[0055] The assembly data entry module 110 is the first data contact point in the production process of the numerically controlled machine tool. During the assembly stage of the numerically controlled machine tool, this module is responsible for capturing and recording all key data during the assembly process in real time, such as the installation sequence of components, assembly accuracy, tightening torque, etc. After these data are entered and stored, they will be immediately uploaded to the digital mainline database 150, providing a solid foundation for subsequent data analysis and traceability.

[0058] The regular physical examination data entry module 140 is responsible for data collection during the service period of the numerically controlled machine tool. During the use of the machine tool, the system will conduct a comprehensive inspection of it regularly and record all data during the inspection process, such as the wear condition of the machine tool, the trend of performance decline, the life prediction of key components, etc. These data are of great significance for evaluating the health status of the machine tool, formulating maintenance plans, and predicting potential faults.

[0059] The digital mainline database 150 is the core of the entire system. It is responsible for collecting, storing, and managing data from each entry module, forming a comprehensive and coherent data system for the entire life cycle of the numerically controlled machine tool. Through this database, enterprises can conveniently query and analyze the data of each stage of the machine tool, explore the value behind the data, and provide strong support for the optimization and upgrading of the machine tool, fault warning, and intelligent decision-making.

As the core storage and management platform, the digital main line database 150 collects the full life cycle data of the numerical control machine tool from assembly, commissioning, compensation to regular physical examination. These data are interrelated and mutually verified, forming complete full life cycle through data of the numerical control machine tool, providing a solid foundation for subsequent data analysis and utilization. Through the unified data flow and full life cycle through data, the data at each stage is no longer isolated, but forms an effective value stream. Based on these data, in-depth data analysis can be carried out, the value behind the data can be mined, and the production process can be optimized, the efficiency can be improved, and the cost can be reduced. Aggregating and utilizing the full life cycle through data can provide more comprehensive and accurate data support for the enterprise. Based on these data, the enterprise can make more scientific and reasonable intelligent decisions, such as predictive maintenance, fault warning, production scheduling, etc., thereby enhancing the competitiveness of the enterprise and the market response speed.

By optimizing the input interface, providing a data verification mechanism and other means, data entry errors or omissions can be effectively avoided.

[0066] The assembly data storage unit 112 is responsible for systematically and structurally storing and managing all the assembly data input through the assembly data input unit 111 in each assembly process.

[0072] In the above embodiments, the debugging data acquisition and input unit 121 undertakes the important task of collecting debugging data from the internal and external environments of the numerical control system. During the debugging process of the CNC machine tool, this unit can extract key data such as the operating parameters, machining accuracy, and error compensation values of the machine tool from the numerical control system in real time. These data directly reflect the debugging status and performance of the machine tool. At the same time, this unit also has the ability to collect debugging data outside the numerical control system, such as obtaining physical quantity data such as vibration and temperature of the machine tool through an external sensor network, as well as observation records and adjustment operations during the debugging process manually entered. Through multi-channel and multi-dimensional data collection, the comprehensiveness and accuracy of the debugging data are ensured.

[0073] The debugging data storage unit 122 is responsible for systematically and structurally storing and managing all the debugging data collected and input through the debugging data acquisition and input unit 121 in each debugging link. This unit uses efficient data storage technologies and formats to organize the debugging data into debugging record files. These files not only contain various key data during the debugging process, but may also include auxiliary information such as timestamps, operator information, and debugging steps, so as to facilitate subsequent data traceability and analysis. The design of the storage unit fully considers the security and accessibility of the data, supports rapid retrieval and query of the data, and meets the data requirements in different scenarios.

[0074] As a bridge connecting the debugging data entry module 120 and the digital mainline database 150, the debugging data upload unit 123 undertakes the important task of accurately uploading the debugging record files stored in the debugging data storage unit 122 to the digital mainline database 150. During the upload process, this unit strictly follows the predetermined format and protocol to ensure the integrity and consistency of the data, and avoid data loss or damage during the transmission process. At the same time, the upload unit also supports the incremental upload and resume upload functions of the data to improve the efficiency and reliability of data upload. Through the debugging data upload unit 123, the debugging data can be integrated with other data in the whole life cycle of the CNC machine tool, providing strong support for subsequent data analysis, performance evaluation, and intelligent decision-making.

[0078] A compensation data upload unit 133 for uploading the compensation record file stored in the compensation data storage unit 132 to the digital mainline database 150.

