TECHNICAL FIELD

[0001] The application belongs to the technical field of laser processing, and more particularly to a laser multi-angle groove cutting method and a computer readable storage medium. BACKGROUND

[0002] The current mainstream computer-aided manufacturing (CAM) system has realized basic technology coverage in the field of planar groove machining, and its core functions include conventional single-groove programming, which can meet the machining needs of most industrial scenes.

[0003] However, as the process requirements for complex welded structural parts in the field of precision manufacturing continue to upgrade, some high-end users have gradually proposed more stringent machining requirements - the workpiece groove surface needs to present two or more continuous cutting surfaces of different angles. The existing CAM software is limited by the linear programming architecture of single-angle grooves, and there are significant technical bottlenecks in processing such multi-angle composite grooves. The operator has to adopt a staged machining strategy, that is, through multiple clamping and repeated positioning, the cutting operation of different angles is completed. This secondary machining process greatly reduces production efficiency. SUMMARY

[0078] Please refer to Figures 1 to 8 The laser multi-angle groove cutting method provided by the embodiments of the present application will now be described.

[0079] With reference to Figure 2 The laser multi-angle groove cutting method provided by the embodiments of the present application includes the following steps:

[0080] S1: Obtain a target contour line of a workpiece to be cut, a type of groove cutting, and groove cutting parameters.

[0081] In step S1, an operator imports a planar geometry of the workpiece to be cut into the cutting equipment system, activates a multi-angle groove function module, and selects a target contour line. At the beginning of the laser multi-angle groove cutting process, the primary operation is to import the planar geometry of the workpiece to be cut. The system supports common CAD file formats such as DXF and DWG, and can accurately identify the contour line segments, arcs, and other geometric elements of the workpiece with the help of a graphic parsing engine. When the multi-angle groove function module is activated, the graphic interface will present the editable line segments in high light, and the user can select the target cutting line segment through convenient operations such as frame selection and point selection. At the same time, the system automatically analyzes the geometric properties of the line segment and constructs a corresponding coordinate system in three-dimensional space. In this way, the physical workpiece is converted into a digital model, laying a solid foundation for subsequent parameterized programming, and ensuring that the parameters correspond accurately to the actual processing position, greatly reducing the errors that may be caused by manual measurement.

[0082] S2: According to the type of groove cutting and the groove cutting parameters, a pre-defined mapping relationship model is called to calculate the starting point coordinate offset and cutting path of each cutting segment.

[0083] Referring to Figure 1 and Figure 3 , after completing the graphic import and line segment selection, step S2 is entered, and the system will provide a special parameterized input interface for the user to input key processing parameters.

[0084] The cutting equipment system receives the type of groove cutting and the groove cutting parameters input by the user, wherein the groove cutting parameters can include a number of layering intersection lines 20 parameter N, a cutting angle parameter, a layering thickness parameter, and a total material thickness parameter, wherein N is the number of adjacent groove face intersection lines or groove face and vertical face intersection lines to be generated along the thickness direction of the plate 10, and N≥1.

[0085] The number of layering intersection lines 20 parameter N determines the number of inflection points when cutting the groove face, and there are different thickness layerings, and the cutting of each layering can set an independent cutting angle. Understandably, N is a positive integer.

[0086] The layering thickness parameter specifies the thickness (height) of each layer; the angle parameter supports both absolute angle and relative angle input. These parameters together construct the geometric definition of the multi-angle groove, and the system will also automatically verify the process feasibility according to the input, such as checking angle conflicts and whether the cutting depth is out of limit. Parameterized design gives high flexibility to process adjustment, so that the cutting can adapt to different materials and welding requirements of the processing scene.

[0087] The cutting device system calls a predefined mapping relationship model according to the user-specified groove type, combines the layered interface line number parameter N, the cutting angle parameter, the layered thickness parameter, and the total material thickness parameter to calculate the cutting point coordinate offset and the cutting path of each cutting section.

