Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, and in particular to an online teaching method and system suitable for laser cutting. Background Art

[0002] Laser cutting technology is widely used in the precision machining of materials such as metals, plastics, and ceramics. With the advancement of industrial automation, traditional cutting methods are gradually evolving towards intelligent and automated methods. To improve machining accuracy and efficiency, laser cutting systems typically rely on G-code (CNC code) for control. G-code is generated by the cutting program and is used to guide the motion of the laser cutting head.

[0003] During the actual cutting process, factors such as blank placement errors, material deformation, and machine accuracy can lead to deviations between the theoretical cutting point and the actual cutting position. Traditional laser cutting systems often require manual intervention to correct these deviations. However, traditional methods often cannot make real-time adjustments or require manual reprogramming of the cutting program, resulting in low efficiency and prone to errors.

[0004] The present invention introduces a G-code cutting file generated based on a theoretical model of the blank, and combines it with a real-time feedback mechanism and automated adjustment means to provide an online teaching method and system, which can automatically pause, locate and modify deviations during the actual cutting process to ensure the accuracy of the cutting path, while simplifying the operation process and improving cutting efficiency.

[0053] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the embodiments of the present 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 the embodiments of the present invention.

[0054] Example 1

[0055] An online teaching method suitable for laser cutting, such as Figure 1 、 2 Shown, including:

[0056] S1: Run the G-code cutting file generated based on the theoretical model of the blank, pause and record the line number at the deviation between the theoretical cutting point and the actual cutting position, select the preset operation mode for adjustment according to the displayed data, and after the adjustment is completed, the edited data will overwrite the original file and reload it. The preset operation mode includes manually moving the cutting head and recording the real-time coordinates and modifying the positioning / interpolation instructions or macro program call parameters in the G-code;

[0057] Or S2: Enter the cutting program and set the cutting parameters in the software editing interface. The cutting parameters include cutting speed and process type, and move the cutting head to the specified position to execute the cutting instructions. By inserting relevant instructions and macro programs in the display list, complete the definition and editing of each cutting contour and generate a G-code program;

[0058] Specifically, the G-code cutting file generated based on the theoretical model of the blank is run, and the G-code cutting file is automatically generated according to the pre-set theoretical model of the blank, including material shape, size and cutting path, etc. The G-code file contains instructions to control the cutting head to move along a specific path during the work process; during the cutting process, when the deviation between the theoretical cutting point and the actual cutting position exceeds the set processing accuracy range, the processing process is automatically paused. The pause operation helps to adjust the cutting path in time to avoid error accumulation or inaccurate cutting; the current G-code file line number when the deviation occurs is recorded, so that it is convenient to return to the position where the deviation occurs for adjustment in subsequent operations to ensure the accuracy of the modification; based on the recorded data, one of the two preset operation methods can be selected to adjust the deviation, manually move the cutting head and record the real-time coordinates and modify the positioning / interpolation instructions or macro program call parameters in the G-code; after the adjustment is completed, the relevant line data in the original G-code file will be overwritten and reset The newly loaded updated file ensures the accuracy of the cutting program and enables the modifications to take effect immediately; enter the cutting program through the software interface, set the cutting parameters, including cutting speed and process type, and control the movement of the cutting head; enter the detailed cutting program in the software interface, including specifying the cutting speed and process type parameters, which will affect the speed, accuracy and quality of the cutting process; specify the starting position of the cutting head in the software interface, and instruct the cutting head to move to the specified position and start the cutting operation by entering the cutting instruction; provide a display list, in which different instructions and macro programs can be inserted; by gradually inserting instructions in the display list, complete the definition of the cutting contour, which may include multiple cutting paths, and the start and end points, cutting method and other information of each path can be adjusted; after the contour definition is completed, a G-code program will be automatically generated, which includes all the movement instructions of the cutting head to ensure the correctness of the cutting path and cutting parameters.

[0059] The present invention is further configured such that the S1 operation process is as follows Figure 3 Specifically shown include:

[0060] S11: Run the G-code cutting file generated based on the blank theoretical model. Specifically, a G-code file is automatically generated based on the blank theoretical model. The blank theoretical model includes the size, shape and cutting path of the material. The file contains all the cutting instructions that need to be executed. These instructions will control the motion path and cutting parameters of the laser cutting machine to ensure that the processing can be carried out according to the predetermined plan.