[0079] In the above embodiment, the compensation data acquisition and input unit 131 is responsible for comprehensively capturing and recording compensation data during the accuracy compensation process before the CNC machine tool leaves the factory. This unit not only has the ability to directly extract compensation data from the CNC system, such as key information like compensation values, compensation point positions, and compensation effect verification, which directly reflect the detailed situation and effect of the machine tool accuracy compensation. At the same time, this unit also has the function of collecting compensation data outside the CNC system, such as obtaining the actual machining accuracy data of each component of the machine tool through high-precision measuring equipment, or special operation records and adjustment strategies manually entered during the compensation process. Through multi-channel and multi-dimensional data acquisition methods, this unit ensures the comprehensiveness and accuracy of the compensation data, providing a solid foundation for subsequent data analysis and processing.

[0080] The compensation data storage unit 132 undertakes the task of systematically and structurally storing and managing all the compensation data collected and input through the compensation data acquisition and input unit 131 in each compensation link. This unit uses data storage technologies and formats to organize the compensation data into compensation record files, which not only contain various key data during the compensation process, but also can include auxiliary information such as timestamps, operator information, and comparison of the machine tool status before and after compensation, for subsequent data traceability and analysis. The design of the storage unit fully considers the security and accessibility of the data, and adopts mechanisms such as encrypted storage and backup recovery to ensure that the compensation data will not be lost or damaged, and at the same time supports rapid retrieval and query of the data to meet the data requirements in different scenarios.

During the upload process, this unit strictly follows the predetermined format and protocol to verify and convert the compensation data to ensure the integrity and consistency of the data. At the same time, the upload unit also supports the functions of incremental upload and resume from breakpoint for data upload to improve the efficiency and reliability of data upload. Through the compensation data upload unit 133, the compensation data can be integrated with other data in the entire life cycle of the CNC machine tool, providing strong support for subsequent data analysis, performance evaluation, fault warning, and intelligent decision-making, which not only helps the enterprise better understand the accuracy compensation situation of the machine tool, but also provides a data basis for the optimization, upgrade, and continuous improvement of the machine tool.

[0082] In some embodiments of the present invention, the regular physical examination data entry module 140 includes a regular physical examination data collection and input unit 141, a regular physical examination data storage unit 142, and a regular physical examination data upload unit 143;

[0083] The regular physical examination data collection and input unit 141 is used to collect the regular physical examination data during the service period of the CNC machine tool from the CNC system after the CNC machine tool leaves the factory, and to collect and input the regular physical examination data outside the CNC system;

[0084] The regular physical examination data storage unit 142 is used to store all the regular physical examination data collected and input through the regular physical examination data collection and input unit 141 in each regular physical examination link as a health examination record file;

[0085] The regular physical examination data upload unit 143 is used to upload the health examination record file stored in the regular physical examination data storage unit 142 to the digital thread database 150.

[0086] In the above embodiments, the regular physical examination data collection and input unit 141 is responsible for constructing a collection network for multi-source heterogeneous health data, covering the entire life cycle of the CNC machine tool (from factory delivery to retirement and scrapping), and realizing the organic integration of the data embedded in the CNC system and the external detection data. Through deep integration with the CNC system via industrial communication protocols (such as MTConnect / OPC UA), it can capture real-time operation performance data such as spindle power fluctuations, feed axis acceleration, and servo motor current harmonics, and at the same time complete outlier filtering and feature extraction in combination with edge computing technology; for wear state data such as tool wear index and lead screw pair backlash, vibration spectrum analysis and laser interferometer on-line measurement technology are used to achieve accurate collection; in addition, through embedded sensors and infrared thermal imaging devices, environmental adaptation data such as the thermal deformation of the machine tool body and the PH value of the coolant can be obtained synchronously. For data that cannot be directly obtained by the CNC system (such as the off-line measurement results of third-party vibration sensors and the details of maintenance work orders), a standardized manual input interface and file import function are provided, supporting batch import in CSV / Excel format to ensure data integrity.

[0087] The regular physical examination data storage unit 142 adopts a hybrid storage architecture to achieve efficient management of massive health data. Unstructured binary data such as vibration spectrograms and infrared thermal images are stored through a distributed file system (such as Ceph), while structured data such as temperature and rotational speed are written in real time using a time series database (such as InfluxDB), supporting a write performance of millions of data points per second. Automatically aggregate data by day / week / month cycles to generate standardized health records (in JSON / XML format) containing metadata such as device ID, collection time, and health level, and achieve millisecond-level retrieval through a three-level index table (device ID - time range - health status). Adopt AES-256 encryption technology and triple backup mechanism to ensure that the data storage security reaches military-level standards, and at the same time support the data version backtracking function, which can restore the last 3 historical versions to meet the requirements of auditing and fault tracing.