[0088] In this step, the system will call a predefined mapping relationship model according to the user-specified groove type, such as V-type, A-type, Y-type, X-type, or K-type. These models are based on geometric algorithms and kinematic principles to convert the input parameters into the spatial motion trajectory of the laser head. The calculation process covers determining the lateral offset of each layer according to the angle and layered thickness, obtaining the cutting point and finishing point coordinates combined with the line segment length, and planning the optimal cutting sequence through a path optimization algorithm. This step replaces manual programming with automatic calculation, significantly shortening the programming time, and the optimized path planning reduces the device idle travel. Precise coordinate offset calculation also ensures high precision of the groove angle.

[0089] S3: Convert the coordinate offset and cutting path into a set of motion control instructions for the laser cutting head, and drive the device to complete multi-angle continuous groove cutting in a single clamping.

[0090] Finally, the system converts the calculation results into a standard G-code instruction set, embeds process parameters such as laser power and focal length, and performs three-dimensional motion simulation through a virtual machining interface to detect possible path conflicts or device interference in advance. After confirmation, the laser cutting head automatically positions according to the instructions and starts continuous multi-angle cutting from the cutting point. During the process, key parameters such as temperature and focal point offset are monitored in real time, and the processing state is dynamically adjusted.

[0091] By converting the calculation results into executable instructions for the device, multi-angle continuous groove cutting is achieved in a single clamping, eliminating positioning errors caused by multiple clamping, reducing the number of device start-stop times, and avoiding the cumulative errors and low processing efficiency caused by multiple clamping and repeated positioning in traditional stage-by-stage processing. This effectively improves production efficiency, enhances processing precision, and improves the adaptability of multi-angle groove machining for complex welding structure components, meeting the strict requirements of high-end users in the precision manufacturing field.

[0092] Further, in step S2, the groove cutting parameters include a layered interface line number parameter N, a cutting angle parameter, a layered thickness parameter, and a total material thickness parameter, where N is the number of adjacent groove face intersection lines or groove face and vertical face intersection lines to be generated along the thickness direction of the plate, N≥1; the cutting angle parameter is N+1 cutting angles θ1-θN, satisfying 0°≤θ1<θ2<…<θN≤60°, or including multiple independent increasing angle sequences. N+1 N+1

[0093] ​​In the embodiments of the present application, the setting of the cutting angle parameter fully considers the diversity requirements of complex groove structures. Specifically, the cutting angle parameter includes N+1 angles θ1-θ N+1 , which needs to satisfy the strict increasing relationship 0°≤θ1<θ2<…<θ N+1 ≤60°.

[0094] For more complex multi-section composite grooves (such as X-type and K-type), a combination mode of multiple groups of independent increasing angle sequences is also allowed. For example, in X-type groove processing, the number parameter N of layer junction lines is 3, which corresponds to four cutting angles θ1, θ2, θ3, θ4. They can be divided into two groups of independently controlled angle sequences 0°≤θ1<θ2≤60° and 0°≤θ3<θ4≤60°, and each group of angles increases in its interval, thereby adapting to the symmetric or asymmetric composite groove geometric characteristics. This design, through mathematical segmentation modeling, not only guarantees the processing precision of a single continuous groove (such as V-type and Y-type), but also provides a flexible angle configuration space for multi-section special-shaped grooves (such as cross-symmetric X-type and multi-directional expansion K-type), so that the angle change rule of different regions of the same workpiece can be independently defined, and finally the one-time forming cutting of complex welding structural parts is realized, completely solving the design limitation problem caused by the single angle in the traditional process.

[0095] Further, in step S2, the layer thickness parameter includes the orthogonal blunt edge thickness H0 and the layer thickness H1-H N+1-K , and the value of K is 0 or 1, which is determined by the groove type specified by the user, wherein:

[0096] When the groove type contains an orthogonal blunt edge, H0>0, K=1, and the total thickness of H0 and H1-H N is equal to the total thickness H of the plate 10.

