Description

Technical Field

[0001] The present invention relates to the technical field of electronic digital data processing, and in particular to a method and system for controlling the stability of coupled processing of nickel-titanium alloy components. Background Art

[0002] In the field of nickel-titanium alloy component processing, the special properties of nickel-titanium alloy will lead to problems such as poor processing stability and difficult to control surface quality during the processing of nickel-titanium alloy components, affecting the processing efficiency and product quality of nickel-titanium alloy components. Therefore, effectively controlling the quality of nickel-titanium alloy components during the processing and improving processing stability have become important issues that need to be urgently addressed in the current manufacturing field. Through targeted stability control methods, the impact of adverse factors can be effectively reduced, the processing quality and efficiency of nickel-titanium alloy components can be improved, and more reliable data support can be provided for high-precision processing.

[0003] The prior art, such as the invention patent with announcement number: CN111597661B, discloses a method for controlling the stability of coupled processing of aluminum alloy thin-walled components. The aluminum alloy powder is spread on the workbench, and the selected area is laser sintered by a laser. The process is repeated ten times according to the "powder spreading-sintering" link. The finite element method is used to obtain the dynamic parameters of the sintered metal sheet and the machine tool system. The milling dynamics differential equation in the state space form considering the regeneration effect is established, and the continuous time t in a cycle is expressed as a discrete time node. Finally, the state transfer matrix of two adjacent cutting cycles is established to judge the stability of the system. The critical axial cutting depth of machining instability during milling is obtained through theoretical calculation, and the two-dimensional stability limit diagram of the spindle speed and axial cutting depth is calculated. When milling the sintered metal sheet, the optimal vibration-free cutting parameters calculated by the Cotes numerical integration method are used to set the cutting amount to achieve stable cutting and maximum material removal efficiency.

[0004] Prior art, such as the invention patent announcement with announcement number: CN113591341B, discloses a method for optimizing the forging process of titanium alloy based on numerical simulation. Taking into account the differences in the rheological behaviors of titanium alloy materials at different temperatures and initial organizational states, its constitutive equations at different deformation stages are established. The temperature and stress field distributions of the material are calculated using the finite element method based on the thermophysical properties parameters of the material to be processed, the recrystallization and grain growth dynamics, and the heat transfer coefficient of the cooling medium as initial conditions and boundary definitions, and the heating, cooling, and deformation parameters of the material are determined, thereby optimizing the forging process.

[0005] In combination with the above scheme, it is found that currently in the field of nickel-titanium alloy component processing technology, usually only the processing process is monitored and analyzed. However, the nickel-titanium alloy component processing will be affected by the changes in the nickel-titanium alloy performance, which affects the processing accuracy and stability. The thermal effect and surface quality in the processing process cannot be effectively controlled, which may cause defects such as cracks and deformation on the processed surface, thereby causing a decrease in the mechanical properties of the nickel-titanium alloy component, affecting the final quality of the nickel-titanium alloy component. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a method and system for controlling the stability of coupled processing of nickel-titanium alloy components, which can effectively solve the problems involved in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a method for controlling the stability of coupled processing of nickel-titanium alloy components, including statistically processing historical data of coupled processing of nickel-titanium alloy components, and matching the configuration parameters of the coupled processing laser.

[0008] The configuration parameters of the coupled processing laser are transmitted to the central controller, and the central controller configures the parameters of the coupled processing laser.

[0009] The nickel-titanium alloy component is processed according to the configured coupled processing laser, the processing parameters of the nickel-titanium alloy component are collected, and the output power of the coupled processing laser is synchronously adjusted.

[0010] The quality of the processed NiTi alloy components is monitored to obtain the coupling processing results of the NiTi alloy components, and the coupling processing is optimized and adjusted.

[0011] Furthermore, the statistical nickel-titanium alloy component coupling processing historical data is processed, and the specific process is: the nickel-titanium alloy component coupling processing historical data includes the historical average laser power of the coupling processing laser, the historical average pulse frequency of the coupling processing laser, the historical average focal length of the coupling processing laser, the historical average laser wavelength of the coupling processing laser and the reflectivity of the nickel-titanium alloy.

[0012] Based on the historical data of coupled processing of nickel-titanium alloy components, the optimized processing benchmark value of coupled processing of nickel-titanium alloy components is obtained.

[0013] Furthermore, the matching obtains the configuration parameters of the coupled processing laser, and the specific process is: based on the optimized processing reference value of the coupled processing of the nickel-titanium alloy component.

[0014] The optimized processing reference values ​​of the coupled processing of the nickel-titanium alloy components are matched with the configuration parameters corresponding to each optimized processing reference value interval stored in the coupled processing database, and the configuration parameters corresponding to the interval of the optimized processing reference values ​​of the coupled processing of the nickel-titanium alloy components are counted and recorded as the configuration parameters of the coupled processing laser.

[0015] Furthermore, the nickel-titanium alloy component is processed according to the configured coupled processing laser, and the specific process is: using the configured coupled processing laser to emit a ring laser.

[0016] Based on a nickel-titanium alloy tube placed in an alloy tube engraved with a target pattern, a ring laser is controlled to move along the outer wall of the alloy tube engraved with the target pattern to process the nickel-titanium alloy component.

