Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, specifically to a method for drawing and cutting leak-proof holes on the side of T-shaped profile panels based on AM software. Background Technology

[0002] Profiles are classified into flat steel, angle steel, bulb flat steel, and T-sections according to their structural type. Profiles primarily provide structural support, load-bearing capacity, and improve construction efficiency. T-sections, as commonly used connectors between structures, are widely applied in shipbuilding. In ship design, there are two main modeling methods for T-sections: one is the plate frame modeling method, which is often used for lengths under 4 meters or for cases with large curvatures exceeding the capabilities of manufacturing equipment; the other is the profile modeling method, which is more widely used due to its advantages such as faster modeling speed and the ability to support automated T-section manufacturing lines.

[0003] Leak-stop holes (also known as flow-stop holes) are an important type of opening in ship structures. When steel reinforcement passes through watertight bulkheads such as oil and water tank dividers, leakage can occur because the fillet welds of the reinforcement are not fully penetrated. To prevent this leakage, leak-stop holes need to be made at the fillet welds on both sides of the reinforcement passing through the bulkhead, and then sealed by wrapping the corners or welding them completely, thus changing the non-penetrating structure into a fully penetrated structure. When the reinforcement passing through is a T-section, leak-stop holes also need to be made at the fillet welds where the web and face plates meet.

[0004] However, the existing technology still has the following problems and drawbacks. First, the limitations of AM software functionality prevent the direct design of panel-side leak-stop holes. Due to the limitations of AM software functionality, in the conventional mode, leak-stop holes are usually implemented using the NOTCH (type code Ra) opening method. However, NOTCH cannot be set on the panel side of T-profiles in AM software, resulting in the inability to provide design data on the panel side when a leak-stop hole needs to be opened through the watertight plate frame of the T-profile. AM design software is the core of the entire opening management process, capable of converting openings in the form of piping, electrical, ventilation, and other professional fields into actual openings required by the hull structure, but its NOTCH function has the aforementioned limitations. Second, manual operation leads to low efficiency and cost waste. Since the software cannot directly generate design data for panel-side leak-stop holes, designers can only manually indicate the opening position and opening information on the profile cutting drawing, and manufacturing personnel then manually cut the opening according to the manual instructions. This mode not only increases the workload of designers but also leads to a large amount of manual cutting operations in the manufacturing process, resulting in significant waste of time and costs. Third, the quality of manual cutting is difficult to guarantee. Manual cutting of leak-proof holes is inaccurate and inefficient, requiring extensive grinding after cutting. Furthermore, manual marking and cutting are prone to positional and dimensional errors, affecting the watertightness of the leak-proof holes and consequently impacting the safety of the ship's structure. Fourth, it hinders integrated design and manufacturing. A disconnect exists in the design-to-manufacturing process; the design phase cannot generate digital data for the leak-proof holes on the panel side, and the manufacturing phase cannot obtain corresponding CNC cutting instructions, making it difficult to move processes forward and automate production.

[0005] Therefore, there is an urgent need for a method that can automatically design, identify and convert leak-proof holes on the side of T-profile panels and directly generate CNC cutting instructions on the AM software platform, in order to solve the problems of missing design data, low efficiency of manual annotation, difficulty in guaranteeing the quality of manual cutting, and the disconnect between design and manufacturing processes caused by software function limitations in the existing technology. Summary of the Invention

[0006] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0007] This invention addresses the shortcomings of existing technologies where leak-proof holes on the side of T-profile panels cannot be directly designed in AM software and require manual annotation and cutting. It provides a method for designing and cutting leak-proof holes on the side of T-profile panels. This method involves adding a custom opening type to the AM software and using profile design software to automatically identify and convert the opening type, ultimately generating CNC cutting instructions, thus achieving full automation from design to manufacturing.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] As a first aspect of this application, the present invention discloses a method for drawing and cutting leak-proof holes on the side of a T-profile panel based on AM software, comprising the following steps:

[0010] Step S1: In the HOL management module of AM software, add a custom type code and establish a structured parameter mapping relationship between it and the leak-stop hole radius specification;

[0011] Step S2: In the 3D modeling environment of AM software, select the T-profile and call the custom type code added in step S1, and input the radius and position coordinate parameters of the leak-stop hole in the fillet weld area on the panel side of the T-profile.