[0097] When the groove type does not contain an orthogonal blunt edge, H0=0, K=0, and the total thickness of the layer thickness H1-H N+1 is equal to the total thickness H of the plate 10.

[0098] In the embodiments of the present application, the setting of the layer thickness parameter realizes the fine control of the groove structure by introducing the orthogonal blunt edge flag K value. Specifically, the layer thickness parameter includes the orthogonal blunt edge thickness H0 and the layer thickness H1-H N+1-K , wherein the value of K is dynamically determined by the groove type specified by the user.

[0099] When the groove type contains an orthogonal blunt edge, such as Y-type, X-type, and K-type, K=1, at this time the system requires that the input H0>0, and the layer thickness parameter is reduced to H1-H N . The total thickness needs to satisfy H0+H1+H2+…+H N= H, where H0 represents the thickness of the bevel perpendicular to the cutting surface, and the remaining layer thicknesses H1~H N correspond to different angle bevel segments. For example, when processing a K-type bevel (N = 4), the layering parameters are H0, H1, H2, H3, and H4, and the total thickness constraint is H0 + H1 + H2 + H3 + H4 = H. The presence of H0 ensures the material integrity of the bevel region.

[0100] When the bevel type does not contain a perpendicular bevel (such as V-type, A-type), K = 0, at which time H0 = 0, and the layering thickness parameters expand to H1~H N+1 , and the total thickness constraint is H1 + H2 + … + H N+1 = H. For example, the layering parameters for a V-type bevel (N = 1) are H1 and H2, which must satisfy H1 + H2 = H. The system directly generates the cutting path through the formulas X1 = tanθ1 × H1 and X2 = tanθ2 × H2 + tanθ1 × H1, without considering bevel compensation.

[0101] This design achieves the following technical advantages by dynamically adjusting the parameter N + 1 - K:

[0102] 1. Parameter adaptation flexibility: The K value divides bevel types into two categories: "with bevel" and "without bevel". Users do not need to manually switch calculation models, and the system automatically matches parameter logic. For example, when processing a Y-type bevel, K = 1 triggers the bevel calculation module, while for a V-type bevel, K = 0 activates the simplified model, reducing operational complexity.

[0103] 2. Thickness distribution accuracy: Layering thickness is strictly bound to cutting angle, for example, in an X-type bevel, θ1, θ2 correspond to H1, H2, θ3, θ4 correspond to H3, and H0 independently controls the bevel region, ensuring that the geometric dimensions of each bevel segment are consistent with design requirements.

[0104] 3. Improved process compatibility: By distinguishing the presence of bevels through K values, the system can cover all scenarios from simple single bevel to multi-segment composite bevel processing requirements. For example, a certain aerospace fuel tank welding piece requires both V-type interfaces (K = 0) and Y-type reinforcement ribs (K = 1). The system automatically switches parameter modes in one clamping, avoiding the need for multiple adjustments in traditional processes due to model incompatibility.

[0105] Further, in step S2, the bevel type includes at least one of a V-type bevel, an A-type bevel, a Y-type bevel, an X-type bevel, and a K-type bevel, each corresponding to different cutting sequence rules and coordinate offset calculation models;

[0106] Among them, the V-type bevel and the A-type bevel correspond to K = 0; the Y-type bevel, the X-type bevel, and the K-type bevel correspond to K = 1.

[0107] In the embodiments of the present application, the groove type is divided into two categories according to whether it contains a normal bevel, and is dynamically distinguished by a flag parameter K value.

[0108] For V-type and A-type grooves, the system sets K=0, indicating that no normal bevel is included. The cutting sequence of such grooves usually adopts a one-way continuous or reverse path, and the coordinate offset calculation model directly relates the user input layer thickness and cutting angle to generate straight or inclined cutting trajectories through a simplified mathematical relationship, ensuring fast processing of single-slope surface structures.

