[0027] In a first aspect, as shown in the drawings, the application provides a centralized management method of machine tool machining tools, comprising the following steps: Figure 1 The centralized management method of machine tool machining tools comprises the following steps: Step S1: acquiring measurement data of the tool and writing the measurement data to the electronic tag of the tool; Step S2: creating a central management system database comprising a central tool magazine data table, a product tool scheme table, a machine tool tool magazine tool arrangement table, a machine tool tool list table and a tool history table according to tool initialization data; Step S3: according to the model of the workpiece to be machined, the corresponding tool scheme is called from the central management system database, the tool list of the current machine tool tool magazine is acquired, the tool changing requirements of each tool position are calculated, and the tool changing operation is performed according to the tool changing requirements of each tool position. After tool changing, the data of the central management system database is updated; Step S4: Based on the current processing workpiece type, cutting time and processing quantity, the estimated result of the remaining life of the current processing tool is obtained and its electronic tag is updated, and a tool updating reminder information is sent when the remaining life reaches the life threshold.

[0028] The present application realizes precise tracking and intelligent management and control of the whole life cycle of the tool through the cooperative management of the electronic tag and the central database, improves the automation level of tool management, and effectively avoids errors and low efficiency problems caused by manual recording; By establishing a multi-dimensional associated database system, intelligent matching and automatic optimization of processing scheme and tool configuration are realized. This method ensures the standardization and consistency of tool use, greatly reduces the abnormal production situation caused by tool mixing; The dynamic life monitoring mechanism based on real-time processing data makes tool replacement more scientific and reasonable, which not only avoids the influence of tool overconsumption on processing quality, but also optimizes the use efficiency of tool resources and reduces production cost; By mining the value of historical data, continuously optimizing processing parameters, and significantly improving production efficiency and product quality stability.

[0029] In an embodiment, the step S1 of obtaining the measurement data of the tool and writing the measurement data to the electronic tag of the tool comprises the following steps: The tool information initialization operation is specifically implemented as follows: Step S11: Obtain the measurement data of the new tool, which includes length, diameter and blade angle data; specifically, place the new tool on the tool pre-adjustment instrument and measure its geometric parameters (such as length, diameter, blade angle, etc.); Step S12: Write the measurement results and tool information (such as unique identification, model, expected life) to the electronic tag of the tool. The tool After the tool information initialization operation is performed, the tool is stored in the central tool magazine and re-registered in the central management system.

[0030] Based on steps S11 and S12, the tool geometric parameters are accurately measured by the pre-adjustment instrument and written to the electronic tag, realizing automatic acquisition and digital storage of tool basic data, effectively solving the problems of low efficiency and easy error in traditional manual measurement, and providing accurate data basis for subsequent intelligent management and control.

[0031] In an embodiment, the step S2 of creating a central management system database including a central tool magazine data table, a product tool scheme table, a machine tool tool magazine tool arrangement table, a machine tool tool list table and a tool history table according to the tool initialization data comprises the following steps: Step S21: synchronize the unique identification, model, geometric parameters and expected life information of all tools in the central tool magazine, record the current storage level and position number of each tool, and generate a central tool magazine data table; Step S22: map the product model to the tool scheme one by one, establish the mapping relationship between the product model and the required tool scheme, define the corresponding tool type, quantity and process parameters for each product machining, and form a product tool scheme table; Step S23: configure the tool arrangement scheme of the fixed tool position for each machine tool, and assign the corresponding tool of the processable product to the specified tool position of the machine tool magazine; specifically, arrange the tools corresponding to all processable products of the machine tool on the machine tool magazine, and assign one tool position of the machine tool magazine to one type of tool, to generate a machine tool magazine tool arrangement table; Step S24: collect the unique identification, model and actual tool compensation data of each tool position in the current tool magazine of each machine tool, and dynamically maintain a machine tool list table; Step S25: record the use history data of each tool with the tool unique identification as the index, and construct a tool history table, such as the last measurement data, the machine tool object, and the machining object.