[0012] Step S3: Using the profile separation function of AM software, the T-profile containing the panel side leak-proof hole design data is separated from the overall hull model to generate a GEN file containing leak-proof hole attribute information.

[0013] Step S4: The GEN file is converted into an open NOTCH of type FHa*b with cutability by using the profile section stress coupling deformation compensation algorithm, and a cutting data package is output.

[0014] Step S5: The profile design software's graphics generation engine generates a T-profile dimension drawing with complete panel side leak-proof hole positions and dimensions based on the cutting data package, and then converts it into a CNC cutting instruction set containing cutting paths and process parameters.

[0015] Step S6: Transmit the CNC cutting instruction set to the CNC cutting equipment, call the instruction execution module to parse segment by segment and drive the execution mechanism to automatically complete the cutting of the leak-proof hole on the side of the T-profile panel.

[0016] Preferably, a custom closed HOL opening type is added to the HOL management module of the AM software, and its type code is defined as FHa*b, where a is the radius specification parameter and b is the position or size correction coefficient;

[0017] In the AM software's 3D modeling environment, the fillet weld area on the panel side of the target T-profile is selected. By inputting the radius specification parameter a, the correction factor b, and the 3D coordinates of the opening center in the local coordinate system of the T-profile, the closed HOL opening is generated. Using the AM software's component separation function, the T-profile containing the closed HOL opening is separated from the overall hull model to generate a GEN file. The opening attribute list section of the GEN file retains the FHa*b type identifier of the opening and the specific values ​​of its radius specification parameter a and correction factor b.

[0025] Preferably, the opening type triplicate in step S4.1 includes a type identifier FH, a radius specification parameter a, and a correction coefficient b. The section stiffness matching degree is calculated using the opening type triplicate. Determining whether it falls within the matching threshold range determines whether the opening parameters meet the structural stiffness matching requirements. When the cross-sectional stiffness matching degree... When the radius specification parameter 'a' is below the lower limit, it is corrected upwards to the next level of standard specification. When the cross-sectional stiffness matches... If the value exceeds the upper limit, the conversion process is blocked and manual review is forced. After the verification is passed, the radius of the leak-stopping hole is obtained. Then, it is determined whether the center coordinates of the opening are located inside the geometric boundary of the T-profile panel. If the verification fails, an early warning mechanism is triggered to suspend the conversion.

[0035] Preferably, step S4.4 specifically includes:

[0036] Calculate the critical safety distance between the current leak-proof hole and any adjacent opening.

[0037] If the actual center distance Less than Then establish the interference penalty function. To minimize the interference penalty function The optimal offset vector for the target is iteratively solved along the negative gradient direction, and hard constraints are applied.

[0038] If the constraints cannot be met within 10 iterations, it is judged as a serious interference and a 3D position report is generated to request manual intervention.

[0039] Preferably, step S4.6 specifically includes:

[0040] Based on the transformed open NOTCH geometric data, an equivalent heat input and plate thickness-aperture joint response model was established, and the equivalent cutting power was fitted. ;

[0049] As a second aspect of this application, the present invention also discloses an electronic device, comprising:

[0050] At least one processor, and a memory communicatively connected to said at least one processor;

[0051] The memory stores instructions that can be executed by the at least one processor, which are executed by the at least one processor to enable the at least one processor to perform the steps of the above-described method for drawing and cutting the leak-proof hole on the side of the T-profile panel based on AM software.

[0052] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0053] This invention provides a method for drawing and cutting leak-stop holes on the panel side of T-profile profiles based on AM software. By customizing the FHa*b closed HOL opening type in AM software and leveraging the unrestricted position of HOL openings, this invention achieves for the first time the rapid addition of leak-stop holes at any position on the panel side of a T-profile profile using standardized parameters, completely solving the functional defect of traditional NOTCH which cannot be set on the panel side. With preset standardized parameter options such as FH15*1, FH10*1, and FH7*1, designers only need to select the type and input coordinates to complete the modeling, significantly improving operational efficiency and avoiding the tediousness and error risks of manual drawing. Furthermore, utilizing AM software's native support for component separation and the GEN file format, T-profile data containing complete design parameters for leak-stop holes is seamlessly and structurally transferred to the downstream processing design environment without disassembling the original type identifier, laying a standardized data foundation for subsequent automated conversion and manufacturing.