[0109] For Y-type, X-type and K-type grooves, the system sets K=1, which forces the normal bevel parameter H0 to be enabled and the user to input specific data. Such grooves require additional processing of the bevel area perpendicular to the workpiece surface during cutting, so the cutting sequence is usually designed as a multi-segment composite path, such as alternating expansion or convergence from the bevel. The coordinate offset calculation model combines the bevel thickness H0 and the layer thickness parameter to dynamically adjust the starting point position of each cutting segment through a piecewise function or superposition formula to adapt to the forming requirements of complex geometric shapes. Through intelligent judgment of the K value, the system can automatically switch the calculation logic, retaining the efficiency of basic grooves while providing precise multi-angle collaborative control for composite structures, thereby achieving diversified groove shapes in a single machining process.

[0110] Further, in the calculation of step S2, when the number of layer intersection lines 20 is N=1 and the groove type is a V-type groove, the two ordered angles θ1, θ2 satisfy 0°≤θ1<θ2≤60°.

[0111] The cutting sequence rule is forward continuous cutting, and the cutting paths are X1, X2 in turn.

[0112] The corresponding coordinate offset calculation model satisfies:

[0113] X1=tanθ1×H1,

[0114] X2=tanθ2×H2+tanθ1×H1,

[0115] where X1 and X2 are the horizontal offsets of the starting points of θ1 and θ2, respectively, and the normal bevel thickness H0=0.

[0116] In the embodiments of the present application, for the processing requirements of V-type grooves, when the user sets the number of layer intersection lines N=1, the system automatically generates two ordered cutting angles θ1, θ2, whose value range is strictly limited to 0°≤θ1<θ2≤60°. The user needs to input the corresponding layer thickness parameters H1, H2 and the total material thickness H, and the system ensures H1+H2=H through the built-in verification module, while forcing the normal bevel thickness H0=0 to adapt to the structural characteristics of V-type grooves without a perpendicular bevel.

[0117] For such a V-shaped groove cutting, the system follows the sequence rule of forward continuous cutting, and the cutting path is X1, X2 in turn. This means that the laser cutting head will complete the entire V-shaped groove cutting along the set path from the starting end in a coherent and smooth manner, avoiding unnecessary backtracking or stopping, effectively improving the cutting efficiency. In actual operation, the cutting head first cuts along the path X1 corresponding to the angle θ1 according to the pre-planned sequence, and then seamlessly connects to the path X2 corresponding to the angle θ2, completing the groove machining in one breath.

[0118] The key to accurately realizing the cutting path planning lies in the corresponding coordinate offset calculation model behind it. Since the K value corresponding to the V-shaped groove is 0, i.e., it does not contain an orthogonal blunt edge, the influence of the orthogonal blunt edge thickness H0 does not need to be considered in the calculation.

[0119] Referring to Figure 3 , Figure 3 is a schematic diagram of V-shaped groove cutting. It can be seen that tanθ1 = ΔX / H1, tanθ2 = ΔX / ΔH, tanθ2 = X2 / (H2+ΔH). According to the model formula, X1 = tanθ1 × H1,

[0120] X2 = tanθ2 × H2 + tanθ1 × H1, where X1 and X2 respectively correspond to the horizontal offset of the starting point of θ1 and θ2. Based on the principle of trigonometric functions, these two formulas can accurately calculate the offset distance of the starting point of each cutting path in the horizontal direction by combining the cutting angle θ with the layer thickness H.

[0121] For example, when cutting a certain metal plate 10, it is known that θ1 is 30° and H1 is 5mm. By the formula X1 = tan30° × 5mm, the horizontal offset of the starting point of the corresponding path X1 can be calculated. Combined with the values of θ2 and H2, the offset of X2 can be obtained, thereby providing accurate coordinate guidance for the motion trajectory of the laser cutting head, ensuring that the angle and size of the V-shaped groove cut out can strictly meet the design standard, and laying a solid quality foundation for the subsequent welding process.