[0017] Furthermore, the specific process of collecting the processing parameters of the nickel-titanium alloy component is as follows: the processing parameters of the nickel-titanium alloy component include the surface temperature of the nickel-titanium alloy, the scanning speed of the coupled processing laser, the reflectivity of the nickel-titanium alloy and the laser spot diameter of the coupled processing laser.

[0018] The processing energy density value of NiTi alloy components was obtained based on comprehensive analysis of NiTi alloy component processing parameters.

[0019] Furthermore, the synchronous adjustment of the output power of the coupled processing laser comprises the following specific processes: based on the processing energy density value of the nickel-titanium alloy component, processing is performed to obtain the coupled processing laser adjustment result, and the coupled processing laser adjustment result includes executing the adjustment and not executing the adjustment.

[0020] The nickel-titanium alloy component processing energy density value is compared with the set nickel-titanium alloy component processing energy density threshold. If the nickel-titanium alloy component processing energy density value is lower than the set nickel-titanium alloy component processing energy density threshold, the coupled processing laser adjustment result is marked as executing adjustment; otherwise, the coupled processing laser adjustment result is marked as not executing adjustment.

[0021] Extract the coupling processing laser adjustment result. If the coupling processing laser adjustment result is not to perform adjustment, continue to perform coupling processing with the current coupling processing laser output power. If the coupling processing laser adjustment result is to perform adjustment, the difference between the nickel-titanium alloy component processing energy density threshold and the nickel-titanium alloy component processing energy density value is recorded as the nickel-titanium alloy component processing adjustment control value.

[0022] Match the nickel-titanium alloy component processing adjustment control value with the output power corresponding to each nickel-titanium alloy component processing adjustment control value interval stored in the coupled processing database, count the output power corresponding to the interval in which the nickel-titanium alloy component processing adjustment control value is located, record it as the output power of the coupled processing laser and perform adjustment.

[0023] Furthermore, the quality monitoring of the processed nickel-titanium alloy components is carried out, and the specific process is: extracting the average value of the processing energy density value of the nickel-titanium alloy components, recording it as the processing index value of the nickel-titanium alloy components, matching the processing index value of the nickel-titanium alloy components with the processing quality assessment interference factors corresponding to the processing index value intervals of each nickel-titanium alloy component stored in the coupled processing database, and counting the processing quality assessment interference factors corresponding to the interval in which the processing index value of the nickel-titanium alloy components is located, and recording them as processing quality assessment influencing factors.

[0024] The quality monitoring data of the nickel-titanium alloy component processing are counted, and the quality monitoring data of the nickel-titanium alloy component processing includes the average number of surface defect areas of the nickel-titanium alloy component, the average value of dimensional deviation, processing time and processing efficiency.

[0025] Based on the quality monitoring data of nickel-titanium alloy component processing, the quality assessment value of nickel-titanium alloy component processing is obtained by processing. According to the processing quality assessment influencing factors and combined with the quality assessment value of nickel-titanium alloy component processing, the comprehensive quality analysis characterization value of nickel-titanium alloy component processing is obtained by comprehensive processing.

[0026] Furthermore, the coupling processing optimization adjustment is specifically carried out as follows: comparing the quality comprehensive analysis characterization value of the nickel-titanium alloy component processing with the set quality comprehensive analysis characterization threshold value to obtain the nickel-titanium alloy component coupling processing result, and the nickel-titanium alloy component coupling processing result includes not performing coupling processing adjustment and performing coupling processing adjustment.

[0027] If the quality comprehensive analysis characterization value of the nickel-titanium alloy component processing is higher than or equal to the set quality comprehensive analysis characterization threshold, the nickel-titanium alloy component coupling processing result will be marked as not performing coupling processing adjustment, and the nickel-titanium alloy component coupling processing will continue with the current coupling processing parameters.

[0028] If the quality comprehensive analysis characterization value of the nickel-titanium alloy component processing is lower than the set quality comprehensive analysis characterization threshold, the nickel-titanium alloy component coupling processing result will be marked as executing coupling processing adjustment, and the difference between the quality comprehensive analysis characterization threshold and the quality comprehensive analysis characterization value of the nickel-titanium alloy component processing will be recorded as the coupling processing optimization reference value for the nickel-titanium alloy component processing.

[0029] The coupled processing optimization reference values ​​for nickel-titanium alloy component processing are matched with the coupled processing parameters corresponding to each coupling processing optimization reference value interval stored in the coupled processing database, and the coupled processing parameters corresponding to the interval in which the coupled processing optimization reference values ​​for nickel-titanium alloy component processing are located are counted and recorded as the coupled processing parameters for nickel-titanium alloy component processing, and the coupled processing optimization adjustment configuration is performed based on the coupled processing parameters for nickel-titanium alloy component processing.

