Description

Technical Field

[0001] This application relates to the field of water-guided laser processing technology, and in particular to a method and apparatus for processing water-guided laser curves based on curvature adaptive variable voltage amplitude-frequency. Background Technology

[0002] Water-guided laser processing technology utilizes high-speed micro-water jets as the laser transmission medium. The laser undergoes total internal reflection at the interface between the water jet and the air, propagating along the water jet. It combines the advantages of high laser energy density and the cooling and scouring effect of water jets, showing broad application prospects in precision processing in aerospace, semiconductor, medical device and other fields.

[0003] To achieve controllable deflection of the water jet direction, electric field deflection technology has been introduced into the field of water-guided laser processing. Existing electric field deflection schemes are mostly static calibration or open-loop control of a single deflection angle; at the same time, existing electric field deflection control generally uses constant voltage amplitude and driving frequency, which leads to a mismatch between the deflection response speed and curve changes on curve segments with different radii of curvature, making it difficult to guarantee the consistency and repeatability of curve processing.

[0004] Therefore, existing technologies suffer from problems such as mismatch between deflection response and curve geometry, large trajectory tracking errors, and poor surface quality consistency in curve processing. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, this application provides a method for processing water-guided laser curves based on curvature adaptive variable voltage amplitude-frequency, so as to solve the problems existing in the background art.

[0006] In a first aspect, this application provides a curvature-adaptive variable voltage amplitude-frequency water-guided laser curve processing method, comprising: acquiring curvature radius data at each point on the water-guided laser processing path; establishing a control mapping model between the curvature radius and deflection voltage parameters based on the curvature radius data; wherein the deflection voltage parameters include voltage amplitude and driving frequency; taking the curvature radius of the current processing point as input, obtaining a target voltage amplitude and a target driving frequency that match the curve characteristics corresponding to the current curvature radius through the control mapping model; converting the target voltage amplitude and the target driving frequency into driving signals and outputting them to the deflection electrode array to dynamically adjust the deflection voltage parameters and control the water beam to complete the deflection scanning processing along a preset curve trajectory.

[0008] In one possible implementation, establishing a control mapping model between the radius of curvature and deflection voltage parameters based on the radius of curvature data includes: conducting calibration experiments under processing conditions of fixed water pressure, nozzle diameter, and electrode spacing to determine the optimal voltage amplitude and optimal driving frequency corresponding to different radii of curvature, which serve as the basic data for the control mapping model; and obtaining a physical correlation between the deflection angle and the voltage amplitude through the calibration experiments. And based on this physical correlation, a matching rule between the radius of curvature and the voltage amplitude is determined; where, For the deflection angle, For calibration coefficients, The voltage amplitude is used as the reference value. The matching rules are integrated into the control mapping model to ensure that the control mapping model satisfies the following: the smaller the radius of curvature, the larger the required deflection angle, and the voltage amplitude is negatively correlated with the radius of curvature; the larger the rate of change of the radius of curvature, the higher the deflection response requirement, and the driving frequency is positively correlated with the rate of change of the radius of curvature.

[0009] In one possible implementation, a look-ahead control step is also included. The look-ahead control step includes: calculating the look-ahead window length for the section of the machining path where the radius of curvature changes, to determine the trigger position for advance adjustment; when the machining position reaches the look-ahead window, within a preset time period before the inflection point of the radius of curvature change arrives, adjusting the voltage amplitude and / or drive frequency in advance to the target parameters that match the radius of curvature at the inflection point, according to the control mapping model, in order to eliminate hysteresis caused by inertia; wherein, the target parameters include the target voltage amplitude and the target drive frequency.

[0010] In one possible implementation, the length of the lookout window is calculated as follows: ;in, Forward window length, The current feed rate, This is a preset time period.

[0011] In one possible implementation, a deflection angle closed-loop correction step is also included; the deflection angle closed-loop correction step includes: real-time detection of the actual deflection angle of the water jet, comparing the actual deflection angle with the target deflection angle to obtain the angle deviation: ;in, For angular deviation, This is the actual deflection angle. The target deflection angle is defined. When the angle deviation exceeds a preset threshold, a PID closed-loop correction is applied to the voltage amplitude based on the angle deviation to ensure that the actual trajectory of the water jet remains consistent with the preset curve. The correction amount satisfies the following: ;in, This is the voltage amplitude correction amount. For angular deviation, This is the proportionality coefficient. The integral coefficient is... These are the differential coefficients. For time, This is the differential symbol.