[0032] The present application realizes systematic management and precise control of the whole life cycle of the tool by constructing a central management system database. The central tool magazine data table archives the basic information and storage position of the tool, providing core data support for tool scheduling; the product tool scheme table establishes the standardized mapping relationship between the product and the tool, ensuring the standardization and traceability of the machining process. The machine tool magazine tool arrangement table optimizes the tool changing efficiency of the machine tool and reduces the risk of human error by predefining the fixed matching of the tool type and the tool position; The machine tool list table dynamically maintained in real time reflects the actual configuration state of the tool of each machine tool, providing accurate basis for production scheduling; the tool history table completely records the machining track and state evolution of the tool, supporting tool performance degradation analysis and providing data basis for tool maintenance and life prediction. The whole database architecture improves the tool resource utilization rate, machining process stability and production management refinement level through multi-dimensional data linkage.

[0033] In an embodiment, the step S3 comprises the following steps: Step S31: According to the model of the workpiece being processed, the corresponding tool configuration scheme is retrieved from the central management system database, the tool list of the current machine tool tool magazine is obtained, the tool configuration scheme is compared with the tool magazine list, and the replacement requirements of each tool position are determined. Further, when determining the replacement requirements of each tool position, the central management system first retrieves the standard tool configuration scheme corresponding to the product from the database according to the model of the workpiece being processed, and clearly determines the type and quantity of tools required to complete the processing of the workpiece. Then the system obtains the actual tool list of the current machine tool tool magazine, and compares the two items by item. For each tool position, the system checks whether the currently stored tool is consistent with the standard configuration scheme requirement. If it is not consistent, the tool position is marked as needing replacement. More specifically, if the current tool type of a tool position does not match the standard configuration, or the current tool life has been exhausted, the system will generate a replacement instruction. If the tool position is currently empty but the standard configuration requires a tool to be placed, a tool supplement instruction is generated. If the tool position currently has a tool but the standard configuration does not require it, a tool removal instruction is generated. The system will comprehensively consider factors such as tool type matching, life status, and processing priority, and finally generate a replacement requirement list containing all tool positions that need to be changed and the corresponding new tool information. The list clearly indicates the specific operation content (retention, replacement, supplement, or removal) of each tool position, providing accurate guidance for the subsequent automatic tool changing process. Step S32: According to the replacement requirements of each tool position, the required tools are retrieved one by one and their information is verified, the tool replacement operation is performed, and the tool data of the replaced tools is updated synchronously. Specifically, when implementing the tool replacement operation, the system will retrieve the corresponding tools from the central tool magazine one by one according to the previously calculated replacement requirements of each tool position. Each tool needs to be scanned and confirmed by a tag reader when it is taken out, to ensure that the tool information matches the requirement list completely. After confirmation, the tool is placed on a temporary storage tray, and the central management system is fed back the status information that the tool has been taken out. After all the required tools have been verified and taken out, the tool taking / placing device transports these tools to the target machine tool in batches. At the machine tool end, the operator or automatic equipment first unloads the old tools that need to be replaced from the machine tool tool magazine one by one, and confirms the identity of the old tools through the tag reader on the machine tool. Then, the verified new tools are loaded into the machine tool tool magazine according to the predetermined tool position number. After completing the tool changing operation for each tool position, the central management system immediately sends the key information of the new tool, such as the geometric parameters and tool compensation data, to the machine tool numerical control system, and updates the tool list of the machine tool in real time. At the same time, the replaced old tools are sent to the tool pre-adjustment instrument for geometric parameter measurement, and the wear state and remaining life data are updated. Finally, the old tools are re-stored in the central tool magazine and the inventory information is updated. The entire tool changing process realizes closed-loop management of tool data, ensuring the real-time and accuracy of tool information.