[0030] Furthermore, the quality assessment value of the nickel-titanium alloy component processing is specifically analyzed under the following conditions:

[0031] Where, β represents the quality assessment value of nickel-titanium alloy component processing, τ 1 Represents the average number of surface defects of NiTi alloy components, μ 1 Indicates the correction factor corresponding to the average number of surface defect areas per unit, τ 2 Represents the average dimensional deviation of nickel-titanium alloy components, μ 2 Indicates the correction factor corresponding to the set average value of unit size deviation, τ 3 represents the processing time of NiTi alloy components, Δτ 3 Indicates the set reference processing time, τ 4 Indicates the processing efficiency of NiTi alloy components, Δτ 4 represents the set reference processing efficiency, and e represents a natural constant.

[0032] The second aspect of the present invention provides a nickel-titanium alloy component coupling processing stability control system, including: a coupling processing pre-configuration module for statistical processing of nickel-titanium alloy component coupling processing history data, and matching to obtain the configuration parameters of the coupling processing laser.

[0033] The parameter configuration module is used to transmit the configuration parameters of the coupled processing laser to the central controller, and the central controller performs parameter configuration on the coupled processing laser.

[0034] The processing flow analysis module is used to process the nickel-titanium alloy components according to the configured coupled processing laser, collect the processing parameters of the nickel-titanium alloy components, and synchronously adjust the output power of the coupled processing laser.

[0035] The optimization and adjustment module is used to monitor the quality of the processed nickel-titanium alloy components, obtain the coupled processing results of the nickel-titanium alloy components, and perform coupled processing optimization and adjustment.

[0036] The present invention has the following beneficial effects:

[0037] (1) The present invention provides a method for controlling the stability of coupled processing of nickel-titanium alloy components. First, the historical data of coupled processing is statistically processed to reduce the failure rate caused by improper parameter settings during the processing. Then, the processing parameters of the nickel-titanium alloy components are collected, and the output power of the coupled processing laser is synchronously adjusted to reduce the stability fluctuation during the processing. Finally, the quality of the processed nickel-titanium alloy components is monitored, and coupled processing optimization and adjustment are performed to improve the stability of the entire processing process.

[0038] (2) The present invention can effectively reduce the processing errors caused by improper laser configuration, improve the processing accuracy of NiTi alloy components, and reduce the quality fluctuation of NiTi alloy components caused by parameter fluctuations by configuring the parameters of the coupled processing laser. By fine-tuning the laser, the working state of the laser can be optimized and the overload of the laser can be reduced, thereby improving the coupled processing efficiency of NiTi alloy components and enhancing the coupled processing stability of NiTi alloy components.

[0039] (3) The present invention can better cope with the property changes of nickel-titanium alloy during the coupling processing process by synchronously adjusting the output power of the coupling processing laser, ensuring that the nickel-titanium alloy components receive optimal energy input during the processing, thereby reducing overheating or insufficient energy. Appropriate output power adjustment helps to evenly transfer heat energy, reduce local overheating, and improve the smoothness and precision of the coupled processing surface.

[0040] (4) The present invention performs coupling processing optimization and adjustment to achieve more precise heat control and make heat input more uniform. By optimizing the coupling processing flow, it can not only improve the coupling processing efficiency, enhance the efficiency of the processing process, but also reduce rework and repair caused by unstable processing, thereby effectively reducing the overall production cycle and cost, and ensuring that each batch of processed nickel-titanium alloy components can meet the same quality standards.

[0041] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] See also Figure 1As shown, an embodiment of the present invention provides a technical solution: a method for controlling the stability of coupled processing of a nickel-titanium alloy component, comprising statistically processing historical data of coupled processing of the nickel-titanium alloy component and matching the configuration parameters of the coupled processing laser.

[0048] The configuration parameters of the coupled processing laser are transmitted to the central controller, and the central controller configures the parameters of the coupled processing laser.

[0049] The nickel-titanium alloy component is processed according to the configured coupled processing laser, the processing parameters of the nickel-titanium alloy component are collected, and the output power of the coupled processing laser is synchronously adjusted.

[0050] The quality of the processed NiTi alloy components is monitored to obtain the coupling processing results of the NiTi alloy components, and the coupling processing is optimized and adjusted.

[0051] Specifically, statistics on the coupled processing history data of the nickel-titanium alloy components are processed, and the specific process is: the coupled processing history data of the nickel-titanium alloy components include the historical average laser power of the coupled processing laser, the historical average pulse frequency of the coupled processing laser, the historical average focal length of the coupled processing laser, the historical average laser wavelength of the coupled processing laser and the reflectivity of the nickel-titanium alloy.

[0052] It should be noted that the historical average pulse frequency of the coupled processing laser refers to the average frequency of the laser pulses emitted during the historical processing process, and the reflectivity of the nickel-titanium alloy refers to the reflection ratio of the laser energy on the surface of the nickel-titanium alloy. The laser power, pulse frequency, focal length, laser wavelength and reflectivity of the nickel-titanium alloy can be measured respectively using a power meter, a frequency meter, a laser beam analyzer, a wavelength meter and a reflectivity measuring device, and then the historical average laser power, historical average pulse frequency, historical average focal length, historical average laser wavelength and reflectivity of the coupled processing laser can be statistically obtained.

[0053] Based on the historical data of coupled processing of nickel-titanium alloy components, the optimized processing benchmark value of coupled processing of nickel-titanium alloy components is obtained.