[0054] In the core transformation stage from design to manufacturing, this invention utilizes a profile cross-section stress coupling deformation compensation algorithm to perform multi-stage intelligent processing on the enclosed HOL, encompassing physical verification, geometric reconstruction, interference avoidance, and process matching: based on the cross-section stiffness matching degree... The threshold determination blocks unreasonable opening parameters at the source. Through dual compensation of the cross-sectional warpage coefficient and the heat-affected zone of the fillet weld, the opening position is precisely corrected. Based on the maximum circumferential stress fracture criterion, the contour topological shearing is driven, and the notch angle and root transition fillet radius are optimized. This ensures that the reconstructed open NOTCH meets fatigue strength requirements without generating stress concentration sharp corners. Simultaneously, the gradient descent method automatically avoids interference risks from adjacent openings. Building upon this, a correlation matching model of dimensions, materials, and processes is further established. Laser or plasma cutting parameters and defocusing amounts are differentiated for different hole diameter ranges, and the start and end points are scientifically placed in non-critical stress areas. Finally, this is packaged into an enhanced manufacturing data package with full-process verification and correction tags. This data package automatically generates dimensional drawings and CNC cutting instructions through profile design software and is directly transmitted to the cutting equipment for processing. This constructs a fully automated link from 3D modeling, data separation, intelligent conversion to CNC cutting, significantly shortening the design and manufacturing cycle, ensuring the stability and consistency of batch cutting quality, and forming a complete and traceable quality control chain in the form of process metadata tags.

[0067] Example

[0068] In this embodiment of the invention, a method for drawing and cutting leak-proof holes on the side of a T-profile panel based on AM software is disclosed, such as... Figures 1 to 7 As shown. Specifically, it includes the following steps:

[0069] Step S1: In the HOL management module of AM software, add a custom type code and establish a structured parameter mapping relationship between it and the leak-stop hole radius specification;

[0070] Step S2: In the 3D modeling environment of AM software, select the T-profile and call the custom type code added in step S1, and input the radius and position coordinate parameters of the leak-stop hole in the fillet weld area on the panel side of the T-profile.

[0071] Step S3: Using the profile separation function of AM software, the T-profile containing the panel side leak-proof hole design data is separated from the overall hull model to generate a GEN file containing leak-proof hole attribute information.

[0072] Step S4: The GEN file is converted into an open NOTCH of type FHa*b with cutability by using the profile section stress coupling deformation compensation algorithm, and a cutting data package is output.

[0073] Step S5: The profile design software's graphics generation engine generates a T-profile dimension drawing with complete panel side leak-proof hole positions and dimensions based on the cutting data package, and then converts it into a CNC cutting instruction set containing cutting paths and process parameters.

[0074] Step S6: Transmit the CNC cutting instruction set to the CNC cutting equipment, call the instruction execution module to parse segment by segment and drive the execution mechanism to automatically complete the cutting of the leak-proof hole on the side of the T-profile panel.

[0075] Regarding step S1, in the HOL management module of AM software, by adding custom type codes and establishing a structured parameter mapping relationship between them and the radius specifications of the leak-stop hole, a closed HOL opening configuration system facing the T-profile panel side is constructed, enabling designers to complete the leak-stop hole modeling at any specified location in the 3D modeling environment of AM software using standardized parameter input.

[0076] Specifically, refer to Figure 4 As shown, a new custom opening type is added to the HOL (Opening) management module of the AM software, with its type code defined as FHa*b. This type code adopts a structured naming convention, where "FH" is an abbreviation for "FluidHole," serving as a dedicated type identifier for the leak-stop hole. This identifier distinguishes it from other opening types such as ordinary process holes, drainage holes, and vent holes in the AM software's opening type database, ensuring unique identification during subsequent retrieval and conversion processes. 'a' represents the radius specification parameter of the leak-stop hole, in millimeters. Its value is determined according to the standard specification system for leak-stop holes in ship design specifications, including but not limited to commonly used specifications such as 7mm, 10mm, and 15mm. Designers can specify the required radius size of the leak-stop hole by modifying the value of the radius specification parameter 'a' in the parameter input interface of the AM software. 'b' represents the correction coefficient for the position or size of the leak-stop hole, used to fine-tune the precise position or contour details of the opening based on the standard radius specification, to adapt to different T-profile cross-sectional sizes and installation requirements at different penetration locations.