[0088] The regular physical examination data upload unit 143 is responsible for securely and efficiently transmitting the health record files to the digital mainline database 150. Achieve seamless docking with the industrial 4.0 platform through RESTful API and JSON-LD data format, adopt an incremental upload strategy to only transmit newly added or modified files, and combine breakpoint resume and automatic retry mechanisms to ensure transmission reliability. Perform MD5 hash verification and Gzip compression (compression ratio up to 70%) before transmission, build a secure channel through TLS1.3 encryption and two-way certificate authentication, and receive a digital signature receipt confirmation after transmission. In the face of network fluctuations, automatically switch to the MQTT message queue asynchronous transmission mode, and write the upload failure records into the error log to trigger operation and maintenance alarms.

[0089] The regular physical examination data entry module 140 builds the data foundation for the health management of CNC machine tools through standardized data collection, structured storage, and intelligent upload. The high-quality data output can directly support the training of predictive maintenance models, remaining life prediction, and the construction of health scoring systems, and at the same time form an enterprise-level health big data lake to provide data support for extended applications such as process parameter optimization and energy efficiency management.

[0100] In some embodiments of the present invention, the debugging data includes current loop sample file data, speed loop sample file data, and position loop sample file data;

[0101] The current loop sample file data includes file basic information, machine tool axis number, starting position, feed speed, original current load data, conversion coefficient, and sample index results;

[0102] The speed loop sample file data includes file basic information, machine tool axis number, starting position, feed speed, original speed data, conversion coefficient, and sample index results;

[0103] The position loop sample data includes file basic information, machine tool axis number, starting position, feed speed, original time position data, conversion coefficient, and sample index results.

[0104] In the above embodiments, the current loop sample file data records various parameters of the machine tool during the current loop debugging process. Specifically, the current loop sample file data includes basic file information (such as file name, creation time, recording personnel, etc., used to identify and trace the sample file), machine tool axis number (clarifying the machine tool axis corresponding to the data for subsequent analysis), starting position (recording the position of the machine tool axis at the start of debugging, providing a basis for data analysis), feed speed (the moving speed of the machine tool axis during the debugging process, affecting the change of current load), original current load data (the current load value directly collected from the current loop, which is the basis for evaluating the performance of the current loop), conversion coefficient (used to convert the original data into a form that is easier to analyze, such as converting the current value into a percentage or a normalized value), and sample index results (key indicators obtained through processing and analysis of the original data, such as current fluctuation range, average value, etc., used to evaluate the stability and performance of the current loop).

[0105] The speed loop sample file data focuses on the performance of the machine tool during the speed loop debugging process. Similar to the current loop sample file data, the speed loop sample file data also includes basic information such as basic file information, machine tool axis number, starting position, and feed speed. The difference is that the key data in the speed loop sample file data are the original speed data (the speed value directly collected from the speed loop, reflecting the actual moving speed of the machine tool axis) and the corresponding conversion coefficient and sample index results (such as speed stability, acceleration, etc., used to evaluate the control accuracy and dynamic performance of the speed loop).

[0106] The position loop sample data records the position information of the machine tool during the position loop debugging process. As the most critical part of the numerical control machine tool control system, the performance of the position loop directly affects the machining accuracy and positioning accuracy of the machine tool. The position loop sample data also includes basic information such as basic file information, machine tool axis number, starting position, and feed speed, as well as time-position original data (recording the position information of the machine tool axis at different time points, which is an important basis for analyzing the performance of the position loop), conversion coefficient, and sample index results (such as position deviation, repeat positioning accuracy, etc., used to evaluate the static and dynamic performance of the position loop).

[0107] These debugging data, by comprehensively and meticulously recording various performance parameters of the machine tool during the debugging process, provide strong data support for the performance evaluation, fault troubleshooting, and optimization and upgrading of the numerical control machine tool. At the same time, these data also provide a solid foundation for advanced applications such as intelligent management, remote monitoring, and predictive maintenance of the machine tool.

[0108] In some embodiments of the present invention, the compensation data includes thermal error compensation file data, geometric error compensation file data, and contour error compensation file data;

[0109] The thermal error compensation file data includes the measured temperature data of the spindle temperature sensor, the actual compensation data of the spindle error compensation, and the spindle error compensation coefficient;

[0110] The geometric error compensation file data includes the actual coordinate data of the axis, the horizontal straightness measurement data, the vertical straightness measurement data, the yaw angle measurement data, the roll angle measurement data, the positioning error, and the pitch angle measurement;

[0111] The contour error compensation file data includes current, command position, actual position, actual error, compensation error, and line number.