[0054] It should be added that the optimized processing benchmark value of the coupling processing of NiTi alloy components is used to quantify the quality of the coupling processing of historical NiTi alloy components.

[0055] In this embodiment, the optimized processing reference value of the coupled processing of the nickel-titanium alloy component can be obtained by the following analysis method, and the specific analysis conditions are as follows:

[0056]

[0057] In the formula, α represents the optimized processing reference value of NiTi alloy component coupling processing, B 1 represents the historical average laser power of the coupled processing laser, ΔB1 Indicates the set reference laser power, B 2 represents the historical average pulse frequency of the coupled processing laser, ΔB 2 Indicates the set reference pulse frequency, B 3 represents the historical average focal length of the coupled processing laser, ΔB 3 Indicates the reference focal length, B 4 represents the historical average laser wavelength of the coupled processing laser, θ 1 Indicates the correction factor corresponding to the set unit laser wavelength, B 5 represents the reflectivity of NiTi alloy, θ 2 It represents the correction factor corresponding to the set unit reflectivity, and e represents a natural constant.

[0058] It should be noted that an increase in laser power may improve processing efficiency, but if the power is too high, it may cause material overheating, ablation, or more heat-affected zones, thereby reducing processing quality. The smaller the absolute value of the difference between the historical average laser power of the coupled processing laser and the reference laser power, the larger the optimized processing benchmark value. An increase in pulse frequency can increase processing accuracy, but if the pulse frequency is too high, it may lead to a decrease in material removal rate or unnecessary thermal effects. The smaller the absolute value of the difference between the historical average pulse frequency of the coupled processing laser and the reference pulse frequency, the larger the optimized processing benchmark value. A short focal length may result in a too small focus point. It is impossible to cover a larger processing area, and a focal length that is too long may cause the energy distribution to be too wide, reducing processing efficiency and accuracy. The smaller the absolute value of the difference between the historical average focal length of the coupled processing laser and the reference focal length, the larger the optimized processing benchmark value, and the shorter laser wavelength is more easily absorbed by the nickel-titanium alloy, thereby improving processing efficiency. Lasers with longer wavelengths will be reflected or transmitted by the nickel-titanium alloy material, reducing the energy coupling efficiency. The smaller the historical average laser wavelength, the larger the optimized processing benchmark value, and the nickel-titanium alloy with lower reflectivity is more likely to absorb the laser, thereby improving processing efficiency. The smaller the reflectivity, the larger the optimized processing benchmark value, and the higher the coupling processing quality of the nickel-titanium alloy component.

[0059] It should be added that, in the present embodiment, the correction factor corresponding to the preset unit laser wavelength and the correction factor corresponding to the unit reflectivity are obtained from the coupled processing database.

[0060] It needs to be explained that the correction factors corresponding to the unit laser wavelength and the unit reflectivity are respectively used to correct the influence of the historical average laser wavelength of the coupling processing laser and the reflectivity of the nickel-titanium alloy on the optimized processing benchmark value of the coupling processing of the nickel-titanium alloy component. These corresponding relationships are pre-set mapping relationships. The pre-set mapping relationships can match the input real-time nickel-titanium alloy component coupling processing history data with the correction factors in the coupling processing database to obtain the correction factors corresponding to the nickel-titanium alloy component coupling processing history data. The nickel-titanium alloy component coupling processing history data and the correction factors in the coupling processing database correspond one to one. For example, the historical average laser wavelength of the coupling processing laser and the reflectivity of the nickel-titanium alloy are respectively matched with the correction factors in the coupling processing database to obtain the correction factors corresponding to the unit laser wavelength and the correction factors corresponding to the unit reflectivity.

[0061] In this embodiment, the historical average laser power of the coupled processing laser, the historical average pulse frequency of the coupled processing laser, the historical average focal length of the coupled processing laser, the historical average laser wavelength of the coupled processing laser and the reflectivity of the nickel-titanium alloy are correlated and do not exist independently. For example, the historical average laser power and the historical average pulse frequency jointly determine the energy input and energy distribution characteristics of the laser, while the historical average focal length of the coupled processing laser affects the focusing effect of the laser, thereby affecting the interaction between the laser and the nickel-titanium alloy. The change in laser wavelength will directly affect the absorption characteristics of the nickel-titanium alloy. The efficiency of laser energy of different laser wavelengths being absorbed by the nickel-titanium alloy material is different, and the reflectivity of the nickel-titanium alloy is an important factor affecting the efficiency of laser energy transfer. When the reflectivity of the nickel-titanium alloy is high, the laser energy is easily reflected, thereby reducing the processing efficiency and precision. The optimized processing reference value for the coupled processing of the nickel-titanium alloy component is obtained through comprehensive analysis, and an optimized laser configuration parameter can be accurately obtained. The configuration parameter can achieve the best processing effect, thereby improving the processing quality and efficiency.

[0062] Specifically, the configuration parameters of the coupled processing laser are matched, and the specific process is: based on the optimized processing reference value of the coupled processing of the nickel-titanium alloy component.