[0034] Step S33: measuring the parameters of the original tool after replacement, calculating the remaining life based on the measurement results and updating the tool information, re-storing the original tool and recording its state; specifically, when measuring the parameters of the original tool after replacement, first accurately measure the geometric parameters (such as length, diameter, edge angle, etc.) of the tool through the tool pre-adjustment instrument, and upload the measurement results to the central management system. The central management system re-estimates the remaining life of the tool according to the current machining workpiece type, cutting time and machining quantity, combined with the measurement data. Then, the system writes the updated life information into the electronic tag of the tool through the tag reader and writer, and records the wear condition and current state of the tool. If the remaining life of the tool still meets the use requirements, it is re-stored in the designated position of the central tool library, and the storage level and position information are updated in the central management system; if the tool life has reached or approached the preset threshold, the system automatically marks it as to be replaced or unusable, and recommends a replacement tool solution. After all operations are completed, the central management system synchronously updates the tool historical data table, records the measurement results, remaining life and storage state, and provides data support for subsequent tool scheduling and quality analysis; Step S34: synchronously updating the latest state and position information of all tools after replacement in the central management system database; specifically, after completing the tool replacement operation, the central management system needs to update the tool state in real time. The system first automatically corrects the inventory account of the central tool library according to the tool flow record feedback by the tool taking / placing device, accurately records the current level and position information of each tool. For the newly loaded tool in the machine tool library, the system will mark its state as "in use", and associate the corresponding machine number, tool position number and current machining task information; at the same time, the state of the replaced old tool is changed to "to be checked", and the last measurement data before returning to the central tool library is recorded. The system also updates the tool life database, adds the wear amount generated by this machining to the tool historical use data, and re-calculates the remaining life value. All changes will be refreshed in real time through the visual interface to ensure that the data of the central tool library three-dimensional inventory model, machine tool tool list, tool history file, etc. remain synchronized and consistent. In addition, the system automatically generates a tool transaction log, which details the tool replacement time, operator, tool serial number and other traceability information, providing a complete data chain for subsequent quality analysis.

[0035] In an embodiment, the step S4: based on the current machining workpiece type, cutting time and machining quantity, obtaining the estimated result of the remaining life of the current machining tool and updating its electronic tag, and sending a tool update reminder information when the remaining life reaches the life threshold, specifically includes the following steps: Step S41: match the preset tool wear coefficient according to the current workpiece type, and calculate the cumulative wear amount combined with the real-time collected cutting time; specifically, according to the current workpiece type, the preset tool wear coefficient is matched, and the cumulative wear amount is calculated combined with the real-time collected cutting time, specifically including: calling the product process database through the central management system to obtain the current workpiece material characteristics, processing procedure characteristics and historical processing data, and extracting the standard wear coefficient curve of the corresponding tool; real-time monitoring of spindle load, vibration signal and cutting temperature in the processing process, dynamically correcting the theoretical wear coefficient; based on the difference between the initial geometric parameters recorded by the tool electronic tag and the current parameters measured by the machine tool setting instrument, a mapping relationship between the actual wear amount and the theoretical calculation value is established; the cutting time is segmented and accumulated according to the processing stage, and is multiplied by the dynamic wear coefficient of the corresponding stage, and finally a cumulative wear amount model considering material characteristics, working condition parameters and actual wear state is generated; Step S42: real-time comparison of cumulative wear amount and tool life threshold, generating residual life data and writing into electronic tag; specifically, when comparing the cumulative wear amount and the tool life threshold in real time, the system dynamically calculates the actual wear increment by collecting the cutting parameters (such as feed rate, speed, cutting depth) of the current workpiece and the processing time, combined with the preset tool wear coefficient model. After superimposing the new wear amount and the historical cumulative value, compare it with the life threshold stored in the electronic tag to generate a residual life percentage value. This value is updated to the life information field of the tool electronic tag through the tag reader / writer in real time, and is also synchronized to the tool history table of the central management system. When the residual life is lower than the preset warning threshold (such as 20%), the system updates the tag data at the same time and triggers the warning flag, providing real-time data basis for subsequent replacement decision. During the comparison process, the system will check the rationality of the wear data. If an abnormal mutation (such as the single wear amount exceeding 150% of the theoretical value) is detected, the manual review process is started and the automatic update mechanism is frozen.

