It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 An embodiment of the multi-faceted diamond cutting method in the embodiment of the present invention includes:

[0028] 101. Confirm the actual working distance of the laser cutting head;

[0029] In this embodiment, a dual-station laser machine tool can be used to perform laser cutting on the roughcast to be processed to obtain the required multi-faceted diamond.

[0030] 102. Position and fix the blank to be processed according to the preset position requirements;

[0031] In this embodiment, a dual-station laser machine tool is used to achieve multi-faceted diamond cutting. The dual-station laser machine tool includes two stations arranged horizontally opposite to each other, each station includes a fixture rod, and the blank to be processed is clamped on the fixture rod. When the processing sequence is the first processing sequence, the placement of the blank to be processed follows the principle of processing the crown first and then the pavilion, that is, the pavilion of the blank to be processed is first fixed on any fixture rod.

[0032] 103. Obtain finished product effect drawings and finished product related parameters, generate pavilion section parameter data and crown section parameter data according to the finished product related parameters; and confirm the processing sequence of the laser cutting head, the processing sequence includes a first processing sequence and a second processing sequence;

[0033] In this embodiment, by generating pavilion section parameter data and crown section parameter data, the laser machine tool can perform cutting tasks stably and orderly according to the set parameters.

[0034] In this embodiment, the processing sequence can be input into the control system of the laser machine tool by the staff according to the placement of the blank to be processed; the first processing sequence is to process the crown first, then the waist, and finally the pavilion. Since the bonding position is located at the pavilion, the crown and the waist are processed first, and then the pavilion is further processed to ensure that the blank to be processed is effectively fixed on the jig rod during the cutting process, so as to avoid the displacement of the blank to be processed and affect the cutting effect of the laser machine tool on the blank to be processed.

[0035] In this embodiment, the second processing sequence is to process the pavilion first, then the waist, and finally the crown. At this time, the bonding position is located at the crown. By first processing the pavilion and the waist, and then further processing the crown, it is ensured that during the cutting process, the blank to be processed is effectively fixed on the fixture rod to avoid displacement of the blank to be processed and affect the cutting effect of the laser machine tool on the blank to be processed.

[0036] 104. When the processing sequence is the first processing sequence, an initial processing region of the crown is generated based on any crown facet of the crown from the finished product effect drawing, and after the processing of the initial processing region of the crown is completed, adjacent crown facets are processed one by one along a preset direction;

[0037] In this embodiment, starting from the initial processing area of ​​the crown, adjacent crown facets are processed successively along a preset direction. This processing method can effectively avoid the problem of laser interference between the processed surface and the surface to be processed, and can ensure that the laser beam acts on the surface to be processed in a stable and predictable manner, thereby improving the processing accuracy and reducing errors such as spot drift and shape distortion, so that the processing result is closer to the expected value.

[0038] 105. Process the waist according to the relevant parameters of the finished product. After the processing of the waist is completed, cut the pavilion bonding position, transfer the blank and complete the gluing of the crown bonding position.

[0039] 106. Generate an initial processing area for the pavilion based on any pavilion facet of the pavilion from the finished product effect drawing. After the processing of the initial processing area for the pavilion is completed, process adjacent pavilion facets one by one along a preset direction.

[0040] The present application discloses a multi-faceted diamond cutting method, which includes confirming the actual working distance of a laser cutting head; positioning and fixing a rough piece to be processed according to a preset position requirement; obtaining a finished product effect drawing and relevant parameters of the finished product, and generating pavilion section parameter data and crown section parameter data according to the relevant parameters of the finished product; and confirming the processing sequence of the laser cutting head; starting from the initial processing area of ​​the crown, processing adjacent crown facets one by one along a preset direction; processing the waist, and then transferring the rough piece between workstations; starting from the initial processing area of ​​the pavilion, processing adjacent pavilion facets one by one along a preset direction; the method disclosed in the present application uses a double-station laser machine tool to complete the cutting of the multi-faceted diamond rough piece, and has the advantages of high cutting efficiency, high cutting accuracy and stable cutting quality; and using the processing sequence and processing method disclosed in the present application to process the rough piece, it can ensure that the cutting process is carried out stably and orderly, and can avoid interference problems between the processed surface and the surface to be processed, thereby ensuring the surface quality of the finished product after cutting.