[0063] The optimized processing reference values ​​of the coupled processing of the nickel-titanium alloy components are matched with the configuration parameters corresponding to each optimized processing reference value interval stored in the coupled processing database, and the configuration parameters corresponding to the interval of the optimized processing reference values ​​of the coupled processing of the nickel-titanium alloy components are counted and recorded as the configuration parameters of the coupled processing laser.

[0064] It should be added that the configuration parameters of the coupled processing laser include the scanning speed and laser spot diameter of the coupled processing laser.

[0065] It should be noted that the analysis of the coupled processing history data of the nickel-titanium alloy components can reflect the historical processing quality. At this time, if the original default scanning speed and laser spot diameter are used for control, the instability or deviation of the processing quality will be aggravated, and it will be unable to adapt to the changes in the actual material and processing environment. Therefore, it is necessary to configure the configuration parameters of the coupled processing laser according to the coupled processing history data of the nickel-titanium alloy components. Using the coupled processing history data of the nickel-titanium alloy components to adjust the scanning speed and laser spot diameter of the coupled processing laser can effectively reduce the problem of changes in the processing environment, thereby improving the control accuracy of the processing process, and ultimately optimizing the processing quality and product performance.

[0066] According to the historical data of coupled processing of NiTi alloy components, the configuration parameters of the coupled processing laser are analyzed and matched. Accurate configuration parameters help to improve the processing efficiency of NiTi alloy components, improve the coupled processing accuracy of NiTi alloy components, reduce surface defects and dimensional deviations of NiTi alloy components, thereby improving the overall quality of NiTi alloy components.

[0067] Specifically, the nickel-titanium alloy component is processed according to the configured coupled processing laser, and the specific process is: using the configured coupled processing laser to emit a ring laser.

[0068] Based on a nickel-titanium alloy tube placed in an alloy tube engraved with a target pattern, a ring laser is controlled to move along the outer wall of the alloy tube engraved with the target pattern to process the nickel-titanium alloy component.

[0069] It needs to be explained that Figure 3 The figure is an example of the processing process of a nickel-titanium alloy component. A core shaft (2) is placed in a nickel-titanium alloy tube (3), and then the nickel-titanium alloy tube (3) is placed in an alloy tube (4) engraved with a target pattern and fixed at the geometric center of a ring laser (1). The ring laser (1) moves along the core shaft (2) toward a predetermined position. The ring laser (1) can reach the nickel-titanium alloy surface through the gaps in the alloy tube (4) engraved with the target pattern, cut the nickel-titanium tube, and be absorbed on the surface without pattern gaps. In this way, a nickel-titanium alloy tube (3) with a target pattern can be obtained. On the basis of ensuring the performance of the nickel-titanium alloy tube (3), the cutting efficiency can be improved and the time cost of laser processing of nickel-titanium alloy can be reduced.

[0070] It should be added that the alloy tube engraved with the target pattern is made of tungsten steel. The target pattern is adjusted according to the specific performance of the product, and a tungsten steel core shaft must be added inside the nickel-titanium tube.

[0071] Specifically, the processing parameters of the nickel-titanium alloy component are collected, and the specific process is: the processing parameters of the nickel-titanium alloy component include the surface temperature of the nickel-titanium alloy, the scanning speed of the coupled processing laser, the reflectivity of the nickel-titanium alloy and the laser spot diameter of the coupled processing laser.

[0072] It should be noted that the surface temperature of the nickel-titanium alloy refers to the temperature reached on the surface of the nickel-titanium alloy component during the processing process, and the scanning speed of the coupled processing laser refers to the speed at which the ring laser moves on the processing surface. The surface temperature of the nickel-titanium alloy can be measured using an infrared thermal imager. The scanning speed of the coupled processing laser and the laser spot diameter of the coupled processing laser are obtained by matching the configuration parameters of the coupled processing laser.

[0073] The processing energy density value of NiTi alloy components was obtained based on comprehensive analysis of NiTi alloy component processing parameters.

[0074] It should be added that the energy density value of nickel-titanium alloy component processing is used to quantify the processing quality of nickel-titanium alloy components.

[0075] In this embodiment, the processing energy density value of the nickel-titanium alloy component can be obtained by the following analysis method, and the specific analysis conditions are as follows:

[0076]

[0077] Where, γ represents the energy density of nickel-titanium alloy component processing, C 1 Indicates the surface temperature of NiTi alloy, ΔC 1 Indicates the set reference surface temperature, C 2 represents the scanning speed of the coupled processing laser, ΔC 2 Indicates the set reference scanning speed, C 3 represents the reflectivity of NiTi alloy, Indicates the correction factor corresponding to the set unit reflectivity, C 4 represents the laser spot diameter of the coupled processing laser, It represents the correction factor corresponding to the set unit laser spot diameter, and e represents a natural constant.

