[0002] This application claims priority to Chinese Patent Application No. 202411216772.9, filed on September 2, 2024, entitled "Method, Apparatus, Equipment and Storage Medium for Polyhedral Cutting of Machine Tools", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of laser processing technology, and in particular to methods, apparatus, equipment and storage media for polyhedral cutting of machine tools. Background Technology

[0004] Forming workpieces made of superhard materials (such as diamond (natural) and / or synthetic diamond) into products with the required complex shapes is very challenging, especially when high forming accuracy is required. For example, diamond (raw stone) is often made into complex shapes, including "round", "multifaceted", "cylindrical", "pear" or "princess" shapes, which have multiple facets that must be cut with very high accuracy.

[0005] Traditional methods for turning rough diamonds into faceted diamonds (or any other faceted gemstones) include cutting (e.g., cleaving, sawing, and / or grinding) and polishing. These two processes are often done by hand. In the manual processing, facets need to be created one by one, and each facet needs to be compared with the initial plan and adjusted based on the comparison results. This results in many processing steps, long processing time, and the fact that manual polishing is greatly affected by human factors, leading to inconsistent processing quality.

[0027] This application provides a method, apparatus, device, and storage medium for polyhedral cutting of machine tools. The terms "first," "second," "third," "fourth," etc. (if present)," in the specification, claims, and accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" or "having" and any variations thereof are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] For ease of understanding, the specific process of the embodiments of this application is described below. Please refer to Figure 1. One embodiment of the polyhedral cutting method of the machine tool in this application includes:

[0029] 101. Confirm the actual working distance of the laser cutting head;

[0030] In this embodiment, a single-station laser machine tool can be used to laser cut the blank to be processed in order to obtain the required polyhedron.

[0031] 102. Position and fix the blank to be processed according to the preset position requirements;

[0032] In this embodiment, a laser machine tool is used to perform polyhedral cutting. The laser machine tool includes a jig rod on which the blank is clamped. For the diamond blank to be processed, in one embodiment, it can be fixed to the jig rod with the pavilion facing upwards and the crown facing downwards. Since the bonding position is located at the crown, the pavilion and girdle can be processed first, and then the crown can be further processed to ensure that the blank is effectively fixed to the jig rod during the cutting process, avoiding displacement of the blank and affecting the cutting effect. Specifically, the blank is first pre-bonded to the jig rod, and the pre-bonded blank is basically perpendicular to the horizontal ground. Then, a real-time position image of the blank is obtained, and the blank is adjusted to a horizontal and coaxial state according to the real-time position image. Then, glue is used to reinforce the bonding position between the blank and the jig rod, that is, the preset position requirement is to be perpendicular to the horizontal ground and coaxial.

[0033] 103. Obtain the finished product rendering drawings and related parameters, and generate the cross-sectional parameters based on the finished product parameters;

[0034] In this embodiment, for a diamond polyhedron, the facet parameters include pavilion facet parameter data and crown facet parameter data. By generating pavilion facet parameter data and crown facet parameter data, the laser machine tool can stably and orderly perform the cutting task according to the set parameters.

[0035] 104. From the finished product drawing, generate an initial processing area based on any facet. After the initial processing area is completed, process the adjacent facets one by one along the preset direction until all facets are processed.

[0036] In this embodiment, starting from the initial processing area, the adjacent pavilion facets are processed sequentially 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.

[0037] This application discloses a method for polyhedral cutting using a machine tool. The method involves confirming the actual working distance of the laser cutting head; positioning and fixing the workpiece according to preset position requirements; obtaining finished product renderings and related parameters; generating cutting parameters based on these parameters; generating an initial processing area from any facet of the finished product renderings; and, after completing the initial processing area, processing adjacent facets sequentially along a preset direction until all facets are processed. The method disclosed in this application uses a laser machine tool to cut polyhedrals, offering advantages such as high cutting efficiency, high cutting precision, and stable cutting quality. Furthermore, using the processing method disclosed in this application to process the workpiece ensures a stable and orderly cutting process and avoids interference between the processed surface and the surface to be processed, thus ensuring the surface quality of the finished product after cutting.

[0038] Please refer to Figure 2. A second embodiment of the polyhedral cutting method for machine tools in this application includes:

[0039] 201. Based on a preset probe moving speed and moving path, the probe is controlled to move above the jig bar, which is used to clamp the blank;

[0040] In this embodiment, the probe can move precisely in the Z-axis direction, and its position can be accurately read by the control system.

[0041] 202. Based on the preset probe descent speed, control the probe to move downward to contact the jig rod. When the probe returns a contact signal, record the position of the probe and mark it as the Z-axis reference point.

[0042] In this embodiment, the probe descends relatively slowly to ensure that it contacts the highest point of the jig rod surface.