[0041] See also Figure 2 The second embodiment of the multi-faceted diamond cutting method in the embodiment of the present invention includes:

[0042] 201. Control the probe to move to the top of a fixture bar based on a preset probe moving speed and moving path, wherein the fixture bar is used to install the blank;

[0043] In this embodiment, the probe can be moved precisely in the Z-axis direction, and its position can be accurately read by the control system.

[0044] 202. Based on a preset probe descending speed, the probe is controlled to move downward to contact the fixture rod. When the probe feeds back a contact signal, the position of the probe is recorded and recorded as a Z-axis reference point;

[0045] In this embodiment, the probe descends relatively slowly to ensure that the position it contacts is the highest point on the surface of the fixture rod.

[0046] 203. Obtain the position information and processing requirements of the laser cutting head, and confirm the actual working distance of the laser cutting head according to the Z-axis reference point, the position information and processing requirements of the laser cutting head;

[0047] In this embodiment, the position information of the laser cutting head is the relative position of the cutting head in the machine coordinate system; the actual working distance is the distance between the cutting head and the surface of the blank to be processed, and the actual working distance = required processing depth + safety distance, wherein the required processing depth is the depth that the laser beam needs to penetrate the material, and the safety distance is an additional distance set to ensure that the laser beam does not directly contact the cutting head or other parts of the machine. The required processing depth and safety distance are confirmed by the processing requirements.

[0048] In this embodiment, before processing the blank, the jig rod is first installed on the fixture of the machine tool spindle, and the probe is controlled to first detect the highest point of the jig rod. After obtaining the z-axis data, the jig rod can be removed; when multiple blanks are processed multiple times in the subsequent process, there is no need to repeatedly use the probe to detect the z-axis data, that is, there is no need to repeat steps 201 to 203, because there is a positioning block on the jig rod, and each time it is installed, the installation height can be ensured to be consistent, that is, the Z-axis data can be ensured to remain unchanged; the actual working distance of the laser cutting head is adjusted according to the Z-axis data of the jig rod to ensure that the cutting head has the cutting ability, that is, to ensure the normal progress of the cutting task.

[0049] See also Figure 3 The third embodiment of the multi-faceted diamond cutting method in the embodiment of the present invention includes:

[0050] 301. Acquire a top real-time position image fed back by a camera located directly above the blank, a side real-time position image fed back by a camera located at the side of the blank, and a station real-time position image fed back by a camera located at the side of the station, wherein the station real-time position image records the real-time position information of two stations included in the dual-station laser machine tool;

[0051] In this embodiment, reference lines are pre-engraved on the blank, and the image captured by the camera device needs to ensure that the reference lines on the blank are clearly visible.

[0052] 302. Analyze whether the central axes of the two workstations are aligned according to the real-time position image of the workstations. If not, calculate the offset and generate a workstation adjustment plan.

[0053] In this embodiment, taking the workstation to which the blank is bonded as a reference, when the center axis of another workstation is not aligned with the center axis of the workstation to which the blank is bonded, that is, when the center axes of the two workstations are not coaxial, a laser measuring instrument is used to calculate the offset and the offset direction. When there are offsets in multiple directions, the total offset is calculated based on vector operations, and a workstation adjustment instruction is generated according to the calculated offset. The coaxial adjustment instruction is used to adjust the working state of the machine tool worktable, specifically, to adjust the position of the workstation to which the blank is not bonded, so as to achieve the purpose of correcting the offset.

[0054] The coaxiality of the two stations is adjusted through the real-time position image of the station to ensure that the axes of the two stations are on the same horizontal line, so as to ensure that the blanks after handover can remain coaxial and horizontal. There is no need to adjust the position of the blanks additionally, which greatly improves the work efficiency and ensures the processing effect and quality of the double-station laser machine tool for the processed blanks.

[0055] 303. Analyze whether the reference line on the blank is aligned with the center axis of the blank according to the real-time position image of the top. If not, calculate the offset and generate a coaxial adjustment plan.

[0056] In this embodiment, when the reference line on the blank is not aligned with the center axis of the blank, that is, when the reference line on the blank is not coaxial with the center axis of the blank, a laser measuring instrument is used to calculate the offset and the offset direction. When there are offsets in multiple directions, the total offset is calculated based on vector operations, and a coaxial adjustment instruction is generated based on the calculated offset. The coaxial adjustment instruction is used to adjust the machine tool worktable or adjust the working state of the mobile fixture to achieve the purpose of correcting the offset.