[0078] It should be noted that the surface temperature of nickel-titanium alloy usually affects the material absorption rate and thermal conductivity during laser processing. When the surface temperature of nickel-titanium alloy increases, the absorption rate of the alloy may increase, resulting in more laser energy being absorbed by nickel-titanium alloy, thereby affecting the heat-affected zone of processing. Too high surface temperature of nickel-titanium alloy may lead to excessive heat diffusion, thereby reducing the energy density in a unit area. The greater the absolute value of the difference between the surface temperature of nickel-titanium alloy and the reference surface temperature, the greater the processing energy density value of nickel-titanium alloy components. Too fast scanning speed of the coupled processing laser may result in insufficient laser energy to effectively process the material, while too slow scanning speed of the coupled processing laser may cause overheating and thermal damage. The reflectivity of nickel-titanium alloy means that more laser energy is reflected rather than absorbed by the material. The smaller the reflectivity of nickel-titanium alloy, the greater the processing energy density value of nickel-titanium alloy components. The size of the laser spot diameter of the coupled processing laser affects the degree of focusing of the laser beam on the material surface. The smaller the laser spot diameter of the coupled processing laser, the greater the processing energy density value of the nickel-titanium alloy components, and the higher the coupled processing quality of the nickel-titanium alloy components.

[0079] It should be added that, in this embodiment, a preset correction factor corresponding to a unit reflectivity and a correction factor corresponding to a unit laser spot diameter are obtained from the coupled processing database.

[0080] It needs to be explained that the correction factors corresponding to the unit reflectivity and the unit laser spot diameter are respectively used to correct the influence of the reflectivity of the nickel-titanium alloy and the laser spot diameter of the coupled processing laser on the processing energy density value of the nickel-titanium alloy component. These corresponding relationships are pre-set mapping relationships. The pre-set mapping relationships can match the input real-time nickel-titanium alloy component processing parameters with the correction factors in the coupled processing database to obtain the correction factors corresponding to the nickel-titanium alloy component processing parameters. The nickel-titanium alloy component processing parameters correspond to the correction factors in the coupled processing database one by one. For example, the reflectivity of the nickel-titanium alloy and the laser spot diameter of the coupled processing laser are respectively matched with the correction factors in the coupled processing database to obtain the correction factors corresponding to the unit reflectivity and the correction factors corresponding to the unit laser spot diameter.

[0081] In this embodiment, the surface temperature of the nickel-titanium alloy, the scanning speed of the coupled processing laser, the reflectivity of the nickel-titanium alloy and the laser spot diameter of the coupled processing laser are correlated and do not exist independently. For example, the surface temperature of the nickel-titanium alloy not only affects the thermal conduction efficiency of the material, but also determines the absorption rate of the laser energy. The reflectivity determines the effective absorption degree of the laser energy. High reflectivity means that the surface of the nickel-titanium alloy may not be able to effectively absorb all the laser energy, thereby affecting the processing effect. The laser scanning speed is directly related to the processing heat input. Too fast scanning speed may lead to insufficient local heating, while too slow scanning speed may lead to overheating, thereby affecting the processing quality. The laser spot diameter determines the area of ​​laser energy distribution and affects the concentration of energy density. Comprehensive analysis can obtain the processing energy density value of the nickel-titanium alloy component, which can more accurately optimize the processing process of the nickel-titanium alloy.

[0082] Specifically, the output power of the coupled processing laser is synchronously adjusted, and the specific process is: based on the processing energy density value of the nickel-titanium alloy component, the coupled processing laser adjustment result is processed to obtain the coupled processing laser adjustment result, and the coupled processing laser adjustment result includes executing the adjustment and not executing the adjustment.

[0083] It needs to be explained that based on the processing energy density value of the nickel-titanium alloy components, the coupled processing laser adjustment results can improve the stability of the energy density during the coupled processing process, reduce the problems of overburning or insufficient processing, and improve the surface quality and overall performance of the nickel-titanium alloy components.

[0084] The nickel-titanium alloy component processing energy density value is compared with the set nickel-titanium alloy component processing energy density threshold. If the nickel-titanium alloy component processing energy density value is lower than the set nickel-titanium alloy component processing energy density threshold, the coupled processing laser adjustment result is marked as executing adjustment; otherwise, the coupled processing laser adjustment result is marked as not executing adjustment.

[0085] Extract the coupling processing laser adjustment result. If the coupling processing laser adjustment result is not to perform adjustment, continue to perform coupling processing with the current coupling processing laser output power. If the coupling processing laser adjustment result is to perform adjustment, the difference between the nickel-titanium alloy component processing energy density threshold and the nickel-titanium alloy component processing energy density value is recorded as the nickel-titanium alloy component processing adjustment control value.

[0086] Match the nickel-titanium alloy component processing adjustment control value with the output power corresponding to each nickel-titanium alloy component processing adjustment control value interval stored in the coupled processing database, count the output power corresponding to the interval in which the nickel-titanium alloy component processing adjustment control value is located, record it as the output power of the coupled processing laser and perform adjustment.

[0087] It should be noted that the analysis of the processing parameters of the NiTi alloy components can reflect the quality of the NiTi alloy components during the processing. If the quality of the NiTi alloy components is unqualified, controlling the output power of the coupling processing laser with the original default will result in unstable processing quality, overheating or insufficient heating, which may cause surface defects and even damage the microstructure of the NiTi alloy, affecting the final performance of the NiTi alloy components. Therefore, it is necessary to adjust the output power of the coupling processing laser according to the processing parameters of the NiTi alloy components. Real-time adjustment of the output power of the coupling processing laser can improve the quality stability during the processing, thereby reducing dimensional deviations and surface defects and improving the processing accuracy of the NiTi alloy components.

