[0022] The names of the messages or information exchanged between multiple devices in the embodiments of the present invention are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0023] In related technologies, some high-end CNC systems provide vibration suppression functions, but they lack flexibility and user-friendliness, making it difficult to make real-time adjustments based on specific working conditions. The complex setting process requires users to have a high level of technical skills, which increases the threshold for use.

[0024] In response to the problems existing in the above-mentioned related technologies, this embodiment provides a vibration suppression control method, device, electronic device and storage medium.

[0025] like Figure 1 As shown, an embodiment of the present invention provides a vibration suppression control method, which is applied to a CNC machine tool, wherein the CNC machine tool includes a spindle. The vibration suppression control method includes: Step S100, obtaining a frequency parameter value and an intensity parameter value, wherein the frequency parameter value is used to control the frequency of change of the spindle speed, and the intensity parameter value is used to control the amplitude of change of the spindle speed; Step S200: When the frequency parameter value is greater than a first preset frequency value and less than or equal to a second preset frequency value, and the intensity parameter value is greater than a first preset intensity value and less than or equal to a second preset intensity value, generating a vibration suppression control signal according to the frequency parameter value and the intensity parameter value; Step S300: adjusting the spindle speed according to the vibration suppression control signal.

[0026] Specifically, the frequency parameter determines how often vibration suppression occurs, determining the number of times the vibration suppression operation is performed per unit time. When the frequency parameter is set to a higher value, the CNC system can adjust the spindle speed multiple times per unit time to offset vibration. The frequency parameter's value range can be set based on the machine tool's spindle speed range to ensure that the vibration suppression function does not exceed the physical limitations of the mechanical system or cause unnecessary wear. The frequency parameter range should be neither too large nor too small. Too many operation options may increase user selection difficulty, while too few may not meet the needs of different situations. The intensity parameter determines the amplitude of the spindle speed change during vibration suppression, that is, the degree to which the spindle speed is adjusted to offset vibration. The intensity parameter can be set from 1 to 4, which can be thought of as four speed levels: the amplitude of the change in level 1 is ±5% of the current speed, the amplitude of the change in level 2 is ±10%, the amplitude of the change in level 3 is ±15%, and the amplitude of the change in level 4 is ±20%. The value of the intensity parameter should not be too large. If the intensity of vibration suppression is too large (such as exceeding 20%), it may cause abnormal wear of mechanical parts such as transmission belts or couplings. It should not be too small either. If the intensity is set too small (such as less than 5%), it may not be able to effectively offset medium and high intensity vibrations, resulting in poor suppression effect. The first preset frequency value can be set to 0, and the second preset frequency value can be set to 6. When the frequency parameter value is greater than the first preset frequency value and less than or equal to the second preset frequency value (that is, the frequency parameter is greater than 0 and less than or equal to 6); the first preset intensity value is set to 0 and the second preset intensity value is set to 4 (that is, the intensity parameter is greater than 0 and less than or equal to 4), a vibration suppression control signal is generated according to the frequency parameter value and the intensity parameter value, and the spindle speed is adjusted according to the vibration suppression control signal to achieve vibration suppression.

[0027] In this embodiment, the frequency parameter determines the frequency of vibration suppression, and the intensity parameter determines the magnitude of the spindle speed change during vibration suppression. A vibration suppression control signal is generated based on the frequency and intensity parameters to adjust the spindle speed. This effectively reduces vibration caused by resonance without changing the original machining path, achieving vibration suppression. Different frequency and intensity parameter values ​​can be selected for vibration suppression based on different machining materials, tool types, and workpiece shapes. By adjusting the frequency and intensity parameter values, users can flexibly select the most appropriate vibration suppression based on actual machining requirements. This allows users to easily and intuitively select the appropriate vibration suppression, eliminating the need for in-depth knowledge of complex control logic or programming. By simply determining the frequency and intensity parameter values, the vibration suppression effect can be quickly adjusted, significantly improving work efficiency and the convenience of machining vibration suppression. By setting the value ranges for the frequency and intensity parameters, control signals are generated only when the parameter values ​​meet the requirements, avoiding invalid or erroneous signal generation and improving system reliability and stability.

[0028] Optionally, generating the vibration suppression control signal according to the frequency parameter value and the intensity parameter value includes: Acquire a time signal, and perform a sine function operation on the product of the frequency corresponding to the frequency parameter value and the time signal to obtain a sine modulated signal; Modulating the amplitude coefficient corresponding to the intensity parameter value according to the sinusoidal modulation signal to obtain a spindle speed compensation amount; The vibration suppression control signal is generated according to the spindle speed compensation amount.