[0112] In the above embodiments, the thermal error compensation file data is the key data for compensating the errors generated by the machine tool due to temperature changes. It specifically includes the measured temperature data of the spindle temperature sensor, which reflects the temperature changes of the spindle during operation in real time and is the basis for thermal error compensation. At the same time, the file also records the actual compensation data of the spindle error compensation, that is, the specific compensation values for the spindle error according to the temperature changes. These compensation values can effectively reduce the machining errors caused by thermal deformation. In addition, the spindle error compensation coefficient is also an important part of the thermal error compensation file data. It is used to convert the temperature data into specific compensation values and is the key to achieving precise thermal error compensation.

[0113] The geometric error compensation file data mainly focuses on the errors in the geometric shape and position of the machine tool. It details the actual coordinate data of the axis, which reflects the position information of each axis of the machine tool during actual operation. At the same time, the file also includes the horizontal straightness measurement data, the vertical straightness measurement data, the yaw angle measurement data, the roll angle measurement data, and the pitch angle measurement data, etc. These data comprehensively describe the error situation of the machine tool in terms of geometric shape and position. In addition, the positioning error is also an important part of the geometric error compensation file data, which reflects the accuracy of the machine tool during the positioning process. By analyzing and processing these data, precise compensation for the geometric errors of the machine tool can be achieved, improving the machining accuracy of the machine tool.

[0114] The contour error compensation file data mainly focuses on the contour shape errors during the machining process of the machine tool. It details key information such as current, command position, actual position, actual error, compensation error, and line number. The current data reflects the power state of the machine tool during machining, while the command position and actual position represent the positions that the machine tool should reach and actually reach, respectively. The actual error is the difference between the command position and the actual position, and the compensation error is the compensation value for reducing the actual error. The line number is used to identify different machining strokes or machining segments, facilitating the segmented analysis and compensation of contour errors. By comprehensively processing these data, precise compensation for the contour errors of the machine tool can be achieved, improving the quality and accuracy of the machined parts.

[0115] These compensation data together constitute a complete record of the compensation process of the CNC machine tool, providing strong support for subsequent data analysis, error tracing, and optimization of compensation strategies. By comprehensively collecting and effectively managing these compensation data, enterprises can more accurately grasp the error situation of the machine tool, improve the machining accuracy and stability of the machine tool, and thus enhance their market competitiveness.

[0116] In some embodiments of the present invention, the regular physical examination data includes regular physical examination sample result file data;

[0117] The regular physical examination sample result file data includes file header information, file generation time, index number, index name, measured index value, standard index range, and index unit.

[0118] In the above embodiments, the regular physical examination data details the regular detection results of various key performance indicators of the machine tool during its service life, providing valuable data support for the health status assessment of the machine tool, the formulation of maintenance plans, and the early warning of potential faults. The regular physical examination data mainly includes regular physical examination sample result file data, which are stored in a structured manner for easy subsequent analysis and processing.

[0119] File header information: This is the identification part of the file, usually including the file name, file version, the number or name of the machine tool recorded, etc., which is used to quickly identify and trace the source and basic information of this physical examination sample result file.

[0120] File generation time: Records the specific time when this file was created or last updated, which is of great significance for tracking the physical examination history and analyzing the change trend of the machine tool performance over time.

[0121] Index number: Each detection index has a unique number, which is convenient for quickly locating and referring to specific indexes in a large amount of data.

[0122] Index name: Specifically describes the content of the detection. These index names directly reflect the key performance parameters of the machine tool during operation. For example, the positive load current and negative load current reflect the current consumption of the machine tool in different working directions; the positive current mean square deviation and negative current mean square deviation are used to evaluate the stability of the current; the positive current load ratio and negative current load ratio reveal the relationship between the current and the load; the tracking error measures the tracking accuracy of the machine tool control system for the command signal; and the speed fluctuation reflects the speed stability of the machine tool during operation.

[0123] Measured index value: This is the value actually measured during the physical examination process, which directly reflects the performance of the machine tool in the current state.

[0124] Indicator standard range: It stipulates the numerical range that each indicator should be in under normal operation conditions, and is an important basis for evaluating whether the machine tool performance meets the standards.

[0125] Indicator unit: It clarifies the measurement units of the measured values of each indicator, such as amperes (A), millimeters (mm), seconds (s), etc., to ensure the accuracy and comparability of data.

[0126] Through long-term accumulation and analysis of the data in the regular physical examination sample result files, the changing trends of the machine tool performance can be revealed, potential faults can be predicted, and scientific basis can be provided for the preventive maintenance and optimization and upgrading of the machine tool.