[0061] S12: When the deviation between the theoretical cutting point and the actual cutting position exceeds a threshold, the processing is paused and the current line number is recorded. Specifically, during the processing, the deviation between the theoretical cutting point and the actual cutting position is monitored. When the deviation exceeds the set allowable error threshold, the cutting operation is automatically paused and the G code line number when the deviation occurs is recorded for subsequent positioning and adjustment.

[0062] S13: Read the file and locate the record line and display the current line data; specifically, when the cutting is paused, read and locate the recorded G code line number, and display the data of the line on the display interface. The data includes positioning instructions / interpolation instructions or encapsulated macro program call instructions, which provides clear reference information for subsequent adjustments. The display interface is as follows: Figure 5 As shown;

[0063] S14: Modify the positioning / interpolation instruction data by manually inputting an offset or repositioning the cutting head. Specifically, when there is a deviation in the positioning or interpolation data, the user can choose to manually input an offset or reposition the cutting head to make corrections.

[0064] S15: Modifying the calling parameters of the encapsulated processing graphic macro program calling instruction; specifically, in certain cases, the cutting path is completed by calling the encapsulated processing graphic macro program. The macro program is usually a predefined set of cutting instructions that can simplify the generation of complex paths. If deviations occur, the calling parameters of the macro program can be modified to adjust the path or other processing parameters to meet actual processing needs;

[0065] S16: Confirm the modification and overwrite the original file data; after the user completes the adjustment, the system will confirm the modification and overwrite the original G code file with the modified data, ensuring the update of the file. By reloading the new data, the cutting process can continue based on the modified file.

[0066] The present invention is further configured such that the data displayed in step S13 includes G-code positioning / interpolation instruction data or encapsulated processing graphics macro program call instructions; specifically, the positioning instructions in the G-code control the movement trajectory of the laser cutting machine, and the positioning instructions include G00 and G01. The positioning instructions generally include coordinate positions, such as X, Y, and Z coordinates, and other states of the cutting head, such as angle or depth. For example, G01X100Y100Z0.5F200 means that the cutting head moves from the current position to the point X=100, Y=100, Z=0.5 along a straight line, and the cutting speed is 200; the interpolation instruction is used to determine the continuity and accuracy of the path and control the movement mode of the cutting head. Interpolation is usually implemented by an interpolation algorithm, which includes linear interpolation and circular interpolation. The purpose is to make the cutting head move smoothly along the specified path. For example, G02X50Y50I25J25 means that the cutting head moves along an arc path from the current point to the coordinates of X=50, Y=50, and the offset of the center of the circle is I=25, J=25; in step S13, when the cutting is paused, the positioning and interpolation instruction data will be displayed on the user interface, so that the user can clearly see the current position, movement path and cutting requirements of the cutting head, and can adjust the movement mode and path of the cutting head according to these data to correct the actual deviation; in laser cutting, some complex cutting paths and operations, such as specific graphic shapes or process parameters, can be It is encapsulated by a macro program. A macro program is a predefined instruction set that simplifies the input of repetitive operations and makes the operation more efficient. For example, a user can perform complex cutting operations by calling a packaged macro program without having to manually enter each instruction. Macro programs are usually activated using a specific calling format, such as G65Pxxxx. For example, G65P8500A30B100C200 may mean calling a macro program numbered 8500 and passing A=30, B=100, and C=200 as parameters. The called macro program contains actual G code instructions, which will be executed during the cutting process and determine parameters such as the cutting path and speed. In step S13, when the cutting is paused and the current line data is displayed, the packaged processing graphics macro program call instruction will also be displayed. The user can see the currently executing macro program and its passed parameters, and adjust the macro program call or parameters as needed, providing the user with a more flexible control method and being able to accurately correct or adjust the cutting path, speed and process.

