DETAILED DESCRIPTION OF THE DISCLOSURE

[0052] Aspects and embodiments of the present disclosure will now be discussed with reference to the accompanying figures. Further aspects and embodiments will be apparent to those skilled in the art.

[0053] FIG. 1 is a schematic diagram of a system 50 for controlling a treatment process that modifies surface properties of a component 10, according to an embodiment of the present disclosure. In some embodiments, the treatment process modifies mechanical properties of the component 10. In some embodiments, the component 10 is a part of a gas turbine engine (not shown). In some embodiments, the component 10 of the gas turbine engine is a bladed disk drum or a fan blade. The system 50 includes a treatment apparatus 100 for carrying out the treatment process.

[0054] FIG. 2 is a top perspective view of the treatment apparatus 100, according to an embodiment of the present disclosure. Some portions of the treatment apparatus 100 are shown as transparent in FIG. 2 for illustrative purposes. The treatment apparatus 100 is used to modify the mechanical and the surface properties of the component 10 in order to prolong its useful life and/or performance. In some embodiments, the treatment process for modifying the surface properties of the component 10 is vibropeening. Vibropeening is a process combining vibratory polishing and shot peening to a single polishing process in a vibratory bowl or a vibratory trough.

[0055] Referring to FIGS. 1 and 2, the treatment apparatus 100 includes a vibratory trough 102 for receiving and retaining treatment media 12. The vibratory trough 102 may take a variety of forms with respect to inter glia construction, shape, and materials. In the illustrated embodiment of FIG. 2, the vibratory trough 102 has a substantially u-shaped cross-section, The substantially u-shaped cross-section may enable a substantially uniform flow of the treatment media 12 in a desired direction when the vibratory trough 102 is in operation. For example, this may be useful when treating pressure and suction sides of aerofoils. The treatment media 12 may include steel media or shot, although ceramic, metallic, polymeric, composite, or any such material of appropriate hardness, size, or shape may be used depending on the component 10 and the treatment process.

[0056] In some embodiments, the vibratory trough 102 may be composed of a metal, e.g., aluminium or steel, and lined with a polyurethane layer (not shown) to protect the vibratory trough 102 and avoid any chemical reaction with the construction material of the vibratory trough 102. The polyurethane layer may ensure a smooth flow of the treatment media 12 within the vibratory trough 102. It may also be useful to apply a layer of polyurethane to metal parts of the treatment apparatus 100 for which any polishing is not required or is undesirable. Instead of polyurethane, other materials may be used to fulfil the same or similar purpose, e.g., the vibratory trough 102 may be lined with another polymeric material.

[0057] The treatment apparatus 100 further includes a component support 104 fixedly attached to the vibratory trough 102. In some embodiments, the component support 104 may be fixedly attached to the vibratory trough 102 via fasteners, such as screws, rivets, or nut and bolts. The component support 104 supports the component 10 within the vibratory trough 102. The component support 104 is located at least partially within the vibratory trough 102. The component 10 is removably attached to the component support 104. The component support 104 may take a variety of forms so as to support the component 10 to be treated in the treatment apparatus 100.

[0058] FIG. 3A is a perspective view of the treatment apparatus 100 with some components removed, according to an embodiment of the present disclosure. FIG. 3B is a top view of the treatment apparatus 100 with some components removed, according to an embodiment of the present disclosure. FIG. 3C is a side view of the treatment apparatus 100 with some components removed, according to an embodiment of the present disclosure. Referring to FIGS. 1 to 30, in some embodiments, the component support 104 includes a support fixture 110 and a support shaft 112 attached to the support fixture 110. In some embodiments, the support fixture 110 of the component support 104 is fixedly attached to the vibratory trough 102 by the fasteners. The support fixture 110 fixedly attaches the support shaft 112 to the vibratory trough 102 and the support shaft 112 removably mounts the component 10 within the vibratory trough 102. The support shaft 112 may be mounted using a bearing assembly 128 (shown in FIG. 3C). In some embodiments, the support shaft 112 may be a substantially hollow shaft that spans across each end of the vibratory trough 102.

[0059] In the illustrated embodiment of FIGS. 1 to 3C, the treatment apparatus 100 includes a pair of component supports 104 spaced apart from each other. The pair of component supports 104 includes respective support fixtures 110 opposing each other. The support shaft 112 extends at least between the support fixtures 110 of the pair of component supports 104.