[0012] Secondly, this application provides a curvature-adaptive variable voltage amplitude-frequency water-guided laser curve processing device, comprising: an acquisition module for acquiring curvature radius data at various points along the water-guided laser processing path; an establishment module for establishing a control mapping model between the curvature radius and deflection voltage parameters based on the curvature radius data; wherein the deflection voltage parameters include voltage amplitude and driving frequency; an acquisition module for acquiring a target voltage amplitude and a target driving frequency that match the curve characteristics corresponding to the current curvature radius through the control mapping model, using the curvature radius of the current processing point as input; and an adjustment module for converting the target voltage amplitude and target driving frequency into driving signals and outputting them to the deflection electrode array to dynamically adjust the deflection voltage parameters and control the water beam to complete the deflection scanning processing along a preset curve trajectory.

[0013] Thirdly, embodiments of this application provide a curvature-adaptive variable voltage amplitude-frequency water-guided laser curve processing server, including a memory and a processor; the memory is used to store computer-executable instructions; the processor is used to execute the computer-executable instructions to implement the method described in the first aspect or any possible implementation of the first aspect.

[0014] Fourthly, embodiments of this application provide a computer-readable storage medium storing executable instructions, which, when executed by a computer, enable the method described in the first aspect or any possible implementation thereof.

[0015] The beneficial effects of this application are as follows: By establishing a control mapping model between the radius of curvature, voltage amplitude, and driving frequency, this application achieves adaptive dynamic adjustment of the deflection voltage parameters according to the geometric characteristics of the path. Compared with the response lag or overshoot caused by the constant voltage / frequency in the prior art, this application can automatically increase the voltage amplitude and driving frequency according to the drastic changes in the curve curvature, ensuring that the response speed of the deflection system and the electrophoretic force fully match the curve change requirements. Because the deflection voltage parameters and the curvature of the processing path are precisely linked, the water jet can follow the preset curve trajectory in real time and accurately, effectively eliminating trajectory deviations caused by untimely parameter adjustment. Through adaptive voltage amplitude control, this application avoids abrupt changes in processing marks or overcutting phenomena caused by response mismatch in the curvature change section, ensuring the stability and continuity of the entire curve processing section. Ultimately, this significantly reduces the roughness of the processed surface, and the hole wall or cutting edge quality is uniform and excellent, effectively solving the problem of poor surface quality consistency in the prior art.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] This application provides a method for processing water-conducting laser curves based on curvature adaptive variable voltage amplitude-frequency, such as... Figure 1 As shown, the method includes steps S101 to S104. Wherein, Figure 1 This is merely one execution order shown in the embodiments of this application, and does not represent the only execution order for a curvature-adaptive variable voltage amplitude-frequency water-guided laser curve processing method. Where the final result can be achieved, Figure 1 The steps shown can be performed in parallel or in reverse order.

[0022] S101: Collect the radius of curvature data of each point on the water-guided laser processing path.

[0023] Collect the radius of curvature data at various points along the water-guided laser processing path, including the following:

[0024] A water-guided laser processing path is generated based on the 3D model of the workpiece, and point-by-point sampling is performed at intervals of less than or equal to 0.01 mm to collect the radius of curvature data of each point on the water-guided laser processing path.

[0025] Specifically, CAM software (a type of computer-aided manufacturing software) can generate a water-guided laser processing path offline based on the workpiece's 3D model, and sample each point at intervals less than or equal to 0.01 mm to calculate and collect the radius of curvature value corresponding to each point on the path, generating a radius of curvature-path position mapping table that is pre-stored in the control system; or, through a high-speed vision inspection module or laser displacement sensor integrated into the processing head, the radius of curvature of the current processing point can be collected online in real time during the processing, with a detection accuracy of not less than 0.01 mm, so as to achieve dynamic acquisition of radius of curvature data.

[0026] In this embodiment, the processing object is a nickel-based high-temperature alloy turbine blade with a thickness of 2mm. The curved cooling hole path to be processed includes three typical curvature radius sections: a straight section (curvature radius of infinity), a transition arc section (curvature radius of 1-3mm), and a sharp-angle arc section (curvature radius of ≤0.5mm). Specifically, after generating the processing path based on the three-dimensional model of the turbine blade, the curvature radius is calculated point by point at intervals of 0.01mm to form a complete path curvature distribution map, which provides a data basis for subsequent voltage amplitude-frequency adaptive adjustment.

