[0002] Aircraft are often accompanied by various types of noise during takeoff, flight, and landing. As a mainstream engine noise control method, acoustic lining nacelles effectively suppress noise by absorbing and dissipating noise waves based on the principle of Helmholtz resonators.

[0047] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0048] The main solution of the embodiment of the present application is: obtaining point error data based on the actual profile and theoretical profile of the target product; obtaining the tool length offset value based on the point error data; obtaining the tool compensation value based on the tool length offset value; completing the perforation control based on the drilling depth value and the tool compensation value; wherein the drilling depth value is obtained based on the first depth value, the second depth value, the third depth value and the fourth depth value, the first depth value is obtained based on the thickness of the target product, the second depth value is obtained based on the profile difference range of the target product, the third depth value is obtained based on the drilling depth error of the drill bit, and the fourth depth value is obtained based on the tool installation error.

[0049] Aircraft takeoff, flight, and landing are often accompanied by various types of noise, which has a serious impact on human hearing health. Therefore, the aircraft's noise reduction performance is a key indicator for airworthiness certification. The engine, as the aircraft's power plant, is the primary source of noise, so controlling engine noise is crucial for aircraft noise reduction. Currently, acoustic lining nacelles, as a mainstream engine noise control method, can effectively suppress noise by absorbing and dissipating noise waves based on the principle of Helmholtz resonators.

[0050] The acoustic lining structure in the acoustic lining nacelle is usually installed at the nacelle inlet and pipe outlet. It is a typical single-layer acoustic lining structure, composed of three layers of adhesive bonding and curing: a perforated panel on the inner surface, a resonance cavity, and a rigid backing plate. The perforated panel is made by preparing a large number of small holes with a diameter of only 0.75 to 1.6 mm in the acoustic lining hole area on the inner surface of the nacelle. The hole spacing is generally between 1.5 mm and 3.0 mm, and they are mostly arranged in an array. The number of holes often reaches hundreds of thousands. The huge number of holes poses a huge challenge to CNC machining. The traditional drilling process can only drill one hole in a single feed, which has low processing efficiency and long processing cycle. Usually, a drill shank is used to clamp multiple drill bits to drill holes simultaneously, so that multiple holes can be drilled in one feed, which significantly improves the drilling efficiency.

[0051] However, due to the complex hole-making conditions, there are many errors in the drilling process: the inner surface of the nacelle is a hyperbolic surface, the blank solidification deformation is large, and the product parts are large in size and the clamping positioning errors are large. It is easy to have non-drilling errors during drilling, which reduces the key product indicator of the perforation rate (the ratio of the area of ​​the hole to the area of ​​the sound lining hole surface), seriously affecting the quality of the sound lining product and reducing the noise reduction performance of the product.

[0052] To this end, the present application provides a solution. On the one hand, the actual surface and theoretical surface of the target product are used to obtain the point error data thereon to avoid excessive errors caused by the irregular structure on its curved surface. On this basis, the tool length offset value is obtained as a guide for tool compensation on the machine tool end; on the other hand, by regulating the drilling depth, errors introduced by the thickness of the product, product deformation, blank, etc., as well as the drilling depth and tool installation error of the drill bit of the group drilling are introduced, and the comprehensive drilling depth is obtained as a guide for the punching process to avoid hole-making errors such as incomplete drilling and missed drilling, thereby improving the control effect of group drilling for group hole punching and effectively improving the quality of hole making.

[0053] Referring to Figure 1, Figure 1 is a schematic diagram of the electronic device structure of the hardware operating environment involved in the embodiment of the present application.

Among them, the communication bus 102 is used to realize the connection and communication between these components. The user interface 104 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the user interface 104 may also include a standard wired interface and a wireless interface. The network interface 103 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (WIreless-FIdelity, WI-FI) interface). The memory 105 may optionally be a storage device independent of the aforementioned processor 101. The memory 105 may be a high-speed random access memory (RAM) memory, or a stable non-volatile memory (NVM), such as at least one disk memory. The processor 101 may be a general-purpose processor, including a central processing unit, a network processor, etc., or may be a digital signal processor, an application-specific integrated circuit, a field programmable gate array or other programmable logic device, a discrete gate or transistor logic device, or a discrete hardware component.

[0055] As shown in FIG1 , the memory 105 as a storage medium may include an operating system, a network communication module, a user interface module, and a group hole punching control device.