[0122] Further, in the calculation of step S2, when the number of layer boundaries 20 is N = 1 and the groove type is A-shaped groove, the two ordered angles θ1 and θ2 satisfy 0°≤θ1<θ2≤60°;

[0123] The cutting sequence rule is reverse continuous cutting, and the cutting path is X2, X1 in turn;

[0124] The corresponding coordinate offset calculation model satisfies:

[0125] X2 = H1 × (tanθ2 - tanθ1),

[0126] X1 = 0,

[0127] wherein X2 corresponds to the horizontal offset of the starting point of θ2, X1 is the starting point of θ1, and the orthogonal blunt edge thickness H0 = 0.

[0128] In the embodiments of the present application, when the number parameter N of the layered interface line 20 is 1 and the groove type is selected as the A-type groove, the system will start a set of exclusive processing logic adapted to this special working condition. At this time, the system focuses on two ordered angles θ1, θ2 that satisfy 0°≤θ1<θ2≤60°. This angle interval setting not only guarantees the safety and feasibility of the cutting operation, but also meets the precision requirements of the groove angle for the subsequent welding process.

[0129] Unlike other groove types, the cutting sequence rule of the A-type groove adopts a reverse continuous cutting mode, and its cutting path is X2, X1 in turn. This reverse cutting design is based on the structural characteristics and processing characteristics of the A-type groove. In actual operation, the laser cutting head will first cut along the path X2 corresponding to the angle θ2, and then reverse to the path X1 corresponding to the angle θ1 to complete the cutting process of the entire groove in a coherent and smooth manner. Such an arrangement can effectively reduce the energy loss and position deviation caused by frequent switching of direction during cutting, and improve the stability and efficiency of cutting.

[0130] Since the K value corresponding to the A-type groove is 0, there is no orthogonal blunt edge structure, and the model presents a unique calculation logic when calculating the horizontal offset of the starting point.

[0131] Referring to Figure 4 , Figure 4 is a schematic diagram of the A-type groove cutting. It can be seen that ΔX = H1 × tanθ1, tanθ2 = ΔX / ΔH, tanθ2 = X2 / (H1-ΔH). According to the formula X2 = H1 × (tanθ2-tanθ1), X1 = 0, wherein X2 corresponds to the horizontal offset of the starting point of θ2, and X1 is directly set to 0, i.e. the starting point of θ1 is located at the starting position. This calculation method correlates the cutting angle θ and the layered thickness H1 through the relationship of trigonometric functions, thereby accurately determining the horizontal offset distance of the starting point of each cutting path. For example, when processing a certain metal component, H1 is 8 mm, θ1 = 20°, and θ2 = 40°. Through the formula, the value of X2 can be accurately calculated to provide accurate coordinate guidance for the motion trajectory of the laser cutting head, ensuring that the A-type groove angle and size cut out completely meet the design requirements, effectively guaranteeing the welding quality and the overall performance of the component.

[0132] Further, in the calculation of step S2, the Y-type groove includes an upper Y-type groove and a lower Y-type groove. That is, in the actual application of the laser multi-angle groove cutting technology, the Y-type groove is widely concerned due to its unique structural design and wide applicability, which is further divided into an upper Y-type groove and a lower Y-type groove, and different types correspond to different cutting logic and parameter calculation methods.

[0133] When the number of layering interface lines 20 is N=2 and the groove type is an upper Y-type groove, three ordered angles θ1, θ2, θ3 satisfy 0°<θ2<θ3≤60°.

[0134] The cutting sequence rule is three-section forward cutting, and the cutting path is X0, X1, X2 in turn.

[0135] The corresponding coordinate offset calculation model satisfies:

[0136] X0=0,

[0137] X1=tanθ1×(H1+H2),

[0138] X2=tanθ3×H1+tanθ2×H1,

[0139] wherein X0, X1, X2 are the horizontal offsets of the starting points corresponding to θ1, θ2, θ3 respectively, and the orthogonal blunt edge thickness H0>0.

