Patent Description:
For example, when assembling the fuselage and wings of an aircraft, a shim is inserted into a gap between a plurality of assembly components and the gap is filled with the shim. Japanese Unexamined Patent Application Publication <CIT> discloses a method of manufacturing a shim by measuring the thickness of a gap between a plurality of assembly components and three-dimensionally machining a workpiece by a processing machine on the basis of the distribution of the measured gap thickness. <CIT> discloses a method of manufacturing junction parts for an aircraft wing. In this method, every junction part is manufactured with overmaterial, which is subject to be post-processed, once as built measurements are performed and new trajectories are generated.

The present invention is defined by independent claim <NUM> as appended. Further embodiments are given in dependent claims.

The accompanying drawings are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments and, together with the specification, serve to explain the principles of the invention.

In <CIT>, a step of measuring a gap between a plurality of assembly components, a step of manufacturing a shim, and a step of inserting the shim are performed. Therefore, an assembly operation of assembling the assembly components may be complicated.

It is desirable to provide an assembling device that makes it possible to facilitate an assembly operation of assembling assembly components.

In the following, an embodiment of the invention is described in detail with reference to the accompanying drawings.

Further, elements in the following embodiment which are not recited in a most-generic independent claim of the invention are optional and may be provided on an as-needed basis. The drawings are schematic and are not intended to be drawn to scale. Throughout the present specification and the drawings, elements having substantially the same function and configuration are denoted with the same numerals to avoid any redundant description.

<FIG> is a schematic perspective view of an aircraft <NUM>. As illustrated in <FIG>, the aircraft <NUM> includes a fuselage <NUM>, main wings <NUM>, horizontal tails <NUM>, and a vertical tail <NUM>. The main wings <NUM>, the horizontal tails <NUM>, and the vertical tail <NUM> may also be simply referred to as "wings" below.

The fuselage <NUM> extends in a roll axis direction that joins the nose side and the tail side of the aircraft <NUM> with each other. Each main wing <NUM> is provided on a central portion of the fuselage <NUM> in the roll axis direction.

The main wings <NUM> are provided in a pair, one on the left side and one on the right side of the fuselage <NUM> in a pitch axis direction orthogonal to the roll axis direction. The main wings <NUM> extend outward from the fuselage <NUM> in the pitch axis direction. Each main wing <NUM> has the function of generating a vertically upward lift at the aircraft <NUM>.

The horizontal tails <NUM> are provided on the fuselage <NUM> rearward of (on the tail side with respect to) the main wings <NUM>. The horizontal tails <NUM> are provided in a pair, one on the left side and the other on the right side of the fuselage <NUM> in the pitch axis direction. The horizontal tails <NUM> extend outward from the fuselage <NUM> in the pitch axis direction. Each horizontal tail <NUM> has the function of maintaining the stability of the aircraft <NUM> around the pitch axis.

The vertical tail <NUM> is provided on the fuselage <NUM> rearward of (on the tail side with respect to) the main wings <NUM>. The vertical tail <NUM> extends outward from the fuselage <NUM> in a yaw axis direction orthogonal to the roll axis direction and the pitch axis direction. The vertical tail <NUM> has the function of maintaining the stability of the aircraft <NUM> around the yaw axis.

<FIG> is a schematic sectional view along line II-II of a main wing <NUM> illustrated in <FIG>. As illustrated in <FIG>, the main wing <NUM> includes a skin <NUM>, stringers <NUM>, and a rib <NUM>. In one embodiment, the skin <NUM> may serve as a "panel", the stringers <NUM> may serve as "first assembly components", and the rib <NUM> may serve as a "second assembly component".

The skin <NUM> is constituted by a plate member and is formed into a streamline-shaped wing. An outer surface of the skin <NUM> is exposed to an external space S1, and an accommodation space S2 is formed on an inner side of the skin <NUM>. Each stringer <NUM> has an I shape and is accommodated in the accommodation space S2.

One end of each stringer <NUM> is coupled to the skin <NUM> and the other end of each stringer <NUM> is coupled to the rib <NUM>. In the present embodiment, each stringer <NUM> is integrated with the skin <NUM>. However, each stringer <NUM> may be formed separately from the skin <NUM> and affixed to the skin <NUM>.

The rib <NUM> has a hollow rectangular shape and is accommodated in the accommodation space S2. The rib <NUM> spaced apart from the skin <NUM> is supported by the stringers <NUM>. The rib <NUM> has a fuel containing space S3 therein. In the present embodiment, the rib <NUM> functions as a part of a fuel tank. In addition, the rib <NUM> functions as a reinforcing member that reinforces the main wing <NUM>.

