[0032] Figure 2 This is the second schematic flowchart of the remanufacturing spray-coated workpiece processing method provided in the embodiments of the present invention.

[0033] Figure 3 This is a schematic diagram of the structure of the electronic device provided in an embodiment of the present invention. Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention 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 invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0035] Remanufactured spray-coated workpieces are new workpieces obtained by coating the surface of existing workpieces, achieving performance improvement or repair and remanufacturing. The coating thickness of remanufactured spray-coated workpieces is often relatively thin, around 1 mm. Due to its thinness and limited adhesion strength between the coating and the workpiece surface, the processing technology differs from that of workpieces made of uniform material. This invention addresses the limitations of coating thickness and adhesion strength between remanufactured spray-coated workpieces by proposing a processing technology suitable for them. Specifically, at different processing stages, different processing parameter adjustment strategies are provided based on the unique properties of remanufactured spray-coated workpieces (thin coating thickness, limited adhesion strength), enabling adaptive processing and ultimately obtaining high-quality remanufactured spray-coated workpieces.

[0036] The following is combined Figures 1-2 The remanufacturing method for spray-coated workpieces of the present invention is described. Figure 1 An exemplary schematic diagram of one of the process flow diagrams of the remanufacturing spray-coated workpiece processing method provided in an embodiment of the present invention is shown, such as... Figure 1 As shown, the method includes the following steps 101 to 102.

[0037] Step 101: In the roughing stage, adjust the processing parameters of the processing equipment with the constraint that the vibration amplitude of the remanufactured sprayed workpiece is less than the first preset threshold.

[0038] The coating on remanufactured spray-coated workpieces is made by applying a mixture of powdered materials to the workpiece surface via thermal spraying. Besides the uneven physical structure of the coating surface causing processing vibrations, the uneven distribution of hard particles within the coating material also contributes to these vibrations. This means that the vibration amplitude of remanufactured spray-coated workpieces is relatively large during the roughing stage. Since the coating thickness is thin, severe vibrations can affect the processing accuracy of remanufactured spray-coated workpieces, potentially leading to dimensions and shape that fail to meet processing requirements. To ensure the normal processing of remanufactured spray-coated workpieces, this invention implements real-time monitoring of the vibration amplitude during the roughing stage, controlling the vibration within a certain range to avoid its impact on processing accuracy.

[0039] It should be noted that the above-mentioned processing usually refers to processing using machining methods such as turning, milling, lathe, and milling machine.

[0040] Step 102: In the semi-finishing stage, adjust the processing parameters of the processing equipment with the constraint that the cutting force on the remanufactured sprayed workpiece is less than the second preset threshold.

[0041] This embodiment considers the limited thickness of the coating and the limited bonding strength between the coating and the workpiece surface. In the semi-finishing stage, the distance between the machined surface and the bonding layer between the coating and the workpiece surface is closer than in the roughing stage. Therefore, the magnitude of the cutting force on the machined surface has a significant impact on the bonding condition between the coating and the workpiece surface. In other words, if the cutting force is too large in the semi-finishing stage, the risk of damage to the bonding surface between the coating and the workpiece surface increases, and in severe cases, the coating may detach from the workpiece surface. Based on this, this embodiment needs to ensure that the cutting force on the remanufactured coated workpiece can be withstood by the bonding strength between the coating and the workpiece surface during the semi-finishing stage. Therefore, the cutting force on the machined surface of the workpiece is controlled within a certain range (i.e., less than a second preset threshold) during the semi-finishing stage.

[0042] It should be noted that after removing the surface inhomogeneity of the coating during the roughing stage, the material distribution inside the coating becomes compact and uniform, and the resulting machining vibration is no longer the main factor affecting the machining process. Therefore, in the semi-finishing stage, the main machining parameter adjustment strategy is to control the cutting force on the workpiece surface within a certain range (i.e., less than the second preset threshold).

[0043] In one example embodiment, Figure 2 This is an exemplary schematic diagram of a remanufacturing spray-coated workpiece processing method provided in an embodiment of the present invention, such as... Figure 2 As shown, based on the above embodiments, the method further includes: step 103, in the finishing stage, adjusting the processing parameters of the processing equipment with the constraint that the temperature of the remanufactured sprayed workpiece surface is less than a third preset threshold.

[0044] It should be noted that during the finishing stage, high-speed cutting generates significant heat, exacerbating residual stress in the material and leading to more surface thermal modification issues. To avoid residual stress and changes in workpiece surface properties, this embodiment prioritizes controlling the temperature parameter of the machined surface during the finishing stage, keeping it within a certain range (i.e., below a third preset threshold) to prevent excessively high temperatures from altering the properties of the machined surface.

