Abstract
Description
Technical Field
[0001] This application relates to the field of medical device manufacturing technology, and in particular to a method for generating CNC process schemes for oral implantation devices, an electronic device, and a computer-readable storage medium. Background Technology
[0002] Currently, dental instruments are divided into two categories: personalized and general-purpose. While some existing technologies have achieved the digitization of dental instruments, they are primarily designed for personalized dental instruments and are not suitable for the manufacturing of dental instruments. These technologies are less efficient when faced with relatively large-scale production.
[0003] General-purpose dental instruments are well-suited for mass production and require high efficiency. The machining of these instruments utilizes dedicated multi-functional CNC machine tools, capable of completing all machining processes in a single setup. The time spent in the entire manufacturing process includes not only the CNC machining itself but also the CNC programming.
[0004] Typically, for simple instruments, programming is straightforward, resulting in a shorter time spent on CNC program development. The relatively longer CNC machining process is generally overlooked. However, due to the small size and numerous steps involved in some dental instruments, process design and CNC programming time constitute a significant portion of the overall manufacturing time. Furthermore, dedicated CNC machine tools for dental instruments are already well-developed in terms of efficiency improvement; therefore, it is necessary to consider enhancing manufacturing efficiency from the process design and CNC programming stages. Summary of the Invention

[0007] On the other hand, this application provides an electronic device comprising: an identification unit that decomposes a target oral implant instrument part into a set of manufacturing features by constructing an attribute adjacency graph, decomposing convex edges, interpreting features, and extracting geometric information; a process template library unit that includes a main table and supplementary tables, the main table containing process information, station information, and process rules, and the supplementary tables containing machining method information and tool information; and a process generation unit that rapidly generates CNC process schemes through process template matching and process parameter calling.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0022] Please see Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the method for generating CNC manufacturing processes for dental implant device parts according to this application. The method includes the following steps:
[0023] S10: Input the target oral implant instrument part.
[0024] Specifically, the input target dental implant instrument part is a general-purpose instrument part that is highly suitable for mass production. The target dental implant instrument part is a general-purpose instrument part that can be categorized into a part family. Besides the target dental implant instrument part, it can also be an instrument part from general industrial, medical, or agricultural fields. In this embodiment, the target dental implant instrument part refers to an abutment or implant in the dental medical industry.
[0025] S20: Identify the manufacturing characteristics of the target oral implant instrument component.
[0026] Specifically, for abutments or implants, based on processing characteristics and geometric features, manufacturing features are categorized into features such as outer contour, holes, end faces, cavities, and chamfers.
[0027] Furthermore, the topological information of the abutment or implant is extracted to construct an attribute adjacency graph. Faces are used as graph nodes, the geometric edges between faces are graph edges, and information such as face type and concavity / convexity is used as node attributes, while information such as edge type and concavity / convexity is used as edge attributes. Concave subgraphs are searched within the attribute adjacency graph using convex edge decomposition to obtain a set of concave subgraphs.
[0028] Specifically, a concave pattern is obtained by decomposing convex edges, specifically referring to the recessed parts on a machine part, such as holes, to distinguish it from other surface features. The set of concave patterns refers to all concave patterns.
[0029] Finally, based on the definition of each type of manufacturing feature, the concave subgraphs are interpreted one by one to obtain the type to which the concave subgraph belongs, that is, to identify it as a manufacturing feature of that type.
[0030] S30: Extract the geometric parameters of the manufacturing features.
[0031] Specifically, based on the type of manufacturing feature, the geometric parameters of the manufacturing feature are extracted respectively. For example, for hole features, geometric information such as diameter and depth is extracted, and for cavity features, geometric information such as depth, area, and fillet radius is extracted.
[0032] S40: Decompose the target oral implant instrument part into a set of manufacturing features with geometric properties based on the manufacturing features and the geometric parameters of the manufacturing features.
[0033] Specifically, based on the manufacturing features obtained in step S20 and the geometric parameters of the manufacturing features obtained in step S30, the target oral implant device part is decomposed into a set of manufacturing features with geometric attributes. This process requires defining process rules to further extract more geometric attributes to distinguish the uncertain manufacturing features.