The main wing <NUM> is assembled by placing the rib <NUM> on the stringers <NUM> integrated with the skin <NUM> and by fastening the stringers <NUM> and the rib <NUM> with a fastener (for example, a bolt). In the present embodiment, the main wing <NUM> is assembled by an assembling device <NUM>.

<FIG> is a schematic structural view illustrating a structure of the assembling device <NUM>, which is not within the scope of the claims.

In order to make it easier to view <FIG>, the rib <NUM> is illustrated as having a planar shape. As illustrated in <FIG>, the assembling device <NUM> includes a holding member <NUM> and a processing device <NUM>. The holding member <NUM> includes a first holding member 101a and a second holding member 101b.

The first holding member 101a is, for example, a jig, and is disposed below the skin <NUM> and the stringers <NUM> in a vertical direction. The first holding member 101a holds the skin <NUM> and the stringers <NUM> in an assembly orientation at a location below the skin <NUM> and the stringers <NUM> in the vertical direction. A reference position (a reference mark) X1 that serves as a reference for a processing position where processing is performed by the processing device <NUM> exists on the first holding member 101a.

The second holding member 101b is, for example, a jig, and is disposed above the rib <NUM> in the vertical direction. The second holding member 101b holds the rib <NUM> in an assembly orientation at a location above the rib <NUM> in the vertical direction. A reference position (a reference mark) X2 that serves as a reference for a processing position where processing is performed by the processing device <NUM> exists on the second holding member 101b.

The skin <NUM> and the stringers <NUM> in the assembly orientation face the rib <NUM> in the vertical direction. In the present example, the first holding member 101a is formed separately from the second holding member 101b and faces the second holding member 101b in the vertical direction. However, the first holding member 101a and the second holding member 101b may be integrated with each other.

As illustrated in <FIG>, each stringer <NUM> includes a first excess thickness portion 13a. In <FIG>, a design shape (a design value) DVa of each stringer <NUM> is illustrated by a broken line. Hitherto, each stringer has been formed with this design shape DVa. In the present embodiment, the shape of each stringer <NUM> is larger than the design shape DVa. A portion of each stringer <NUM> situated outward with respect to the design shape DVa is the first excess thickness portion 13a.

That is, each stringer <NUM> of the present example has a portion that is larger than the design shape DVa, and the larger portion corresponds to the first excess thickness portion 13a. Each first excess thickness portion 13a is provided close to (on a side facing) the rib <NUM> with respect to the design shape DVa of the stringer <NUM>.

In the present example, each first excess thickness portion 13a is formed by forming each stringer <NUM> larger than the design shape DVa, and is integrated with the corresponding stringer <NUM>. However, each first excess thickness portion 13a may be formed separately from the corresponding stringer <NUM>. For example, it is possible to form each stringer <NUM> with the design shape DVa, mount an adjustment member, such as a shim or a spacer, on a surface of each stringer <NUM> facing the rib <NUM>, and form the adjustment member as the first excess thickness portion 13a.

In the present example, each first excess thickness portion 13a is made of a metal. For example, each first excess thickness portion 13a is made of a metal that is the same as the metal out of which each stringer <NUM> is made. However, each first excess thickness portion 13a may be made of a metal differing from the metal out of which each stringer <NUM> is made, or may be made of a material differing from a metal. For example, each first excess thickness portion 13a may be made of a composite material.

The rib <NUM> includes second excess thickness portions 15b. In <FIG>, a design shape (a design value) DVb of the rib <NUM> is illustrated by a broken line. Hitherto, the rib <NUM> has been formed with this design shape DVb. In the present example, the shape of the rib <NUM> is larger than the design shape DVb.

Portions of the rib <NUM> situated outward with respect to the design shape DVb are the second excess thickness portions 15b. That is, the rib <NUM> of the present embodiment has portions that are larger than the design shape DVb, and the larger portions correspond to the second excess thickness portions 15b. Each second excess thickness portion 15b is provided close to (on a side facing) the stringers <NUM> with respect to the design shape DVb of the stringer <NUM>.

In the present example, each second excess thickness portion 15b is formed by forming the rib <NUM> larger than the design shape DVb, and is integrated with the rib <NUM>. However, each second excess thickness portion 15b may be formed separately from the rib <NUM>. For example, it is possible to form the rib <NUM> with the design shape DVb, mount adjustment members, such as shims or spacers, on a surface of the rib <NUM> facing the stringers <NUM>, and form the adjustment members as the second excess thickness portions 15b.

