[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] In order to solve the problem that in the actual use of the existing patent, due to the changes in the working environment and the disturbances in the processing process, the process selection of the tool set processing will be affected to a certain extent, thus making the planetary carrier tool set processing process defective and affecting the quality of the finished tool set, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0053] A multi-boss planet carrier cutter processing technology comprises the following steps:

[0054] S1: Acquire tool set processing technology knowledge through construction modules, build tool set processing technology case library based on the acquired tool set processing technology knowledge, and dynamically update the tool set processing technology case library, so as to change the processing technology according to the changes in the tool set processing environment and various disturbances, so as to avoid affecting the process during tool set processing and affecting the quality of tool set;

[0055] S2: Install the tool set to be processed at the processing location, obtain the tool set processing request and basic processing information, and quickly match the tool set processing process case by obtaining the tool set processing request and basic processing information;

[0056] S3: The tool set processing request and basic processing information are input into the tool set processing process case library through the process determination module, and the tool set dressing parameters are imported. By importing the tool set dressing parameters, the tool set can be trimmed according to the specific situation of the tool set processing process when matching the tool set processing process, thereby ensuring the effect of the tool set processing;

[0057] S4: querying whether a process case library contains similar processing cases of the current tool set processing process according to the input tool set processing request and basic processing information, and matching similar processing processes so that the tool set can be processed according to the processing process, thereby improving work efficiency;

[0058] S5: If there are similar processing cases, determine whether the parameters of the similar processing cases need to be modified, and modify the processing technology according to the tool set processing requirements. It can be applicable to different tool set processing, thereby improving practicality;

[0059] S6: If there is no similar processing case, rule reasoning is performed based on the process rule library to obtain process parameters and process sequence, and the multi-boss planetary carrier cutter set is processed according to the obtained process plan.

[0060] In step S1, a tool set processing technology case library is constructed, which specifically includes:

[0061] Obtain tooling process knowledge in tooling process decision-making from tooling process cases;

[0062] Structuring and hierarchical processing of tool set processing technology knowledge, and constructing a tool set processing technology domain knowledge model based on the processing of tool set processing technology knowledge;

[0063] The tool set processing technology knowledge in the tool set processing technology domain knowledge model is used to extract the tool set processing technology information from the tool set processing technology document;

[0064] The tool set processing technology information is expressed as a tool set processing technology case in a specified format to form a tool set processing technology case library.

[0065] By constructing a process domain knowledge model, the key concepts related to tool set processing in process decision-making, the attributes of the concepts and the relationship between the concepts are expressed, the multi-source heterogeneous process knowledge is structured, and the established tool set processing case library is updated to ensure that the tool set processing case library is in the latest state. As a result, the tool set will not be affected by changes in the working environment and various disturbances in the processing process, thereby ensuring the processing effect of the tool set.

[0066] The process information is expressed as process cases in a specified format to build a process case library, including:

[0067] Extract structured process information from process documents based on process knowledge provided by the process domain knowledge model;

[0068] Extract semi-structured process information and unstructured process information from process documents, and express the extracted process information in the form of the following process cases:

[0069] C = [B, T, N, Q];

[0070] Among them, B represents the tool set feature in processing, T represents the corresponding manufacturing resource status when making the tool set processing decision, N represents the processing chain corresponding to the tool set processing, and Q represents the process parameters of each step in the processing chain and the selected manufacturing resources.

[0071] A process domain knowledge model is extracted from various knowledge sources such as process manuals, process documents and expert experience based on ontology using a combination of top-down and bottom-up approaches. Specifically, after cleaning the knowledge in process manuals and expert experience, a top-down approach is used to obtain the top-level key concepts, attributes and relationships between concepts in production line process decisions from high-quality process knowledge sources. At the same time, a bottom-up approach is used to abstract process knowledge from process cases to supplement key concepts, attributes and relationships between concepts in the process.

[0072] In step S1, the tool set processing technology case library is dynamically updated, specifically including:

[0073] The real-time status of relevant elements of the tool set processing process is obtained through the collected multi-boss planetary carrier processing requirements;

[0074] Mapping the real-time status of the relevant elements of the tool set processing technology to the corresponding attributes of the corresponding instance in the process case library;

[0075] The real-time status of the relevant elements of the tool set processing technology is updated in real time to the corresponding attributes of the corresponding instances in the process case library according to the mapping relationship, so that the instances in the process case library are in the latest status.