[0056] In the electronic device shown in Figure 1, the network interface 103 is mainly used for data communication with the network server; the user interface 104 is mainly used for data interaction with the user; the processor 101 and the memory 105 in this application can be set in the electronic device, and the electronic device calls the group hole perforation control device stored in the memory 105 through the processor 101, and executes the group hole perforation control method provided in the embodiment of this application.

[0057] Referring to FIG. 2 , based on the hardware device of the aforementioned embodiment, an embodiment of the present application provides a group hole perforation control method, comprising the following steps:

[0058] S10: Obtaining point error data based on the actual profile and theoretical profile of the target product.

[0059] During implementation, the target product is an acoustic liner structure requiring clustered holes. Figure 4 shows a typical target product, specifically the annular, hyperbolic surface structure of an engine nacelle air inlet. Due to the influence of the curved surface structure, the error on the target product's profile is non-uniform. Therefore, the error is determined by comparing the actual profile with the theoretical profile. It should be noted that due to the influence of the curved surface, the error is obtained using multiple measurement points set on the profile. These measurement points cover the target product's profile. Based on this, the normal deviation between the measured and theoretical values ​​of the product's profile at each measurement point is measured to obtain point error data.

[0060] S20: Obtain the tool length offset value according to the point error data.

[0061] In the specific implementation process, the tool length offset value is the basis for the adjustment of the machine tool end during the processing. Based on the point error data, the solution equation of the tool length offset value is constructed, and the tool length offset value can be solved to guide the tool compensation of the machine tool end. Specifically, according to the point error data, the tool length offset value is obtained, including:

[0062] According to the point error data, the solution equation of the tool length offset value is constructed;

[0063] The least square method is used to solve the equation and obtain the tool length offset value.

[0064] In the specific implementation process, the solution equation is constructed as follows: g(c)=min∑(cc i ) 2

[0065] Among them, c iThis refers to the normal deviation between the measured and theoretical values ​​of the product surface at each measurement point, i.e., the point error data. c, the solution to this equation, is the tool length offset, which can be solved using the least squares method, estimating the theoretical normal deviation. The least squares method minimizes the sum of squared errors to find the optimal function matching the data. This method can easily determine unknown data and minimize the sum of squared errors between the determined data and the actual data.

[0066] S30: Obtain the tool compensation value according to the tool length offset value.

[0067] S40: Complete the perforation control according to the drilling depth value and the tool compensation value; wherein the drilling depth value is obtained based on the first depth value, the second depth value, the third depth value and the fourth depth value, the first depth value is obtained based on the thickness of the target product, the second depth value is obtained based on the surface difference range of the target product, the third depth value is obtained based on the drilling depth error of the drill bit, and the fourth depth value is obtained based on the tool installation error.

[0068] In the specific implementation process, the tool compensation value is the compensation value of the machine tool end to the tool during processing, that is, the tool length offset that needs to be increased. The drilling depth value controls the processing error by measuring the errors in multiple aspects and introduces the thickness of the product to ensure the perforation effect. The drilling depth is obtained by summing the four depth values ​​and expressed as a p =δ1+δ2+δ3+δ4.

[0069] Where ap is the drilling depth value, δ1 is the first depth value, δ2 is the second depth value, δ3 is the third depth value, and δ4 is the fourth depth value. The parameter values ​​are shown in Figure 3. The above data can be used to guide the modification of the hole making program, and then the processing can be carried out according to the modified hole making program. Specifically, the method for obtaining each depth value is as follows:

[0070] In one embodiment, before completing the perforation control based on the drilling depth value and the tool compensation value, the group hole perforation control method further includes:

[0071] A first depth value is obtained according to the maximum thickness of the perforated panel stacking of the target product.

[0072] In a specific implementation process, the maximum thickness of the perforated panel stack is usually 110% of the nominal thickness of the panel, which is used as the first depth value to ensure that all hole positions can be drilled through during hole making.

[0073] In one embodiment, before completing the perforation control based on the drilling depth value and the tool compensation value, the group hole perforation control method further includes:

[0074] According to the measured value and theoretical value of the target product surface, the maximum difference and the minimum difference between the measured value and the theoretical value are obtained;

[0075] According to the maximum and minimum differences between the measured values ​​and the theoretical values, the surface difference range of the target product is obtained;

[0076] A second depth value is obtained according to the profile difference range.

[0077] In the specific implementation process, the profile difference range is the difference range between the measured value and the theoretical value of the hyperbolic surface product. It can be understood that due to the influence of the surface structure, the difference at each measurement point is different. Therefore, the maximum difference and the minimum difference between the measured value and the theoretical value can be obtained as the profile difference range, and then the maximum difference between the two is obtained as the second depth value to achieve full coverage of the profile error, that is, δ2=c max -c min , where c max is the maximum difference between the measured value and the theoretical value, c min is the minimum difference between the measured value and the theoretical value.