In the present example, each second excess thickness portion 15b is made of a metal. For example, each second excess thickness portion 15b is made of a metal that is the same as the metal out of which the rib <NUM> is made.

However, each second excess thickness portion 15b may be made of a metal differing from the metal out of which the rib <NUM> is made, or may be made of a material differing from a metal. For example, each second excess thickness portion 15b may be made of a composite material.

In this way, the stringers <NUM> of the present example include the corresponding first excess thickness portions 13a, and the rib <NUM> of the present example includes the second excess thickness portions 15b, the first excess thickness portions 13a and the second excess thickness portions 15b being provided for adjusting a gap between the stringers <NUM> and the rib <NUM>. The first excess thickness portions 13a and the second excess thickness portions 15b face each other in the vertical direction.

The processing device <NUM> is, for example, an NC processing machine, and performs NC processing on the first excess thickness portions 13a of the stringers <NUM> and the second excess thickness portions 15b of the rib <NUM>. In the present example, the processing device <NUM> includes a cutting tool, and cuts the first excess thickness portions 13a and the second excess thickness portions 15b. However, the processing device <NUM> may include a grinding tool, and may grind the first excess thickness portions 13a and the second excess thickness portions 15b.

When the fuselage <NUM> and the wings (the main wings <NUM>, the horizontal tails <NUM>, and the vertical tail <NUM>) of the aircraft <NUM> are to be assembled, a gap may be formed between the plurality of assembly components. Hitherto (for example, in <CIT>), the thickness of the gap between the plurality of assembly components has been measured, a shim has been manufactured by machining a workpiece three-dimensionally by a processing machine on the basis of the distribution of the measured gap thickness, and then the shim has been inserted into the gap to fill the gap with the shim.

In this way, hitherto, in order to fill the gap between the plurality of assembly components, many operational steps, such as the step of measuring the gap between the plurality of assembly components, the step of manufacturing a shim, and the step of inserting the shim, have been performed. Therefore, the assembly operation of assembling the assembly components may be complicated.

The assembly operation of assembling a main wing <NUM> by the assembling device <NUM> of the present example is described below. As illustrated in <FIG>, first, the first holding member 101a holds the skin <NUM> and the stringers <NUM> with the main wing <NUM> in an assembly orientation. The second holding member 101b holds the rib <NUM> with the main wing <NUM> in the assembly orientation.

Here, as described above, the stringers <NUM> include the respective first excess thickness portions 13a for adjusting a facing interval with respect to the rib <NUM>. The rib <NUM> includes the second excess thickness portions 15b for adjusting the facing interval with respect to the stringers <NUM>. In the assembly orientation, the first excess thickness portions 13a and the second excess thickness portions 15b spaced apart from each other in the vertical direction face each other. In one embodiment, the facing interval may correspond to a "gap".

Next, the processing device <NUM> performs NC processing on the first excess thickness portions 13a and the second excess thickness portions 15b. In <FIG>, an assembly design shape (a design value) DSa of the skin <NUM> and the stringers <NUM> in which the reference position X1 on the first holding member 101a serves as a reference is illustrated by an alternate long and short dashed lines. The assembly design shape DSa is an ideal shape in terms of design when the skin <NUM> and the stringers <NUM> in the assembly orientation are held by the first holding member 101a.

It is desirable that the design shape DVa of the stringers <NUM> above be the same as the assembly design shape DSa. However, due to, for example, manufacturing errors occurring when the skin <NUM> and the stringers <NUM> have been manufactured or distortions caused by the self-weights of the skin <NUM> and the stringers <NUM> in the assembly orientation, the design shape DVa may not be the same as the assembly design shape DSa. <FIG> illustrates the case in which the design shape DVa deviates from the assembly design shape DSa due to the effect of, for example, manufacturing errors or distortions.

With reference to the reference position X1 existing on the first holding member 101a, the processing device <NUM> processes the first excess thickness portions 13a in accordance with the assembly design shape DSa. By performing NC processing on the first excess thickness portions 13a with the skin <NUM> and the stringers <NUM> in the assembly orientation, the processing device <NUM> is capable of reducing errors with respect to the assembly design shape DSa.

In <FIG>, among the three first excess thickness portions 13a, the leftmost first excess thickness portion 13a is a first excess thickness portion 13a after being subjected to the NC processing by the processing device <NUM>. A surface of the first excess thickness portion 13a facing the second excess thickness portion 15b is cut to the assembly design shape DSa by the processing device <NUM>.