[0127] In some embodiments of the present invention, the digital thread database 150 includes: a data reception layer 151, a data storage layer 152, and a data access layer 153;

[0128] Among them, the data reception layer 151 receives the data uploaded by the assembly data entry module 110, the debugging data entry module 120, the compensation data entry module 130, and the regular physical examination data entry module 140;

[0129] The data storage layer 152 includes storing the assembly, debugging, compensation, and regular physical examination data by using the vertical association storage mechanism and the horizontal association storage mechanism;

[0130] The data access layer 153 provides a network interface for accessing the data stored in the data storage layer 152, and accesses, browses, and downloads the assembly data, debugging data, compensation data, and regular physical examination data through a preset protocol.

[0131] In the above embodiments, the data reception layer 151, as the front-end interface of the database, is responsible for receiving the massive data uploaded by the assembly, debugging, compensation, and regular physical examination data upload modules. This layer has high flexibility and compatibility, can process data in different formats and from different sources, and uses the efficient storage mechanism of the data storage layer 152 to quickly and accurately store this data. The data reception layer 151 also undertakes the tasks of data verification and cleaning to ensure that only the data meeting the quality requirements can enter the data storage layer 152, thus guaranteeing the data quality of the entire database.

[0132] The data storage layer 152 is the core part of the database, and it is responsible for comprehensively and systematically storing the assembly, debugging, compensation, and regular physical examination data. This layer not only provides the basic storage function, but also introduces the vertical association storage mechanism and the horizontal association storage mechanism to realize the in-depth mining and efficient utilization of data.

[0133] Longitudinal Correlation Storage Mechanism: This mechanism takes the machine tool number as the dimension and closely correlates the assembly, commissioning, compensation, and regular inspection data of a single CNC machine tool, forming a complete longitudinal historical data record chain. Through this record chain, users can clearly track the full life cycle data of a single machine tool from assembly to scrapping, providing strong data support for the performance analysis, fault troubleshooting, and optimization and upgrading of the machine tool.

[0134] Transverse Correlation Storage Mechanism: This mechanism takes the machine tool model as the dimension and stores the assembly, commissioning, compensation, and regular inspection data of multiple CNC machine tools of the same model in a transverse comparison manner. Through this storage method, users can conveniently compare the performance of different machine tools at the same stage or on the same indicator, thereby discovering potential problems or optimization points and providing data basis for the batch improvement and standardized production of machine tools.

[0135] The data access layer 153, as the backend interface of the database, provides users with a convenient way to access the data stored in the data storage layer 152. This layer supports users to access, browse, and download assembly data, commissioning data, compensation data, and regular inspection data in various ways through preset protocols (such as HTTP and HTTPS protocols).

[0136] For assembly data, users can quickly locate the required data records through retrieval conditions such as the equipment number and equipment model at the time of data entry and view the detailed assembly information.

[0137] For commissioning data, in addition to using the equipment number and equipment model as retrieval conditions, users can also filter according to the generation time of the commissioning data to more accurately obtain the commissioning data for a specific time period.

[0138] The access, browsing, and downloading methods of compensation data and regular inspection data are similar. Users can flexibly retrieve according to conditions such as the generation time of the data, equipment number, and equipment model to meet different data requirements.

[0139] Through the close cooperation of these three layers, the digital thread database 150 realizes the comprehensive management, efficient storage, and convenient access of the full working cycle data of CNC machine tools, providing a solid data foundation for the production management, quality control, and intelligent decision-making of enterprises.

This breaks the data fragmentation produced by different software, realizes centralized data management and efficient data transmission, and significantly improves the efficiency of information transmission. As the core storage and management platform, the digital mainline database 150 collects data from the entire life cycle of the CNC machine tool, from assembly, debugging, compensation, to regular checkups. This data is interconnected and mutually verified, forming a complete set of data that runs through the entire life cycle of the CNC machine tool, providing a solid foundation for subsequent data analysis and utilization. Through a unified data flow and full-lifecycle data, data from each stage is no longer isolated, but forms an effective value stream. Based on this data, in-depth data analysis can be carried out to explore the value behind the data, thereby optimizing production processes, improving efficiency, and reducing costs. Aggregating and utilizing data throughout the entire life cycle can provide enterprises with more comprehensive and accurate data support. Based on this data, enterprises can make more scientific and reasonable intelligent decisions, such as predictive maintenance, fault warning, production scheduling, etc., thereby improving the competitiveness of the enterprise and the speed of market response.