[0027] S102: Based on the radius of curvature data, establish a control mapping model between the radius of curvature and the deflection voltage parameters. The deflection voltage parameters include voltage amplitude and driving frequency.

[0028] Based on the radius of curvature data, a control mapping model between the radius of curvature and the deflection voltage parameters is established, including the following:

[0029] Calibration experiments were conducted under fixed water pressure, nozzle diameter, and electrode spacing to determine the optimal voltage amplitude and optimal driving frequency corresponding to different radii of curvature, which served as the basic data for the control mapping model.

[0030] Specifically, a set of preset radius of curvature values ​​is selected. Through experiments, the optimal voltage amplitude required for the water jet to accurately track the curve trajectory corresponding to each radius of curvature was determined one by one. and optimal drive frequency .in, This refers to the serial number of the experimental sample. This is the total number of samples in the calibration experiment.

[0031] Specifically, this application employs a four-electrode surround copper electrode system, capable of generating controllable electric fields in the X and Y directions respectively. The electrode control method involves adjusting the voltage difference between the X-direction electrode pairs to control the deflection of the water jet in the X direction, and adjusting the voltage difference between the Y-direction electrode pairs to control the deflection of the water jet in the Y direction, thereby achieving arbitrary directional deflection and scanning of the water jet within a two-dimensional plane. The electrode spacing is set to 3mm. The insulation breakdown voltage of this electrode system has been measured to be 18kV. To ensure system safety, a maximum threshold voltage amplitude is set. The maximum threshold voltage amplitude should not exceed 80% of the insulation breakdown voltage to avoid inter-electrode breakdown discharge. Simultaneously, the voltage-deflection angle response curve and frequency-response time relationship of the electrode-water jet system are pre-calibrated to clarify the correspondence between voltage and deflection angle, and frequency and response speed. Furthermore, calibration coefficients are obtained through calibration experiments. The calibration coefficient represents the water jet deflection angle corresponding to the square of a unit voltage, and can be obtained by fitting experimental data using the least squares method.

[0032] The calibration experiment confirmed that the deflection angle and voltage amplitude are physically correlated. And based on this physical correlation, a matching rule between the radius of curvature and the voltage amplitude is determined. For the deflection angle, For calibration coefficients, This represents the voltage amplitude.

[0033] Will get Data points are stored in the control system to form a three-dimensional mapping table of radius of curvature, voltage amplitude, and drive frequency. Matching rules are then incorporated into the control mapping model. At the same time, the interpolation or fitting method of the model is supplemented to cover the radius of curvature values ​​on all processing paths (any one of the following can be used: table lookup method combined with linear interpolation, piecewise linear function method, or polynomial fitting method). Finally, the control mapping model satisfies the following correlation.

[0034] The matching rules are incorporated into the control mapping model to satisfy the following: the smaller the radius of curvature, the larger the required deflection angle, and the voltage amplitude is negatively correlated with the radius of curvature; the larger the rate of change of the radius of curvature, the higher the deflection response requirement, and the driving frequency is positively correlated with the rate of change of the radius of curvature.

[0035] Specifically, the smaller the radius of curvature (the sharper the curve), the larger the required deflection angle of the water jet. Therefore, the voltage amplitude is negatively correlated with the radius of curvature, so as to provide a stronger electrophoretic force through a higher voltage amplitude to drive the water jet to turn rapidly. The greater the rate of change of the radius of curvature (the more drastic the change of the curve trajectory), the higher the requirements for the dynamic response of the deflection system. Therefore, the driving frequency is positively correlated with the rate of change of the radius of curvature, so as to enhance the response speed of the deflection system.

[0036] S103: Using the radius of curvature of the current processing point as input, the target voltage amplitude and target driving frequency that match the curve characteristics corresponding to the current radius of curvature are obtained through the control mapping model.

[0037] S104: Converts the target voltage amplitude and target driving frequency into driving signals and outputs them to the deflection electrode array to dynamically adjust the deflection voltage parameters and control the water jet to complete the deflection scanning process along the preset curve trajectory.