[0077] Furthermore, based on the commonly used radius specifications for leak-stop holes in ship design codes, this invention pre-configures the following standardized parameter types for designers to directly select: FH15*1 (corresponding to a leak-stop hole with a radius of 15mm), FH10*1 (corresponding to a leak-stop hole with a radius of 10mm), and FH7*1 (corresponding to a leak-stop hole with a radius of 7mm). The correction coefficient b, when set to a default value of 1, indicates no additional correction. Designers can also customize and input other correction coefficient b values ​​according to actual engineering needs to achieve fine-tuning. After completing the above configuration, designers only need to select the FHab type from the opening type drop-down menu in the AM software's opening function call interface. They then input or select the corresponding parameter values ​​according to the design drawing requirements, including the radius specification, the X / Y / Z three-dimensional coordinates of the opening center in the T-profile's local coordinate system, and the opening orientation. This allows for precise addition of leak-stop hole designs at any specified location on the T-profile, including panel side areas that cannot be set using the conventional NOTCH method.

[0078] In this invention, the FHab opening type is defined as a closed HOL opening in AM software, meaning its geometric profile is recorded as a closed ring-shaped topology in the internal data structure of AM software. The opening shape is semi-circular, arc-shaped, or U-shaped, and the opening parameters fully record all essential information such as the design radius of the leak-proof hole, the coordinates of the opening center position, the opening direction, and the opening angle. This closed HOL opening definition method cleverly circumvents the limitation that NOTCH cannot be set on the panel side in AM software by utilizing the technical characteristic of AM software that allows no positional restrictions on HOL type openings. This provides a complete and standardized original data foundation for subsequent type conversion and geometric reconstruction using profile design software.

[0079] Regarding step S2, in the 3D modeling environment of the AM software, select the T-profile component and call the custom type code added in step S1. Then, input the radius and position coordinates of the leak-proof hole in the fillet weld area on the T-profile panel side. (Refer to...) Figure 2 and Figure 5 In the 3D modeling environment of AM software, the T-shaped profile that needs to have a leak-stopping hole is first selected from the hull structure model. This T-shaped profile is usually used as a skeleton component that penetrates the watertight bulkhead or liquid tank bulkhead, and the fillet weld area formed by the intersection of its panel side and web side is the key part for opening the leak-stopping hole.

[0080] Specifically, after locating the target T-section in the AM software's modeling interface by clicking or searching, the designer uses the AM software's opening modeling tool and selects the FHa*b type configured in step S1 from the opening type drop-down menu. Then, based on the leak-stop hole location information marked on the ship design drawings, the designer determines the precise location of the opening center point on the T-section panel side. After determining the location, the designer fills in the key design parameters of the leak-stop hole in the parameter input interface, including radius specification parameter a, correction factor b, the three-dimensional coordinates of the opening center in the T-section's local coordinate system, and the opening angle. Radius specification parameter a can be selected from standard values ​​such as 7mm, 10mm, and 15mm, or a custom value can be entered based on the design drawings. The correction factor b is usually set to 1 by default; other values ​​can be entered if a slight offset adjustment of the opening center is required. The three-dimensional coordinates of the opening center in the T-section's local coordinate system are then entered. That is, the X-axis is along the length of the T-profile, the Y-axis is along the width of the panel, and the Z-axis is along the height of the web. The orientation angle of the opening is determined based on the installation direction of the T-profile when it penetrates the bulkhead.

