Background
The arc-shaped empennage is one of key parts of an aircraft and is a complex structure part with the characteristics of thin wall and nonlinear arc surface. The blank material of this arc fin is TC4 forging, and at present, the difficult problem that puzzles this part of arc fin processing manufacturing has two points: 1. the two side surfaces of the part are large-angle thin-wall and nonlinear cambered surfaces, so that the processing difficulty is great; 2. because the part is a thin-wall part, the thickness of the thinnest part of the part is only 0.0028mm, and the processing stability and the vibration resistance are difficult to ensure.
At present, the production means for the arc-shaped empennage is as follows: and (4) processing the cambered surfaces of the two side surfaces of the TC4 forge piece by using a ball-head cutter of a three-axis numerical control milling machine. Because the cambered surfaces on the two sides of the arc-shaped tail wing are extremely complex nonlinear cambered surface structures, the machined cambered surfaces cannot be completely consistent with the pre-designed cambered surfaces, the arc-shaped tail wing is a thin-wall part, the problem of insufficient rigidity also exists, the surface quality of the cambered surfaces is poor due to vibration generated in the machining process, and the machining quality is difficult to guarantee.
Based on the above, the present invention provides a novel method for manufacturing a nonlinear curved tail wing to solve the disadvantages and limitations of the prior art.

The invention provides a method for manufacturing a nonlinear arc-shaped empennage, which comprises the following steps:
s1, grinding the blank material to form a cuboid blank shape as a processing positioning reference of the subsequent process;
s2, manufacturing a tool matched with the shape of the blank in the S1, and using the tool as a position reference and a pressing device of a subsequent process; the appearance of the blank is assembled on the tool, and the tool plays a role in clamping and positioning;
s3, roughly machining the upper side surface and the lower side surface (the first side surface and the second side surface) of the blank shape by adopting a five-axis numerical control machining center to preliminarily form an arc-shaped empennage;
s4, performing finish machining on the first side surface of the arc-shaped empennage;
s5, fixing the first side surface of the arc-shaped empennage on a tool, and performing finish machining on the second side surface of the arc-shaped empennage;
s6, grooving, perforating and cutting off the arc-shaped empennage by adopting a wire electrical discharge machining method;
and S7, positioning the arc-shaped empennage by adopting a drill jig, and drilling a side through hole on the arc-shaped empennage to obtain the machined arc-shaped empennage.
As shown in fig. 2 and 3, in S2, a groove matching with the blank shape 2 is formed in the tool 1, the end of the blank shape 2 is embedded in the groove of the tool 1, and is pressed and fixed by the pressing plate 3.
S2, blank appearance 2 is above downside, both sides side to and the terminal surface of non-processing is the benchmark, and the recess phase-match of frock 1, and the fit tolerance is within 5 silks.
In the step S2, the side wall and the bottom surface of the groove of the tool 1 have a positioning function, so that the positioning accuracy of the blank shape 2 in the process of being processed into the arc-shaped empennage is ensured; the side wall of the groove of the tool 1 controls the positioning of the blank shape 2 in the X, Y direction during clamping; the surface of the bottom of the groove of the tool 1 controls the positioning of the blank shape 2 in the Z direction during clamping.
In S3, after the first side surface and the second side surface of the blank shape 2 are roughly processed, a single-side margin of 0.1 needs to be reserved to ensure the rigidity requirement.
In S4 and S5, the precision required for the design is ensured after finishing the first side surface and the second side surface of the arc-shaped tail wing.
As shown in fig. 4, in S5, the first side surface of the arc-shaped tail wing 4 is fixed on the groove of the tool 1 by using solid glue, so as to prevent the thin-walled arc-shaped tail wing from vibrating due to insufficient rigidity during the processing.
The step S6 specifically includes the following steps:
s61, first pass: processing a root groove of the arc-shaped tail wing to form a root appearance, and drilling a through-wire hole on the arc-shaped tail wing in situ and slotting the middle part;

s63, the third time: the remaining shape of the first side surface of the arc-shaped tail wing is cut off by cutting off the remaining shape of the other half of the side wall after the arc-shaped tail wing is connected in a flat way along the arc-shaped shape of the arc-shaped tail wing.
The flattening specifically means that the processed arc surface is butted to form a surface with the same radian, so that processing marks cannot be seen.
As shown in fig. 5, in S7, the jig 5 is completely matched with the root profile 6 of the arc-shaped tail fin 4, and the tip 7 of the arc-shaped tail fin 4 is fixed to the jig 5 to perform sidewall through-hole machining, so as to finally obtain the machined nonlinear arc-shaped tail fin as shown in fig. 1.
