[0030] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0031] The method for determining the free edge of a part grinded provided in the embodiment of the present application can be applied to Figure 1In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store data that server 104 needs to process and can be integrated with server 104, located in the cloud, or on another network server. Terminal 102 includes a device for collecting data on the part to be polished and a display device for displaying the target free edge results. Server 104 is used to determine the contour type of the part to be polished and determine the part type in the application scenario. Based on the multiple identified contours and target rules, it determines the initial free edge results for the part to be polished. Server 104 is also used to update the initial free edge results based on the part type to obtain the target free edge results. Server 104 can be the server at the blockchain end and can be implemented as a standalone server or a server cluster consisting of multiple servers. It can be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.

[0032] In one embodiment, Figure 2 As shown, a method for determining the free edge of a part is provided, and the method is applied to Figure 1 The server in the process includes the following steps:

[0033] Step 202 : determining the contour type of the part to be polished and determining the part type in the application scenario.

[0034] Target line segments in the contour type include straight lines, arcs, and circles; straight lines include target corner cuts, and arcs include target fillets. Part types include, but are not limited to, patch types, rib types, pad types, and panel types.

[0035] Specifically, if Figure 3 As shown, Figure 3 Schematic diagram of the process of determining the free edge for grinding parts. After obtaining the workpiece data of the part to be ground, the server determines the contour type of the part to be ground. Among them, the contour type can be divided into straight lines, arcs and circles according to the different target line segments. Since the functions of the parts to be ground are different in different application scenarios, the grinding requirements of the parts to be ground are also different, and the corresponding part type needs to be determined at this time. For example, in shipbuilding, patch plate type parts are often used to fill through holes or strengthen the hull structure. The outer periphery of the ship patch plate needs to be ground into a radius to ensure the painting effect; pad plate type parts are usually used in mechanical assembly to play a role in buffering, positioning or adjustment, etc. The grinding requirements are usually concentrated on the surface in contact with the mating parts.

[0036] In one embodiment, the contour type of the part to be polished is judged, including: when an arc contour is identified in the part to be polished, determining the original area of ​​the associated structure; constructing a new structure based on the endpoints of the arc, and determining the arc as the target fillet by the area of ​​the new structure and the original area; when two adjacent straight line contours are identified in the part to be polished, determining the target cutting angle by the two adjacent straight lines.

[0037] Specifically, when judging the contour type of the part to be polished, if the server determines that there is an arc contour in the target line segment, the endpoints of the arc are connected into a straight line and the straight line is used to replace the corresponding arc to construct a new structure. If the area of ​​the new structure is larger than the original area, the arc is called a fillet. Figure 4 The target fillet structure diagram is shown in the figure. When the server identifies two adjacent straight line contours in the part to be polished, if a middle straight line can be determined that intersects the two adjacent straight lines at a preset angle, and the adjacent straight lines are on the same side of the middle straight line and the middle straight line meets the preset length, then the middle straight line is determined to be the target corner cutting. The preset angle is, for example, within the range of 40-60 degrees, and the preset length is, for example, less than 20mm. Figure 5 Schematic diagram of the target cutting angle structure shown.

[0038] In this embodiment, by identifying arc and straight line contours within the part being ground, and combining area calculation with geometric construction, the target fillet and chamfer angles can be precisely determined, significantly improving grinding accuracy. Furthermore, by optimizing the shapes of fillets and chamfers, the structural performance of the part can be improved, facilitating subsequent grinding.

[0039] Step 204 : determining an initial free edge result in the part to be ground based on the identified multiple contours and target rules.

[0040] Specifically, refer to Figure 3 As shown, the server will summarize and generalize the target rules so that after the contour type judgment is performed, the free edge recognition will be performed according to the target rules, that is, according to the free edge type of the target fillet and the target chamfer, whether the target line segment is a free edge, whether the target line segment has been free edge judged, and at least one of the processing application scenarios of the target line segment, the free edge is preliminarily calculated from the multiple identified contours to obtain the initial free edge result in the part to be polished.

[0041] Step 206: Update the initial free edge result according to the part type to obtain the target free edge result.

[0042] Specifically, the server performs supplementary calculations on free edges based on part type. This primarily involves determining the contour features of the different types of parts to be polished, in order to implement supplementary and adjustment calculations based solely on target rules after free edge identification. In shipyards, patch-type parts, stiffener-type parts, and the like all have contour features of their own types, which include at least embedded contours, various circular contours, trapezoidal structural features, and rectangular structural features. For example, patch-type parts often have embedded contours, trapezoidal structural features, and the like; stiffener-type parts often have rectangular structural features, trapezoidal structural features, and the like. Therefore, the server will update the initial free edge results based on the different part types and their corresponding contour features to obtain the adjusted target free edge results.