[0088] Specifically, the quality of the processed nickel-titanium alloy components is monitored, and the specific process is as follows: the average value of the processing energy density value of the nickel-titanium alloy components is extracted, recorded as the processing index value of the nickel-titanium alloy components, the processing index value of the nickel-titanium alloy components is matched with the processing quality assessment interference factors corresponding to the processing index value intervals of each nickel-titanium alloy component stored in the coupled processing database, and the processing quality assessment interference factors corresponding to the intervals in which the processing index values ​​of the nickel-titanium alloy components are located are counted, recorded as processing quality assessment influencing factors.

[0089] It should be added that extracting the average value of the processing energy density of nickel-titanium alloy components can evaluate the quality of the entire processing process of nickel-titanium alloy components. The processing index value of nickel-titanium alloy components reflects the comprehensive result of factors such as energy distribution, thermal effect, and mechanical change during the processing, which will directly or indirectly affect the processing quality. The processing quality assessment interference factor is obtained by matching the processing index value of nickel-titanium alloy components, which can identify possible quality interference factors in the processing process, thereby evaluating the processing quality more effectively.

[0090] The quality monitoring data of the nickel-titanium alloy component processing are counted, and the quality monitoring data of the nickel-titanium alloy component processing includes the average number of surface defect areas of the nickel-titanium alloy component, the average value of dimensional deviation, processing time and processing efficiency.

[0091] It should be noted that an automated visual inspection system and an optical measuring instrument are usually used to measure the average number of surface defect areas and the average size deviation of nickel-titanium alloy components, respectively. The production management system can statistically obtain the processing time and efficiency of the nickel-titanium alloy components.

[0092] It should be supplemented that the quality assessment value of nickel-titanium alloy component processing is used to quantify the quality level of nickel-titanium alloy component processing.

[0093] Based on the quality monitoring data of nickel-titanium alloy component processing, the quality assessment value of nickel-titanium alloy component processing is obtained by processing. According to the processing quality assessment influencing factors and combined with the quality assessment value of nickel-titanium alloy component processing, the comprehensive quality analysis characterization value of nickel-titanium alloy component processing is obtained by comprehensive processing.

[0094] It should be noted that using the product of the processing quality assessment influencing factor and the quality assessment value of the nickel-titanium alloy component processing as a comprehensive quality analysis characterization value of the nickel-titanium alloy component processing will help improve the quality of the nickel-titanium alloy component processing and further adjust the processing process.

[0095] Specifically, the quality assessment value of nickel-titanium alloy component processing, the specific analysis conditions are:

[0096]

[0097] Where, β represents the quality assessment value of nickel-titanium alloy component processing, τ 1 Represents the average number of surface defects of NiTi alloy components, μ 1 Indicates the correction factor corresponding to the average number of surface defect areas per unit, τ 2 Represents the average dimensional deviation of nickel-titanium alloy components, μ 2 Indicates the correction factor corresponding to the set average value of unit size deviation, τ 3 represents the processing time of NiTi alloy components, Δτ 3 Indicates the set reference processing time, τ 4 Indicates the processing efficiency of NiTi alloy components, Δτ 4 represents the set reference processing efficiency, and e represents a natural constant.

[0098] It should be noted that the greater the average number of surface defects of the nickel-titanium alloy component, the more defects there are on the surface of the nickel-titanium alloy component, which usually means the worse the processing quality, and the smaller the quality assessment value of the nickel-titanium alloy component processing; the larger the average value of the dimensional deviation of the nickel-titanium alloy component, the greater the difference between the actual size and the design size of the nickel-titanium alloy component, and the smaller the quality assessment value of the nickel-titanium alloy component processing; too long processing time for the nickel-titanium alloy component may mean that there are problems or low efficiency in the processing process; the greater the difference between the absolute value of the processing time of the nickel-titanium alloy component and the reference processing time, the smaller the quality assessment value of the nickel-titanium alloy component processing; higher processing efficiency of nickel-titanium alloy components usually means that the production process is smooth and the quality is relatively stable, but if the processing efficiency of the nickel-titanium alloy component is too high, it may mean that some details or precision are not fully controlled, thereby affecting the quality of the nickel-titanium alloy component; the greater the difference between the absolute value of the processing efficiency of the nickel-titanium alloy component and the reference processing efficiency, the smaller the quality assessment value of the nickel-titanium alloy component processing.

[0099] It should be added that, in this embodiment, the correction factor corresponding to the preset average number of unit surface defect areas and the correction factor corresponding to the average value of unit size deviation are obtained from the coupled processing database.

