[0039] Specifically, the notch position can be accurately measured by an image sensor to ensure the accuracy of the notch path.

[0040] S200, determining two corresponding processing paths based on the notch path, and determining processing parameters corresponding to the two processing paths; wherein the processing parameters include a cutting speed, a cutting force and a theoretical processing time of a cutting machine;

[0041] S300, controlling the cutting machine to perform synchronous processing according to the processing parameters, and detecting the actual processing time of the processing path at intervals during the processing, and adjusting the cutting speed based on the actual processing time and the corresponding theoretical processing time;

[0042] S400, detecting the remaining processing time of the two processing paths in real time, and when the remaining processing time of any processing path is lower than the time threshold, dynamically adjusting the processing parameters of the two processing paths based on the remaining processing time of the two processing paths until the processing of the two processing paths is completed.

[0043] In the embodiment provided by the present invention, the machining process is monitored in real time, the machining parameters are adjusted dynamically, the errors are corrected in time, and the synchronous operation of the cutting machine is precisely controlled to ensure the machining accuracy and efficiency of the two machining paths, thereby achieving synchronous and precise machining of the notches of the profiled materials. Through real-time monitoring and adjustment, the error accumulation in the machining process is effectively reduced, ensuring that the two paths are synchronously processed, and improving production efficiency and product quality.

[0044] As an improvement of the above embodiment, in S200, determining two corresponding processing paths based on the notch path and determining processing parameters corresponding to the two processing paths include:

[0045] S210, obtaining material parameters of the profiled material and the shape of the notch edge line to determine a processing parameter range; the processing parameter range includes a cutting speed range and a cutting force range;

[0046] S220, within the cutting speed range corresponding to each cutting segment, with the goal of minimizing the cutting speed change rate between two adjacent cutting segments, obtain the cutting speed corresponding to each cutting segment, determine the cutting force corresponding to the cutting speed, and determine the theoretical processing time based on the path length of each cutting segment and the corresponding cutting speed.

[0047] In this embodiment, the strength and plasticity of the material are taken into consideration when determining the cutting force to prevent the material from breaking or deforming too much. The cutting force is matched with the material properties through precise calculation to ensure the stability and accuracy of the notch processing of the profiled material.

[0048] As an improvement of the above embodiment, in S210, obtaining the material strength of the profile and the shape of the notch edge line to determine the range of processing parameters includes:

[0049] S211, determining the minimum cutting force required for processing the special-shaped material according to the hardness and thickness of the special-shaped material; obtaining the maximum cutting force of the pipe cutting machine, and determining the cutting force range according to the minimum cutting force and the maximum cutting force;

[0051] S213, dividing the cutting trajectory into a plurality of cutting segments of equal length, and determining a corresponding cutting speed range according to the curvature of the cutting segment.

[0052] Each cutting section is configured with a corresponding cutting speed and theoretical processing time to ensure the continuity and stability of the cutting process. By accurately calculating the cutting parameters of each section, the cutting machine can be more efficient and accurate when performing processing tasks, while reducing unnecessary material waste and improving the overall performance of profile notch processing.

[0056] By implementing the improved example of the present invention, the calculated radius of curvature is compared with the safety parameter threshold to ensure that the material will not break or deform within the cutting speed range. The tensile strength and toughness of the material are specifically considered to select the best cutting speed range. By simulating the cutting process, the matching of the cutting speed and the material resistance is optimized to achieve the best effect in the processing process, ensuring that the final product meets the design specification requirements.

[0057] As an improvement of the above embodiment, in S300, the cutting machine is controlled to perform synchronous processing according to the processing parameters, and the actual processing time of the processing path is detected in real time during the processing, and the cutting speed is adjusted based on the actual processing time and the corresponding theoretical processing time, including:

[0058] S310, obtaining the actual processing time of the most recently processed cutting segment, and determining the time deviation based on the actual processing time and the theoretical processing time of the cutting segment;

[0059] S320, determining a target processing time of the current cutting segment according to the theoretical processing time of the current cutting segment and the time deviation, determining a target speed according to the path length of the current cutting segment and the target processing time, and adjusting the cutting speed to the target speed; wherein the target speed does not exceed the maximum value of the cutting speed range.

[0060] By compensating for time deviations, it is ensured that adjustments can be made in actual processing to cope with slight changes in materials and machinery; it is ensured that cutting efficiency and accuracy are optimized under different material parameters and shape characteristics; by comparing the theoretical processing time and actual processing time between different cutting sections, the target speed is calculated, and within the processing capacity of the cutting machine, the force and speed of each cutting section are fine-tuned to adapt to changes in material properties.

[0061] As an improvement of the above embodiment, in S400, the remaining processing time of the two processing paths is detected in real time, and when the remaining processing time of any processing path is lower than the time threshold, the processing parameters of the two processing paths are dynamically adjusted based on the remaining processing time of the two processing paths until the processing of the two processing paths is completed, including:

[0062] S410, calculating the remaining processing time of the two processing paths respectively according to the set time interval;

[0063] It should be noted that the set time interval ranges from 0.1 second to 1 second, and the processing efficiency and synchronization are evaluated to ensure the synchronization of the processing process and reduce the processing time;

[0064] S420, determining whether the difference between the remaining processing time of the two processing paths is lower than the time deviation threshold, if so, executing S440; if not, slowing down the processing path with the longer remaining processing time according to the set speed step, and then executing S410;

[0065] S440, determining whether the processing of the two processing paths is completed, if so, ending; if not, executing S410.

[0066] By adjusting the cutting speed of the two processing paths, the two paths are ensured to be completed synchronously, avoiding processing errors caused by speed differences, and ultimately achieving efficient and accurate synchronous cutting. By dynamically adjusting the cutting speed, the progress differences of the two processing paths are effectively balanced to ensure the accuracy and efficiency of synchronous processing. The real-time monitoring and adjustment mechanism further optimizes the cutting process, improves product quality, and meets high-standard processing requirements.