[0036] Step S43: triggering a warning signal when the remaining life is lower than the life threshold, generating a replacement notification containing the tool identification and recommended replacement tool model; specifically, when the tool remaining life is lower than the preset threshold, the system automatically triggers the warning mechanism. The central management system identifies the tool unique identification through the electronic tag, retrieves the database to obtain the tool model specifications, historical use data and current processing task information. The system matches the central tool library inventory information according to the tool model, and preferentially recommends the same model spare tool; if there is no inventory, it recommends alternative models according to the tool parameter similarity, and considers the precision requirements of the current workpiece. The replacement notification is displayed in real time through the human-machine interface and pushed to the relevant equipment terminal, and the notification content includes tool position information, remaining life percentage, and recommended replacement scheme technical parameter comparison. For the tools used in key processes, the system will trigger the production scheduling module simultaneously, prompting the process personnel to review the applicability of the replacement tool. The warning information is also written into the tool history record table, providing a basis for subsequent quality traceability.

[0037] Based on steps S41-S43, by monitoring the tool wear condition in real time and dynamically updating the remaining life information, the system can effectively avoid the problems of processing quality decline or equipment damage caused by excessive tool wear. Based on the comprehensive life estimation method of workpiece type, cutting time and processing quantity, the accuracy of tool state determination is improved, ensuring that the tool replacement is carried out at the best time, reducing the unplanned downtime. The automatic life warning mechanism can plan the tool replacement in advance, optimize the production scheduling, and at the same time avoid the increase of scrap rate caused by tool failure. The real-time updating function of the electronic tag ensures the synchronization and traceability of the tool state information, providing a reliable basis for tool management and maintenance decision-making.

[0038] In an embodiment, the step S4: based on the current processing workpiece type, cutting time and processing quantity, obtaining the estimation result of the remaining life of the current processing tool and updating its electronic tag, after sending the tool update reminder information when the remaining life reaches the life threshold, further comprises the following steps: Step S5: generating analysis results of tool life prediction, cutting parameter optimization suggestions and performance comparison of various brands of tools by collecting tool usage data and analyzing its wear trend, and visualizing the analysis results; based on the historical usage data of the tool, the system analyzes the correlation between tool wear and processing time, cutting parameters, and workpiece materials, and establishes a tool life prediction model. Through machine learning algorithms, real-time monitoring data such as cutting force, vibration frequency, and temperature are pattern recognized to dynamically correct the remaining life prediction value. For different workpiece types and processing stages, the system automatically generates optimization suggestions for cutting speed, feed rate, and cutting depth, etc. parameters to extend the tool life while ensuring processing accuracy. At the same time, the system compares and analyzes the life distribution, wear curve, and failure rate of tools of the same type but different brands, and generates a brand performance evaluation matrix combined with cost factors. All analysis results are displayed through dynamic charts, including tool life decay curve, parameter optimization heat map, and brand comparison radar chart, etc. visual forms.