[0029] Specifically, a time signal can be acquired through a clock or interpolator within the CNC system. The frequency parameter value is converted to a corresponding frequency. The acquired time signal is multiplied by the converted frequency, and the resulting product is subjected to a sine function calculation to generate a sinusoidal adjustment signal. Appropriate frequency parameter values ​​can be selected based on different machining scenarios and workpiece characteristics to generate a sinusoidal modulation signal of the corresponding frequency. For example, when machining thin-walled parts, a higher frequency parameter value can be selected to generate a high-frequency sinusoidal modulation signal, more precisely suppressing high-frequency vibrations. When machining large, rigid parts, a lower frequency parameter value can be selected to generate a low-frequency sinusoidal modulation signal, adapting to the lower vibration frequency characteristics. The intensity parameter value is converted to a corresponding amplitude coefficient. The spindle speed compensation value at each moment is obtained by multiplying the value of the sinusoidal modulation signal at each moment by the amplitude coefficient. The intensity parameter value and, therefore, the amplitude coefficient can be determined based on the vibration intensity during machining, ensuring that the spindle speed compensation value matches the actual vibration suppression requirements. For example, when cutting harder materials, stronger vibrations may be generated. A larger intensity parameter value can be selected to achieve a larger amplitude coefficient, thereby increasing the spindle speed compensation and more effectively suppressing vibrations. When cutting softer materials, a smaller intensity parameter value can meet the vibration suppression requirements and avoid unnecessary impacts on the machining process caused by excessive spindle speed adjustment. The spindle speed compensation amount is superimposed on the spindle base speed. That is, the spindle speed compensation amount at the corresponding moment is added to the spindle base speed to generate a corresponding vibration suppression control signal to adjust the spindle speed, thereby achieving vibration suppression.

[0030] In this optional embodiment, the sinusoidal function operation can generate a smooth, continuous and periodically changing sinusoidal modulation signal, which is conducive to the smooth adjustment of the spindle speed, avoiding the rapid change of the spindle speed due to the sudden change of the signal, thereby reducing the impact on the motor spindle, extending the service life of the equipment, and also helping to improve the stability of the processing process. By dynamically adjusting the frequency through the frequency parameter, it is possible to adapt to the vibration characteristics of different materials, tools and working conditions, thereby improving the control accuracy and adaptability. By controlling the amplitude coefficient through the intensity parameter, it can meet the mild suppression requirements of mild vibrations and can also cope with severe vibrations. Therefore, according to the frequency parameter and the intensity parameter, a vibration suppression control signal is generated to adjust the spindle speed. Under the premise of not changing the original processing path, the vibration phenomenon caused by resonance is effectively weakened, the processing stability and surface finish are significantly improved, and the life of the tool is further extended.

[0031] Optionally, when the frequency parameter value is less than the first preset frequency value or greater than the second preset frequency value, controlling the frequency parameter value to be adjusted to a default frequency parameter value; And / or, when the intensity parameter value is less than or equal to the first preset intensity value, or greater than the second preset frequency value, controlling the intensity parameter value to be adjusted to a default intensity parameter value.

[0032] Specifically, in common processing scenarios and workpiece types, the frequency value that can provide a better vibration suppression effect in most cases can be set as the default frequency parameter value, and the intensity value that can provide a better vibration suppression effect can be set as the default intensity parameter value. When the frequency parameter value is obtained, it is determined whether the frequency parameter is within the preset range. When the frequency parameter is not within the preset range, that is, the frequency parameter is less than the first preset frequency value or greater than the second frequency value, the frequency parameter is adjusted to the default frequency parameter value. When the intensity parameter value is obtained, it is determined whether the intensity parameter is within the preset range. When the intensity parameter is not within the preset range, that is, the intensity parameter is less than or equal to the first preset intensity value or greater than the second intensity value, the intensity parameter is adjusted to the default intensity parameter value.

[0033] In this optional embodiment, by monitoring the frequency parameter value and adjusting it to the default frequency parameter value, instability caused by the parameter exceeding the valid range can be prevented. If the frequency is set too high, more vibration suppression operations are performed per unit time, and the spindle speed is adjusted frequently, which may cause increased wear of the spindle and related mechanical parts. By setting a reasonable default value, it is possible to quickly restore the stable state when the parameter exceeds the expected range, prevent the negative effects caused by over-compensation or under-compensation, and improve the reliability of the vibration suppression control device. Even if the user accidentally enters an incorrect parameter value, it can be adjusted to the default value to avoid equipment abnormality or reduced processing quality due to misoperation.

[0034] Optionally, when the frequency parameter value is equal to the first preset frequency value, the intensity parameter value is controlled to be adjusted to the first preset intensity value, wherein the first preset frequency value and the first preset intensity value are both zero.