[0043] 203. Obtain the position information and processing requirements of the laser cutting head, and confirm the actual working distance of the laser cutting head based on the Z-axis reference point, the position information of the laser cutting head, and the processing requirements;

[0044] 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. The actual working distance = required processing depth + safety distance. The required processing depth is the depth to which the laser beam needs to penetrate the material. 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 determined by the processing requirements.

[0045] In this embodiment, before processing the blank, the jig bar is placed on the fixture of the machine tool spindle. The probe is controlled to first detect the highest point of the jig bar and obtain the Z-axis data. Then, the jig bar can be removed. When processing multiple blanks in a subsequent process, it is not necessary to repeatedly use the probe to detect the Z-axis data, that is, it is not necessary to repeat steps 201 to 203, because there are positioning blocks on the jig bar. Each time it is installed, the installation height can be kept consistent, that is, the Z-axis data remains unchanged. Adjusting the actual working distance of the laser cutting head according to the Z-axis data of the jig bar can ensure that the cutting head has cutting capability, that is, ensure that the cutting task is carried out normally.

[0046] Please refer to Figure 3. The third embodiment of the polyhedral cutting method for machine tools in this application includes:

[0047] 301. After the installation of the blank is completed, obtain the real-time top position image fed back by the camera device located directly above the blank, and obtain the real-time side position image fed back by the camera device located on the side of the blank.

[0048] In this embodiment, reference lines are pre-etched on the blank, and the image captured by the camera device needs to ensure that the reference lines on the blank are clearly visible.

[0049] 302. Based on the real-time position image at the top, analyze whether the reference line on the blank is horizontal. If it is not horizontal, calculate the angle and direction of tilt and generate a horizontal adjustment plan.

[0050] 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 tilt is calculated using trigonometric functions, and the direction of tilt is determined using a direction identifier. Based on the measured tilt angle and direction, a horizontal adjustment command is generated. The horizontal adjustment command is used to adjust the tilting device of the machine tool or the angle of the fixture to rotate or translate the blank.

[0051] 303. Based on the real-time position image of the side, analyze whether the reference line on the blank is aligned with the center axis of the blank. If they are not aligned, calculate the offset and generate a coaxial adjustment scheme.

[0052] In this embodiment, when the reference line is not aligned with the center axis of the blank, that is, when the reference line is not coaxial with the center axis of the blank, a laser measuring instrument is used to calculate the offset and offset direction. When there are offsets in multiple directions, the total offset is calculated based on vector operation. A coaxial adjustment command is generated according to the calculated offset. The coaxial adjustment command is used to adjust the working state of the machine tool table or the moving fixture to achieve the purpose of correcting the offset.

[0053] 304. Based on the generated horizontal adjustment scheme and coaxial adjustment scheme, position and fix the blank to be processed.

[0054] Please refer to Figure 4. The fourth embodiment of the polyhedral cutting method for machine tools in this application includes:

[0055] 401. Obtain finished product rendering drawings and related parameters. The finished product rendering drawings are three-dimensional models of the finished product. The related parameters include blank characteristics, waist diameter, pavilion angle, crown angle, pavilion height, waist height, and crown height.

[0056] In this embodiment, the finished product-related parameters also include the C-axis rotation speed, which determines how fast the diamond rotates 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 stays on the material for a shorter time. Conversely, a lower rotation speed can ensure better cutting quality, but will reduce production efficiency.

[0057] 402. Generate cross-sectional parameters based on the relevant parameters of the finished product. The cross-sectional parameters include pavilion cross-sectional parameter data and crown cross-sectional parameter data. The pavilion cross-sectional parameter data includes pavilion cutting sequence, pavilion cutting speed, pavilion angle, pavilion Z-axis layering height, and pavilion removal amount. The crown cross-sectional parameter data includes crown cutting sequence, crown cutting speed, crown angle, crown Z-axis layering height, and crown removal amount.

[0058] In this embodiment, the cutting speed refers to the speed at which the laser beam moves during the cutting process. A faster cutting speed can improve production efficiency, but may also lead to a decrease in cutting quality because the heating and cooling process of the laser beam on the material may be insufficient. A slower cutting speed can ensure better cutting quality, but will reduce production efficiency. The pavilion cutting speed is generated based on the material of the blank, the power of the laser, and the surface quality requirements of the finished product.

[0059] In this embodiment, the pavilion angle corresponds to the pavilion angle in the relevant parameters of the finished product.

[0060] In this embodiment, the Z-axis layering height of the pavilion is related to the pavilion height and the cutting accuracy requirements. The Z-axis layering height refers to the distance the laser beam moves along the Z-axis each time during the cutting process. A smaller layering height can improve cutting accuracy, but will increase the total cutting time. A larger layering height can reduce cutting time, but may reduce cutting quality.

[0061] In this embodiment, the amount of material removed from the pavilion is determined based on the shape and size of the blank to be processed and the requirements of the shape, size and weight of the finished product in the relevant parameters of the finished product.