[0057] 304. Analyze whether the reference line on the blank is horizontal according to the real-time position image of the side. If it is not horizontal, calculate the angle and direction of inclination and generate a horizontal adjustment plan;

[0058] In this embodiment, when the reference line is not horizontal, that is, when the reference line is tilted relative to the image boundary, the angle of the tilt is calculated using trigonometric functions, and the direction of the tilt is determined using a direction identifier. Based on the measured tilt angle and direction, a horizontal adjustment instruction is generated. The horizontal adjustment instruction is used to adjust the tilt device of the machine tool or adjust the angle of the fixture to rotate or translate the blank.

[0059] 305. Positioning and fixing the workpiece to be processed according to the generated coaxial adjustment scheme and horizontal adjustment scheme;

[0060] In the actual processing process, the blank to be processed is first pre-bonded to any jig rod, and then a real-time image of the blank to be processed is obtained. The blank is adjusted to a horizontal and coaxial state according to the real-time image of the blank to be processed, and then glue is used to reinforce the bonding position between the blank and the jig rod, that is, the preset position is required to be perpendicular and coaxial to the horizontal ground.

[0061] See also Figure 4 The fourth embodiment of the multi-faceted diamond cutting method in the embodiment of the present invention includes:

[0062] 401. Obtaining a finished product effect drawing and finished product related parameters, wherein the finished product effect drawing is a finished product three-dimensional model, and the finished product related parameters include blank characteristics, girdle diameter, pavilion angle, crown angle, pavilion height, girdle height, and crown height;

[0063] In this embodiment, the finished product related parameters also include the C-axis rotation speed, which determines the speed of the diamond rotation during the laser cutting process; a higher rotation speed can improve production efficiency, but may also lead to a decrease in cutting quality because the laser beam spends less time on the material; conversely, a lower rotation speed can ensure better cutting quality but will reduce production efficiency.

[0064] 402. Generate pavilion section parameter data according to relevant parameters of the finished product, wherein the pavilion section parameter data includes pavilion cutting sequence, pavilion cutting speed, pavilion angle, pavilion Z-direction layer height and pavilion removal amount;

[0065] In this embodiment, the cutting operation speed refers to the moving speed of the laser beam during the cutting process. A faster cutting speed can improve production efficiency, but it may also lead to a decrease in cutting quality because the heating and cooling process of the laser beam on the material may not be sufficient. A slower cutting speed can ensure better cutting quality, but it will reduce production efficiency. The pavilion cutting speed is generated according to the material of the blank, the power of the laser and the surface quality requirements of the finished product.

[0066] In this embodiment, the pavilion angle corresponds to the pavilion angle in the finished product related parameters.

[0067] In this embodiment, the Z-direction layer height of the pavilion is related to the pavilion height and the cutting accuracy requirements; the Z-direction layer height refers to the distance that the laser beam moves each time along the Z-axis direction during the cutting process. A smaller layer height can improve the cutting accuracy, but will increase the total cutting time. Although a larger layer height can reduce the cutting time, it may reduce the cutting quality.

[0068] In this embodiment, the pavilion removal amount is determined according to the shape and size of the blank and the shape, size and weight of the finished product among the parameters related to the finished product.

[0069] 403. Generate crown section parameter data according to relevant parameters of the finished product, wherein the crown section parameter data includes crown cutting sequence, crown cutting speed, crown angle, crown Z-direction layer height, and crown removal amount;

After the processing of the crown initial processing area is completed, processing adjacent crown facets one by one along a preset direction, and generating a crown processing area corresponding to the crown facets and a crown processing path corresponding to the crown processing area.

[0077] In this embodiment, the preset direction may be in a clockwise direction or in a counterclockwise direction; further, the crown processing path corresponding to each crown processing area is consistent with the generation method of the crown initial processing path of the crown initial processing area.

[0078] Furthermore, in an embodiment of the present invention, the area of ​​the crown initial processing area and the area of ​​the crown processing area are both larger than the area of ​​the crown facet, ensuring that the coverage of the generated crown initial processing path and the crown processing path is larger than the area of ​​the crown facet, thereby ensuring that the laser cutting head can effectively cut the blank.
