Description

Technical Field

[0001] This invention relates to the field of three-dimensional laser cutting technology, specifically a method for maintaining a constant angle when cutting an inclined plane. Background Technology

[0002] In the field of control technology, when using bevel servo control in 3D laser cutting equipment, the sensor distance feedback obtained at the same cutting height varies depending on the angle, nozzle shape, and size. Therefore, in most machines, the inaccurate height feedback from the sensor during bevel cutting causes a misalignment between the laser beam focus and the actual cutting path, potentially resulting in damage to the cut workpiece. Summary of the Invention

[0003] Based on the shortcomings of the prior art described above, the purpose of this invention is to provide a method for maintaining a constant angle when cutting an inclined plane, so as to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for maintaining a constant angle during the cutting of an inclined plane, comprising:

[0005] S1: Position the cutting head to the fixed angle that needs to be compensated, measure the compensation angle corresponding to the height at each stage of the fixed angle through calibration, and enter the compensation angle in the table;

[0006] S2: Add the G87_P_Q instruction in the post-processor; detect contours with angles using the board model displayed in the CAM software and automatically generate the G87_P_Q45 instruction before the contours; automatically generate the G87_P_Q0 instruction before contours without angles.

[0007] S3: Import the instructions generated in step S2 into the CNC system and execute them. When cutting to a contour with an angle, select the corresponding compensation angle from the table measured in step S1 according to the height set by G87_P.

[0008] S4: Add the G87_P_Q instruction to the process subroutine; bind the G87 instruction to the process macro variable opened inside the system in the subroutine, and then call the subroutine before each contour through the G65P instruction, where P is the program number that determines the macro program;

[0009] S5: Add a configuration module to the process modification interface, allowing users to customize the follow-up height and angle parameters, and modify and save the set parameters in real time through the system interface.

[0010] The present invention is further configured such that step S1 includes:

[0011] Adjust the cutting head to the desired fixed compensation angle;

[0012] In EIA or other CNC programming systems, a series of fixed gap values ​​are set, ranging from 2mm to 16mm, with a total of 15 measurement points. If the gap is less than the minimum set value, no compensation is performed; if the gap is greater than the maximum set value, the cutting path will extend along the slope of the last straight line.

[0013] Using measuring tools or sensors, measure the cutting head height corresponding to each gap value. Through calibration, measure the compensation angle corresponding to the cutting head height at each stage of the fixed compensation angle, and enter the compensation angle into the table.

[0014] The present invention is further configured such that, in step S2, in the post-processing program, the instruction G87_P_Q is added, where P represents the height of the cutting head, Q represents the fixed compensation angle, and G87_P_Q45 indicates that during the cutting process, the cutting head will maintain a fixed compensation angle of 45 degrees.

[0015] Using the sheet metal model in CAM software, contours with angle changes are automatically detected. For each detected contour, a G87_P_Q command is automatically generated in front of the contour according to a preset fixed angle. If the contour does not have an angle change, a G87_P_Q0 command is automatically generated, indicating that no compensation is performed.

[0016] The invention is further configured to include a custom angle setting: the user can customize a fixed compensation angle according to actual needs. After customizing the fixed compensation angle, step S1 is re-executed to ensure that the new measurement data is correctly recorded.

[0017] The present invention is further configured to select the corresponding compensation angle from the table measured in step S1 based on the height currently set by G87_P, and the compensation logic is as follows: ×(y2-y1), where y is the actual following height, y1 is the reference height at 0 degrees, y2 is the measured height at 45 degrees, and x is the current bevel angle, where x1 is 0 degrees and x2 is 45 degrees.

[0018] The present invention is further configured such that step S4 includes:

[0019] The G87_P_Q instruction binding binds the G87 instruction to the process subroutine within the open process macro variables inside the system, allowing users to adjust the follow-up height and angle during the cutting process by modifying the process macro variables;

[0020] Subroutine calls: Before each contour, the process subroutine is called using the G65P instruction. The P parameter in the G65P instruction is used to determine the program number of the macro program.