[0043] In the above-mentioned method for determining the free edge of part grinding, by determining the contour type of the part to be ground and analyzing the application scenario, the initial free edge data of the part can be automatically extracted based on the part contour data. This data provides initial data support for the automatic grinding of the part. The initial free edge results are then updated according to different part types, achieving accurate supplementation and adjustment of the target free edge results. This achieves precise identification and automated grinding, reduces manual intervention, ensures grinding efficiency and accuracy, reduces defects and rework rates caused by improper grinding, and helps factories achieve automated production.

[0044] In one embodiment, an initial free edge result in a part to be ground is determined based on multiple identified contours and target rules, including: when the identified target fillet is a free edge to be ground, determining whether the first straight line is a free edge based on the tangency between the target fillet and the first straight line; when the first straight line is determined to be a free edge, determining a second straight line connected to the first straight line to be a non-free edge; when the identified target chamfer is a non-free edge, determining a third straight line connected to the target chamfer to be a non-free edge.

[0045] Specifically, when the server identifies that the target fillet is a free edge to be polished, the first straight line connected to the target fillet has the following two situations: if the first straight line is tangent to the target fillet or the angle between them is within a certain initial range, such as the initial range of 80-100 degrees, then this first straight line is a free edge; if the first straight line is not tangent to the target fillet, and the angle between them is outside the angle range defined by the initial range, then this first straight line is a non-free edge.

[0046] Furthermore, after the server determines that the first straight line is a free edge, if the line segment connected to the first straight line is a straight line type, the second straight line connected to the first straight line is a non-free edge. When the server identifies that the target corner cut is a non-free edge, it directly determines that the third straight line connected to the target corner cut is a non-free edge.

[0047] In this embodiment, by identifying the target fillet and target chamfer, and combining their tangent relationship with the adjacent straight lines, the type of line segment connected to the first straight line, the type of line segment connected to the target chamfer, etc., it is possible to accurately judge the free edges and non-free edges under different connection relationships, which can effectively avoid the subjectivity of manual judgment and improve the accuracy and efficiency of polishing.

[0048] In one embodiment, the above method also includes: when the target line segment in the contour type is both a free edge and a non-free edge, determining the target line segment as a non-free edge; when the target line segment in the contour type has not been judged as a free edge, determining the target line segment as a free edge; when the target line segment is a free edge to be polished, changing the target line segment to a non-free edge according to the actual processing application scenario.

[0049] Specifically, if the same target line segment in the contour type is both a free edge and a non-free edge during judgment, the server determines that the target line segment is a non-free edge to avoid excessive grinding. If a target line segment is neither judged as a free edge nor as a non-free edge during the judgment process, that is, when no free edge judgment is performed, the server determines that the target line segment is a free edge to ensure the integrity of the grinding. When the target line segment is an embedded contour, the server determines that all embedded contours are free edges. When the target line segment is a free edge to be ground, the target line segment is changed to a non-free edge according to the actual processing application scenarios such as the need for a bevel in the target line segment.

[0050] In this embodiment, by clarifying the free and non-free edge status of the target line segment, the grinding area can be precisely divided, thereby optimizing the grinding process. By adjusting the free edge determination based on different free edge conditions and actual machining application scenarios, the free edge can be flexibly adapted to different machining needs, further improving the targetedness and efficiency of grinding.

[0051] In one embodiment, the initial free edge result is updated according to the part type to obtain the target free edge result, including: when the part type is a patch type, determining the contour features of the part to be polished; under the initial free edge result, changing the line segments associated with the embedded contour to non-free edges; and changing the key line segments in the trapezoidal structure feature to non-free edges.

[0052] Among them, the part type includes the patch type, which represents the type used to fill or strengthen the structural part; the contour feature at least includes an embedded contour and a trapezoidal structural feature; the embedded contour includes multiple parallel straight lines and line segments between the parallel straight lines.

[0053] Specifically, for the patch type parts to be polished, some have embedded contours and trapezoidal structural features. Therefore, for the patch part, when the server calculates that it has an embedded contour, all the line segments associated with the embedded contour are judged as non-free edges. Figure 6As shown, Figure 6 A schematic diagram of a free edge update under the patch type, where the green lines are the non-free edges changed by the embedded contour.

