[0041]

[0042] Among them, K represents the wear rate of the current tool, L1 represents the current tool diameter, L0 represents the initial tool diameter, when K<0.1, it means that the current tool wear is in a normal state, when 0.1≤K<0.2, it means that the current tool has a wear problem and a tool replacement plan needs to be arranged, and when K≥0.2, it means that the current tool has been severely worn and needs to be shut down for maintenance.

The instruction generation unit will generate corresponding control instructions according to the analysis results of the parameter identification module, and the instruction transmission unit will transmit the generated control instructions to the corresponding equipment in the CNC machine tool.

[0044] In one embodiment of the present invention: the fault analysis and optimization module includes a fault prediction unit and an optimization plan formulation unit. The fault analysis unit collects historical operating data of various parameters of CNC machine tool equipment, as well as past fault records and maintenance information from the cloud database, and associates different types of faults with corresponding parameter changes to establish a fault feature database.

The evaluation content includes the possibility, severity, and impact of the fault on equipment performance and production. According to the type of fault and the evaluation result, a corresponding optimization plan is formulated and the plan is transmitted to the control module.

A cost calculation unit is inserted into the optimization plan formulation unit, and the cost calculation unit calculates the price cost and time cost of the optimization plan.

[0046] In one embodiment of the present invention: the user interface module includes a data display unit and an interaction unit. The data display unit will display the data of the CNC machine tool equipment parameters to the user in the form of a chart. The interaction unit is used for the user to query the historical data of the equipment, set parameters and view fault analysis results through the interface. At the same time, the system can also send notifications and alarm information to the user through the interface.

At the same time, the order of the chart data is arranged according to the number of clicks of the user. For abnormal data, the data display unit will mark and move the data to the first row for display.

[0047] Example 1, please refer to the attached Figure 1 In a large-scale machining workshop, a parameter identification system for CNC machine tools based on cloud computing was installed. First, the data acquisition module began to play a key role. The sensor unit accurately collected various operating parameters such as temperature, pressure, and speed on the CNC machine tools. These sensors are distributed in key parts of the equipment and can monitor the operating status of the equipment in real time. The marking unit adds a clear mark to each set of collected data to ensure that the data can accurately correspond to the specific CNC machine tools, providing clear source information for subsequent analysis and processing. The data transmission unit uses a stable wireless transmission method to quickly transmit the collected data to the data processing module, avoiding the problems of complex wiring and difficult maintenance that may be caused by traditional wired transmission. After the data processing module cleans and normalizes the data, the model training unit in the cloud computing module regularly extracts data from the processed data area and uses powerful machine learning algorithms, such as neural networks or random forest algorithms, to establish a model that can accurately identify the key parameters of the equipment. With the continuous accumulation of data and the continuous optimization of the model, the accuracy and generalization ability of the model are gradually improved;

[0048] When new data is collected, the parameter identification module takes action quickly. The model application unit applies the trained model to the new data to accurately identify key parameters such as tool wear rate. The state analysis unit uses a specific formula to make judgments based on the tool wear rate. If a tool replacement plan is required, the control module responds immediately. The instruction generation unit quickly generates corresponding adjustment instructions, such as reducing the cutting speed or adjusting the feed rate, to reduce the degree of tool wear. The instruction transmission unit accurately transmits the instructions to the corresponding CNC machine tool equipment to achieve real-time control of the equipment. At the same time, the fault analysis and optimization module continuously collects and analyzes data, predicts faults in advance, and formulates optimization plans.

[0049] The user interface module provides users with intuitive equipment parameter display and convenient interactive functions. In addition, the data display unit can intelligently adjust the content and form of data display according to the user's browsing history and focus. For example, if the user often pays attention to tool wear rate and temperature parameters, the system will place the data of these parameters in a more prominent position. The arrangement order of chart data is dynamically adjusted according to the number of clicks of the user, and the data that the user pays most attention to or views most frequently is placed in the front row, so that users can quickly obtain key information. For abnormal data, the system will not only automatically mark it, but also move this data to the first row for display, ensuring that users can notice potential problems at the first time, improving the efficiency of equipment monitoring and troubleshooting.

[0050] Example 2, please refer to the attached Figure 1 An automobile parts manufacturer introduced the parameter identification system of the present invention. The data acquisition module collects the operating parameters of multiple CNC machine tools in real time to ensure the accuracy of the data. The cloud computing module efficiently stores data and establishes an accurate parameter identification model. When the parameter identification module finds that the tool wear rate of a certain device is close to the threshold that requires a tool replacement plan, the system immediately issues an alarm, and the control module responds quickly to generate instructions to adjust the equipment operating parameters to reduce the tool wear rate. The fault analysis and optimization module predicts the possible fault type and time by analyzing historical data and real-time monitoring, formulates optimization plans and considers cost calculations, and the user interface module displays the equipment parameter data in the form of charts, which is convenient for users to query historical data and view fault analysis results, thereby improving the efficiency and accuracy of equipment management.

[0051] Example 3, please refer to the attached Figure 1 In the aerospace parts manufacturing plant, a parameter identification system for CNC machine tools based on cloud computing is used. The data acquisition module comprehensively collects the operating parameters of various CNC machine tools and equipment, which are stored in the cloud database after being processed by the data processing module. The parameter identification module accurately identifies key equipment parameters, such as tool wear rate. When the tool wear rate shows that the equipment is in a state where it needs to be shut down for maintenance, the control module immediately stops the equipment to avoid further damage. The fault analysis and optimization module quickly formulates optimization plans based on the optimization plan database established based on historical fault records and manufacturer fault test records, and evaluates the plan cost through the cost calculation unit. The user interface module intelligently adjusts the data display content and form to facilitate users to quickly obtain key information, conduct troubleshooting and equipment maintenance in a timely manner, and ensure production efficiency and stability.

[0052] Specifically, the operating parameters of CNC machine tools are collected in real time through the data acquisition module, and are cleaned and normalized by the data processing module to ensure the accuracy and consistency of the data. The cloud computing module uses machine learning algorithms to establish an equipment parameter identification model, which can accurately identify the key parameters of the equipment and analyze the operating status of the equipment in real time through the parameter identification module. This helps to promptly discover potential wear or failure problems of the equipment, so that measures can be taken in advance to avoid equipment downtime due to excessive wear or sudden failure, thereby improving the operating efficiency and processing accuracy of the equipment.

[0053] Specifically, the fault analysis and optimization module collects historical operating data and fault records, establishes a fault feature database, and uses an anomaly detection algorithm to monitor the operating status of the equipment in real time. Once an abnormal situation is detected, it can quickly predict the time and type of the fault, and formulate an optimization plan based on the prediction results. The optimization plan formulation unit not only considers the type and severity of the fault, but also evaluates the price and time costs of different optimization plans through the cost calculation unit, so as to select the optimal plan. This helps enterprises prevent faults, reduce downtime, reduce maintenance costs, and improve overall production efficiency and economic benefits.

[0054] Specifically, by introducing the intelligent data priority display function in the user interface module, the system can intelligently adjust the content and form of data display according to the user's browsing history and focus. In particular, the arrangement order of chart data is dynamically adjusted according to the number of clicks of the user, and the data that the user pays most attention to or views most frequently is placed in a prominent position. For abnormal data, the system will not only automatically mark it, but also move the data to the first row for display, ensuring that users can notice potential problems at the first time. This intelligent data priority display mechanism improves the level of personalization of the user experience, allowing users to obtain key information faster, thereby more effectively monitoring and troubleshooting equipment.