[0100] It needs to be explained that the correction factors corresponding to the average number of surface defect areas per unit and the average size deviation per unit are respectively used to correct the degree of influence of the average number of surface defect areas and the average size deviation of nickel-titanium alloy components on the quality assessment value of nickel-titanium alloy component processing. These corresponding relationships are pre-set mapping relationships. The pre-set mapping relationships can match the input real-time quality monitoring data of nickel-titanium alloy component processing with the correction factors in the coupled processing database to obtain the correction factors corresponding to the quality monitoring data of nickel-titanium alloy component processing. The quality monitoring data of nickel-titanium alloy component processing corresponds to the correction factors in the coupled processing database one by one. For example, the average number of surface defect areas and the average size deviation of nickel-titanium alloy components are respectively matched with the correction factors in the coupled processing database to obtain the correction factors corresponding to the average number of surface defect areas per unit and the average size deviation per unit.

[0101] In this embodiment, the average number of surface defect areas, the average size deviation, the processing time and the processing efficiency of the nickel-titanium alloy component are correlated and do not exist independently. For example, the average number of surface defect areas and the average size deviation are usually directly related to the processing accuracy and quality. A higher average number of surface defect areas and a larger average size deviation will cause the nickel-titanium alloy component to fail to meet the design requirements and require more corrections or reprocessing, thereby increasing the processing time of the nickel-titanium alloy component and reducing the processing efficiency of the nickel-titanium alloy component. Comprehensive analysis can obtain the quality evaluation value of the nickel-titanium alloy component processing, which can more accurately evaluate the processing quality of the nickel-titanium alloy component and the optimization of process control.

[0102] Specifically, the coupling processing optimization adjustment is performed, and the specific process is: comparing the quality comprehensive analysis characterization value of the nickel-titanium alloy component processing with the set quality comprehensive analysis characterization threshold; if the quality comprehensive analysis characterization value of the nickel-titanium alloy component processing is higher than or equal to the set quality comprehensive analysis characterization threshold, then continuing to perform the nickel-titanium alloy component coupling processing with the current coupling processing parameters.

[0103] If the quality comprehensive analysis characterization value of the nickel-titanium alloy component processing is lower than the set quality comprehensive analysis characterization threshold, the difference between the quality comprehensive analysis characterization threshold and the quality comprehensive analysis characterization value of the nickel-titanium alloy component processing is recorded as the coupled processing optimization reference value of the nickel-titanium alloy component processing.

[0104] The coupled processing optimization reference values ​​for nickel-titanium alloy component processing are matched with the coupled processing parameters corresponding to each coupling processing optimization reference value interval stored in the coupled processing database, and the coupled processing parameters corresponding to the interval in which the coupled processing optimization reference values ​​for nickel-titanium alloy component processing are located are counted and recorded as the coupled processing parameters for nickel-titanium alloy component processing, and the coupled processing optimization adjustment configuration is performed based on the coupled processing parameters for nickel-titanium alloy component processing.

[0105] It should be noted that the coupling processing parameters for processing nickel-titanium alloy components include the pulse width and focal length of the coupling processing laser.

[0106] It should be added that the analysis of the quality monitoring data of the nickel-titanium alloy component processing can reflect the processing quality of the nickel-titanium alloy components. If the processing quality is unqualified and the subsequent processing control is carried out with the original default coupling processing parameters of the nickel-titanium alloy component processing, it may cause instability in the processing quality. Therefore, it is necessary to make corresponding adjustments to the coupling processing parameters of the nickel-titanium alloy component processing based on the quality monitoring data of the nickel-titanium alloy component processing.

[0107] It should be noted that a method and system for controlling the coupled processing stability of a nickel-titanium alloy component also includes a coupled processing database for storing a first parameter set, a second parameter set and a third parameter set obtained by analyzing historical data.

[0108] The first parameter set includes reference laser power, reference pulse frequency, reference focal length, correction factor corresponding to unit laser wavelength, correction factor corresponding to unit reflectivity, and configuration parameters corresponding to each optimized processing reference value interval.

[0109] The second parameter set includes reference surface temperature, reference scanning speed, correction factor corresponding to unit reflectivity, correction factor corresponding to unit laser spot diameter, nickel-titanium alloy component processing energy density threshold and output power corresponding to each nickel-titanium alloy component processing adjustment control value interval.

[0110] The third parameter set includes the processing quality assessment interference factor corresponding to the processing index value interval of each nickel-titanium alloy component, the correction factor corresponding to the average number of unit surface defect areas, the correction factor corresponding to the average unit dimensional deviation, the reference processing time, the reference processing efficiency, the quality comprehensive analysis characterization threshold and the coupling processing parameters corresponding to each coupling processing optimization reference value interval.

[0111] like Figure 2 The second aspect of the present invention provides a nickel-titanium alloy component coupling processing stability control system, including: a coupling processing pre-configuration module, which is used to collect and process the historical data of the nickel-titanium alloy component coupling processing and match the configuration parameters of the coupling processing laser.

[0112] The parameter configuration module is used to transmit the configuration parameters of the coupled processing laser to the central controller, and the central controller performs parameter configuration on the coupled processing laser.

[0113] The processing flow analysis module is used to process the nickel-titanium alloy components according to the configured coupled processing laser, collect the processing parameters of the nickel-titanium alloy components, and synchronously adjust the output power of the coupled processing laser.

[0114] The optimization and adjustment module is used to monitor the quality of the processed nickel-titanium alloy components, obtain the coupled processing results of the nickel-titanium alloy components, and perform coupled processing optimization and adjustment.
