First, in the first step S1, the lower end of the workpiece 10 is machined. Specifically, the lower end portion of the workpiece 10 is machined to join the jig 20, which will be described later.

2 is a perspective view showing the material 10. As shown in FIG. 2, the material 10 has a rail 11 formed at both ends in a longitudinal direction at a lower end thereof, Thereby forming a groove 12.

The shape of the rail 11 provided at the lower end of the material 10 is fixedly engaged with the guide 24 of the jig 20 and the groove 12 of the rail 11 is fixed to the protrusion 25 of the jig 20 ) So that the material is always positioned at a certain position.

Next, in the second step S2, the processed workpiece 10 is fixed to the jig 20. Specifically, the processed workpiece 10 is fixed to the upper end of the jig 20.

The jig 20 includes a base plate portion 21 serving as a base and fixing plate portions 22 and 23 installed and fixed to an upper end of the base plate portion 21.

3 is a perspective view of the fixing plate portions 22 and 23 that are part of the jig 20. As shown in FIG. 3, the fixing plate portions 22 and 23 include a first fixing plate portion 22, And the second fixing plate 23 which is fastened to the fixing plate portion 22 in the longitudinal direction.

The fixing plate portions 22 and 23 are provided with a guide 24 formed when the first fixing plate portion 22 and the second fixing plate portion 23 are fastened in the longitudinal direction, (25) protruding from the base (22).

The first fixing plate portion 22 is fixed to the upper end of the base plate portion 21 to support the fixing plates 22 and 23.

The second fixing plate portion 23 is engaged with the first fixing plate portion 22 in the longitudinal direction and is movable so that the material 10 can be freely detached from the jig 20.

The guide 24 is formed in a shape corresponding to the rail 11 so that it can be engaged with and fixed to the shape of the rail 11 when the workpiece 10 is fixed to the jig 20, Is engaged with the groove (12) in a shape corresponding to the groove (12) so as to be double-fixed.

A plurality of fine protrusions may be formed in the guide 24 to support the material so that the material does not flow.

The fixing process of the jig 20 of the material 10 will be described in more detail as follows.

First, the second fixing plate portion 23 is detached from the first fixing plate portion 23 of the jig 20 in Step 2-1.

In the next step 2-2, the shape of the rail 11 of the workpiece 10 is coupled to the guide 24, and the center point is held and engaged so that the groove 12 and the projection 25 are engaged with each other.

In the next step 2-3, the second fixed plate part 23 is fastened to the first fixed play part 23 in the longitudinal direction so that the processed material 10 is fixed to the fixed plate 23, So that it can be tightly fixed to the portions (22, 23).

The material 10 is processed into the form of a rail 11 and fixed to the jig 20 and then subjected to a molding operation so that a component for establishing a separate material (a boldhole fastening portion or the like) It is possible to reduce the loss of the material 10 and thus to reduce the raw material.

In addition, since the processed material 10 is fixed to the jig 20 to manufacture a navigation light housing, the overall shape is formed while the interference is minimized, and the length of the tool to be used is optimized, Is minimized.

Next, in the third step S3, the edge of the fixed workpiece 10 is cut. Specifically, the edges of the lower end portion and the upper end portion of the fixed workpiece 10 are cut.

Next, in the fourth step S4, the outer shape of the fixed workpiece 10 is roughed. Specifically, the upper surface and both side surfaces of the cut fixed material 10 are shaped as shown in Fig. 5 using a tool. It is possible to shorten the time required for shaping the outer surface through the roughing process.

Next, in the fifth step S5, the upper surface and both side surfaces of the fixed workpiece 10 are finished. Specifically, the upper surface and both side surfaces of the roughly fixed workpiece 10 are finely shaped by using the end portions of the tool, and are formed as shown in FIG.

The upper surface and both sides finishing processes prevent deformation due to vibration and provide luster to the upper surface and both side surfaces of the work 10. [

Next, in the sixth step S6, the fixed material 10 is marked to form a hole. Specifically, a hole for machining a plurality of holes is marked on the side surface of the fixed material as shown in FIG.

The side portions of the fixed material 10 made of a curved surface are marked by using the end mill to prevent slippage that occurs when the holes are machined on the side portions of the fixed material to be processed later.

The marking step is performed on the fixed material 10 in order to prevent errors in the operation in the subsequent steps, and marking the part where the holes are to be formed, rather than forming the holes.

Next, in the seventh step S7, the bottom edge of the upper surface of the fixed workpiece 10 is roughed. Specifically, the bottom edge of the upper surface of the workpiece 10 marked with a hole in the side surface is roughly ground using a tool.

Next, in the eighth step S8, the upper surface bottom edge of the fixed workpiece 10 is finely finished. Specifically, the edge of the bottom surface of the upper surface of the roughly fixed workpiece 10 is finely cut as shown in Fig. 8 by using the end portion of the tool.

The finishing process of the top surface bottom edge serves to prevent deformation due to vibration and to impart gloss to the bottom edge of the upper surface of the work 10. [

Next, in the ninth step S9, the inner bottom surface of the fixed workpiece 10 is roughed. Specifically, the bottom of the inner surface of the fixed workpiece 10 finishing the top surface bottom edge is rough-cut as shown in Fig. 9 using a tool.

Next, in the tenth step S10, the inner bottom surface of the fixed workpiece 10 is finely ground. Specifically, the bottom surface of the inner surface of the fixed workpiece 10, which roughs the inner bottom surface, is finely cut as shown in Fig. 10 using a tool.

Next, in the eleventh step S11, the inner side of the fixed workpiece 10 is finely finished. Specifically, the inner surface side of the fixed workpiece 10 finishing the inner bottom is finely cut as shown in Fig. 11 by using the side surface portion of the tool.

Next, in a twelfth step S12, a hole is formed in the fixed material 10. [ 12, a hole is formed on the bottom surface of the inner surface of the fixed workpiece 10 in which the inner surface side is finished. Then, in the sixth step S6, .

Next, in a thirteenth step (S13), the lower side of the side of the fixed workpiece 10 is finely processed to form a penetration part 13. [ Specifically, by using the pocket machining in which the side lower portion of the fixed material 10 on which the holes are formed is finished using the side portions of the tool, and then the three-dimensional pockets (grooves) are machined by using an end mill or the like, The penetration portion 13 is formed in the above-mentioned material.

Next, in the fourteenth step S14, the corners of the fixed workpiece 10 are machined. Specifically, the corner portion of the workpiece 10 having the penetrating portion is cut as shown in Fig.

Next, in a fifteenth step S15, the corners of the fixed workpiece 10 are finely cut. Specifically, as shown in Fig. 15, the center of gravity of the corner is finely cut by an R-machining process to remove the acute angle and round it.

Next, in the sixteenth step S16, the lower end of the fixed workpiece 10 is cut. Specifically, the lower end portion of the fixed work 10, in which the corner portion is finished, is cut as shown in FIG. 16 to manufacture a navigation light housing.