[0081] After inputting the above parameters, the AM software generates a closed HOL opening at a specified location on the panel side of the T-profile according to the internal definition of the FHa*b type. This opening is stored in the AM software's model database with its geometric contour data (including complete information such as center coordinates, radius, and opening direction) and type identifier FHa*b, and is associated with the T-profile component, saved as a sub-attribute of the T-profile along with the model. Thus, by simply inputting standardized parameters, digital modeling of the leak-stop hole can be completed in the panel side area where NOTCH could not be set previously. The entire operation requires no manual drawing or additional annotation, fundamentally solving the functional defect in AM software that the NOTCH type cannot be applied to the panel side. This provides accurate and complete original design data for subsequent steps of automated identification, conversion, and cutting instruction generation using profile design software.

[0082] Regarding step S3, the T-section containing the panel-side leak-stop hole design data is separated from the overall hull model using the Profile Separation function in AM software, generating a GEN file containing leak-stop hole attribute information. After completing the modeling design of the T-section panel-side leak-stop hole in AM software, the designer calls the built-in Profile Separation module in AM software to perform the profile separation operation on the T-section that already contains FHa*b type leak-stop hole data. This profile separation function is a standard tool module provided by AM software for the production design stage. Its core function is to independently extract specific types of components from the overall hull structural model according to manufacturing units and management granularity, forming a single component data file that can be recognized by the subsequent processing design system.

[0083] In practice, designers select or individually choose the target T-profiles that have been modeled in the AM software's model browsing view, and initiate the component separation command. The AM software then automatically executes the data decomposition process. First, it traverses the tree structure nodes of the target T-profile to extract its geometric data, including the cross-sectional contours, lengths, and end shapes of the faceplate and web. Simultaneously, it retrieves all sub-attribute data associated with the T-profile, including all design parameters for the panel-side leak-proof holes added in step S2 using the FHa*b type, including the hole type code FHa*b, the specific values ​​of the radius specification parameter a and correction factor b, the precise three-dimensional coordinates of the hole center in the T-profile's local coordinate system, and the hole opening orientation angle. All the above data is integrated by the AM software and output in GEN file format to the specified project data directory. The GEN file is a standardized component description file generated by AM software for the manufacturing stage. It uses a structured text recording method to record the complete component information of the T-profile in a predetermined data segment, including the basic component attribute segment (component number, profile specification model, material grade, length dimension, etc.), the cross-sectional geometry data segment (cross-sectional shape parameters of the face plate and web plate, relative positional relationship, etc.), and the opening attribute list segment (recording all the opening information on the T-profile in sequence, with each opening stored as an independent data entry, including opening type identifier, geometric dimension parameters, positioning coordinates and spatial orientation data).

[0084] In this process, the panel-side leak-proof hole added in step S2 strictly maintains its original hole type FHa*b record format in its corresponding data entry. That is, "FHa*b" and its accompanying radius specification parameter a and correction coefficient b are explicitly written in the hole type field of the GEN file, without any prior type conversion or format modification. This design of retaining the original type identifier ensures that the leak-proof hole can be accurately identified as the panel-side leak-proof hole type specifically defined by this invention when read by the profile design software in subsequent steps, thereby triggering the corresponding automatic conversion process. At the same time, by using the GEN file natively supported by AM software as the data transmission medium, this invention achieves lossless and structured transmission of panel-side leak-proof hole design data from the 3D modeling environment to the profile processing design environment without changing the existing data architecture of AM software, providing a standardized data input interface for intelligent identification and conversion in step S4.

[0085] Regarding step S4, the GEN file is processed using a profile cross-section stress coupling deformation compensation algorithm. This process involves intelligent transformation of the FHa*b type leak-proof hole, based on geometric feature recognition, physical and mechanical verification, and dynamic topology reconstruction. The result is a Ra type open NOTCH with cutability, outputting a cutting data package containing complete geometric information and process parameters. The process also includes the following steps:

[0086] Step S4.1: Perform lexical analysis and syntax verification on the FHa*b opening type identifier in the GEN file to extract the opening type triplet, calculate the cross-sectional stiffness in combination with the geometric dimension parameters and determine whether it meets the structural stiffness matching requirements, and at the same time determine whether the center coordinates of the opening are located inside the geometric boundary on the side of the T-profile panel.