[0034] Specifically, process rules refer to the sum of feature types and feature parameters, which are used to distinguish different features.
[0035] Once the manufacturing feature type is identified, the corresponding geometric parameters can be extracted based on the feature type. For example, for hole features, geometric information such as diameter and depth can be extracted; for cavity features, geometric information such as depth, area, and fillet radius can be extracted. In this way, implant and other instrument parts are decomposed into a set of manufacturing features with geometric attributes.
[0036] S50: Match the set of manufacturing features with geometric properties with the data in the process template library to obtain the process template of the target oral implant device part.
[0037] Specifically, for the abutment or implant for which a CNC process plan is to be prepared, feature recognition is first performed to obtain manufacturing features and their geometric information; then, the process template type is selected based on the type of instrument part.
[0038] S60: Call the process parameters of the process template to generate a CNC process plan for oral implantation devices.
[0039] Specifically, the process of calling the process parameters of the process template to generate a CNC process plan for oral implant instruments includes: obtaining the operation and processing sequence of the instrument parts in the main table; then, selecting the manufacturing features on the abutment or implant to be programmed as the processing geometry according to the conditions of the process rules, and obtaining the process parameter information of the processing method and tool in the corresponding appendix table according to the processing method number and tool number; finally, constructing the processing operations of the abutment or implant to be programmed based on the processing geometry and process parameter information. After all processing operations are generated, the CNC process plan for the instrument parts is generated.
[0040] Please see Figure 2 , Figure 2 yes Figure 1 A flowchart illustrating step S20. In some embodiments, step S20 includes:
[0041] S22: The manufacturing features on the target oral implant instrument parts are divided into features including outer contour, holes, end faces, cavities and chamfers.
[0042] S24: Extract the topological information of the target oral implant instrument parts, construct an attribute adjacency graph, and find the concave subgraph in the attribute adjacency graph by decomposing the convex edges to obtain a set of concave subgraphs.
[0043] S26: Based on the definition of manufacturing features, each concave sub-diagram is interpreted to obtain the type to which the concave sub-diagram belongs, that is, to identify it as a manufacturing feature of that type.
[0044] Please see Figure 3 , Figure 3 This is a schematic flowchart of another embodiment of the method for generating CNC process solutions for oral implant device parts according to this application. In some embodiments, the method further includes the following steps before step "S10: Input target oral implant device part":
[0045] S100: Build a process template library.
[0046] Specifically, the process template library is mainly used for storing implant process template data and retrieving process template information. The process template library is built using a relational database, including a master table and supplementary tables.
[0047] The master table stores process information, workstation information, and process rules for abutment or implant instrument parts, including machining operation type, machining method number, tool number, group, manufacturing feature, and process rule conditions. The supplementary tables include machining method information and tool information. The machining method number and tool number in the master table correspond to the numbers in the machining method supplementary table and tool supplementary table, respectively. The group is related to the workstation. The process rule conditions are used for process template matching and store the attributes of the manufacturing features corresponding to the machining operation.
[0048] Process template information extraction involves parsing information from pre-compiled CNC process schemes for instrument part instances that represent a class of instrument parts. The specific parsing process is as follows: First, traverse the process tree associated with the abutment or implant instrument part instance to extract information such as machining operation type and cutting tools. Then, analyze manufacturing characteristics as conditions for process rules. Store this extracted information, along with the instrument part type, in a master table. The conditions for the process rules still need to be confirmed or modified by process engineers to ensure accurate matching of the process template. Finally, store cutting tool information in a cutting tool appendix and parameter information for each machining operation in the corresponding machining method appendix. Additionally, only key parameter information needs to be stored for machining operation information; not all parameter information needs to be stored.
[0049] S10: Input the target oral implant instrument part.
[0050] S20: Identify the manufacturing characteristics of the target oral implant instrument component.
[0051] S30: Extract the geometric parameters of the manufacturing features.

[0053] S50: Match the set of manufacturing features with geometric properties with the data in the process template library to obtain the process template of the target oral implant device part.