[0067] The present invention is further configured such that the macro program is an independent .CNC or .NC file, which is called in the format of G65P_A_B_C_I_J_K..., and parameter transfer follows the macro program variable mapping rules; specifically, .CNC or .NC files are universal numerical control file formats, which are used to store cutting instructions required for numerical control machine tools, such as laser cutting machines. The files usually contain multiple G-code instructions for controlling the movement, processing path, speed, process, etc. of the cutting head. As a specific numerical control program, the macro program performs complex operations through these instructions; its parameters are transferred by calling G65P_A_B_C_I_J_K..., and the parameter transfer method complies with the macro program parameter transfer rules, such as G65P8500A30.C2.I30.J90.K0.I0.2J9101., G65 represents the instruction for calling the macro program, G Instruction 65 is a commonly used "macro call instruction", indicating that the CNC system needs to execute a macro program. P8500 represents the number of the macro program to be called, A30 represents #1=30 in the 8500 macro program, C2 represents #3=2 in the 8500 macro program, I30 represents #4=30 in the 8500 macro program, J90 represents #5=90 in the 8500 macro program, K0 represents #6=0 in the 8500 macro program, I0.2 represents #7=0.2 in the 8500 macro program, and J9101 represents #8=9101 in the 8500 macro program. After the above parameters are passed to the macro program, the macro program will perform specific operations or calculations based on these parameters. In this way, users can flexibly modify the input of the macro program without modifying the content of the macro program itself. The order and type of parameter passing must be consistent with the predefined rules of the macro program.

[0068] The present invention is further configured such that the S2 operation process is as follows Figure 4 Specifically shown include:

[0069] S21: Create a blank editing interface and insert a program header macro program; specifically, in the software system, a new cutting program editing window is opened, providing a blank interface for inputting and editing G codes. In the blank editing interface, the software system automatically inserts a program header macro program. The macro program is usually the beginning of the cutting program and is responsible for setting the initial state of the cutting machine. The program header macro program may include laser cutting switch control, cutting machine state setting, and work coordinate system setting.

[0070] S22: Move the cutting head to record the coordinates of the contour points and insert corresponding instructions. Specifically, the user can manually or automatically guide the cutting head to move along the path to be cut and record the coordinates of each contour point. When the cutting head passes each contour point, the software system automatically generates a G-code instruction corresponding to the point and inserts it into the program. The G-code instructions here include positioning and interpolation instructions, which are used to control how the laser cutting machine moves along the path.

[0071] S23: Insert cutting speed parameters and process macro program at the specified position; Specifically, in the cutting process, cutting speed is a key process parameter that determines the accuracy and efficiency of laser cutting. The software system allows users to specify the cutting speed parameters of certain positions in the program, usually controlled by the F parameter in the G code. The speed parameter setting interface is as follows: Figure 7 As shown in the figure, specific processes may be used in the cutting process, including switching laser and coolant control. The software system allows users to insert process macro programs and execute corresponding process steps by calling pre-defined macro programs. The process parameter setting interface is shown in the figure. Figure 8 As shown;

[0072] S24: inserting a cutting end macro program after completing the contour; specifically, when the cutting program completes cutting a certain contour, the software system will automatically determine and end the definition of the current contour. Each contour may be composed of multiple path points. The software system needs to ensure that the G code instructions of all path points have been inserted. When the cutting of a contour is completed, the software system will insert a "cutting end" macro program. This macro program usually includes operations such as stopping the laser, returning to the starting position, and shutting down the cutting machine to ensure the smooth completion of the cutting process and the return of the equipment to a safe state.

[0073] S25: Loop to generate multiple contour paths until all contours are loaded; specifically, steps S22 to S24 describe the cutting process of a contour, and the software system will continue to process the next contour after each contour is completed until all cutting contours are loaded into the program;

[0074] S26: Output the complete G-code program after real-time preview confirmation; specifically, the real-time preview includes path simulation and collision detection functions; after the user completes editing the cutting program, the software system will provide a real-time preview function to display the complete cutting path and simulate the motion trajectory of the cutting head, so that the user can check whether the cutting path meets the requirements, whether there are any misoperations or path deviations, whether there are any redundant paths or unreasonable paths, etc.; through path simulation, the user can see the expected motion path of the laser cutting head on the software interface, which helps to confirm the correctness of the cutting path and avoid errors during actual cutting; during the preview process, the software system will also perform collision detection to check whether the cutting head may collide with the workpiece or machine tool. Through collision detection, the user can promptly discover potential safety hazards or path design problems to avoid damage to the equipment or poor cutting effects; after confirming that the preview is correct, the user can click the "Confirm" button, and the software system will generate and output a complete G-code cutting program. All cutting paths, parameters and macro programs are integrated into a complete cutting program that can be directly used for cutting on a laser cutting machine.