[0087] Step S4.2: Read the nominal position of the leak-proof hole, retrieve the complete geometric dimension parameters of the T-profile, extract the moment of inertia of the section, and calculate the section warping coefficient. Then, the offset compensation amount is calculated. And correct the nominal center coordinates to replace the original position data;

[0088] Step S4.3: Dynamically calculate the actual notch opening angle and root transition fillet radius based on the maximum circumferential stress fracture criterion, and simultaneously update the geometric properties of the opening from closed area filling to open contour path, and define the converted open NOTCH type code as Ra.

[0089] Step S4.4: Construct the critical safety distance formula and establish a nonlinear interference penalty function. Use the gradient descent method to iteratively solve the optimal offset vector to implement directional avoidance of interference risk. If the iteration converges, output the final position to the process matching stage. If the offset exceeds the limit, feed back to S4.2 and S4.3 to trigger secondary correction.

[0090] Step S4.5: Collect the original leak-stopping hole parameters, the corrected final center coordinates and offset records, the actual notch opening angle, the root transition fillet radius and interference processing records, and package them together with the reconstructed contour coordinates into a process metadata tag set and write it into the graphic data.

[0091] Step S4.6: Dynamically fit the cutting power according to the equivalent power equation and differentiate the gas pressure and decoking amount. Set the arc starting point and arc ending point at a specific distance from the transition fillet. Combine the optimized process parameters and metadata tags and encapsulate them into a cutting data package for output.

[0092] In step S4.1, lexical analysis and syntax verification are performed on the FHa*b opening data in the GEN file to extract the semantic structure of the triplet consisting of the type identifier FH, the radius specification parameter a, and the position correction coefficient b. Simultaneously, the panel thickness of the T-profile is extracted from the cross-sectional geometry data segment of the GEN file. Panel width and web height The cross-sectional stiffness matching degree is determined as follows: ,in For panel thickness, For panel width, This is the height of the web. (Based on judgment...) Whether the value falls within the reasonable threshold range of 0.012 to 0.085 determines whether the opening parameters meet the structural stiffness matching requirements. If the size of the leak-stopping hole is determined to be too small when it is below the lower limit, the radius specification parameter a is corrected upwards to the next level specification in the predefined standard specification series in step S1 to prevent crack propagation; when If the opening size exceeds the upper limit, it is determined that the excessive size may weaken the load-bearing capacity, thus halting the conversion process and requiring manual review. After successful verification, the final determined leak-proof hole radius is recorded as follows: Simultaneously, it verifies whether the center coordinates of the opening are located inside the geometric boundary of the T-profile panel side. If any verification fails, an early warning mechanism is triggered to suspend the conversion, thus preventing structural failures or cutting defects caused by parameter errors from the source.

[0093] In step S4.2, after reading the nominal location of the leak-stop hole, the complete geometric dimension parameters of the T-profile in the cross-sectional geometry data segment of the GEN file are retrieved, including the panel width. Web height Panel thickness Web thickness The moment of inertia of the section is calculated based on the combined section translation axis theorem using the above geometric parameters. (in the direction of the web) and (Panel direction), then calculate the cross-sectional warping coefficient. The formula for calculating the translation axis of the combined section here is a common formula in existing technology, so it will not be elaborated further. Based on this, the lateral offset compensation amount of the panel is calculated. Correct the nominal center coordinates along the width of the panel towards the web side. .in The corrected radius of the leak-proof hole. For web thickness, For web height, the correction factor b defaults to 1. When the value exceeds 0.25, higher-order terms are further introduced. Simultaneously calculate the width of the heat-affected zone of the fillet weld. And determine the minimum distance between the center of the opening and the edge of the panel. Does it meet the safety requirements? If so... With a safety margin of +3mm, the center will automatically shift inward. To mitigate the risk of edge cracking. In addition, based on the structural logic of the T-shaped profile penetrating the watertight bulkhead, the opening orientation of the leak-proof hole was adjusted so that it faced away from the bulkhead centerline, ensuring that the actual cutting position maintained the optimal relative relationship with the stress neutral surface under design conditions.

