[0021] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] A remanufactured spray-coated workpiece is a new workpiece obtained after a coating treatment is performed on the surface of the workpiece, which improves the performance of the workpiece or repairs and remanufactures the workpiece. The coating thickness of a remanufactured spray-coated workpiece is often relatively thin, about 1 mm. When processing the coating, due to its thin thickness and limited bonding strength between the coating and the workpiece surface, its processing technology is different from that of a workpiece made of uniform material. The embodiment of the present invention, that is, when processing a remanufactured spray-coated workpiece, considers the limitations of the coating thickness and bonding strength between the coating and the workpiece surface of the remanufactured spray-coated workpiece, and proposes a processing technology suitable for remanufactured spray-coated workpieces, that is, at different processing stages, different processing parameter adjustment strategies are given according to the unique properties of the remanufactured spray-coated workpiece (thin coating thickness, limited bonding strength between the coating and the workpiece surface), so as to achieve adaptive processing of the remanufactured spray-coated workpiece, thereby obtaining a high-quality remanufactured spray-coated workpiece.

[0023] The following combination Figure 1-Figure 2 The method for processing a remanufactured sprayed workpiece of the present invention is described. Figure 1 One of the flow charts of the method for remanufacturing a spray-coated workpiece provided by an embodiment of the present invention is exemplarily shown. Figure 1 As shown, the method includes the following steps 101 to 102.

[0024] Step 101 : During a rough machining phase, machining parameters of a machining device are adjusted based on a constraint that the vibration amplitude of the remanufactured sprayed workpiece is less than a first preset threshold.

[0025] The coating of a remanufactured spray-coated workpiece is formed by mixing powders of various materials and then adhering to the surface of the workpiece via thermal spraying. In addition to the uneven physical structure of the coating surface causing processing vibration, the uneven distribution of hard particles in the coating material also causes processing vibration. This means that during the rough machining stage, the vibration amplitude of the remanufactured spray-coated workpiece will be relatively large. However, for remanufactured spray-coated workpieces, due to their thin coating thickness, severe vibrations will affect their machining accuracy and may even ultimately result in the size and shape failing to meet machining requirements. To ensure the normal machining of the remanufactured spray-coated workpiece, an embodiment of the present invention monitors the vibration amplitude of the remanufactured spray-coated workpiece in real time during the rough machining stage, controlling the vibration of the remanufactured spray-coated workpiece within a certain range to avoid the impact of vibration on machining accuracy.

[0026] It should be noted that the above-mentioned processing usually refers to processing using turning, milling, lathe, milling machine and other processing methods.

[0027] Step 102 : During the semi-finishing stage, the machining parameters of the machining equipment are adjusted based on the constraint that the cutting force on the remanufactured spray-coated workpiece is less than a second preset threshold.

[0028] This embodiment takes into account the problem that the thickness of the coating is not large and the bonding strength between the coating and the workpiece surface is limited. In the semi-finishing stage, the distance between the machining surface and the bonding layer between the coating and the workpiece surface is closer than that between the machining surface and the bonding layer between the coating and the workpiece surface in the rough machining stage. The magnitude of the cutting force on the machining surface has a great influence on the bonding between the coating and the workpiece surface. That is, in the semi-finishing stage, if the cutting force is too large, the risk of the bonding surface between the coating and the workpiece surface being damaged increases, and in severe cases, the coating may fall off the workpiece surface. Based on this, this embodiment needs to ensure that the cutting force on the remanufactured sprayed workpiece can be borne by the bonding strength between the coating and the workpiece surface in the semi-finishing stage. Therefore, in the semi-finishing stage, the cutting force on the workpiece machining surface is controlled within a certain range (i.e., less than the second preset threshold).

[0029] It's important to note that after removing any surface unevenness in the coating during roughing, the material distribution within the coating becomes compact and uniform, and the resulting machining vibration is no longer a major factor affecting machining. Therefore, during semi-finishing, the primary machining parameter adjustment strategy is to keep the cutting force on the workpiece surface within a certain range (i.e., below the second preset threshold).

