Description
BACKGROUND INFORMATION

1. Field


The present disclosure relates generally to cutting materials and in particular to a method and apparatus for cutting slots in materials. Still more particularly, the present disclosure relates to a method and apparatus for creating slots to separate parts.


2. Background


During manufacturing and/or maintenance, it may be necessary to remove parts from an aircraft. For example, without limitation, during assembly of an aircraft wing, it may be necessary to remove a spar or some other part for any number of reasons. During maintenance or other post-assembly operations, it may be desirable to replace parts.


For example, without limitation, a spar may be removed from the interior of an aircraft wing, and a new spar may be put in its place. When a spar is already present within an aircraft wing, a spar may not be easily removable without cutting the spar into multiple pieces. This situation may arise because of a lack of space within an assembled aircraft wing.


When removing a spar from an aircraft wing, it may be necessary to cut through the spar down to near the skin panel to which the spar may be attached. The skin panel may be a metallic, composite and metallic or composite skin panel. As a result, it may be important to not touch and/or cut into the skin panel, while cutting the spar into multiple pieces. It may be undesirable for a cutting tool to touch and/or cut into a skin panel. Touching or trimming the skin panel may extend the rework beyond the original scope of the project.


Currently, cuts may be made into the spar by hand. An operator may employ a cutting tool by hand to cut through the spar. The operator may make successive cuts deeper into the spar in an attempt to create a cut that may be deep enough to allow for separation of the spar into multiple pieces without touching and/or cutting into the skin panel. Large portions of the spar may be cut away leaving smaller portions that may be attached to the skin panel. These portions may be removed in pieces. The cuts made into the portions of the spar that may be attached to the skin panel may take the form of slots. These slots may be cut within 1/1,000 at 1/100 of an inch to the surface of the skin panels without touching the skin panels.


This type of operation may be very time consuming. Further, expenses may increase if cuts touch and/or extend into the skin panel.


Accordingly, a need is present for a method and apparatus to minimize the time and effort needed to remove parts that overcome the problems discussed above.

Of course, other depths may be left in section 516 depending on the particular implementation. For example and without limitation, a depth of around 0.1 inches, around 0.001 inches, or some other suitable depth may be selected for section 516. The depth may depend on the number of steps present within cut stop 434.


Thereafter, cut stop 434 may be adjusted to a highest setting in preparation for an initial cut. Cutting unit 412 may be locked into place using depth set unit 440.


Cutting unit 412 may then be activated by activating the air supply to air supply unit 416.


Carriage 410 may be moved along roller bearing track 406 and roller bearing track 408 in the direction of axis 518 to cut slot 514 into spar 500. When a cut is made into slot 514, carriage 410 may be moved back to starting point 505. Cut stop 434 may be adjusted to lower end mill cutter 418 to a next level. Then, another cut may be made into spar 500 to increase the depth of slot 514. This process may be repeated until section 516 is reached. Section 516 may be reached without touching and/or cutting into surface 508 of skin panel 502.


The dimensions of cutting tool system 400 may vary depending on the particular implementation. In these examples, cutting tool system 400 may have a size that makes this system portable and useable within a wing of an aircraft to cut slots into structures such as, for example, without limitation, spar 500. Cutting tool system may have length 519 of around 21.0 inches, height 520 of around 13.0 inches, and width 522 of around 5.0 inches. Of course, the dimensions may vary depending on the particular implementation selected. Further, cutting tool system 300 also may provide a size advantage based on its design and/or configuration in these examples.


The illustration of cutting tool system 400 in FIGS. 4 and 5 has been presented as one implementation of cutting tool system 300 in FIG. 3. This illustration is not meant to imply physical and/or architectural limitations to the manner in which other advantageous embodiments may be implemented.


For example, without limitation, in other advantageous embodiments, a different tool other than end mill cutter 418 may be used. For example, without limitation, a bit and/or tool in the form of a dove tail cutter, a slotting cutter, a contour cutter, or some other suitable tool may be used. As another non-limiting example, three tracks may be used instead of roller bearing track 406 and roller bearing track 408.


With reference now to FIG. 6, a perspective view of a workpiece and a part is depicted in accordance with an advantageous embodiment. In this example, spar 500 is shown with access slot 504 and slot 514 after cutting operations have been completed using cutting tool system 400.


With reference now to FIG. 7, a high level flowchart of a process for cutting a slot in a part is depicted in accordance with an advantageous embodiment. The process illustrated in FIG. 7 is an example of a process that may be implemented using cutting tool system 300 in FIG. 3.


The process may begin by placing cutting tool system 300 on surface 324 of a material (operation 700). The final depth of a cutter may be set (operation 702). The process may select a depth of a pass using depth controller 310 in the cutting tool system (operation 704). In operation 704, the pass may be one of a number of passes used to form the slot. Each pass may make a deeper cut into the part to form the slot. Thereafter, the process may cut the slot using the cutting tool system (operation 706). A determination may be made as to whether the final depth has been reached (operation 708). If the final depth has been reached, the process may terminate. Otherwise, the process may return to operation 704 to select a new depth for a pass.


With reference now to FIG. 8, a flowchart of a process for cutting a slot in a workpiece attached to a skin panel is depicted in accordance with an advantageous embodiment. The process illustrated in FIG. 8 may be implemented using a cutting tool system, such as cutting tool system 300 in FIG. 3.


The process may begin by cutting access slot 504 in workpiece 326 (operation 800). This access slot may be cut having a width to allow placement of cutting tool system 400 onto surface 506 of workpiece 326 where slot 514 may be desired. This operation may be performed by an operator using an existing access hole or port in the aircraft. This operation may be performed using cutting tool system 400, or some other suitable tool. Cutting tool system 400 may be placed into the access slot (operation 802). Carriage 410 may be positioned at starting point 505 (operation 804).


Next, clamp bar 432 may be positioned touching a top surface of a portion of workpiece 326 (operation 806). The process may then lock clamp bar 432 in place (operation 808). This operation may secure the cutting tool system to part 344. A foot system, such as adjustable feet 312, may be positioned to touch the surface of skin panel 502 (operation 810). Feet 444 and 446 may be clamped to the surface (operation 811). In operation 811, clamp bar thrust screw 428 may be tightened to clamp the feet to the surface of skin panel 502.


Cut stop 434 may be rotated to a lowest position to set a depth of slot 514 (operation 812). In the illustrative examples, the lowest position may identify the amount of material left in the part when slot 514 is complete. The process may move cut stop 434 to the high setting for the first cut (operation 814). The process may then lock cutting unit 412 in place in the carriage (operation 816).


The air supply, such as, for example, without limitation, air motor 414, may be attached to air supply inlet 416 (operation 818). The air supply may be activated using foot pedal 450 (operation 820). Carriage 412 may be moved along track system 404 to cut slot 514 (operation 822). The process then may return to the starting point (operation 824).


A determination may be made as to whether slot 514 is complete (operation 826). If slot 514 is not complete, cut stop 434 may be adjusted to a next lower position (operation 828). The process may lock cutting unit 412 in place (operation 830). The process may activate the air supply provided by air motor 414 (operation 832). The process may then move carriage 410 to further cut slot 514 (operation 834), with the process returning to operation 824. In these examples, each cut may increase the depth of slot 514. With reference back to operation 826, if slot 514 has been completed, the process terminates.


Thus, the different advantageous embodiments may provide a method and apparatus for cutting slot 344 in workpiece 344. In the different advantageous embodiments, an apparatus may have frame 302, track system 304, carriage 306, cutting unit 308, and depth controller 310.