[0076] Import tool set dressing parameters, including:

[0077] Determine the tool set dressing direction and type based on the multi-boss planet carrier;

[0078] According to the tool set dressing direction and dressing type of the multi-boss planetary carrier, set the cutting speed, feed amount and feed rate of the tool set;

[0079] According to the size of the multi-boss planet carrier cutter, the number of dressing times is set and the start time of each dressing time is determined.

[0080] By importing the tool set trimming parameters, the tool set processing parameters can be trimmed before tool set processing, which can improve the tool set processing efficiency and reduce the processing cost, thereby ensuring the quality of the tool set finished product. The settings of cutting speed, feed rate and feed speed can reasonably configure the tool set process, improve the tool set processing efficiency while ensuring the quality of the tool set cost.

[0081] The basic processing information includes process information items, material information items and size information. The tool set processing request includes cutting speed, feed amount and feed speed. The cutting speed Vc is 166m / min, the feed amount ap is 0.05mm, and the feed speed Fr is 0.065mm / r. By inputting the basic processing information and tool set processing request into the tool set processing process case library, the tool set processing process can be quickly identified, and then the tool set can be processed according to the tool set processing process case, which ensures the tool set processing effect and improves the tool set processing efficiency.

[0082] Check whether the process case library contains similar processing cases of the current tool set processing process, including:

[0083] Calculate the similarity between the target processing task and the existing cases in the process case library;

[0084] Based on various attributes of the target processing task, the existing process cases in the process case library are clustered;

[0085] Set a similarity threshold and calculate the similarity between the tool set processing task and the existing process cases based on the k-nearest neighbor algorithm;

[0086] The corresponding process cases whose calculated similarities are within the similarity threshold range are available similar processing process cases.

[0087] For new process cases, similarity calculation and comparative optimization should be carried out with the existing process plans in the process case library. The process case consists of processing tasks and process plans. The processing task attributes can be divided into character, numerical and fuzzy attributes. Corresponding to different similarity calculation methods, the weights of different types of attributes are determined based on the hierarchical analysis method and the principal component analysis method to obtain the similarity between processing tasks. After encoding the process route, the distance between the process plans is calculated based on the Euclidean distance to determine the similarity between the process plan and the existing process plans in the process case library.

[0088] Building blocks, including:

[0089] An acquisition module is used to acquire tool set processing technology knowledge in tool set processing technology decision from tool set processing technology cases;

[0090] The generation module is used to process the data acquired by the data acquisition module and generate a tool set processing technology case library based on the processed data.

[0091] Process determination module, including:

[0092] A process case retrieval module is used to retrieve the corresponding process case according to the input tool set processing request and basic processing information;

[0093] A judgment module is used to query whether the process case library contains similar processing process cases of the target processing task and make a judgment;

[0094] The process splitting module is used to generate a processing data set according to the corresponding process case, and generate a splitting process sequence for each processing data according to the processing data set.

[0095] By splitting the process cases, the process of each processing data can be adjusted according to the processing conditions of the tool set during the tool set processing, making the tool set processing technology more perfect and ensuring the quality of the tool set finished product.

[0096] The judgment module specifically includes:

[0097] A query module is used to query whether the process case library contains similar processing process cases of the target processing task according to the input tool set processing request and basic processing information;

[0098] The modification module is used to determine whether similar processing cases need to modify parameters based on the query results and make corresponding modifications based on the judgment results.

[0099] In summary, a multi-boss planetary carrier tool sleeve processing technology of the present invention can quickly identify the tool sleeve processing technology by inputting basic processing information and tool sleeve processing information into a tool sleeve processing technology case library, and then process the tool sleeve according to the tool sleeve processing technology case, thereby ensuring the tool sleeve processing effect and improving the tool sleeve processing efficiency. By constructing a process domain knowledge model, the key concepts related to tool sleeve processing in process decision-making, the attributes of the concepts and the relationship between the concepts are expressed, the multi-source heterogeneous process knowledge is structured, and the established tool sleeve processing technology case library is updated to ensure that the tool sleeve processing technology case library is in the latest state, so that the tool sleeve will not be affected by changes in the working environment and various disturbances in the processing process during processing, thereby ensuring the tool sleeve processing effect. By importing tool sleeve trimming parameters, the tool sleeve processing parameters can be trimmed before tool sleeve processing, thereby improving the tool sleeve processing efficiency and reducing the processing cost, thereby ensuring the quality of the finished tool sleeve. The settings of the cutting speed, feed rate and feed speed can reasonably configure the tool sleeve process, thereby improving the tool sleeve processing efficiency while ensuring the quality of the tool sleeve cost.