[0030] In an example embodiment, Figure 2 The second flow chart of the method for remanufacturing a spray-coated workpiece according to an embodiment of the present invention is shown as an example. Figure 2 As shown, based on the above embodiment, the method further includes: Step 103, in the finishing stage, adjusting the processing parameters of the processing equipment based on the constraint that the temperature of the surface of the remanufactured sprayed workpiece is less than a third preset threshold.

[0031] It should be noted that during the finishing stage, high cutting speeds are used, which generates significant heat during machining, exacerbating residual stresses in the material and leading to increased surface thermal modification. To avoid the generation of residual stresses and changes in workpiece surface properties, this embodiment primarily controls the temperature parameter of the machined surface during the finishing stage, maintaining it within a certain range (i.e., less than a third preset threshold) to prevent excessive temperatures from altering the properties of the workpiece surface.

[0032] In one exemplary embodiment, if there is no allowance for finishing due to machining allowance limitations and semi-finishing can meet surface quality requirements such as machining roughness, semi-finishing can be directly used as the final machining stage, i.e., no finishing stage is required. In this case, during the semi-finishing stage, in addition to adjusting the machining parameters of the machining equipment based on the constraint that the cutting force on the remanufactured spray-coated workpiece is less than a second preset threshold, the machining parameters of the machining equipment also need to be adjusted based on the constraint that the surface temperature of the remanufactured spray-coated workpiece is less than a third preset threshold. In other words, during 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, while also preventing excessive temperatures from causing changes in the properties of the workpiece's machined surface.

[0033] It should be noted that the processing parameters involved in all the above embodiments include cutting speed and cutting depth. The vibration amplitude, cutting force and temperature are all collected and obtained by corresponding measurement sensors. Among them, the temperature measurement sensor can be a non-contact sensor, and the temperature measurement sensor can be installed in any suitable position so as to collect the temperature of the workpiece processing surface. The vibration measurement sensor and the cutting force measurement sensor can be installed on the fixture of the workpiece. Of course, they can also be installed in other positions, as long as the corresponding vibration amplitude or cutting force can be measured. The present invention does not limit this.

[0034] In an example embodiment, in the above step 101, the processing parameters of the processing equipment are adjusted based on the constraint that the vibration amplitude of the remanufactured sprayed workpiece is less than a first preset threshold value. Specifically, the following steps may be included: obtaining the vibration amplitude data of the remanufactured sprayed workpiece, and judging whether the vibration amplitude data is less than the first preset threshold value; if the vibration amplitude is not less than the first preset threshold value, adjusting the processing parameters, re-obtaining the vibration amplitude data of the remanufactured sprayed workpiece after the processing parameters are adjusted, and judging whether the vibration amplitude data is less than the first preset threshold value, and stopping the adjustment of the processing parameters until the vibration amplitude data is less than the first preset threshold value.

[0035] Similarly, in an example embodiment, in the above step 102, the processing parameters of the processing equipment are adjusted based on the constraint that the cutting force exerted on the remanufactured sprayed workpiece is less than a second preset threshold value. Specifically, the following steps may be included: obtaining the cutting force data exerted on the remanufactured sprayed workpiece, and judging whether the cutting force data is less than the second preset threshold value; if the cutting force is not less than the second preset threshold value, adjusting the processing parameters, re-obtaining the cutting force data exerted on the remanufactured sprayed workpiece after the processing parameters are adjusted, and judging whether the cutting force data is less than the second preset threshold value, and stopping the adjustment of the processing parameters until the vibration amplitude data is less than the second preset threshold value.