[0078] In one embodiment, before completing the perforation control based on the drilling depth value and the tool compensation value, the group hole perforation control method further includes:

[0079] According to the minimum virtual rectangular unit of the hole group arrangement, the length and width of the minimum virtual rectangular unit are obtained respectively;

[0080] According to the length and width of the minimum virtual rectangular unit, the longest distance between the drill bits in the first direction and the second direction are obtained respectively;

[0081] Obtaining a drilling depth error of the drill bit according to the curvature of the surface of the target product in the first direction and the second direction, and the longest distance between the drill bits in the first direction and the second direction, respectively;

[0082] A third depth value is obtained according to the drilling depth error of the drill bit.

[0083] In the specific implementation process, the length of the smallest virtual rectangular unit of the hole cluster arrangement is a and the width is b. The longest distance between the drill bits in the long direction, that is, the first direction, is A, which is an integer multiple of a. The longest distance between the drill bits in the width direction, that is, the second direction, is B, which is an integer multiple of b. Because the preparation quality of the hole cluster needs to be guaranteed, the third depth value in this embodiment should be the maximum drilling depth error, that is:

[0084] where R A is the surface curvature in the long direction, i.e. the first direction, R B is the curvature of the surface in the width direction, i.e. the second direction.

[0085] In one embodiment, before completing the perforation control based on the drilling depth value and the tool compensation value, the group hole perforation control method further includes:

[0086] The tool setting error is obtained based on the maximum difference between the drill bits in the drilling row;

[0087] A fourth depth value is obtained according to the tool installation error.

[0088] In the specific implementation process, there may be tool installation errors on the drill bit, such as errors caused by installation deviations, or tool breakage of some drill bits. In order to control these errors, the maximum difference between the drill bits in the drilling row is obtained, that is, the length difference between the longest drill bit and the shortest drill bit, that is, the fourth depth value δ4=l max -l min , where l max is the length of the longest drill bit, l min is the length of the shortest drill bit.

[0089] In this embodiment, the actual surface and theoretical surface of the target product are used to obtain the point error data thereon to avoid excessive errors caused by the irregular structure on its curved surface. On this basis, the tool length offset value is obtained as a guide for tool compensation on the machine tool end; on the other hand, by regulating the drilling depth, errors introduced by the thickness of the product, product deformation, blank, etc., as well as the drilling depth and tool installation error of the drill bit of the group drilling are introduced, and the comprehensive drilling depth is obtained as a guide for the punching process to avoid hole-making errors such as non-drilling and missed drilling, thereby improving the control effect of group drilling for group hole punching and effectively improving the quality of hole making.

[0090] Taking the target product shown in FIG4 as an example, this application is further explained:

[0091] The engine nacelle has an annular double-curvature surface structure for the air inlet, on which the acoustic lining holes are staggered. The nominal thickness of the panel is 1.2 mm, and the curvature radius R A =760mm, R B =1050mm, hole spacing a=4.3mm, b=3.6mm, drill bit arrangement with 9 drill bits, drill bit spacing A=21.5mm, B=28.8mm, relevant engineering parameter requirements are as follows:

[0092] First, after the product is stably clamped and held, the positional errors of most points on the actual surface of the hyperbolic product are measured. i ;

[0093] Measure the maximum error value c max =0.7192mm, minimum deviation value c min =-1.2688mm

[0094] Secondly, install the drill bit on the machine tool spindle and measure the length of each drill bit on the drill bit. j The measurement results are shown in Table 1-1.

[0095] Table 1-1

[0096] Among them, l max =8.62, l min =7.82

[0097] Then, calculate the drilling depth a p , modify the drilling depth of the hole making program;

[0098] δ1=1.2*110%=1.32mm;

[0099] δ2=c max -c min =1.988mm;

[0100] δ4=l max -l min =8.62-7.82mm=0.8mm

[0101] Then the drilling depth ap=δ1+δ2+δ3+δ4=1.32+1.988+0.406+0.8=4.514mm

[0102] The tool length offset c is calculated by the least squares method, and the equation g(c) = min∑(cc i ) 2 , the solution is c=0.5, correspondingly increase the tool compensation value at the machine tool end;

[0103] Finally, run the program to start processing and complete the control of drilling and drilling group holes.