[0054] S60: Call the process parameters of the process template to generate a CNC process plan for oral implantation devices.

[0056] S102: Construct the process information of the machine parts, construct the workstation information of the machine parts, construct the process rule information of the machine parts; form the main table of the process template library.
[0057] Specifically, the master table stores process information, station information, and process rules for abutment or implant instrument parts, including processing operation type, processing method number, tool number, group, manufacturing feature, and process rule conditions. The group is related to the station. The process rule conditions are used for process template matching and store the attributes of the manufacturing features corresponding to the processing operation.
[0058] S104: Construct machining method information and tool information; generate a process template library appendix associated with the overall process template library table.
[0059] Specifically, the appendix includes machining method information and tool information. The machining method number and tool number in the main table correspond to the numbers in the machining method appendix and tool appendix, respectively.
[0060] S106: Complete the construction of the process template library.
[0061] Specifically, the process template library is constructed using a relational database, including a master table built in S102 and supplementary tables built in S104. The process template library is primarily used for storing implant process template data and retrieving process template information.
[0062] Please see Figure 5 , Figure 5 yes Figure 3 A flowchart illustrating step S50. In some embodiments, step S50 includes:
[0063] S52: Perform feature recognition on the target oral implant instrument parts to obtain manufacturing features and their geometric parameters.
[0064] Specifically, the system identifies manufacturing features such as the outer contour, holes, end faces, cavities, and chamfers on the target oral implant instrument parts. Based on the type of manufacturing feature, geometric parameters are extracted. For example, for hole features, geometric information such as diameter and depth is extracted; for cavity features, geometric information such as depth, area, and fillet radius is extracted.
[0065] S54: Determine the type of the target oral implant instrument component based on its manufacturing characteristics and geometric parameters.
[0066] Specifically, based on the manufacturing feature type identified by S52 and the geometric parameters of the acquired manufacturing feature, the type of the target oral implant instrument part is determined.
[0067] S56: Match the corresponding process template based on the type of the target oral implant instrument component.
[0068] Specifically, based on the type of the target oral implant instrument component determined by S54, the corresponding process template is matched.
[0069] Please see Figure 6 , Figure 6 yes Figure 3 A flowchart illustrating step S60. In some embodiments, step S60 includes:
[0070] S61: Based on the manufacturing characteristics of the target oral implant instrument part, obtain the process information, station information and processing sequence of the target oral implant instrument part from the main table of the process template.
[0071] Specifically, after determining the process template that matches the target oral implant instrument part, the process information, station information and processing sequence of each manufacturing feature on the target oral implant instrument part are obtained from the main table based on the manufacturing characteristics of the target oral implant instrument part.
[0072] S63: Select the manufacturing features on the target oral implant instrument part as the machining geometry based on the process rule conditions in the main table of the process template.
[0073] Specifically, machining geometry refers to the machining location of the manufacturing features of the target oral implant instrument part during the machining operation.
[0074] S65: Based on the machining method number and tool number in the main table of the process template, obtain the corresponding process parameter information of the machining method number and tool number in the corresponding supplementary table.
[0075] Specifically, the process information and processing method number are mapped to the manufacturing features of the target oral implant instrument part. Geometric information is extracted from the manufacturing features, and the process parameter information in the corresponding processing method table is extracted based on the processing method number and processing method.
[0076] S67: Construct the machining operation of the target oral implant instrument part based on machining geometry and process parameter information.
[0077] S69: Once all machining operations are generated, the CNC process plan for the target oral implant instrument part is obtained.
[0078] Please see Figure 7 , Figure 7 This is a schematic diagram of an embodiment of the electronic device of this application. The device can be used to implement the above-described method for generating CNC process schemes for oral implant instrument parts. The device 200 includes:
[0079] The identification unit 202 is used to identify the manufacturing feature type of the target oral implant instrument part by constructing an attribute adjacency graph, convex edge decomposition, feature interpretation, and geometric information extraction. Based on the type of manufacturing feature, it extracts the corresponding geometric parameters, such as diameter and depth for hole features, and depth, area, and fillet radius for cavity features. In this way, the implant and other instrument parts are decomposed into a set of manufacturing features with geometric attributes.