[0036] In an example embodiment, in the above-mentioned step 103, the processing parameters of the processing equipment are adjusted based on the constraint that the temperature of the surface of the remanufactured sprayed workpiece is less than a third preset threshold value. Specifically, the following steps may be included: obtaining the temperature of the surface of the remanufactured sprayed workpiece, and judging whether the temperature is within the third preset threshold value; if the temperature is not within the third preset threshold value, adjusting the processing parameters, re-obtaining the surface temperature data of the remanufactured sprayed workpiece after the processing parameters are adjusted, and judging whether the surface temperature data is less than the third preset threshold value, and stopping the adjustment of the processing parameters until the surface temperature data is less than the third preset threshold value.

[0037] It should be noted that the above-mentioned control process of the processing parameters is a feedback adjustment process, that is, the processing 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 processing parameters are adjusted. After the processing 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 processing parameters are continued to be adjusted until the collected vibration amplitude, cutting force or temperature is less than the corresponding preset value, and the adjustment of the processing parameters is stopped.

[0038] The first preset threshold, the second preset threshold, and the third preset threshold in the embodiment of the present invention are all based on actual processing requirements and determined according to actual processing experience.

[0039] The following takes the adjustment of machining parameter feedback based on cutting force as an example to introduce the adjustment details of the machining parameters in the above embodiment.

[0040] During processing, the cutting force value of the remanufactured spray workpiece is collected in real time, and it is determined whether the cutting force value is less than a second preset threshold value. If the cutting force value is less than the second preset threshold value, processing is continued with the current processing parameters. If the cutting force value is greater than or equal to the second preset threshold value, the cutting speed and cutting depth are adjusted, such as reducing the cutting speed or reducing the cutting depth.

[0041] In one exemplary embodiment, also using cutting force as an example, the system may store a corresponding adjustment relationship curve or relationship table between machining parameters and cutting force values. Specifically, the adjustment magnitude of the machining parameters may be determined based on the difference between the actual measured cutting force value and a second preset threshold. For example, if the actual measured cutting force value is 1.5 times the second preset threshold, the machining parameters may be reduced by 1.5 times. Of course, this example shows a linear adjustment, but a corresponding adjustment based on a curve relationship may also be made according to actual circumstances.

[0042] In one exemplary embodiment, a fixed adjustment amount may also be set. Again, using cutting force as an example, when the actual measured value of the cutting force is greater than a second preset threshold, the processing parameter (cutting depth or cutting speed) is reduced by a fixed amount, and the cutting force is then measured again. If the actual measured value of the cutting force is still greater than the second preset threshold, the processing parameter is further reduced by the fixed amount until the actual measured value of the cutting force is less than the second preset threshold. Of course, the fixed adjustment amount may 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) may be set. When the actual measured value of the cutting force is within the interval (200N, 220N), the processing parameter is reduced by the first fixed adjustment amount. When the actual measured value of the cutting force is within the interval (200N, 240N), the processing parameter is reduced by the second fixed adjustment amount. It is 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 interval (240 N, 260 N), the third fixed adjustment amount is used to reduce the machining parameter, and the third fixed adjustment amount is greater than the second fixed adjustment amount.

[0043] It should be noted that when adjusting machining parameters, one can adjust only the cutting depth, only the cutting speed, or both. For example, if the actual measured cutting force is 1.5 times the second preset threshold, then the cutting speed can be reduced by 1.5 times, the cutting depth can be reduced by 1.5 times, or the cutting speed and cutting depth can be reduced by 0.75 times each.

[0044] In an example embodiment, also taking the cutting force as an example, after adjusting the cutting force to less than the second preset threshold by adjusting the processing parameters using the method described in the previous embodiment, in order to take into account other factors such as efficiency and avoid excessively reducing the cutting depth or cutting speed, the cutting depth or cutting speed can also be slightly increased to ensure that the processing efficiency is appropriately improved under the premise that the cutting force is not greater than 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 the current cutting force is less than the second preset threshold. If it is less than the second preset threshold, keep the current processing parameters unchanged, or further slightly increase the cutting depth or cutting speed, collect the current cutting force again and analyze whether the current cutting force is less than the second preset threshold. If the current cutting force is greater than the second preset value, use the processing parameters before the most recent slight increase in cutting depth or cutting speed for processing.