[0045] In one example embodiment, due to machining allowance limitations, if there is no finishing allowance and semi-finishing can meet the surface quality requirements such as machining roughness, semi-finishing can be directly used as the final machining stage, i.e., no finishing stage is set. In this case, during the semi-finishing stage, in addition to adjusting the machining parameters of the processing equipment to ensure that the cutting force on the remanufactured sprayed workpiece is less than a second preset threshold, it is also necessary to adjust the machining parameters of the processing equipment to ensure that the temperature of the surface of the remanufactured sprayed workpiece is less than a third preset threshold. That is, in this stage, it is necessary to ensure that the cutting force on the workpiece can be withstood by the bonding strength between the coating and the workpiece surface, and also to avoid excessive temperature that would change the properties of the workpiece surface.

[0046] It should be noted that the machining parameters involved in all the above embodiments include cutting speed and depth of cut. Vibration amplitude, cutting force, and temperature are all acquired by corresponding measurement sensors. The temperature measurement sensor can be a non-contact sensor, which can be installed in any suitable location, as long as the temperature of the workpiece's machined surface can be measured. Vibration measurement sensors and cutting force measurement sensors can be installed on the workpiece's fixture, or in other locations, as long as the corresponding vibration amplitude or cutting force can be measured; this invention does not impose any limitations on this.

[0047] In one example embodiment, step 101 above, adjusting the processing parameters of the processing equipment with the constraint that the vibration amplitude of the remanufactured sprayed workpiece is less than a first preset threshold, may specifically include the following steps: acquiring vibration amplitude data of the remanufactured sprayed workpiece and determining whether the vibration amplitude data is less than the first preset threshold; if the vibration amplitude is not less than the first preset threshold, adjusting the processing parameters, acquiring the vibration amplitude data of the remanufactured sprayed workpiece after the processing parameters are adjusted again, and determining whether the vibration amplitude data is less than the first preset threshold, until the vibration amplitude data is less than the first preset threshold, and then stopping the adjustment of the processing parameters.

[0048] Similarly, in an example embodiment, step 102 above, adjusting the processing parameters of the processing equipment with the constraint that the cutting force on the remanufactured sprayed workpiece is less than the second preset threshold, may specifically include the following steps: acquiring the cutting force data on the remanufactured sprayed workpiece and determining whether the cutting force data is less than the second preset threshold; if the cutting force is not less than the second preset threshold, adjusting the processing parameters, acquiring the cutting force data on the remanufactured sprayed workpiece after the processing parameters are adjusted again, and determining whether the cutting force data is less than the second preset threshold, until the vibration amplitude data is less than the second preset threshold, and then stopping the adjustment of the processing parameters.

[0049] In one example embodiment, step 103 above, which uses the constraint that the temperature of the remanufactured sprayed workpiece surface is less than a third preset threshold, adjusts the processing parameters of the processing equipment. Specifically, this may include the following steps: acquiring the temperature of the remanufactured sprayed workpiece surface and determining whether the temperature is within the third preset threshold; if the temperature is not within the third preset threshold, adjusting the processing parameters, acquiring the surface temperature data of the remanufactured sprayed workpiece after the processing parameters are adjusted again, and determining whether the surface temperature data is less than the third preset threshold, until the surface temperature data is less than the third preset threshold, at which point the adjustment of the processing parameters is stopped.

[0050] It should be noted that the above-mentioned process of adjusting the machining parameters is a feedback adjustment process. That is, the machining parameters are adjusted based on the collected vibration amplitude, cutting force or temperature. If the collected vibration amplitude, cutting force or temperature is not less than the corresponding preset value, the machining parameters are adjusted. After the machining parameters are adjusted, the vibration amplitude, cutting force or temperature is collected again to determine whether it is less than the corresponding preset value. If it is still greater than the corresponding preset threshold, the machining parameters are adjusted again until the collected vibration amplitude, cutting force or temperature is less than the corresponding preset value, at which point the adjustment of the machining parameters stops.

[0051] The first preset threshold, the second preset threshold, and the third preset threshold in the embodiments of the present invention are all determined based on actual processing requirements and actual processing experience.

[0052] The following section uses the example of adjusting machining parameters based on cutting force feedback to describe the details of adjusting machining parameters in the above embodiments.

[0053] During processing, the cutting force value of the remanufactured sprayed workpiece is collected in real time, and it is determined whether the cutting force value is less than the second preset threshold. If the cutting force value is less than the second preset threshold, processing continues with the current processing parameters. If the cutting force value is greater than or equal to the second preset threshold, the cutting speed and cutting depth are adjusted, such as reducing the cutting speed or reducing the cutting depth.