In <FIG>, among the three first excess thickness portions 13a, the middle first excess thickness portion 13a and the rightmost first excess thickness portion 13a are first excess thickness portions 13a before being subjected to the NC processing by the processing device <NUM>.

Since each stringer <NUM> includes the first excess thickness portion 13a, even if the assembly design shape DSa is positioned closer than the design shape DVa to the rib <NUM>, it is possible to perform the NC processing on the stringers <NUM> (the first excess thickness portions 13a).

Here, the height of each first excess thickness portion 13a in the vertical direction is determined by considering deviation caused by the effects of, for example, manufacturing errors or distortions of the skin <NUM> and the stringers <NUM>. For example, the height of each first excess thickness portion 13a in the vertical direction is determined by adding to the design shape DVa a value that is greater than or equal to the deviation caused by the effects of, for example, manufacturing errors or distortions of the skin <NUM> and the stringers <NUM>.

In <FIG>, an assembly design shape (a design value) DSb of the rib <NUM> in which the reference position X1 on the first holding member 101a serves as a reference is illustrated by an alternate long and short dashed lines. Here, although the assembly design shape DSb of the rib <NUM> in which the reference position X1 serves as a reference is described, the assembly design shape DSb of the rib <NUM> may be a shape in which a reference position X2 serves as a reference. The assembly design shape DSb is an ideal shape in terms of design when the rib <NUM> in the assembly orientation is held by the second holding member 101b.

It is desirable that the design shape DVb of the rib <NUM> above be the same as the assembly design shape DSb. However, due to, for example, manufacturing errors occurring when the rib <NUM> has been manufactured or distortions caused by the self-weight of the rib <NUM> in the assembly orientation, the design shape DVb of the rib <NUM> above may not be the same as the assembly design shape DSb. <FIG> illustrates the case in which the design shape DVb deviates from the assembly design shape DSb due to the effect of, for example, manufacturing errors or distortions.

With reference to the reference position X1 existing on the first holding member 101a, the processing device <NUM> performs NC processing on the second excess thickness portions 15b in accordance with the assembly design shape DSb. By performing the NC processing on the second excess thickness portions 15b with the rib <NUM> in the assembly orientation, the processing device <NUM> is capable of reducing errors with respect to the assembly design shape DSb. In <FIG>, among the three second excess thickness portions 15b, the leftmost second excess thickness portion 15b is a second excess thickness portion 15b after being subjected to the NC processing by the processing device <NUM>.

A surface of the second excess thickness portion 15b facing the first excess thickness portion 13a is cut to the assembly design shape DSb by the processing device <NUM>. In <FIG>, among the three second excess thickness portions 15b, the middle second excess thickness portion 15b and the rightmost second excess thickness portion 15b are second excess thickness portions 15b before being subjected to the NC processing by the processing device <NUM>.

Since the rib <NUM> includes the second excess thickness portions 15b, even if the assembly design shape DSb is positioned closer than the design shape DVb to the stringers <NUM>, it is possible to perform the NC processing on the rib <NUM> (the second excess thickness portions 15b). Here, the height of each second excess thickness portion 15b in the vertical direction is determined by considering deviation caused by the effects of, for example, manufacturing errors or distortions of the rib <NUM>.

For example, the height of each second excess thickness portion 15b in the vertical direction is determined by adding to the design shape DVb a value that is greater than or equal to the deviation caused by the effects of, for example, manufacturing errors or distortions of the rib <NUM>.

In this way, in the present example, the processing device <NUM> performs the NC processing on the first excess thickness portions 13a and the second excess thickness portions 15b with reference to the reference position X1 existing on the first holding member 101a. However, the processing device <NUM> may perform the NC processing on the first excess thickness portions 13a and the second excess thickness portions 15b with reference to the reference position X2 existing on the second holding member 101b.

Alternatively, the processing device <NUM> may perform the NC processing on the first excess thickness portions 13a with reference to the reference position X1, and may perform the NC processing on the second excess thickness portions 15b with reference to the reference position X2.

After the processing device <NUM> has performed the NC processing on all of the first excess thickness portions 13a on the basis of the assembly design shape DSa and all of the second excess thickness portions 15b on the basis of the assembly design shape DSb, at least one of the first holding member 101a or the second holding member 101b moves closer to the other of the first holding member 101a and the second holding member 101b.