[0045] In this embodiment, the number of small adjustments can be one or more times. The specific amplitude or specific change value involved in the small adjustment can be set according to experience and actual conditions, and the present invention does not impose any limitation on this.

[0046] It should be noted that the method for adjusting the machining parameters in the rough machining stage can refer to the method for adjusting the machining parameters in the semi-finishing stage, that is, the detailed method for adjusting the machining parameters based on the vibration amplitude can refer to the detailed method for adjusting the machining parameters based on the cutting force. However, the method for adjusting the machining parameters in the finishing stage cannot completely refer to the method for adjusting the machining parameters in the semi-finishing stage, that is, the detailed method for adjusting the machining parameters based on the resulting surface temperature cannot completely refer to the detailed method for adjusting the machining parameters based on the cutting force. The main reason is that the finishing stage has requirements for machining accuracy and surface quality. Therefore, when adjusting the machining parameters based on the machining surface temperature, the impact of the change in machining parameters on machining accuracy and machining quality must also be weighed. The adjustment of the machining parameters requires that the temperature of the machining surface be controlled below the third preset threshold value, and that the machining accuracy and surface quality of the workpiece meet the set requirements.

[0047] Specifically, the detailed method for adjusting machining parameters based on cutting force can be referenced to adjust machining parameters based on the machining surface temperature. It is necessary to predetermine the range of machining parameters that can guarantee machining accuracy and surface quality. Before adjusting machining parameters based on the machining 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 must be re-determined. Of course, other methods can also be used to achieve a balance between surface temperature, machining accuracy, and surface quality, and the present invention does not limit this.

[0048] In an exemplary embodiment, taking a remanufactured spray-coated workpiece having a thickness of about 1 mm as an example, the entire machining process may include one roughing process, one semi-finishing process, and one finishing process; or the entire machining process may only include one roughing process and one semi-finishing process.

[0049] The embodiments of the present invention are described in detail below with reference to specific examples.

[0050] CNC systems use G-code to rapidly process workpieces. G-code generation relies on the configuration and command transmission of a CNC machining control algorithm. This algorithm features adaptive adjustment capabilities, enabling efficient CNC machining based on feedback from vibration, cutting force, and temperature sensors during machining. This algorithm is the same algorithm described in the previous examples that adjusts machining parameters based on vibration amplitude, cutting force, and temperature.

[0051] The thickness of the spray coating on the remanufactured sprayed workpiece is only about 1mm. In order to achieve fast and high-quality processing, the ideal way is to optimize the processing steps, mainly including roughing, semi-finishing and finishing.

[0052] (1) The first rough machining is mainly aimed at eliminating the unevenness of the workpiece surface (cutting depth 0.2mm~0.3mm). It is usually carried out by turning, milling, lathe, milling machine and other processing methods. The main manifestation is the influence of vibration. The non-uniform characteristics of the workpiece surface are monitored by vibration measurement sensors, and the analysis results are fed back to the control algorithm, so that the control algorithm can make corresponding adaptive adjustments.

[0053] (2) The second semi-finishing process 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. The cutting force sensor is used to monitor this and the results are fed back to the control algorithm, which makes corresponding adjustments.

[0054] (3) The cutting depth of the third finishing operation is (0.05mm~0.1mm). This is the final processing. High cutting speed is used during the processing, which generates significant heat, exacerbating the generation of residual stress in the material and causing more surface thermal modification problems. To address these issues, industrial ultra-high-definition lenses and infrared temperature sensors are used to monitor the processing process. The signals are fed back to the control algorithm, allowing adaptive adjustments to meet the processing requirements.

[0055] During the entire machining process, the CNC machining control algorithm can make corresponding CNC machining process adjustments based on the specific conditions of each machining step, so that the workpiece can achieve the effect of CNC rapid machining and realize the expected technical indicators.

