Technical Field

[0001] This application relates to the field of CNC machine tool technology, and more specifically, to control methods, systems, electronic devices, and storage media for CNC machine tools. Background Technology

[0002] CNC machine tools typically operate independently, or achieve limited data interaction through simple point-to-point communication. Specifically, each CNC machine tool runs its own control software, independently completing operations such as uploading machining programs, activating workpieces, starting machining, and monitoring operation. The lack of a unified scheduling and coordination mechanism between different machine tools makes it difficult for multiple machine tools to form a cohesive machining system.

[0003] Therefore, there is an urgent need in the market for a control method that can centrally manage and uniformly schedule multiple CNC machine tools. Summary of the Invention

[0004] To address the aforementioned issues, this invention proposes a control method, system, electronic equipment, and storage medium for CNC machine tools, which enables intelligent allocation of machine tool processing tasks, thereby improving machine tool utilization and processing efficiency.

[0006] In one embodiment, the machine tool status information includes at least one of working status, machining progress, alarm information, and working parameters; the step of acquiring the machine tool status information of multiple CNC machine tools then includes: generating machine tool monitoring information based on the machine tool status information; and visually displaying the machine tool monitoring information.

[0007] In one embodiment, the production task information includes processing tasks, processing requirements, and scheduling strategies. The step of allocating CNC machine tools to execute the production task information based on the machine tool status information includes: confirming available machine tools based on the working status, the working parameters, the processing requirements, and / or the processing progress; determining a target machine tool from the available machine tools based on the scheduling strategy; and allocating the processing task to the target machine tool based on the scheduling strategy.

[0010] In one embodiment, the scheduling strategy includes at least one of delivery priority, cost priority, and balance priority; the step of determining a target machine tool from the available machine tools based on the scheduling strategy includes: when the scheduling strategy is delivery priority, setting all or a first number of the available machine tools as the target machine tool; when the scheduling strategy is cost priority, setting one machine tool from the available machine tools as the target machine tool; when the scheduling strategy is balance priority, setting a second number of the available machine tools as the target machine tool, wherein the first number is greater than the second number.

[0011] In one embodiment, the step of acquiring machine tool status information of multiple CNC machine tools includes: if the alarm information of the machine tool is a response timeout alarm or an execution failure alarm, then based on the machining progress of the machine tool, the unfinished machining tasks are evenly distributed to the target machine tool.

[0021] The foregoing and other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of preferred embodiments with reference to the accompanying drawings. Through the description of the specific embodiments, a more in-depth and specific understanding can be gained of the technical means and effects adopted by the present invention to achieve its intended purpose. However, the accompanying drawings are for reference and illustration only and are not intended to limit the present invention.

[0022] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0023] Figure 1 This is a flowchart of the control method for a CNC machine tool according to the first embodiment of the present invention.

[0024] like Figure 1 As shown, the control method for CNC machine tools, applied to a central control platform, includes the following steps: Step S11: Obtain the machine tool status information of multiple CNC machine tools.

[0025] Specifically, it establishes connections with multiple machine tool control units, periodically sends query commands to these control units, and obtains machine tool status information for multiple CNC machine tools based on feedback information returned by these control units. The machine tool status information includes at least one of the following: working status, machining progress, alarm information, and working parameters. The working status indicates whether the machine tool is currently in machining mode; the machining progress indicates the completion percentage of the currently executed machining task and / or the remaining machining time; the alarm information indicates whether there are any abnormal alarms and the type of alarm; and the working parameters indicate at least one of the following: spindle speed, feed rate, tool status, power load, machining accuracy, maximum workpiece size, and minimum workpiece size.

[0026] Specifically, after step S11, the process includes generating machine tool monitoring information based on the machine tool status information and visually displaying the machine tool monitoring information. This allows managers to intuitively and in real-time grasp the operating status of multiple CNC machine tools, reducing the workload of manual inspections and information summarization, and improving the real-time performance, accuracy, and overall production management efficiency of equipment status monitoring.

[0027] In one embodiment, the machine tool status information of each machine tool is stored to form a unified production data acquisition and management platform, which provides data support for subsequent production statistical analysis, equipment operation evaluation, process optimization and predictive maintenance, thereby improving the overall intelligence level of the production system.

[0028] Step S12: Obtain production task information.

[0029] Specifically, the system acquires production task information from users via local input or input from a host computer. The production task information includes processing tasks, processing requirements, and scheduling strategies. Processing tasks are used to characterize the number of workpieces to be processed and the processing procedure. Processing requirements are used to characterize processing constraints such as required processing accuracy, required surface roughness, required tolerance range, required material type, and maximum allowable processing time. Scheduling strategies are used to characterize the allocation strategy for production tasks, including at least one of delivery priority, cost priority, and balance priority.

[0030] Step S13: Based on the machine tool status information, assign the CNC machine tool to execute the production task information.

[0031] Specifically, such as Figure 2 As shown, step S13 includes: Step S131: Based on the working status, the working parameters, the processing requirements and / or the processing progress, confirm the available machine tool.

[0032] Specifically, when the working state and / or processing progress of the machine tool meet the first or second condition, and the working parameters of the machine tool meet the processing requirements, the machine tool is set as an available machine tool.

[0033] Specifically, when the working state is idle, the working state is determined to meet the first condition; when the working state is processing and the remaining processing time is less than the preset time, the working state and processing progress are determined to meet the second condition.

[0034] Step S132: Based on the scheduling strategy, determine the target machine tool from the available machine tools.

[0035] Specifically, when the scheduling strategy is delivery priority, all or a first number (e.g., 10) of the available machine tools are set as target machine tools; when the scheduling strategy is cost priority, the processing cost of each available machine tool is obtained, and the available machine tool with the lowest processing cost is set as the target machine tool to reduce the overall production cost; when the scheduling strategy is balance priority, a second number (e.g., 5) of the available machine tools are set as target machine tools; wherein the first number is greater than the second number.

[0036] Step S133: Assign the machining task to the target machine tool based on the scheduling strategy.

[0037] Specifically, when there are multiple target machine tools, the machining tasks are evenly distributed among each target machine tool; when there is only one target machine tool, the machining tasks are distributed among all target machine tools.

[0038] In one embodiment, after step S11, if the alarm information of the machine tool is a response timeout alarm or an execution failure alarm, then based on the machining progress of the machine tool, the unfinished machining tasks are evenly distributed to the target machine tool.

[0039] The control method for CNC machine tools provided by this invention acquires machine tool status information and production task information from multiple CNC machine tools, and allocates production tasks to be executed by the CNC machine tools based on the machine tool status information.

[0044] In one embodiment, the central control platform 32 stores the machine tool status information locally.

[0045] The machine tool control unit 33 is connected to a machine tool 34. The machine tool control unit 33 is used to acquire the machine tool status information of the CNC machine tool and send the machine tool status information of the CNC machine tool to the central control platform 32; receive the production task information assigned by the central control platform 32, and send the corresponding control commands to the machine tool 34 based on the assigned production task information.

[0046] The machine tool 34 is used to send its own machine tool status information to the machine tool control unit 33 and to receive and execute the control commands sent by the machine tool control unit 33.

[0047] In one embodiment, when the machine tool control unit 33 fails to communicate with the machine tool 34, it executes a reconnection procedure; if the reconnection procedure fails, it sends a response timeout alarm message to the central control platform 32.