[0075] The present invention is further configured such that the corresponding instruction types include G-code positioning / interpolation instructions and graphic instructions; specifically, the positioning instructions in the G-code are used to control the precise movement of the cutting head; the interpolation instructions are used to automatically generate a path based on a given starting point and end point; and the graphic instructions refer to the use of encapsulated macro programs to achieve complex graphic shape cutting, which are used to automatically generate specific graphic paths during the cutting process, such as circles, rectangles, and complex contours, without the need for the user to manually write each G-code instruction.

[0076] The present invention is further configured such that step S22 specifically includes:

[0077] Clicking the positioning command directly inserts the current coordinates. Specifically, the positioning command is used to control the precise movement of the laser cutting head. When the user clicks the positioning command button on the interface, the software system will obtain the current position coordinates of the cutting head, and the coordinates will be automatically inserted into the generated G code. The command will control the cutting machine to quickly locate from the current position or cut at a specified speed.

[0078] When you click on a graphic instruction, a parameter configuration interface pops up. The graphic instruction is a pre-packaged graphic macro file. Specifically, when the user selects a graphic instruction, the software system pops up a parameter configuration interface. The user enters parameters such as the size, position, and direction of the graphic. The software system generates a corresponding macro program based on these parameters and inserts it into the G code to achieve cutting tasks of different sizes and shapes. The graphic parameter configuration interface is as follows: Figure 9 As shown;

[0079] Automatically optimize the number of path points when continuously collecting points; specifically, path point optimization means that when continuously collecting cutting path points, the software system automatically optimizes the number of path points based on the multiple points that have been collected. By automatically optimizing the number of path points, the cutting process is ensured to be more efficient, while reducing unnecessary calculations and movements, making the cutting process more accurate and energy-saving.

[0080] The present invention is further configured such that the program header macro is only inserted into the first line of the file; the speed parameters, process macros and end macros are inserted at a position determined by the selected line position, and are inserted at the end by default when not selected; specifically, the program header macro is the beginning part of the program, and it will only be inserted into the first line of the G-code file, usually used to initialize the cutting process and define some basic parameters or preset instructions; the insertion position of the speed parameters, process macros and end macros is determined according to the specific line selected by the user in the program. When the user does not select a specific line, these instructions will be inserted at the end of the G-code file by default, which can ensure that the settings of parameters such as speed and process during the cutting process do not affect the execution order of other instructions.

[0081] The present invention is further configured so that all instruction data in the generated G-code program supports secondary editing operations, including deleting specified lines, modifying positioning / interpolation instruction coordinate values, and adjusting macro program call parameters. The secondary editing operation retains the original instruction type and only modifies the parameter value. Specifically, the generated G-code program is not a file that is generated and executed once. The user can modify and adjust it after generation. The secondary editing operation enables the user to flexibly adjust the existing G-code. When the user performs secondary editing, the instruction type in the G-code, such as positioning / interpolation instructions and macro program call instructions, will not change. Only the parameter value in the instruction will be modified, reducing unnecessary complexity.

After the adjustment is completed, the edited data will overwrite the original file and be reloaded. The preset operation mode includes manually moving the cutting head and recording the real-time coordinates and modifying the positioning / interpolation instructions or macro program call parameters in the G-code;

[0085] Cutting program editing and generation module: used to input cutting programs and set cutting parameters in the software editing interface. The cutting parameters include cutting speed and process type, and move the cutting head to the specified position to execute the cutting instructions. By inserting relevant instructions and macro programs in the display list, the definition and editing of each cutting contour are completed and the G-code program is generated.