Here, the holding states of the first holding member 101a and the second holding member 101b (that is, the assembly orientations of the skin <NUM>, the stringers <NUM>, and the rib <NUM>) are continued to be maintained. When the stringers <NUM> and the rib <NUM> come into contact with each other, the first holding member 101a and the second holding member 101b stop moving.

Here, the first excess thickness portions 13a of the respective stringers <NUM> are subjected to the NC processing to have the assembly design shape DSa, and the second excess thickness portions 15b of the rib <NUM> are subjected to the NC processing to have the assembly design shape DSb. Therefore, even if manufacturing errors occur when the assembly components (the skin <NUM>, the stringers <NUM>, the rib <NUM>) are manufactured or distortions caused by the self-weights of the assembly components in the assembly orientation occur, it is possible to reduce the gap between the plurality of assembly components that are being assembled to an NC processing precision.

Therefore, it is possible not to perform, for example, the step of measuring the gap between the plurality of assembly components, the step of manufacturing a shim, and the step of inserting the shim, and to simplify the operation of filling the gap between the plurality of assembly components.

The assembling device <NUM> causes the stringers <NUM> and the rib <NUM> in contact with each other to be fastened to each other with a fastener (not illustrated; such as a bolt). Therefore, the skin <NUM>, the stringers <NUM>, and the rib <NUM> are integrated with each other, and thus the main wing <NUM> is assembled.

As described above, the assembling device <NUM> of the present example includes the processing device <NUM>, and the processing device <NUM> processes the first excess thickness portions 13a of the stringers <NUM> and the second excess thickness portions 15b of the rib <NUM>.

Therefore, the processing device <NUM> is capable of processing the stringers <NUM> (the first excess thickness portions 13a) and the rib <NUM> (the second excess thickness portions 15b) in the assembly orientation to the corresponding ideal shapes (the corresponding assembly design shapes DSa and DSb) in terms of design. As a result, it is possible to simplify the operation of filling the gap between the plurality of assembly components and to facilitate the assembly operation of assembling the assembly components.

The processing device <NUM> processes the first excess thickness portions 13a and the second excess thickness portions 15b with reference to the reference position X1 existing on the first holding member 101a or the reference position X2 existing on the second holding member 101b.

By processing the first excess thickness portions 13a and the second excess thickness portions 15b with reference to the reference position existing on the holding member <NUM>, which is a jig, it is possible to process the stringers <NUM> (the first excess thickness portions 13a) in the assembly orientation and the rib <NUM> (the second excess thickness portions 15b) in the assembly orientation with high precision to have the corresponding ideal shapes (the corresponding assembly design shapes DSa and DSb) in terms of design.

<FIG> is a schematic structural view illustrating a structure of an assembling device 100A according to an embodiment.

Structural components that substantially correspond to those of the embodiment above are given the same reference numerals and are not described below.

<FIG> illustrates first excess thickness portions 113a after being processed into female portions on the basis of the assembly design shape DSa by the processing device <NUM> and second excess thickness portions 115b after being processed into male portions on the basis of the assembly design shape DSb by the processing device <NUM>.

As illustrated in <FIG>, in the assembling device 100A of the present embodiment, the shapes of the processed first excess thickness portions 113a and the shapes of the processed second excess thickness portions 115b differ from the shapes of the first excess thickness portions 13a and the shapes of the second excess thickness portions 15b of the example above. Since the other portions are the same as those of the assembling device <NUM> of the example above, they are not described.

The processing device <NUM> of the present modification processes the first excess thickness portions 113a and the second excess thickness portions 115b so that at least a portion of each first excess thickness portion 113a has a shape differing from the assembly design shape DSa and at least a portion of each second excess thickness portion 115b has a shape differing from the assembly design shape DSb. For example, the processing device <NUM> processes the first excess thickness portions 113a to be smaller than the assembly design shape DSa. In addition, the processing device <NUM> processes the second excess thickness portions 115b to be larger than the assembly design shape DSb.

Each first excess thickness portion 113a has a varying height in the width direction of the stringers <NUM> (in <FIG>, a left-right direction). For example, the height of each first excess thickness portion 113a gradually decreases with decreasing distance from the center of each stringer <NUM> in the width direction.

In other words, the height of each first excess thickness portion 113a increases gradually with increasing distance from the center of each stringer <NUM> in the width direction. As illustrated in <FIG>, each first excess thickness portion 113a has a hollow portion 113b having a central portion that is depressed with respect to the assembly design shape DSa. In one embodiment, the hollow portion 113b may serve as "a first position aligner".