[0140] When the number of layering interface lines 20 is N=2 and the groove type is an upper Y-type groove, the system will work around three angles θ1, θ2, θ3, wherein θ1 is fixed at 0°, and θ2 and θ3 need to satisfy the angle range requirement of 0°<θ2<θ3≤60°.

[0141] Referring to Figure 5 , Figure 5 is a schematic view of upper Y-type groove cutting. It can be seen that tanθ3=ΔX / ΔH, tanθ2=ΔX / H1, and tanθ3=X2 / (H2+ΔH).

[0142] In this working condition, the cutting sequence rule adopts three-section forward cutting, and the cutting paths are X0, X1 and X2 in sequence. When the cutting starts, the laser cutting head starts from the X0 path with an offset of 0, which corresponds to θ1=0°, that is, the blunt edge part is cut along the vertical direction first; then the X1 path is sequentially traveled to, and the horizontal offset is calculated according to the formula X1=tanθ1×(H1+H2), and the cutting of the intermediate angle θ2 is completed; finally, the X2 path is followed, and the offset is determined by the calculation result of X2=tanθ3×H1+tanθ2×H1, and the cutting of the top angle θ3 is completed, so that the shape of the upper Y-type groove is completely shaped. Since the upper Y-type groove corresponds to K=1, there is a right-angle blunt edge, and the thickness H0>0, by accurately calculating the offset during the cutting process, the complete retention of the blunt edge is ensured, and the transition of the groove angle is natural.

[0143] In another case, in the calculation of step S2, when the number of layered interface lines 20 is N=2 and the groove type is a lower Y-type groove, three angles θ1, θ2 and θ3 satisfy 0°<θ2<θ3≤60°, and θ1=0°.

[0144] The cutting sequence rule is three-section forward cutting, and the cutting paths are X2, X1 and X0 in sequence.

[0145] The corresponding coordinate offset calculation model satisfies:

[0146] X2=tanθ3×(H0+H1)-tanθ2×H1,

[0147] X1=tanθ1×H0,

[0148] X0=0,

[0149] Wherein, X0, X1 and X2 are the horizontal offsets of the starting points corresponding to θ1, θ2 and θ3 respectively, and the thickness of the right-angle blunt edge H0>0.

[0150] Referring to Figure 6 , Figure 6 is a schematic view of a lower Y-type groove. It can be seen that tanθ2=ΔX / H1, tanθ3=ΔX / ΔH, and tanθ3=X2 / (H0+H1-ΔH).

[0151] When the number parameter N of the layered interface lines 20 is 2 and the lower Y-type groove type is selected, three ordered angles θ1, θ2, θ3 are processed, and θ1=0°, θ2 and θ3 satisfy 0°<θ2<θ3≤60°. However, the cutting sequence rule is also three-section forward cutting, but the cutting path is adjusted to X2, X1, X0, which is related to the structure characteristics of the lower Y-type groove with the top wide and the bottom narrow. During cutting, the laser cutting head starts work along the X2 path first, the starting point horizontal offset is calculated by the formula X2=tanθ3×(H0+H1)-tanθ2×H1, and the θ3 angle at the bottom is cut; then it moves to the X1 path, and the θ2 angle at the middle is cut according to the calculation result of X1=tanθ1×H0; finally, it returns to the X0 path, and the top blunt edge is cut because its offset X0=0. Through such path planning and coordinate offset calculation, combined with the orthogonal blunt edge setting of H0>0, the lower Y-type groove can be accurately cut, meeting the high-precision requirements of Y-type grooves in different welding scenes and ensuring that the cut groove realizes firm and reliable connection effect in actual welding.

[0152] Whether it is an upper Y-type groove or a lower Y-type groove, such accurate cutting setting based on the structure characteristics of the groove greatly improves the adaptability and reliability of the laser cutting process in the processing of complex welded structure parts.

