In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features.

[0046] The terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element structure referred to must have a particular orientation, be constructed and operated in a particular orientation.

[0047] Referring to Figure 1 The bevel cutting method provided in the present application comprises the steps of:

[0048] S100, divide the cutting contour of the target workpiece into a plurality of continuous bevel cutting segments, the bevel cutting segments including a regular bevel cutting segment and a gradual bevel cutting segment;

[0049] S300, in the regular bevel cutting segment, adopt a first cutting instruction to cut the target workpiece;

[0050] S500, in the gradual bevel cutting segment, adopt a second cutting instruction to cut the target workpiece, the first cutting instruction and the second cutting instruction adopt different cutting parameters.

[0051] In the cutting process, the corresponding cutting settings can be made on the computer of the numerical control cutting system for the workpiece to be cut, and then the layout, nesting and programming are performed on the workpiece to be cut, so as to improve the workpiece utilization rate by efficient layout, output the bevel cutting instruction NC program, and realize the continuous cutting of various bevel workpieces through the cutting head, thereby improving the cutting efficiency.

[0052] The regular bevel includes a V-shaped bevel, an X-shaped bevel, a K-shaped bevel or an I-shaped bevel. When cutting the regular bevel, the target bevel angle is constant or changes little, and after adjusting the angle between the cutting head and the normal line of the workpiece to be cut according to the target bevel angle, the cutting head can maintain the angle for cutting.

[0053] The shape of the gradual bevel is complex, and the bevel angle will change constantly. When cutting the gradual bevel, the cutting head needs to gradually swing the angle between the cutting head and the normal line of the workpiece to be cut according to the target bevel angle.

[0054] When machining and programming the workpiece with a gradual bevel, the generated cutting instruction is for the entire machining contour of the workpiece, and a part or most of the non-bevel surface or other forms of regular bevels are often mixed in the contour. In order to ensure the stability of the workpiece cutting, the cutting program will call the same cutting instruction to cut the entire contour of the workpiece, resulting in the cutting of the non-bevel surface or other forms of regular bevels, and the generation of instructions for cutting the cutting head at a plurality of changing angles with the normal line of the workpiece to be cut, which increases the cutting difficulty and causes the overall machining speed of the workpiece to decrease.

[0055] For example, when cutting an I-shaped bevel, the cutting angle of the cutting head can be perpendicular to the surface of the workpiece. However, in the cutting instruction generation rule of the gradual bevel, the cutting software will identify the entire cutting contour containing the I-shaped bevel as a gradual bevel contour to be cut, so that the part that can be cut vertically generates instructions for cutting the cutting head at a plurality of changing angles with the normal line of the workpiece to be cut, in order to realize the seamless connection in the cutting of the gradual bevel, so that the program instruction becomes complex.

[0056] Furthermore, the cutting will call the same process parameter to cut the whole cutting contour, so the same cutting speed and cutting gas pressure are used for the conventional bevel and the gradual bevel, which not only leads to the overall slow cutting speed and reduces the processing efficiency, but also causes the corner melting of the target workpiece and the unsatisfactory effect of the cutting end face due to the overall excessive cutting gas pressure.

[0057] The present application can divide the cutting contour of the target workpiece into a plurality of continuous bevel cutting segments, and the division standard is to confirm whether the segment bevel cutting segment is a conventional bevel cutting segment or a gradual bevel cutting segment. If the segment bevel cutting segment is a conventional bevel cutting segment, the target workpiece is cut by using the first cutting instruction, the angle of the cutting head under the first cutting instruction has no change or less change, and a higher cutting speed and a lower cutting gas pressure can be used.

[0058] If the segment bevel cutting segment is a gradual bevel cutting segment, the target workpiece is cut by using the second cutting instruction, the second cutting instruction is the instruction that the cutting head cuts at a plurality of change angles with the normal line of the workpiece to be cut, and a lower cutting speed and a higher cutting gas pressure can be used to ensure the cutting quality.

[0059] Therefore, the bevel cutting method provided by the present application can not only realize the cutting of the workpiece containing the gradual bevel, but also can improve the overall cutting speed of the workpiece, without using manual modification of the workpiece drawing or related auxiliary line segments when programming the cutting software, and without manually modifying the gradual bevel cutting parameters.

[0060] In some embodiments, referring to Figure 2 and Figure 3 , the bevel cutting method further comprises the steps of:

[0061] S10, obtaining the upper surface contour line segment and the lower surface contour line segment of the target workpiece;

[0062] S20, selecting a plurality of connection points which are consistent in number and correspond to each other on the upper surface contour line segment and the lower surface contour line segment of the target workpiece, respectively;

[0063] S30, connecting the corresponding connection points of the upper surface contour line segment and the lower surface contour line segment of the target workpiece based on the thickness of the target workpiece to form a cutting contour of the target workpiece.

[0064] When programming the cutting of the target workpiece, the three-dimensional drawing of the target workpiece can be obtained first, and then the upper surface contour line segment and the lower surface contour line segment of the target workpiece are obtained. Then, the corresponding connection points of the upper surface contour line segment and the lower surface contour line segment are connected in turn at a suitable height according to the thickness of the workpiece input during programming, and finally the cutting contour of the target workpiece is obtained.

[0065] In further embodiments, referring to Figure 4 andFigure 5 , step S100 specifically comprises:

[0066] S110, the projection line segments of the upper surface profile line segment and the lower surface profile line segment of the target workpiece on the same plane are acquired;

[0067] S120, if the interval of the two projection line segments remains a constant value, it is judged that the cutting profile formed by the two profile line segments is a conventional bevel cutting segment;

[0068] S130, if the interval of the two projection line segments does not remain a constant value, it is judged that the cutting profile formed by the two profile line segments is a gradual bevel cutting segment.