[0094] In step S4.3, a contour topology shearing algorithm is performed on the FHa*b closed contour to determine the actual notch opening angle and root transition fillet radius based on the maximum circumferential stress fracture criterion. A stress concentration factor fitting function is then introduced. And combined with the structural allowable upper limit By reverse calculation of the maximum permissible notch angle, the actual notch opening angle can be determined. Simultaneously, a nonlinear correlation was constructed between the root transition fillet radius and the plate thickness, opening radius, and yield strength. .in This represents the actual yield strength of the steel, and... Apply Boundary constraints are applied. NURBS curve fitting is used to generate transition fillets that smoothly transition with straight and circular arc segments at the shear opening of the contour. At this point, the geometric properties of the opening are updated from the original closed area filling to an open contour path, ensuring that the transformed leak-proof hole contour does not produce stress concentration sharp corners and meets fatigue strength requirements, such as... Figure 3 As shown. Meanwhile, the type code for the transformed open NOTCH is defined as Ra, to distinguish it from the original closed FHa*b type, for subsequent dimensioning annotation and data tracing.

[0095] In step S4.4, after the conversion is completed, the engine starts the spatial interference diagnosis subroutine to calculate the critical safety distance between the current leak-stopping hole and any adjacent opening. ,in The radius of the leak-stopping hole after conversion. This is the equivalent radius of adjacent openings extracted from the opening attribute list segment of the GEN file. If the actual center distance... Then establish the interference penalty function. To minimize the interference penalty function The optimal offset vector is iteratively solved along the negative gradient direction for the target, with the iteration step size set to [value missing]. and apply hard constraints If the constraints cannot be met within 10 iterations, it is considered a serious interference, and a 3D positioning report is generated to request manual intervention to prevent through-holes or structural breakage during on-site cutting. If the offset exceeds the limit, it will be fed back to steps S4.2 and S4.3 for secondary correction.

[0096] In step S4.5, all profile graphic data after adaptive correction and topology reconstruction is output. This data includes the leak-proof hole contour coordinates converted to Ra type, as well as a process metadata tag set. The process metadata tag set contains the original FH parameter values ​​from the GEN file, the corrected actual center coordinates from step S4.2, and... Offset record, actual notch opening angle in step S4.3 and root transition fillet radius The interference processing records and offset vectors from step S4.4 are also included. These labels, along with the reconstructed Ra-type open NOTCH profile coordinate data, are written into the database to form a complete design change traceability chain.

[0097] In step S4.6, an equivalent heat input and plate thickness-aperture joint response model is established based on the converted open NOTCH geometric data, according to... Dynamically fitted equivalent cutting power, where To match the cutting speed from the process parameter library, The material's overall cutting coefficient is mapped from the material grade in the GEN file (450 for ordinary marine grade A steel, 620 for high-strength steel DH36). This is for small radii ( Leak-proof holes, with cutting speed set according to high-precision laser cutting parameters. Defocus amount Matching gas pressure High-precision laser cutting parameters at MPa and positive defocusing amount +1.5mm; for large radius ( Leak-stop hole, matching plasma cutting parameters to set cutting speed. Defocus amount Matching gas pressure The plasma cutting parameters and zero defocusing amount are measured in MPa. and This is to determine the standard cutting speed from the process parameter library, matching the plate thickness and material. Simultaneously, the cutting start point is... Set at the starting point of the transition fillet at the root of the notch Point of intersection, arc termination Set on the other side of the gap The starting and ending arc directions should be perpendicular to the direction of the maximum principal stress to avoid the defect being located in the stress concentration peak area.

[0098] The final result will be all data after physical compensation positioning, dynamic topology shearing, nonlinear interference avoidance, and differentiated process matching. This data will be packaged as an accessory. Verification results Offset recording and cutting power Cutting speed Gas pressure Defocus amount The segmented data packet, encapsulated as a physical layer label, provides a fully parameterized data base for step S5, which includes both geometric and process information.

[0099] Regarding step S5, the profile design software's graphics generation engine generates a T-profile dimensional drawing with complete panel-side leak-stop hole positions and dimensions based on the cutting data package. Simultaneously, the built-in post-processing module converts the open NOTCH contour trajectory into a CNC cutting instruction set containing cutting paths and process parameters. It should be understood that the aforementioned profile design software can be integrated with AM software (i.e., AM software includes profile separation, data conversion, drawing generation, and instruction compilation functions), or it can be a separate, professional profile processing design platform, as long as it can receive and parse the GEN file containing FHa*b type leak-stop hole information output in step S3.