[0153] Further, in the calculation of step S2, when the number parameter N of the layered interface lines is 3 and the groove type is an X-type groove, the cutting angle parameters are four angles θ1, θ2, θ3, θ4, which are two groups of independent increasing angle sequences, and satisfy 0°≤θ1<θ2≤60° and 0°≤θ3<θ4≤60°;

[0154] The cutting sequence rule is a cross-symmetrical composite path, and the cutting paths are X4, X3, X1, X2 in turn;

[0155] The coordinate offset calculation model satisfies the following formula:

[0156] X4=tanθ4×(H0+H1+H2)-tanθ3×H2,

[0157] X3=tanθ3×(H0+H1),

[0158] X1=tanθ1×(H0+H1),

[0159] X2=tanθ2×H0+tanθ1×H1,

[0160] Wherein, X1, X2, X3, X4 are the horizontal offsets of the starting points corresponding to θ1, θ2, θ3, θ4 respectively, and the orthogonal blunt edge thickness H0>0.

[0161] Referring toFigure 7 , Figure 7 is a schematic diagram of X-type groove cutting. It can be seen that tan θ3 = ΔX1 / H2, tan θ4 = ΔX1 / ΔH1, tan θ4 = X4 / (H0+H1+H2-ΔH1), tan θ2 = ΔX / ΔH, tan θ1 = ΔX / H1, tan θ2 = X2 / (H0+ΔH).

[0162] When the laser multi-angle groove cutting technology is applied to X-type groove machining, when the number of layered interface line parameter N = 3, the system needs to process four ordered angles θ1, θ2, θ3, θ4, which are divided into two groups, respectively satisfying 0°≤θ1<θ2≤60° and 0°≤θ3<θ4≤60°. This angle setting fully considers the characteristics of X-type groove double-sided machining, and through two groups of increasing angles, the groove shape of the two sides of the plate 10 is controlled respectively, so as to ensure that the penetration of the two sides is uniform during welding, and the joint strength is improved.

[0163] For X-type groove cutting, the system adopts a cross-symmetrical composite path strategy, and the cutting sequence is X4, X3, X1, X2. This special path planning is derived from the symmetry of the X-type groove, and through cross cutting, the machining stress can be balanced and the plate 10 deformation can be reduced.

[0164] Specifically, the laser cutting head first cuts along the X4 path, which corresponds to the θ4 angle groove machining, and the horizontal offset of the starting point is determined by the formula X4 = tan θ4 × (H0+H1+H2)-tan θ3 × H2, wherein tan θ3 = ΔX1 / H2, tan θ4 = ΔX1 / ΔH1, tan θ4 = X4 / (H0+H1+H2-ΔH1), this formula considers the relationship between the total thickness of the plate 10 and the adjacent angles, and ensures the accuracy of the cutting starting point. Then, the cutting head processes the θ3 angle groove along the X3 path, and the offset X3 = tan θ3 × (H0+H1). After completing the preliminary cutting on one side, the cutting head switches to the other side, first processes the θ1 angle groove along the X1 path, and the offset X1 = tan θ1 × (H0+H1), and then processes the θ2 angle groove along the X2 path, and the offset X2 = tan θ2 × H0+tan θ1 × H1. Through this cross-symmetrical cutting method, heat concentration and stress accumulation caused by single-sided continuous cutting can be effectively avoided.

[0165] In the coordinate offset calculation, since the X-type groove belongs to the type containing orthogonal blunt edge (K = 1), the orthogonal blunt edge thickness H0>0. This blunt edge plays an important role in the welding process, which can prevent root burn-through and ensure weld forming. The offset calculation of each starting point is closely related to the blunt edge thickness, the layered thickness and the trigonometric function relationship of the corresponding angle. For example, in the calculation of X2, X2 = tan θ2 × H0+tan θ1 × H1.

[0166] tanθ2×H0+tanθ1×H1, which reflects the lateral offset from the top of the blunt edge, while tanθ1×H1 takes into account the influence of the lower layer cutting on the starting point of the current layer. This accurate calculation model ensures that the four different angle bevels can be accurately machined on both sides of the plate 10, meeting the strict requirements of X-type bevels for double-face angle consistency and symmetry.