[0021] The present invention is further configured such that step S5 includes:

[0022] The process modification interface will display the bound process in the CNC system. Users can customize and modify the follow-up height and angle through the process modification interface to meet different cutting needs.

[0023] Real-time monitoring and adjustment: During the cutting process, users can monitor the position and angle of the cutting head in real time and make adjustments according to the actual situation.

[0024] This invention provides a method for maintaining a constant angle during bevel cutting. The method comprises: S1: Positioning the cutting head to the required fixed angle; measuring the compensation angle corresponding to the height at each stage of the fixed angle using calibration; and inputting the compensation angle into a table; S2: Adding a G87_P_Q command in the post-processing; detecting contours with angles using the plate model displayed in the CAM software and automatically generating a G87_P_Q45 command before the contours; and automatically generating a G87_P_Q0 command before contours without angles; S3: Importing the commands generated in step S2 into the CNC system and executing them, and then cutting to... When an angled profile exists, the corresponding compensation angle is selected from the table measured in step S1 based on the height currently set by G87_P for compensation; S4: Add the G87_P_Q instruction to the process subroutine; bind the subroutine with the G87 instruction through the system's internal open process macro variable, and then call the subroutine before each profile using the G65P instruction, where P is the program number that determines the macro program; S5: Add a configuration module to the process modification interface, allowing users to customize the follow-up height and angle parameters, and modify and save the set parameters in real time through the system interface. The beneficial effects include:

[0025] 1. Improved Cutting Accuracy and Consistency: Step S1 precisely calibrates the cutting head angle at different heights and records the corresponding compensation angle in the compensation table. This ensures the cutting head maintains a constant angle at different heights, effectively avoiding laser beam focus shift caused by inaccurate height feedback from the sensor, thus improving cutting accuracy and workpiece consistency. Through the compensation calculation formula in step S3, the system can dynamically adjust the actual following height of the cutting head based on the current bevel angle, achieving precise angle compensation and ensuring the accuracy of the cutting path.

[0026] 2. Enhanced operational flexibility and convenience: Through step S2, the CAM software can automatically detect the angle contours in the sheet material model and generate corresponding G87_P_Q instructions, reducing the complexity and error rate of manual programming and improving operational efficiency. Steps S4 and S5 allow users to customize fixed compensation angles and follow-up parameters according to actual needs, flexibly adapting to different cutting tasks and improving the system's adaptability and user operation convenience;

[0027] 3. Ensuring operational safety and reliability: The compensation angle measurement and calculation in steps S1 and S3, combined with the instruction generation in step S2, ensure that every step of the cutting process is performed within a safe range, avoiding equipment damage and personal injury due to misoperation or system errors. The real-time monitoring and adjustment function in step S5 allows users to promptly detect and correct potential operational errors during the cutting process, further enhancing the system's safety and reliability.

Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0038] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0039] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0040] A method for maintaining a constant angle during the cutting of an inclined plane, such as... Figure 1 Shown, including:

[0041] S1: Position the cutting head to the fixed angle that needs to be compensated, measure the compensation angle corresponding to the height at each stage of the fixed angle through calibration, and enter the compensation angle in the table;

[0042] S2: Add the G87_P_Q instruction in the post-processor; detect contours with angles using the board model displayed in the CAM software and automatically generate the G87_P_Q45 instruction before the contours; automatically generate the G87_P_Q0 instruction before contours without angles.

[0043] S3: Import the instructions generated in step S2 into the CNC system and execute them. When cutting to a contour with an angle, select the corresponding compensation angle from the table measured in step S1 according to the height set by G87_P.

[0044] S4: Add the G87_P_Q instruction to the process subroutine; bind the G87 instruction to the process macro variable opened inside the system in the subroutine, and then call the subroutine before each contour through the G65P instruction, where P is the program number that determines the macro program;

[0045] S5: Add a configuration module to the process modification interface, allowing users to customize the follow-up height and angle parameters, and modify and save the set parameters in real time through the system interface.