[0035] Optionally, when the frequency parameter value is equal to the first preset frequency value and the intensity parameter value is equal to the first preset intensity value, the vibration suppression control signal is stopped from being generated.

[0036] Specifically, when the acquired frequency parameter value is equal to the first frequency parameter, the intensity parameter value is forced to be adjusted to the first preset intensity value, that is, when the frequency parameter value is equal to 0, the intensity parameter value is controlled to be equal to 0. When the frequency parameter is equal to the first preset frequency value and the intensity parameter is equal to the first preset intensity value, it is determined that no vibration suppression operation is required under the current conditions, the vibration suppression is turned off, the generation of the vibration suppression control signal is stopped, the spindle speed is no longer dynamically adjusted, and the original setting state remains unchanged. If the intensity parameter value is not adjusted to the first intensity parameter value when the frequency parameter is equal to the first preset frequency value, that is, the frequency parameter is equal to 0, and the intensity parameter value is not forced to be equal to 0, a speed compensation amount may still be generated according to the non-zero intensity parameter value in an attempt to suppress vibration, which may cause unnecessary fluctuations in the spindle speed and affect the stability of the machining process.

[0037] In this optional embodiment, when the frequency parameter value is equal to the first frequency parameter value, the control intensity parameter value is adjusted to the first intensity parameter value, thereby avoiding incorrect compensation caused by not adjusting the intensity parameter value when the vibration suppression function is turned off, which in turn causes abnormal speed adjustment, reduces the potential risk of operational errors, and improves the reliability and stability of the entire system. During the semi-finishing or finishing stages, if the user believes that the current processing task does not require additional vibration suppression measures, or wishes to optimize the processing effect by manually controlling the spindle speed, the frequency parameter can be adjusted to the first frequency parameter value to turn off the vibration suppression function and ensure that the spindle operates stably at the reference speed.

[0038] Optionally, when the frequency parameter value and the intensity parameter value are not acquired, the vibration suppression control signal is generated according to the default frequency parameter value and the default intensity parameter value.

[0039] Specifically, when the vibration suppression control device is enabled and the frequency parameter and intensity parameter input by the user are not obtained, a vibration suppression control signal is generated based on the default frequency parameter values ​​and default intensity parameter values, thereby adjusting the spindle speed to achieve vibration suppression. It can be configured that if the frequency parameter values ​​and intensity parameter values ​​are not obtained within a preset time interval, the frequency parameter is adjusted to the default frequency parameter value, and the intensity parameter is adjusted to the default intensity parameter value.

[0040] In this optional embodiment, when the frequency parameter value and the intensity parameter value are not obtained, the default frequency parameter value and the default intensity parameter value are used to generate the control signal to ensure that the processing process is uninterrupted, thereby avoiding processing stagnation due to parameter loss and improving production efficiency. When the user is unfamiliar with the system operation and turns on the vibration suppression control device without confirming the frequency parameter value and the intensity parameter value, or when the processing needs to be started quickly in an emergency, the vibration suppression control signal is generated according to the default frequency parameter value and the default intensity parameter value, which reduces the impact of incorrect operation on system operation and processing accuracy, ensures that even when no specific parameters are input, the processing quality can be guaranteed to a certain extent, and reduces the scrapping of workpieces due to vibration.

[0041] Optionally, the first preset frequency value and the second preset frequency value are incremented by a first preset interval, and the first preset intensity value and the second preset intensity value are incremented by a second preset interval.

[0042] Specifically, when setting the preset frequency parameter value range, the increment interval between the first and second preset frequency values ​​is determined. For example, if the first preset frequency value is set to 0, the second preset frequency value is set to 6, and the increment interval of the frequency parameter is set to 1, the frequency parameter values ​​can be 1, 2, 3, 4, 5, and 6. Users can select appropriate frequency parameter values ​​within this incrementing sequence based on processing requirements. During the roughing stage, a lower frequency value (such as 1 or 2) can be selected to achieve more gentle spindle speed changes; during the finishing stage, a higher frequency value (such as 5 or 6) can be selected to more precisely suppress vibration. When setting the preset frequency parameter value range, the increment interval between the first and second preset intensity values ​​is determined. For example, if the first preset intensity value is set to 0, the second preset intensity value is set to 4, and the increment interval of the intensity parameter is set to 1, the intensity parameter values ​​can be 1, 2, 3, and 4.

[0043] In this optional embodiment, the use of fixed intervals makes frequency parameter selection intuitive and easy to understand, allowing users to quickly adjust vibration suppression based on their specific needs without complex calculations or in-depth technical knowledge. By setting clear intensity levels and their corresponding speed variations, users can control the extent of spindle speed changes, thereby more effectively suppressing vibration.