[0080] The process template unit 204 includes a process template library, which is mainly used for storing implant process template data and retrieving process template information.
[0081] The process template library includes a master table and supplementary tables. The master table stores process flow information such as operation type, machining method number, tool number, group, manufacturing feature, and process rule conditions for abutment or implant instrument parts. The supplementary tables include machining method information and tool information. The machining method number and tool number in the master table correspond to the numbers in the machining method supplementary table and the tool supplementary table, respectively. The group is related to the workstation. The process rule conditions are used for process template matching and store the attributes of the manufacturing features corresponding to the machining operations.
[0082] Process template information extraction involves parsing information from pre-compiled CNC process schemes for instrument part instances that represent a class of instrument parts. The specific parsing process is as follows: First, traverse the process tree associated with the abutment or implant instrument part instance to extract information such as machining operation type and cutting tools. Then, analyze manufacturing characteristics as conditions for process rules. Store this extracted information, along with the instrument part type, in a master table. The conditions for the process rules still need to be confirmed or modified by process engineers to ensure accurate matching of the process template. Finally, store cutting tool information in a cutting tool appendix and parameter information for each machining operation in the corresponding machining method appendix. Additionally, only key parameter information needs to be stored for machining operation information; not all parameter information needs to be stored.
[0083] The process generation unit 206 is used to quickly generate CNC process schemes for dental implant devices through process template matching and process parameter calling. It performs feature recognition on the target dental implant device part to obtain its manufacturing features and geometric parameters; determines the type of the target dental implant device part based on its manufacturing features and geometric parameters; and matches the corresponding process template based on the type of the target dental implant device part.
[0084] The process information, station information, and processing sequence of the instrument parts are obtained from the main table. Then, based on the conditions of the process rules, the manufacturing features on the target oral implant instrument parts for which the CNC process plan is to be prepared are selected as the machining geometry, and the process parameter information is obtained from the corresponding appendix table according to the machining method number and tool number. Finally, the machining operations of the target oral implant instrument parts for which the CNC process plan is to be prepared are constructed based on the machining geometry and process parameter information. After all machining operations are generated, the CNC process plan for the oral implant instrument is completed.
[0085] In one embodiment, the input is an example of an abutment-type part in an implant device. The steps of the method for generating the CNC process plan using the aforementioned electronic device 200 are as follows:
[0086] The process template information for the base platform includes: Part Type, Part Subtype, Machining Operation Subtype, Machining Operation Class, Machining Method Name, Machining Method ID, Tool ID, Working Group, corresponding manufacturing feature SubMachiningArea, and process rule condition IF. The base platform process template contains a total of 19 data entries, representing 19 machining operations. WorkingGroup indicates two working groups, and the Machining Method ID and Tool ID correspond to the numbers in the Machining Method Appendix and Tool Appendix, respectively.
[0087] Furthermore, the electronic device 200 identifies the manufacturing features of the base and displays the feature recognition results on the geometric feature tree. These features include six categories: Hole, Pocket, Profile, Chamfer, Endface, and ChamferO. Each category comprises one Hole feature, nine Pocket features, five Profile features, one Chamfer feature, three Endface features, and one ChamferO feature. The Hole feature extracts geometric parameters such as orientation (0, 1, 0), height (2.6 mm), and hole diameter (1.8 mm).
[0088] Finally, the base instance was matched with the base type data in the process template library, finding 19 data entries for the part type (PartType) and part subtype (PartSubType) that were bases. This base reused 19 machining operations. Further, based on the process rule condition (IF) in the main table, manufacturing features that met the conditions in the base feature recognition results were searched. The operation and machining method numbers were mapped to the manufacturing features of the base. Geometric information was extracted from the manufacturing features, and process parameter information from the corresponding machining method table in the appendix was extracted based on the machining method number and the machining method itself to generate machining operations. After all machining operations were generated, the CNC process plan for the base instance was obtained.