[0060] In some embodiments, the treatment apparatus 100 further includes at least one trough wall 118 provided in the vibratory trough 102. The at least one trough wall 118 is configured to adjust a height, a volume, and/or a mass of the treatment media 12 in the vibratory trough 102. In the illustrated embodiment of FIG. 3A, the at least one trough 10 wall 118 includes a first trough wall 118a and an opposing second trough wall 118b provided in the vibratory trough 102. Each of the first and second trough walls 118a, 118b has an aperture (not shown) through which the support shaft 112 can pass. The first trough wall 118a is disposed proximal to one of the support fixtures 110, while the second trough wall 118b is disposed proximal to the other one of the support fixtures 110. During the treatment process, the support shaft 112 passes through the component 10. Further, during the treatment process, the first trough wall 118a and the second trough wall 118b are located on the support shaft 112 on either side of the component 10 in order to support the component 10 in a desired position within the vibratory trough 102. In this way, the support shaft 112 may be removably locatable within the vibratory trough 102 and shaped to support the component 10 in the treatment apparatus 100. In some cases, the component 10 includes a channel (not shown) through which the support shaft 112 may pass to support the component 10 within the vibratory trough 102 of the treatment apparatus 100. If the component 10 includes a pair of recesses rather than the channel, the support shaft 112 may include a pair of support shafts 112 and the component 10 may be supported within the vibratory trough 102 using the pair of support shafts rather than a single support shaft. The first trough wall 118a and the second trough wall 118b may be formed, shaped, angled and/or positioned in accordance with different application requirements.

[0061] The treatment apparatus 100 further includes at least one trough vibrating mechanism 106 (schematically shown in FIG. 1) that causes the vibratory trough 102 to vibrate.

[0062] The at least one trough vibrating mechanism 106 includes suitable equipment for the vibratory trough 102 to be rocked or otherwise oscillated, as desired. In some embodiments, the at least one trough vibrating mechanism 106 may include a plurality of actuators (not shown) and corresponding actuator extension rods (not shown). The actuator extension rods may be individually extendable, as required. The actuators may be powered pneumatically or hydraulically.

[0063] In some embodiments, the treatment apparatus 100 further includes a drive arrangement 120 configured to rotate the component 10 relative to the treatment media 12 (schematically shown in FIG. 1). The drive arrangement 120 includes a motor 124, a timing belt 126 (e.g., a chain drive), and a gearbox 122 with a variable gear ratio. Therefore, the support shaft 112 is rotated by the drive arrangement 120 during the treatment process. A speed of rotation of the support shaft 112 and the component 10 may be controlled by the gearbox 122 of the drive arrangement 120 in order to control the coverage and uniformity of the treatment process (i.e., vibropeening).

[0064] In some embodiments, the treatment apparatus 100 further includes a treatment media inlet 130 (shown in FIG. 30) for controllably supplying the treatment media 12 into the vibratory trough 102. In some embodiments, the treatment media inlet 130 may include an inlet valve (not shown) that is in fluid communication with a reservoir (not shown) storing the treatment media 12. In some embodiments, the treatment apparatus 100 further includes a treatment media outlet 132 (shown in FIG. 30) for controllably emptying the treatment media 12 from the vibratory trough 102. In some embodiments, the treatment media outlet 132 may include an outlet valve (not shown) to remove the treatment media 12 from the vibratory trough 102 after the treatment process is completed.

[0065] The system 50 further includes a plurality of sensor devices 14 respectively and fixedly disposed at a plurality of heights relative to the vibratory trough 102.

The plurality of movement parameters of the treatment media 12 may include an acceleration and/or a speed of the treatment media 12 at the plurality of heights. In some embodiments, the plurality of movement parameters may be a plurality of vibration parameters. Therefore, the plurality of movement signals 16 may be a plurality of vibration signals. In some embodiments, each of the plurality of sensor devices 14 is fixedly attached to the support fixture 110. Therefore, each of the plurality of sensor devices 14 may measure a relative movement parameter of the treatment media 12 with respect to the vibratory trough 102 at a corresponding height from the plurality of heights.

The central controller 18 is further configured to determine a measured process parameter 24 (shown in FIG. 1) based on the plurality of process variables 20. For example, the measured process parameter 24 may be an overall intensity of the treatment process which may be determined by the central controller 18 using the plurality of process variables 20 (e.g., a plurality of intensities) measured at the plurality of heights. In some embodiments, the central controller 18 is further configured to control the treatment apparatus 100 based on the predetermined process parameter 22 and the measured process parameter 24, such that a difference between the predetermined process parameter 22 and the measured process parameter 24 is reduced. By reducing the difference between the predetermined process parameter 22 and the measured process parameter 24, desirable intensity and/or energy (e.g., the predetermined process parameter 22) of the treatment process (i.e., vibropeening) may be obtained.