[0046] Specifically, the cutting head is held at a fixed angle, then positioned to the desired fixed angle. The compensation values ​​required for the cutting head at different heights are then measured using a calibration method. Next, the G87_P_Q command (P: follow-up height; Q: follow-up angle) is added to the cutting program to set the follow-up height and angle. When the program cuts to an angled contour, G87Q_ is executed to maintain a constant follow-up angle. When cutting to a contour without an angle, G87Q_ is set to 0 degrees to switch angles. This improves cutting accuracy and avoids damage to the material.

[0047] The present invention is further configured as follows: Figure 2 and Figure 3 As shown, step S1 includes:

[0048] Adjust the cutting head to the desired fixed compensation angle; specifically, use mechanical control or CNC system to precisely adjust the cutting head to the predetermined fixed compensation angle to ensure that the cutting head is at a known and controllable angle in the initial state, providing a reference for subsequent height compensation measurement;

[0049] In EIA (Electrical Interface Adapter) or other CNC programming systems, a series of fixed gap values ​​are set, ranging from 2mm to 16mm, with a total of 15 measurement points. If the gap is less than the minimum set value, no compensation is performed; if the gap is greater than the maximum set value, the cutting path will extend along the slope of the last straight line. Specifically, in EIA or other CNC programming systems, a series of fixed gap values ​​are set, ranging from 2mm to 16mm, with a total of 15 measurement points. If the gap is less than the minimum set value (2mm), no compensation is performed; if the gap is greater than the maximum set value (16mm), the cutting path will extend along the slope of the last straight line to avoid compensation failure due to excessive gap.

[0050] Using measuring tools or sensors, measure the cutting head height corresponding to each gap value. Through calibration, determine the compensation angle corresponding to the cutting head height at each stage with a fixed compensation angle, and input the compensation angle into a table. Figure 4As shown. Specifically, using high-precision measuring tools or sensors, the cutting head height corresponding to each set gap value is measured at a fixed compensation angle. Through a calibration process, the compensation angle corresponding to each height is determined at the fixed compensation angle. The measured compensation angles are input and recorded in a compensation table to establish the correspondence between height and compensation angle, obtaining the angle compensation value required by the cutting head at different cutting heights. This ensures that the cutting head can be adjusted in real time according to the actual height during the cutting process, maintaining a constant cutting angle.

[0051] The present invention is further configured such that, in step S2, a G87_P_Q instruction is added to the post-processing program, where P represents the height of the cutting head, Q represents a fixed compensation angle, and G87_P_Q45 indicates that the cutting head will maintain a fixed compensation angle of 45 degrees during the cutting process; specifically, this instruction is used to dynamically adjust the angle of the cutting head during the cutting process to ensure that the cutting head can maintain a preset constant angle at different heights, thereby avoiding laser beam focus shift.

[0052] Using the sheet metal model in CAM software, contours with angular changes are automatically detected. For each detected contour, a G87_P_Q command is automatically generated before the contour based on a preset fixed angle. If the contour has no angular change, a G87_P_Q0 command is automatically generated, indicating no compensation. Specifically, the system automatically detects contours with angular changes in the 3D sheet metal model loaded in the CAM (Computer-Aided Manufacturing) software. For each detected contour with angular change, a G87_P_Q45 command is automatically generated before the contour based on a preset fixed compensation angle (e.g., 45 degrees); for contours without angular change, a G87_P_Q0 command is automatically generated, indicating no angle compensation at that contour. By precisely calibrating the cutting head angle at different heights and dynamically adjusting the compensation angle during cutting, the system ensures that the cutting head maintains a constant angle, avoiding laser beam focus shift and improving cutting accuracy and workpiece consistency.