[0038] Specifically, corresponding control commands are generated, and the target voltage amplitude and target driving frequency are sequentially processed through D / A conversion and power amplification before being output to the deflection electrode array. By dynamically adjusting the deflection voltage parameters (voltage amplitude and driving frequency) applied to the water jet in real time, the magnitude of the electrophoretic force on the water jet and the dynamic response speed of the deflection system are changed, thereby precisely controlling the water jet to complete the deflection scanning process along a preset curve trajectory. The voltage amplitude adjustment range is 0 to... , The voltage shall not exceed 80% of the insulation breakdown voltage, with a typical value of 5kV–15kV and an adjustment accuracy of not less than 0.1%FS. The adjustment range of the driving frequency is determined to be 10Hz to 5kHz based on the frequency response characteristics of the electrode-water jet system. In curve segments with drastic curvature changes, the frequency can be increased to a higher frequency range to ensure the processing accuracy of different curvature curve segments.

[0039] This application also includes forward control steps.

[0040] The forward control measures include the following.

[0041] For sections of the machining path where the radius of curvature changes, the length of the look-ahead window is calculated to determine the trigger position for advance adjustment.

[0042] When the processing position reaches the look-ahead window, within a preset time period before the inflection point of the radius of curvature change, the voltage amplitude and / or drive frequency are adjusted in advance to match the target parameters that match the radius of curvature at the inflection point, according to the control mapping model, in order to eliminate hysteresis caused by inertia. The target parameters include the target voltage amplitude and the target drive frequency.

[0043] The calculation methods for the lookout window length include: .in, Forward window length, The current feed rate, This is a preset time period.

[0044] Specifically, preset time period The value can range from 0.5ms to 5ms.

[0045] In this embodiment, a preset time period is determined based on the response characteristics of the deflection system. The value is 2ms (corresponding to the system response time constant). ,satisfy ); feed rate The length of the lookahead window is calculated. It is 0.01mm.

[0046] Meanwhile, in this embodiment, the control mapping model adopts a piecewise mapping method, specifically: when the radius of curvature is ≥3mm, the reference voltage... Drive frequency ; 1mm ≤ radius of curvature < 3mm, voltage Drive frequency When the radius of curvature is <1mm, the voltage Drive frequency .

[0047] This application also includes a deflection angle closed-loop correction step.

[0048] The deflection angle closed-loop correction steps include the following.

[0049] The actual deflection angle of the water jet is detected in real time, and compared with the target deflection angle to obtain the angle deviation. .in, For angular deviation, This is the actual deflection angle. The deflection angle is determined by the target.

[0050] When the angle deviation exceeds the preset threshold, the voltage amplitude is corrected using a PID closed-loop method based on the angle deviation to ensure that the actual trajectory of the water jet is consistent with the preset curve, and the correction amount satisfies: .in, This is the voltage amplitude correction amount. For angular deviation, This is the proportionality coefficient. The integral coefficient is... These are the differential coefficients. For time, This is the differential symbol.

[0051] Specifically, the preset threshold can be ±0.5°. The PID parameters can be tuned using the Ziegler-Nichols tuning method (an engineering tuning method for PID controller parameters) or pre-calibrated based on the system response characteristics; in this embodiment, closed-loop correction uses PID control, and the parameters are set... It is 0.8. It is 0.05. The value is 0.01, and the closed-loop control bandwidth is no less than 3-5 times the deflection drive frequency to ensure that fast and stable trajectory correction can still be achieved in sections with drastic curvature changes.

[0052] Specifically, this application can complete look-ahead parameter pre-adjustment 2ms before the path inflection point, dynamically update voltage amplitude and waveform parameters, and precisely drive the deflection electrode output. The water jet of this application can achieve a hysteresis-free response along a preset curved trajectory. The final results achieve: a trajectory tracking error ≤ ±2.5μm, a hole wall surface roughness Ra=0.08μm, and no heat-affected zone. Compared to traditional constant voltage solutions (such as a constant 7kV), this application significantly improves processing efficiency.

[0053] This application also provides a curvature-adaptive variable voltage amplitude-frequency water-guided laser curve processing device 200, such as... Figure 2 As shown, the device includes: a data acquisition module 201, a data establishment module 202, an acquisition module 203, and an adjustment module 204.

[0055] The module 202 is used to establish a control mapping model between the radius of curvature and the deflection voltage parameters based on the radius of curvature data. The deflection voltage parameters include voltage amplitude and driving frequency.

[0056] The acquisition module 203 is used to obtain the target voltage amplitude and target driving frequency that match the curve features corresponding to the current curvature radius through the control mapping model, using the curvature radius of the current processing point as input.

[0057] The adjustment module 204 is used to convert the target voltage amplitude and target driving frequency into driving signals and output them to the deflection electrode array to dynamically adjust the deflection voltage parameters and control the water jet to complete the deflection scanning process along the preset curve trajectory.