[0078] In some embodiments, the central controller 18 is further configured to, prior to receiving the plurality of movement signals 16 from the plurality of sensor devices 14, determine a plurality of predicted process variables 26 corresponding to the plurality of heights of the vibratory trough 102. The plurality of predicted process variables 26 may be predicted intensities of the treatment process (i.e., vibropeening) at the plurality of heights. In some embodiments, the plurality of predicted process variables 26 may be predicted based on one or more machine-learning models and/or algorithms.

[0079] In some embodiments, the central controller 18 is further configured to control the treatment apparatus 100 based on the plurality of predicted process variables 26 and the plurality of process variables 20, such that a difference between each of the plurality of process variables 20 and a corresponding predicted process variable 26 from the plurality of predicted process variables 26 is reduced. By reducing the difference between each of the plurality of process variables 20 and the corresponding predicted process variable 26 from the plurality of predicted process variables 26, desirable value of intensity and/or energy of the treatment process (i.e., vibropeening) may be obtained at the plurality of heights (i.e., H1, H2, H3, and so on, as shown in FIG. 1).

[0080] Referring again to FIGS. 1 to 4B, the central controller 18 controls the treatment apparatus 100 based at least on the plurality of process variables 20, such as a value of the energy, the coverage, and/or the intensity at the respective heights (i.e., H1, H2, H3, and so on) relative to the vibratory trough 102. The central controller 18 communicably coupled to the plurality of sensor devices 14 fixedly disposed at the plurality of heights relative to the vibratory trough 102 may enable the system 50 to monitor the plurality of movement signals 16 and the plurality of process variables 20 in specific sections of the vibratory trough 102. In other words, the system 50 may be used to obtain a desired parameter of the treatment process (i.e., vibropeening) for a specific aerospace component according to the drawing requirement.

[0081] As the controller 18 controls the treatment apparatus 100 based at least on the plurality of process variables 20 corresponding to the plurality of movement signals 16, the system 50 may provide uniform residual stress distribution and material properties across the component 10 during the treatment process (i.e., vibropeening), This may improve fatigue life and/or performance of the component 10. This is particularly important when the component 10 is large in size. Further, unlike conventional techniques where a component (subject part) may have to be scrapped if there is any error in obtaining the drawing requirement (e.g., Almen intensity), the system 50 may enable monitoring the vibropeening at specific heights and accordingly controlling the vibropeening of the component 10. As a result, a likelihood of scrapping the component 10 after the treatment process of the component 10 may be reduced by the system 50 of the present disclosure. Therefore, the central controller 18 and the plurality of sensor devices 14 may validate a process control method and/or mechanism for the treatment process for the component 10.

[0082] Moreover, as compared to the conventional vibropeening techniques, the system 50 may substantially reduce human intervention because of continuous determination of the plurality of process variables 20 corresponding to the plurality of movement signals 16 and subsequently controlling the treatment apparatus 100 based at least on the plurality of process variables 20. The system 50 may enable the vibropeening which is relatively faster with less intensive manual labour. Further, in the system 50, there are minimal chances of wastage of sacrificial Almen strips or scrapping of components which may not meet the drawing requirements. The system 50 may be used for vibropeening of rotationally symmetric as well as asymmetric components.

[0083] FIG. 5A is a perspective view of a system 50 for controlling the treatment process that modifies surface properties of the component 10, according to an embodiment of the present disclosure. The system 50 is substantially similar and functionally equivalent to the system 50 of FIG. 1, with common components being referred to by the same numerals. Some portions of the treatment apparatus 100 are shown as transparent in FIG. 5A for illustrative purposes. Some of the components are not shown in FIG. 5A for illustrative purposes. However, in the illustrated embodiment of FIG. 5A, the system 50 further includes a frame 114 fixedly attached to the vibratory trough 102.

[0084] FIG. 5B is a perspective view of the frame 114, according to an embodiment of the present disclosure. Functional advantages of the system 50 is the same as that of the system 50 of FIG. 1.