[0167] Further, in the calculation of step S2, when the layered interface line number parameter N = 4 and the bevel type is K-type bevel, the cutting angle parameters are five angles θ1, θ2, θ3, θ4, θ5, which are two groups of independent increasing angle sequences, wherein θ1 = 0°, 0° < θ2 < θ3 ≤ 60°, 0° < θ4 < θ5 ≤ 60°;

[0168] The cutting sequence rule is a cross-symmetrical composite path, and the cutting paths are X5, X4, X1, X2, X3 in turn;

[0169] The coordinate offset calculation model satisfies the following formula:

[0170] X5 = tanθ5×(H0+H1+H2+H3) - tanθ4×H3,

[0171] X4 = tanθ4×(H0+H1+H2+H3),

[0172] X1 = 0,

[0173] X2 = tanθ2×(H1+H2),

[0174] X3 = tanθ3×H2 + tanθ2×H1,

[0175] Wherein, X1, X2, X3, X4, X5 are the starting point lateral offsets corresponding to θ1, θ2, θ3, θ4, θ5 respectively, and the orthogonal blunt edge thickness H0 > 0.

[0176] In the application of laser multi-angle bevel cutting to K-type bevel machining, and when the layered interface line number parameter N is set to 4, the system carries out accurate control around the five angles θ1, θ2, θ3, θ4, θ5, wherein θ1 is fixed at 0°, and θ2 and θ3, θ4 and θ5 respectively satisfy the angle interval requirements of 0° < θ2 < θ3 ≤ 60° and 0° < θ4 < θ5 ≤ 60°. This angle setting fits the complex structure characteristics of the double-sided asymmetry of K-type bevel, with the vertical blunt edge (θ1 = 0°) as the basis, and the two sides of the slope are shaped by two groups of increasing angles.

[0177] Reference Figure 8, which is a schematic diagram of K groove. It can be seen that tanθ1=ΔX / H1, tanθ2=ΔX / ΔH, tanθ2=X2 / (H2+ΔH), tanθ3=ΔX1 / H3;

[0178] tanθ4=ΔX1 / ΔH1, tanθ4=X4 / (H0+H1+H2+H3-ΔH1).

[0179] For this working condition, the system adopts a cross-symmetrical composite path as the cutting sequence rule, and the cutting path is X5, X4, X1, X2, X3.

[0180] After the cutting starts, the laser cutting head first processes the slope surface corresponding to the θ5 angle along the X5 path, and the horizontal offset of the starting point is calculated according to the formula X5=tanθ5×(H0+H1+H2+H3)-tanθ4×H3. This formula combines the angle parameter with the layer thickness depth to accurately calculate the cutting starting position. Then, the cutting along the X4 path to complete the θ4 angle slope surface is completed, and the offset is calculated and determined by X4=tanθ4×(H0+H1+H2+H3). After completing the cutting on one side, the cutting head switches to the other side, first processes the vertical blunt edge (X1=0) corresponding to θ1, and then completes the remaining slope surface cutting along the X2 path (i.e. offset X2=tanθ2×(H1+H2), X3 path (i.e. offset X3=tanθ3×H2+tanθ2×H1) in turn. The cross-symmetrical cutting path effectively balances the machining stress, avoids deformation of the plate 10 due to local heat concentration, and ensures cutting accuracy.

[0181] Since the K-type groove includes orthogonal blunt edges (K=1, H0>0), the coordinate offset calculation model deeply integrates the blunt edge thickness and the cutting parameters of each layer. For example, the calculation of X3 considers the influence of the layer thickness H2 corresponding to the θ3 angle and the layer thickness H1 corresponding to the θ2 angle, and accurately determines the offset through trigonometric function operation. This refined calculation method enables the cutting head to accurately shape the K-type groove on both sides of the plate 10 according to the setting of the five different angles, realizing the dual requirements of angle gradient and structural symmetry.