Each second excess thickness portion 115b has a varying height in the width direction of the rib <NUM> (in <FIG>, a left-right direction). For example, the height of each second excess thickness portion 115b gradually increases with decreasing distance from the center of the rib <NUM> in the width direction. In other words, the height of each second excess thickness portion 115b decreases gradually with increasing distance from the center of the rib <NUM> in the width direction.

As illustrated in <FIG>, each second excess thickness portion 115b has a protrusion 115c having a central portion that protrudes with respect to the assembly design shape DSb. In one embodiment, the protrusion 115c may serve as a "second position aligner".

When the first excess thickness portions 113a and the second excess thickness portions 115b come close to each other, the protrusions 115c are inserted into the hollow portions 113b. Facing surfaces of the hollow portions 113b and corresponding facing surfaces of the protrusions 115c that face each other are generally parallel to each other. Therefore, when the hollow portions 113b and the corresponding protrusions 115c have come into contact with each other, the facing surfaces of the hollow portions 113b and the corresponding facing surfaces of the protrusions 115c are in contact with each other.

When the hollow portions 113b and the protrusions 115c have come into contact with each other, the positions of the stringers <NUM> and the position of the rib <NUM> in the vertical direction are determined. Here, the upper surface of the assembly design shape DSa on the upper side in the vertical direction generally coincides with the lower surface of the assembly design shape DSb on the lower side in the vertical direction.

When the hollow portions 113b and the protrusions 115c have come into contact with each other, the hollow portions 113b and the protrusions 115c are also in contact with each other in the width direction of the stringers <NUM> and the rib <NUM> (in <FIG>, the left-right direction). Therefore, the positions of the stringers <NUM> and the position of the rib <NUM> in the width direction (in <FIG>, the left-right direction) are determined.

As described above, the assembling device 100A of the present embodiment includes the processing device <NUM>, and the processing device <NUM> forms the hollow portions 113b in the first excess thickness portions 113a and forms the protrusions 115c on the second excess thickness portions 115b. In one embodiment, the hollow portion 113b and the protrusion 115c may serve as a "first position aligner" and a "second position aligner" respectively. The protrusions 115c are formed in correspondence with the hollow portions 113b. The hollow portions 113b and the protrusions 115c are formed for performing aligning in a direction orthogonal to the direction in which the stringers <NUM> and the rib <NUM> face each other (in <FIG>, the left-right direction).

Therefore, the assembling device 100A is capable of facilitating the positioning of the stringers <NUM> and the rib <NUM> in the width direction in addition to the positioning of the stringers <NUM> and the rib <NUM> in the vertical direction. As in the example above, it is possible to simplify the operation of filling the gap between the plurality of assembly components and to facilitate the assembly operation of assembling the assembly components.

In the embodiment and the modification above, the assembling devices <NUM> and 100A are described as being used to assemble a main wing <NUM> by using a skin <NUM>, stringers <NUM>, and a rib <NUM>. However, the assembling devices <NUM> and 100A may be used to assemble the other types of wings by using a skin <NUM>, stringers <NUM>, and a rib <NUM>. For example, the assembling devices <NUM> and 100A may be used to assemble a horizontal tail <NUM>, a vertical tail <NUM>, or a central wing by using a skin <NUM>, stringers <NUM>, and a rib <NUM>.

In the embodiment and the example above, the first excess thickness portions 13a and 113a and the second excess thickness portions 15b and 115b are described as being made of a metal. However, the first excess thickness portions 13a and 113a and the second excess thickness portions 15b and 115b may be made of a composite material. Here, when the first excess thickness portions 13a and 113a and the second excess thickness portions 15b and 115b are made of a metal, if the processing device <NUM> performs NC processing (cutting), an oxide film is removed.

Therefore, post-processing for applying the oxide film is performed. In contrast, making the first excess thickness portions 13a and 113a and the second excess thickness portions 15b and 115b out of a composite material is advantageous in that such post-processing for applying an oxide film after the processing device <NUM> has performed NC processing is not performed.

In the embodiment and the example above, the processing device <NUM> is described as processing the first excess thickness portions 13a and 113a and the second excess thickness portions 15b and 115b with reference to the reference position X1 existing on the holding member <NUM> or the reference position X2 existing on the holding member <NUM>.

However, the processing device <NUM> may process the first excess thickness portions 13a and 113a and the second excess thickness portions 15b and 115b with reference to a reference position differing from the reference positions X1 and X2. For example, the processing device <NUM> may process the first excess thickness portions 13a and 113a and the second excess thickness portions 15b and 115b with reference to a reference position existing on the ground.