[0085] Referring to FIGS. 5A and 5B, the frame 114 includes one or more vertical hangers 116. Each of the one or more vertical hangers 116 extends at least partially into the treatment media 12. In the illustrated embodiment of FIGS. 5A and 5B, a total of four vertical hangers 116 are shown. However, in other embodiments, the frame 114 may include any number of the vertical hangers 116. Each of the plurality of sensor devices 14 is fixedly attached to the one or more vertical hangers 116 of the frame 114. In the illustrated embodiment of FIGS. 5A and 5B, a total of three sensor devices 14 are fixedly attached to each vertical hanger 116. In other embodiments, any number of sensor devices 14 may be fixedly attached to each vertical hanger 116, as per application requirements.

[0086] FIG. 6 is a flowchart illustrating a method 200 for controlling the treatment process that modifies the surface properties of the component 10 (shown in FIGS. 1 and 2), according to an embodiment of the present disclosure.

[0087] Referring to FIGS. 1 to 6, at step 202, the method 200 includes providing the treatment apparatus 100 (shown in FIGS. 1 and 2) for carrying out the treatment process. At step 204, the method 200 includes providing the plurality of sensor devices 14 (shown in FIGS. 1 and 2) respectively and fixedly disposed at the plurality of heights (i.e., H1, H2, H3, and so on, shown in FIG. 1) relative to the vibratory trough 102.

[0088] At step 206, the method 200 includes receiving the plurality of movement signals 16 (shown in FIG. 1) from the plurality of sensor devices 14. At step 208, the method 200 includes determining the plurality of process variables 20 (shown in FIG. 1) corresponding to the plurality of movement signals 16. At step 210, the method 200 includes controlling the treatment apparatus 100 based at least on the plurality of process variables 20. In some embodiments, the central controller 18 may include a memory (not shown) storing computer executable instructions or computer code that may be executed by the central controller 18 to perform the step 210 of the method 200.

[0089] In some embodiments, controlling the treatment apparatus 100 further includes controlling the at least one trough vibrating mechanism 106 based on the plurality of process variables 20. For example, the central controller 18 may control one or more of the plurality of actuators and the corresponding actuator extension rods of the treatment apparatus 100 based at least on the plurality of process variables 20 to adjust the amount of vibration of the vibratory trough 102. In some embodiments, controlling the treatment apparatus 100 further includes adjusting the height, volume, and/or mass of the treatment media 12 in the vibratory trough 102 based on the plurality of process variables 20. For example, the central controller 18 may control the first trough wall 118a and/or the second trough wall 118b of the treatment apparatus 100 based at least on the plurality of process variables 20 to adjust the height, volume, and/or mass of the treatment media 12 in the vibratory trough 102. In some embodiments, controlling the treatment apparatus 100 further includes controlling a rotation of the component 10 relative to the treatment media 12 based on the plurality of process variables 20. For example, the central controller 18 may adjust a speed of rotation of the support shaft 112 and thereby, the rotation of the component 10 by controlling the gearbox 122 of the drive arrangement 120. In some embodiments, controlling the treatment apparatus 100 further includes controllably supplying the treatment media 12 into the vibratory trough 102 and/or controllably emptying of the treatment media 12 from the vibratory trough 102 based on the plurality of process variables 20. For example, the central controller 18 may control the treatment media inlet 130 and/or the treatment media outlet 132 of the treatment apparatus 100 based at least on the plurality of process variables 20 to adjust the height, volume, and/or mass of the treatment media 12 in the vibratory trough 102.

[0090] In some embodiments, the method 200 further includes receiving the predetermined process parameter 22 (shown in FIG. 1) of the treatment process. The method 200 further includes determining the measured process parameter 24 (shown in FIG. 1) based on the plurality of process variables 20. In some embodiments, controlling the treatment apparatus 100 further includes controlling the treatment apparatus 100 based on the predetermined process parameter 22 and the measured process parameter 24, such that the difference between the predetermined process parameter 22 and the measured process parameter 24 is reduced.

[0091] In some embodiments, the method 200 further includes, prior to receiving the plurality of movement signals 16 from the plurality of sensor devices 14, determining the plurality of predicted process variables 26 (shown in FIG. 1) corresponding to the plurality of heights of the vibratory trough 102. In some embodiments, controlling the treatment apparatus 100 further includes controlling the treatment apparatus 100 based on the plurality of predicted process variables 26 and the plurality of process variables 20, such that the difference between each of the plurality of process variables 20 and the corresponding predicted process variable 26 from the plurality of predicted process variables 26 is reduced.