[0054] In one example embodiment, taking cutting force as an example, the system can store a curve or table showing the corresponding adjustment relationship between machining parameters and cutting force values. Specifically, the adjustment magnitude of the machining parameters can be determined based on the difference between the actual measured value of the cutting force and a second preset threshold. For example, if the actual measured value of the cutting force is 1.5 times the second preset threshold, then the machining parameters will be reduced by 1.5 times. Of course, this example uses a linear proportional adjustment, but adjustments can also be made according to a curve relationship based on the actual situation.

[0055] In one example embodiment, a fixed adjustment amount can also be set. Again, taking cutting force as an example, when the actual measured value of the cutting force is greater than a second preset threshold, the machining parameters (cutting depth or cutting speed) are reduced by a fixed value. Then, the cutting force is measured again. If the current actual measured value of the cutting force is still greater than the second preset threshold, the machining parameters are reduced by a fixed value again, until the actual measured value of the cutting force is less than the second preset threshold. Of course, this fixed adjustment amount can also be in a stepped form. For example, if the second preset threshold is 200N, then intervals such as (200N, 220N), (200N, 240N), and (240N, 260N) can be set. When the actual measured value of the cutting force is in the interval (200N, 220N), the first fixed adjustment amount is used to reduce the machining parameters. When the actual measured value of the cutting force is in the interval (200N, 240N), the second fixed adjustment amount is used to reduce the machining parameters. It can be understood that the second fixed adjustment amount is greater than the first fixed adjustment amount. Similarly, when the actual measured value of the cutting force is in the range (240N, 260N), the machining parameters are reduced by a third fixed adjustment amount, which is greater than the second fixed adjustment amount.

[0056] It should be noted that when adjusting machining parameters, you can adjust only the depth of cut, only the cutting speed, or both. For example, if the actual measured value of the cutting force is 1.5 times the second preset threshold, then you can reduce the cutting speed by 1.5 times, or reduce the depth of cut by 1.5 times, or reduce both the cutting speed and the depth of cut by 0.75 times respectively.

[0057] In one example embodiment, taking cutting force as an example, after adjusting the cutting force to less than the second preset threshold using the method described in the previous embodiment, in order to balance efficiency and other factors and avoid excessively reducing the cutting depth or cutting speed, the cutting depth or cutting speed can be increased slightly to ensure that the machining efficiency is appropriately improved without the cutting force exceeding the second preset threshold. Of course, after slightly increasing the cutting depth or cutting speed, it is also necessary to collect the current cutting force and analyze whether it is less than the second preset threshold. If it is less than the second preset threshold, the current machining parameters are kept unchanged, or the cutting depth or cutting speed is further increased slightly, and the current cutting force is collected and analyzed again to see if it is less than the second preset threshold. If the current cutting force is greater than the second preset value, the machining parameters before the most recent slight increase in cutting depth or cutting speed are used for machining.

[0058] In this embodiment, the number of small adjustments can be one or multiple times. The specific magnitude or change value involved in the small adjustments can be set based on experience and actual conditions. This invention does not impose any restrictions on this.

[0059] It should be noted that the adjustment methods for machining parameters in the roughing stage can refer to the adjustment methods for machining parameters in the semi-finishing stage, i.e., the detailed methods for adjusting machining parameters based on vibration amplitude can refer to the detailed methods for adjusting machining parameters based on cutting force. However, the adjustment methods for machining parameters in the finishing stage cannot be completely referenced from the adjustment methods for machining parameters in the semi-finishing stage, i.e., the detailed methods for adjusting machining parameters based on the surface temperature cannot be completely referenced from the detailed methods for adjusting machining parameters based on cutting force. The main reason is that the finishing stage has requirements for machining accuracy and surface quality. Therefore, when adjusting machining parameters based on the surface temperature, the impact of changes in machining parameters on machining accuracy and quality must be considered. The adjustment of machining parameters needs to ensure that the temperature of the machined surface is controlled below the third preset threshold, while also ensuring that the machining accuracy and surface quality of the workpiece meet the set requirements.

[0060] Specifically, one can refer to the detailed method of adjusting machining parameters based on cutting force to adjust machining parameters based on the surface temperature. It is necessary to pre-determine the range of machining parameters that ensures machining accuracy and surface quality. Before adjusting the machining parameters based on the surface temperature, it is necessary to determine whether the adjusted machining parameters are within the aforementioned range. If not, the adjustment amount of the machining parameters needs to be re-determined. Of course, other methods can also be used to achieve a balance between surface temperature and machining accuracy and surface quality; this invention does not limit this approach.

[0061] In one example embodiment, taking a remanufactured sprayed workpiece with a thickness of about 1 mm as an example, the entire processing technology may include one roughing, one semi-finishing and one finishing; or the entire processing technology may include only one roughing and one semi-finishing.

[0062] The embodiments of the present invention will be described in detail below with reference to specific examples.

