibility and adaptability of the design. Finally, calling the adjusted stitching command to re-stitch the process ensures the high quality and high precision of the new sheet, thereby improving the quality and performance of the final product. In addition, updating the stitching command according to the adjusted stitching accuracy ensures that the stitching operation is always based on the latest design parameters, which helps to reduce design errors and rework and improve design efficiency.