[0069] If the interval of the two projection line segments remains a constant value, for example, 0, at this time the two projection line segments coincide, and the connecting points corresponding to the upper surface profile line segment and the lower surface profile line segment of the target workpiece are sequentially connected, the angle of the connecting line formed will be consistent, so that the cutting angle of the cutting head will not change, at this time the first cutting instruction can be used to perform conventional cutting on the target workpiece.

[0070] If the interval of the two projection line segments does not remain a constant value, the connecting points corresponding to the upper surface profile line segment and the lower surface profile line segment of the target workpiece are sequentially connected, the angle of the connecting line formed will constantly change, resulting in the need for the cutting angle of the cutting head to change accordingly, at this time the second cutting instruction can be used to perform gradual cutting on the target workpiece.

[0071] In some embodiments, the bevel cutting method further comprises the step of:

[0072] S200A, the cutting path at the head end and the tail end of each bevel cutting segment is extended, and intersection is formed with the cutting path of the adjacent bevel cutting segment.

[0073] Under normal circumstances, the cutting profile of the target workpiece is composed of a plurality of continuous bevel cutting segments, that is, each cutting profile is sequentially connected end to end. However, in the bevel machining process of the target workpiece, the machining path of part of the bevels will be offset based on the bevel angle and the thickness of the plate and the original cutting line segment, resulting in the situation that the head and tail of part of the bevel cutting segments cannot be connected.

[0074] By extending the cutting path at the head end and the tail end of each bevel cutting segment, and forming intersection with the cutting path of the adjacent bevel cutting segment, even if the machining path of part of the bevels is changed from the original cutting line, the situation that the head and tail of part of the bevel cutting segments cannot be connected due to incomplete cutting can also be avoided.

[0075] In further embodiments, please refer to Figure 6 , step S200A specifically comprises:

[0076] S210A, if the current groove cutting segment is a linear path, the groove cutting segment extends the cutting path in the linear direction at the head and tail ends, and forms an intersection with the cutting path of the adjacent groove cutting segment;

[0077] S220A, if the current groove cutting segment is a non-linear path, the groove cutting segment extends the cutting path in the tangent direction at the head and tail ends, and forms an intersection with the cutting path of the adjacent groove cutting segment.

[0078] In the judgment, the projection line segments of the upper surface profile line segment and the lower surface profile line segment of the current groove cutting segment of the target workpiece on the same plane can be obtained, and the projection line segment of the upper surface profile line segment or the projection line segment of the lower surface profile line segment is taken as the judgment basis, or the projection line segments of the upper surface profile line segment and the lower surface profile line segment are considered at the same time, and the above-mentioned extension mode is used to ensure complete cutting, so that all the groove cutting segments are connected in sequence.

[0079] In some embodiments, referring to Figure 7 , the groove cutting method further comprises the steps of:

[0080] S210B, setting the cutting priority of different types of conventional groove cutting segments and gradual groove cutting segments;

[0081] S220B, sorting the cutting sequence of each groove cutting segment.

[0082] The operator can set the cutting priority of different types of grooves according to the actual cutting environment of the workpiece, for example, the sorting priority is A-type groove cutting segment, I-type groove cutting segment, V-type groove cutting segment, and gradual groove cutting segment in sequence.

[0083] Specifically, the cutting software can assign corresponding profile numbers to each groove cutting instruction code segment in sequence after sorting, and form an independent cutting profile for each instruction code segment, and then combine the code forming the independent profile in sequence according to the profile number.

[0084] During cutting, the A-type groove cutting program instruction code can be executed first, then the I-type groove cutting program instruction code, then the V-type groove cutting program instruction code, and then the gradual groove cutting program instruction code, so as to reduce the adjustment steps of the cutting head and improve the overall cutting speed.

[0085] In further embodiments, referring to Figure 8 , the groove cutting method further comprises the steps of:

[0086] S210C, obtaining the coordinate value of the cutting starting point and the coordinate value of the cutting ending point of each groove cutting segment;

[0087] S220C, after the current groove cutting section is cut, the cutting head is controlled to jump to the cutting starting point of the next groove cutting section.

[0088] Since the cutting path of each groove cutting section is extended, and the cutting sequence of each groove cutting section is not performed in sequence, after each groove cutting section is cut, the cutting head can be controlled to jump to the cutting starting point of the next groove cutting section, so as to improve the cutting speed.

[0089] Specifically, the cutting software can perfect the device idle stroke code for each profile after combination, that is, the end coordinate value of the last profile number code after sorting combination and the first coordinate value of the next profile are obtained, and are respectively assigned to the idle stroke jump instruction and the instruction of the perforation and cutting layer.

[0090] In summary, the cutting software can complete the generation of the entire groove cutting program instruction NC of the target workpiece based on the above steps. When cutting the groove, the controller reads the NC instruction program in real time, obtains the angle between the laser cutting head and the normal of the workpiece plane to be processed from the program processing instruction, and sprays the cutting gas flow through the nozzle coaxially arranged with the cutting head, to assist the laser cutting head in cutting the groove.

[0091] Therefore, by dividing the cutting profile of the workpiece into a conventional groove cutting section and a gradually changing groove cutting section, the conventional groove cutting section can call other process parameters, and does not participate in the processing of the gradually changing groove cutting section. The related problems that the entire workpiece appears under the same cutting speed and the same cutting gas pressure in the existing gradually changing groove processing process are effectively solved, that is, the situation that the overall cutting quality consistency of the workpiece is poor or the overall processing speed is slow is improved, and a reasonable improvement method is proposed for the problem that the cutting paths do not intersect and are not completely cut off.