[0056] The method for remanufacturing spray-coated workpieces provided by embodiments of the present invention is an intelligent processing flow. During the machining process, key process factors are monitored and analyzed, and the results are fed back to a control algorithm in real time. The control algorithm adaptively adjusts the machining parameters of the CNC machine tool, achieving intelligent and rapid machining of the remanufactured workpiece. The engineering implementation of this invention will effectively reduce the number of remanufacturing steps and improve efficiency. The adaptive control of key machining signal feedback can further ensure high-quality completion of the machining process.

[0057] An embodiment of the present invention also provides a system for processing a remanufactured spray-coated workpiece. The system comprises: a numerically controlled (CNC) machining device, a vibration measurement sensor, a cutting force measurement sensor, and a temperature measurement sensor. The vibration measurement sensor measures the vibration amplitude of the remanufactured spray-coated workpiece, the cutting force measurement sensor measures the cutting force applied to the remanufactured spray-coated workpiece, and the temperature measurement sensor measures the surface temperature of the remanufactured spray-coated workpiece. The CNC machining device comprises a memory, a processor, and a computer program stored in the memory and executed on the processor. When the processor executes the program, it implements the method for processing a remanufactured spray-coated workpiece described in an embodiment of the present invention.

[0058] The vibration measurement sensor and the cutting force measurement sensor can both be installed on the workpiece fixture, and the temperature measurement sensor can be a non-contact sensor and can be installed at any suitable position where the temperature of the workpiece processing surface can be collected.

[0059] Specifically, in the rough machining stage, the CNC machining equipment adjusts the machining parameters of the machining equipment based on the vibration amplitude of the remanufactured sprayed workpiece being less than a first preset threshold value; in the semi-finishing stage, the CNC machining equipment adjusts the machining parameters of the machining equipment based on the cutting force exerted on the remanufactured sprayed workpiece being less than a second preset threshold value; in the finishing stage, the CNC machining equipment adjusts the machining parameters of the machining equipment based on the temperature of the surface of the remanufactured sprayed workpiece being less than a third preset threshold value.

[0060] It should be noted that if there is no allowance for finishing due to machining allowance constraints, and semi-finishing can meet the surface quality requirements such as machining roughness, the finishing stage can be omitted. In this case, during the semi-finishing stage, in addition to adjusting the machining equipment parameters based on the cutting force on the remanufactured sprayed workpiece being less than the second preset threshold, the machining equipment parameters also need to be adjusted based on the surface temperature of the remanufactured sprayed workpiece being less than the third preset threshold.

[0061] Figure 3 An example of a physical structure diagram of an electronic device is shown below. Figure 3 As shown, the electronic device may include: a processor 310, a communications interface 320, a memory 330, and a communications bus 340. The processor 310, the communications interface 320, and the memory 330 communicate with each other via the communications bus 340. The processor 310 may invoke logic instructions stored in the memory 330 to execute a method for processing a remanufactured spray-coated workpiece. The method includes: during a rough machining phase, adjusting machining parameters of a machining device based on the vibration amplitude of the remanufactured spray-coated workpiece being less than a first preset threshold; and during a semi-finishing phase, adjusting machining parameters of the machining device based on the cutting force applied to the remanufactured spray-coated workpiece being less than a second preset threshold. In one exemplary embodiment, the method further includes: during a finishing phase, adjusting machining parameters of the machining device based on the surface temperature of the remanufactured spray-coated workpiece being less than a third preset threshold. For more specific methods, reference may be made to the method for processing a remanufactured spray-coated workpiece described above and will not be repeated here.

[0062] Furthermore, the logic instructions in the aforementioned memory 330 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium.

In an exemplary embodiment, the remanufactured spray workpiece processing method also includes: in the finishing stage, the temperature of the surface of the remanufactured spray workpiece is less than a third preset threshold value as a constraint to adjust the processing parameters of the processing equipment.