[0039] In an embodiment, the step S5: generating analysis results of tool life prediction, cutting parameter optimization suggestions and performance comparison of various brands of tools by collecting tool usage data and analyzing its wear trend, and visualizing the analysis results, specifically includes the following steps: Step S51: collecting real-time running data during tool usage, monitoring the change trend of tool geometric parameters, recording cumulative wear and historical wear trend data; specifically, collecting real-time running data during tool usage includes cutting force, vibration frequency, temperature change, processing time and workpiece surface quality parameters, which are obtained synchronously through in-machine tool setting gauge and built-in sensors of machine tool; monitoring the change trend of tool geometric parameters is achieved by periodic tool measurement, recording the change amount of edge wear width, relief wear band, tool tip radius and coating peeling area; cumulative wear is calculated by the central management system based on historical measurement data, and is associated with processing workpiece type, material hardness and cutting parameters; historical wear trend data is generated by fitting the wear rate curve of each measurement time point, and the difference between rough machining and finishing stage is distinguished; Step S52: Based on the historical wear trend data, combined with the current machining parameters and the cumulative wear amount, a dynamic life prediction model of the tool is established, the life prediction result of the tool is obtained, and a warning signal is triggered when the life prediction result approaches the safety threshold; Specifically, the central management system collects the wear data of the tool at different machining stages, and establishes the correlation between the wear amount and the machining time, and the cutting parameters. The system statistically analyzes the historical machining records of each tool, extracts the wear rate curve of the tool under different workpiece types and different cutting parameters. In the process of tool use, the type of the current machining workpiece, the cutting parameters (such as cutting speed, feed rate, cutting depth) and the actual machining time are monitored in real time, and the theoretical wear increment under the current machining condition is calculated combined with the historical wear rate curve of the tool. The system accumulates the wear increment of each machining, and compares it with the preset safety wear threshold, dynamically updates the residual life prediction value of the tool. When the cumulative wear amount approaches the safety threshold, the system automatically generates a warning signal to remind the operator to prepare for tool replacement. At the same time, the system will dynamically adjust the cutting parameters of the subsequent machining tasks according to the wear state and the residual life of the current tool, prolong the service life of the tool under the premise of ensuring the machining quality; Step S53: Obtain the correlation between tool wear rate and machining efficiency under different cutting parameter combinations, select the optimal balance point of wear rate and machining efficiency through data fitting and optimization algorithm, and generate optimization adjustment suggestions of cutting speed, feed rate and cutting depth; Specifically, according to the cutting parameter records (such as cutting speed, feed rate, cutting depth) in the tool historical data and the corresponding tool wear amount, machining time and other indicators, a multi-parameter correlation model is established. The function relationship between wear rate and cutting parameters is fitted by least squares method, and the response surface model of machining efficiency and cutting parameters is constructed. A multi-objective optimization algorithm (such as NSGA-II) is used to solve the Pareto front of wear rate minimization and machining efficiency maximization, and the non-dominated solution set is extracted based on the process constraint condition to select the optimal balance point. Finally, the recommended cutting parameter combination corresponding to each process is output, including spindle speed correction value, per tooth feed rate adjustment range and axial / radial cutting depth suggestion value; Step S54: Statistical analysis of the service life, wear trend curves and failure rate data of different brands of cutting tools under the same workpiece type, establish a multi-dimensional brand performance rating system, comprehensively evaluate the cost-effectiveness, and output the performance comparison results of each brand of cutting tools; specifically, statistical analysis of the service life data of different brands of cutting tools under the same workpiece type, including average life, life distribution range and standard deviation; analyze the wear trend curves of each brand of cutting tools under different processing parameters, and record the changes in characteristic parameters of key wear stages; collect the failure rate data of each brand of cutting tools in actual processing, distinguish the types of failures and statistically analyze the frequency of occurrence. Based on the above data, a multi-dimensional brand performance rating system is established, and evaluation indicators such as life weight, wear stability coefficient, and failure risk coefficient are set. A weighted algorithm is used to calculate the comprehensive performance score; combined with economic factors such as the purchase cost and maintenance cost of each brand of cutting tools, a cost-effectiveness evaluation model is constructed, and the most optimal selection recommendation is obtained through cost-performance ratio analysis. The final output includes an analysis report containing a brand performance comparison radar chart, a cost-effectiveness ranking table, and a selection recommendation description; Step S55: Visually display the tool life prediction results, optimization and adjustment suggestions, and performance comparison results of tools of various brands; specifically, use a dashboard to dynamically display the percentage of remaining tool life, and use a color gradient bar to visually indicate the degree of wear; use a line graph to display the historical wear trend curve, and superimpose the predicted life reference line for comparison. Cutting parameter optimization suggestions use a three-dimensional surface graph to present the relationship between wear rate and processing efficiency under different parameter combinations, and mark the optimal parameter range. Brand performance comparison uses a radar chart to display the score distribution of each brand in dimensions such as life, stability, and cost-effectiveness, supplemented by a bar chart to show the average service life comparison under the same working conditions. All visualization elements support interactive operations, allowing users to click to view detailed data or switch to different analysis perspectives.

[0040] Based on steps S51 to S55, by real-time monitoring of tool wear status and combining historical data analysis, the system can dynamically predict the remaining life and proactively push replacement suggestions. At the same time, it automatically generates cutting parameter optimization solutions based on multi-dimensional data cross-comparison, intuitively displays the performance difference curves of tools from different brands, and provides intelligent data support for process improvement and procurement decisions, significantly improving the scientific nature and foresight of tool management.