[0053] The invention is further configured to include a custom angle setting: users can customize a fixed compensation angle according to actual needs. After customizing the fixed compensation angle, step S1 is re-executed to ensure that the new measurement data is correctly recorded. Specifically, a custom angle setting module is integrated into the process modification interface of the CNC system, providing an intuitive user interface that allows users to input or select the desired fixed compensation angle. Users input custom compensation angle values ​​through controls such as input boxes, drop-down menus, or sliders. The system verifies the input angle value in real time to ensure that it is within a reasonable range (e.g., 0 degrees to 90 degrees) to avoid setting invalid or dangerous angles. After the user confirms the custom compensation angle, the system prompts the user to confirm the modification to prevent accidental operation. Once the user confirms the new compensation angle, the system automatically re-executes step S1, including adjusting the cutting head to the new fixed compensation angle and measuring the new compensation angle at different heights through a calibration process. The measured new compensation angle data is recorded in the compensation table, replacing the previous data, to ensure that the latest compensation parameters are used in subsequent cutting processes.

[0054] The present invention is further configured to select the corresponding compensation angle from the table measured in step S1 based on the height currently set by G87_P, and the compensation logic is as follows: ×(y2-y1), where y is the actual following height, y1 is the reference height at 0 degrees, y2 is the measured height at 45 degrees, and x is the current bevel angle, x1 is 0 degrees, x2 is 45 degrees. Specifically, when the cutting head moves to a contour with different bevel angles, the system finds the corresponding compensation angle based on the current height and calculates the actual following height that needs to be adjusted using a formula, ensuring that the cutting head maintains a constant angle when cutting on an inclined plane. Through the precise calibration and compensation table recording in step S1, the system ensures that the cutting head maintains a constant angle at different heights, avoiding laser beam focus shift and significantly improving cutting accuracy and workpiece consistency. Using the compensation calculation formula, the following height of the cutting head is adjusted in real time according to the current bevel angle to ensure the accuracy of the cutting path and reduce cutting errors.

[0055] The present invention is further configured as follows: Figure 5 As shown, step S4 includes:

[0056] The G87_P_Q instruction binding, within the system's internal process macro variables, binds the G87 instruction to process subroutines, allowing users to adjust the follow-up height and angle during the cutting process by modifying the process macro variables. Specifically, within the system's internal process macro variables, the G87 instruction is bound to predefined process subroutines. When the G87 instruction is executed, it calls the corresponding subroutine to handle the adjustment of the follow-up height and angle. Through macro variables, the P parameter (representing the cutting head height) and Q parameter (representing the fixed compensation angle) in the G87 instruction are mapped to the corresponding functional modules in the subroutines, enabling the adjustment of the cutting head height and angle to be executed automatically based on the parameter values.

[0057] Subroutine calls, such as Figure 6 As shown, before each contour, the G65P command is used to call the process subroutine. The P parameter in the G65P command is used to determine the program number of the macro program. Specifically, before each cutting contour, the corresponding process subroutine is called using the G65P command. The P parameter is used to determine the specific macro program number to be called. When the system detects different contours during the cutting process, it automatically inserts the G65P command, calls the corresponding subroutine according to the characteristics of the contour, and performs height and angle compensation adjustments.

[0058] The present invention is further configured such that step S5 includes:

[0059] Process modification interface, such as Figure 7 As shown, the bound process will be displayed in the CNC system's process modification interface. Users can customize the follow-up height and angle through this interface to meet different cutting needs. Specifically, the process modification interface is designed as a user-friendly graphical user interface (GUI), including input boxes, drop-down menus, sliders, and other controls for easy parameter input and selection. The interface displays the currently bound process parameters, including the follow-up height and angle settings. Users can intuitively see the current configuration and make modifications.

[0060] Real-time monitoring and adjustment: During the cutting process, users can monitor the position and angle of the cutting head in real time and make adjustments as needed. Specifically, users can input or select the required follow-up height and angle parameters through the interface. The system provides a real-time verification function to ensure that the input parameters are within a reasonable range (e.g., height range of 2mm to 16mm, angle range of 0 degrees to 90 degrees). After the user modifies the parameters, the system automatically updates the compensation table and relevant instructions in the cutting program to ensure that the new parameters are correctly applied during the cutting process. The system allows users to save multiple configuration files, supporting quick switching between different cutting tasks and improving operational efficiency.