[0063] CNC systems use G-code for rapid workpiece machining. The generation of G-code relies on the setting and instruction transmission of the CNC machining control algorithm. This algorithm has an adaptive adjustment function, capable of calculating and adjusting based on signal feedback from vibration, cutting force, and temperature sensors during machining, achieving efficient CNC machining under G-code execution. Specifically, the CNC machining control algorithm described in the previous example is the one that adjusts machining parameters based on vibration amplitude, cutting force, and temperature.

[0064] The coating thickness of remanufactured sprayed workpieces is only about 1mm. To achieve fast and high-quality processing, the ideal approach is to optimize the chemical steps, which mainly include roughing, semi-finishing, and finishing.

[0065] (1) The first roughing is mainly to eliminate the non-uniformity of the workpiece surface (cutting depth 0.2mm~0.3mm), and is usually carried out by turning, milling, lathe, milling machine and other machining methods. The main manifestation is the influence of vibration. The non-uniformity of the workpiece surface is monitored by vibration measurement sensor, and the analysis results are fed back to the control algorithm so that the control algorithm can make corresponding adaptive adjustments.

[0066] (2) The second semi-finishing is to further refine the surface roughness and dimensional accuracy of the workpiece. The cutting depth is 0.1mm~0.2mm. During this process, the bonding strength of the coating has the most significant impact. A cutting force sensor is used to monitor this and feed the results back to the control algorithm for corresponding adjustments.

[0067] (3) The cutting depth of the third finishing process is (0.05mm~0.1mm). This is the last machining process, and a high-speed cutting speed is used. Significant heat is generated during the machining process, which exacerbates the generation of residual stress in the material and is accompanied by more surface thermal modification problems. In view of these situations, an industrial ultra-high-definition lens and an infrared temperature sensor are used to monitor the machining process. The signal is fed back to the control algorithm for adaptive adjustment to meet the machining process requirements.

[0068] Throughout the entire machining process, the CNC machining control algorithm can make corresponding adjustments to the CNC machining process according to the specific circumstances of each machining step, thereby enabling the workpiece to achieve the expected technical indicators through rapid CNC machining.

[0069] The remanufacturing spray-coated workpiece processing method provided in this invention is an intelligent processing flow. During the processing, the main factors of the processing are monitored and analyzed, and the results are fed back to the control algorithm in real time. The control algorithm then adaptively adjusts the CNC machine tool processing parameters to achieve intelligent and rapid processing of the remanufactured workpiece. The engineering implementation of this invention will efficiently reduce remanufacturing processing steps and improve efficiency. The adaptive control based on key processing signals further ensures high-quality completion of the processing.

[0070] This invention also provides a remanufacturing spray-coated workpiece processing system, comprising: a CNC machining equipment, a vibration measurement sensor, a cutting force measurement sensor, and a temperature measurement sensor. The vibration measurement sensor measures the vibration amplitude of the remanufacturing spray-coated workpiece, the cutting force measurement sensor measures the cutting force acting on the remanufacturing spray-coated workpiece, and the temperature measurement sensor measures the surface temperature of the remanufacturing spray-coated workpiece. The CNC machining equipment includes a memory, a processor, and a computer program stored in the memory and running on the processor. When the processor executes the program, it implements the remanufacturing spray-coated workpiece processing method described in this invention.

[0071] Vibration measurement sensors and cutting force measurement sensors can both be mounted on the workpiece fixture. Temperature measurement sensors can be non-contact sensors and can be installed at any suitable location where the temperature of the workpiece machining surface can be collected.

[0072] Specifically, in the roughing stage, the CNC machining equipment adjusts its machining parameters based on the constraint that the vibration amplitude of the remanufactured sprayed workpiece is less than a first preset threshold; in the semi-finishing stage, the CNC machining equipment adjusts its machining parameters based on the constraint that the cutting force on the remanufactured sprayed workpiece is less than a second preset threshold; and in the finishing stage, the CNC machining equipment adjusts its machining parameters based on the constraint that the surface temperature of the remanufactured sprayed workpiece is less than a third preset threshold.

[0073] It should be noted that if there is no machining allowance and semi-finishing can meet the surface quality requirements such as machining roughness, a finishing stage can be omitted. In this case, during the semi-finishing stage, in addition to adjusting the machining parameters of the processing equipment based on the constraint that the cutting force on the remanufactured sprayed workpiece is less than the second preset threshold, it is also necessary to adjust the machining parameters of the processing equipment based on the constraint that the surface temperature of the remanufactured sprayed workpiece is less than the third preset threshold.

Figure 3 As shown, the electronic device may include a processor 310, a communications interface 320, a memory 330, and a communication bus 340, wherein the processor 310, communications interface 320, and memory 330 communicate with each other via the communication bus 340.