[0062] In this embodiment, the crown cutting speed is generated based on the material of the blank, the power of the laser, and the surface quality requirements of the finished product; the crown angle corresponds to the crown angle in the relevant parameters of the finished product; the crown Z-axis layering height is related to the crown height and the cutting accuracy requirements; furthermore, the crown removal amount is determined based on the shape and size of the blank to be processed and the shape, size, and weight of the finished product in the relevant parameters of the finished product.

[0063] Furthermore, when the blank to be processed is a diamond blank, the relevant parameters of the finished product also include the waist diameter and waist height. After the pavilion part of the blank to be processed is completed, the waist of the blank to be processed is processed based on the waist diameter and waist height.

[0064] Please refer to Figure 5. The fifth embodiment of the polyhedral cutting method for machine tools in this application includes:

[0065] 501. The finished product rendering includes a pavilion, a waist, and a crown. From the finished product rendering, an initial processing area for the pavilion is generated based on any facet of the pavilion.

[0066] In this embodiment, the initial processing area and the processing area of ​​the pavilion can be rectangular areas.

[0067] 502. On the initial processing area of ​​the pavilion, generate a first initial path along the direction from the pavilion to the crown. Take any end of the first initial path as the initial processing point of the pavilion, connect the other end of the first initial path, and generate a first remaining path in a bow shape. Integrate the first initial path and the first remaining path to obtain the initial processing path of the pavilion corresponding to the initial processing area of ​​the pavilion.

[0068] In this embodiment, the specific location and boundary of the initial processing area of ​​the pavilion are first determined. Then, the processing software is used to draw the first initial path, which is a straight line with a length greater than the length of the corresponding facet. Then, the first remaining path is generated along the bow-shaped path. The overall initial processing path of the pavilion is bow-shaped. Finally, the initial processing path of the pavilion is further optimized by the optimization tool to reduce empty travel, avoid sharp turns or repeated processing, and achieve the purpose of reducing processing time and improving processing efficiency.

[0069] In this embodiment, both the initial processing path and the processing path of the pavilion are cut from the side of the pavilion facet, which can further avoid laser interference between the processed surface and the surface to be processed, and improve the surface quality of the finished product.

[0070] 503. Based on the initial processing path of the pavilion, process the initial processing area of ​​the pavilion. After the processing of the initial processing area of ​​the pavilion is completed, process the adjacent pavilion facets one by one along the preset direction, and generate the pavilion processing area corresponding to the pavilion facets, as well as the pavilion processing path corresponding to the pavilion processing area.

[0071] In this embodiment, the preset direction can be either clockwise or counterclockwise; furthermore, the method for generating the processing path of each pavilion processing area is consistent with the method for generating the initial processing path of the initial processing area of ​​the pavilion.

[0072] Please refer to Figure 6. The sixth embodiment of the polyhedral cutting method for machine tools in this application includes:

[0073] 601. From the finished product drawing, generate the initial processing area of ​​the crown based on any crown facet;

[0074] In this embodiment, the initial processing area of ​​the crown and the processing area of ​​the crown can be rectangular areas.

[0075] 602. On the initial processing area of ​​the crown, generate a second initial path along the direction from the crown to the pavilion. Take any end of the second initial path as the initial processing point of the crown, connect the other end of the second initial path, and generate a second remaining path in a bow shape. Integrate the second initial path and the second remaining path to obtain the initial processing path of the crown corresponding to the initial processing area of ​​the crown.

[0076] In this embodiment, the specific location and boundary of the initial processing area of ​​the crown are first determined. Then, a second initial path is drawn using processing software. The second initial path is a straight line with a length greater than the length of the corresponding facet. Then, a second residual path is generated along the bow-shaped path. The overall initial processing path of the crown is bow-shaped. Finally, the initial processing path of the crown is further optimized using optimization tools.

[0077] 603. Based on the initial processing path of the crown, process the initial processing area of ​​the crown. After the processing of the initial processing area of ​​the crown is completed, process the adjacent crown facets one by one along the preset direction, and generate the crown processing area corresponding to the crown facet and the crown processing path corresponding to the crown processing area.

[0078] In this embodiment, the preset direction can be either clockwise or counterclockwise; furthermore, the crown processing path corresponding to each crown processing area is generated in the same way as the crown initial processing path of the crown initial processing area.

[0079] Furthermore, in this embodiment, the area of ​​the initial processing area of ​​the pavilion and the area of ​​the processing area of ​​the pavilion are both larger than the area of ​​the pavilion facet, ensuring that the coverage of the generated initial processing path and the processing path of the pavilion is larger than the area of ​​the pavilion facet, thereby ensuring that the laser cutting head can effectively cut the blank.

[0080] Furthermore, in this embodiment, the area of ​​the initial processing area of ​​the crown 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 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.