[0054] In addition, when the server calculates that it has a trapezoidal structure feature, it can add parallel edge judgment. If two straight lines are parallel segments and the key segment of their angle is a straight line, and the parallel lines are on the same side of the key segment, the server will judge the key segment as a non-free edge. Figure 7 As shown, Figure 7 This is a schematic diagram of another free edge update under the patch type. The left side shows the initial free edge result similar to the trapezoidal structure, all of which are free edges with red lines, and the green lines on the right are the non-free edges after the change.

[0055] In this embodiment, by clearly defining the contour features of patch-type parts, it is possible to accurately distinguish between free and non-free edges. Defining line segments associated with embedded contours and key line segments within the trapezoidal structure as non-free edges avoids unnecessary machining of these critical structural areas during the polishing process. This not only improves polishing efficiency and reduces material waste, but also ensures the structural integrity and strength of the part, while providing a more precise geometric foundation for subsequent processing or assembly.

[0056] In one embodiment, the initial free edge result is updated according to the part type to obtain the target free edge result, including: when the part type is a reinforcement rib type, determining the contour features of the part to be polished; under the initial free edge result, using the two long side segments in the rectangular structure feature as free edges and the two short side segments as non-free edges; changing the key segments in the trapezoidal structure feature to non-free edges.

[0057] Among them, the part type includes the reinforcement rib type, and the reinforcement rib type represents the type attached to the part to enhance its rigidity and strength; the contour feature at least includes a rectangular structural feature and a trapezoidal structural feature.

[0058] Specifically, for the rib-type parts to be polished, some have rectangular structural features and trapezoidal structural features. Therefore, for the rib-type parts, when the server calculates that they have rectangular structural features, the two long side segments in the rectangular structural features are regarded as free edges, and the two short side segments are regarded as non-free edges. Figure 8 As shown, Figure 8 This is a schematic diagram of a free edge update for a rib type. The left side shows the initial free edge result for a rectangular structure, with all red lines representing free edges. The green lines on the right represent the modified non-free edges. Similarly, when the server calculates that the rib type has features similar to a trapezoidal structure, the specific process for changing the key segments in the trapezoidal structure to non-free edges is similar to the specific process for the patch type described above and will not be repeated here.

[0059] In this embodiment, by clearly defining the contour features of the ribbed part and accurately distinguishing between free and non-free edges, the grinding path can be optimized to avoid accidentally grinding critical structural parts. By defining the long sides of rectangular structures as free edges and the short sides as non-free edges, and by defining the key line segments of trapezoidal structures as non-free edges, the grinding process can be more accurately tailored to the actual needs of the part.

[0060] In one embodiment, the initial free edge result is updated according to the part type to obtain the target free edge result, including: when the part type is a pad type, determining that the contour features of the part to be polished include multiple circular contours; according to the actual processing application scenario, performing free edge changes on the circular contour under the initial free edge result; when the part type is a panel type, determining that the contour features of the part to be polished include rectangular structural features; under the initial free edge result, using the two long side segments in the rectangular structural feature as free edges and the two short side segments as non-free edges.

[0061] The part type includes at least a pad type and a panel type. The pad type represents the type of a plate-shaped part that supports or adjusts other parts, and the panel type represents the type of a plate component that constitutes a structural surface.

[0062] Specifically, for pad-type parts to be polished, some parts have circular or waist-round contour features. Therefore, for pad parts, when the server calculates that they have circular or waist-round contours, they can be judged as free edges or non-free edges based on the processing application scenario. Figure 9 As shown, Figure 9 This diagram shows the updated free edges for a pad type. The free edges under the circular outline on the left have been adjusted to non-free edges on the right. Furthermore, for panel-type parts to be polished, some have rectangular structural features. Therefore, the server can use the two long edge segments of the rectangular structural feature as free edges and the two short edge segments as non-free edges.

[0063] In this embodiment, the free edges of the circular contour of the backing plate can be flexibly adjusted to meet actual processing requirements, preventing accidental polishing of critical areas. For the panel, the long sides of the rectangular structure are designated as free edges, while the short sides are designated as non-free edges. This clear demarcation ensures that the polishing process is more consistent with the part's design requirements. This targeted polishing strategy not only improves polishing efficiency and quality, but also reduces material waste and the risk of rework caused by inaccurate polishing.

[0064] In one embodiment, the part type to be polished also includes a bracket type, which represents a type of connector connecting two or more components. When the part type is a bracket type, the existing free edge determined based on the target rule generally meets the actual requirements, and no additional contour feature determination is required. The server directly uses the initial free edge result as the target free edge result.

[0065] In one embodiment, the server can achieve semi-automatic grinding of parts by performing robot grinding teaching in advance.