[0100] The profile design software first reads the cutting data package output in step S4, which contains the main outline of the T-profile and all geometric data of the adaptively corrected panel-side leak-proof holes (Ra type open NOTCH profile coordinate sequence, actual opening angle). Root transition fillet radius (and corrected center coordinates). Based on this, the graphics generation engine automatically lays out and generates T-profile dimensional drawings according to the company's standardized drawing format, usually presented as three views or unfolded views. In the panel side view, the type code Ra of the leak-stop hole and the radius of the leak-stop hole are marked with crosshair positioning lines and leader lines. Actual notch opening angle The dimensions relative to the bulkhead ensure accurate acceptance by on-site inspectors based on the drawings. After the dimensional drawing is generated, the post-processing module converts the contour data into machine instructions (G-code or dedicated instruction set) recognizable by CNC cutting equipment. First, the contour trajectory of the reconstructed open NOTCH is extracted and adaptively discretized into a coordinate node sequence according to the curvature change. Then, the differentiated process parameters (cutting power) output from step S4 are bound to it. ,speed Gas pressure and defocus amount This is then compiled into cutting code. Taking advantage of the open NOTCH feature, an arc-initiating point is generated from outside the edge of the board material. (Starting point of the transition fillet at the root of the notch) (at the point) and from the point of arc termination (distance from the end of the transition fillet) The special lead-out trajectory (from the point of origin) ensures that the unstable start and end arc segments are completed in non-critical areas. Simultaneously, cutting compensation logic is applied, using equidistant offset compensation (0.1mm~0.3mm) on the contour based on the sheet thickness to ensure the finished product dimensions match the theoretical values. Finally, all path data, process parameters, and auxiliary instructions are integrated into a complete cutting instruction file, including a header (equipment identification code, material and thickness identifier), a process parameter setting section (global parameters), a trajectory execution section (X / Y / Z axis movement instructions and coordinate node sequences, including start and end arc lifting and lowering control), and a tail section (reset instructions). This file can be directly transferred to the profile CNC cutting equipment for execution without manual editing, achieving automated data flow from the 3D model to CNC instructions.

[0101] Regarding step S6, the CNC cutting instruction set is transmitted to the CNC cutting equipment, and the instruction execution module is called to parse the instruction segment by segment and drive the execution mechanism to automatically complete the cutting of the leak-proof hole on the side of the T-profile panel.

[0102] The manufacturing department loads the cutting instruction file into the CNC control system of the CNC cutting equipment via a workshop data network (such as a DNC system) or mobile storage media. After the operator retrieves the corresponding file on the equipment interface, the system automatically verifies the consistency between the workpiece material and thickness markings and the currently clamped base material. Once confirmed, the automatic cutting program is started. The CNC controller reads the trajectory instructions segment by segment, generates continuous motion instructions for each servo axis through internal interpolation calculations, and simultaneously calls the corresponding cutting power, gas pressure, and defocusing amount according to the bound process parameters. The cutting head first moves to the arc starting point at idle speed. (Located in the safe area outside the side edge of the panel), cut into the starting point of the leak-proof hole outline along the lead-in line, and then complete the full outline cutting of the arc segment and the straight line segment in sequence along the reconstructed open NOTCH outline coordinate sequence, and finally cut from the arc termination point. Cut along the lead-in line to the outside of the sheet metal to complete the cutting cycle of a single leak-proof hole. Multiple leak-proof holes on the same T-profile are automatically completed sequentially according to the instructions. For the open-notch geometry, the cutting trajectories of the lead-in and lead-out lines are pre-optimized by the post-processing module to ensure that unstable cutting areas at the beginning and end of the arc are all outside the functional contour of the leak-proof hole. After cutting, the contour surface is smooth and free of sharp corners and burrs, requiring only minimal grinding to meet marine inspection standards. The entire cutting process requires no manual marking or operation, achieving fully automated manufacturing from design data to finished parts, effectively reducing labor costs and ensuring the stability of batch cutting quality.
