At the same time, the posture is carried out according to the fixed posture; the middle position of the web P7 = (0, 0, wt), the cutting gun posture is opposite to the outer side of the wing plate, and these points P5, P6, Pyps, P7 are connected to form a processing tool path.

[0043] Web Y-path: It is a mirror image of the Y+path and is the path for machining the other side.

[0044] In some embodiments, cutting from the inner side of the upper edge of the wing panel to the inner side of the middle of the wing panel as the first tool path includes: The direction from the inner side of the upper edge of the wing panel to the inner side of the middle of the wing panel is used as the first tool path for cutting, and the corner position between the inner side of the upper edge of the wing panel and the inner side of the middle of the wing panel is cut according to a quarter arc.

[0045] It can be understood that the corner position is realized according to a standard arc, which is a quarter arc. Through trigonometric functions, the Y-axis coordinate and the Z-axis coordinate are calculated by multiplying the radius by the angle every 5 degrees to obtain the points on the arc and form continuous processing points Pyps.

[0046] In some embodiments, the target angle is the angle between a cutting gun of a laser cutting machine and the wing panel, and the target angle ranges from 30 to 75 degrees.

Through trigonometric functions, at every 5-degree angle, the Y-axis coordinates and the Z-axis coordinates are calculated by multiplying the radius by the angle to obtain the points on the arc, forming continuous processing points Pyps. At the same time, the posture is fixed; the middle position of the web P7 = (0, 0, wt), the cutting gun posture is opposite to the outer side of the wing plate, and these points P5, P6, Pyps, P7 are connected to form a processing tool path.

[0055] Step 3: Processing tool path sequence: There are two types, one is to process the wing plate first, and then process the web plate, such as Figure 3 Another method is to process the web first and then the wing plate, as shown in Figure 4 When processing the wing plate, first locate the processing point on the upper part of the wing plate, and process from top to bottom. When processing the web plate, first start from the inner side of the upper part of the wing plate, and process from top to bottom until the center of the web plate.

[0056] Step 4: Assign the machining tool path to the nesting code and proofing code: According to the data in step 2, the data of the tube length direction is assigned, and it is detected whether there is a vertical cut in the part. If there is a vertical cut, the processing tool path of the vertical cut is assigned according to step 2 to realize the processing tool path generation.

[0057] Step 5: Output the calculated processing code as a processing file: The system is bound by the protocol, and the spatial coordinates and postures in the machining tool path are converted into machining files, and a data stream is converted and output.
