1.Title of the invention
Method of fabrication of canopy roller bracket by conventional means resulting in reduction on cost of fabrication
2.Field of invention
This invention is related to the.manufacturing, repair and quality assurance of Canopy Roller Bracket. The method relates to precision drill jig for fabrication of canopy roller bracket.
3.Use of invention
This invention would enable fabrication of the canopy roller bracket using conventional means of machining thereby avoiding the use of expensive JIG BORING (CNC) machines. This, in turn results in reduction in cost of . fabrication.
4. Prior art
In the prior method, the drilling operation required for the fabrication of canopy roller bracket was done on expensive JIG BORING (CNC) machines and also it required skilled labor for this task.
5.Draw backs of prior art
As the drilling operation was required to be carried out on expensive JIG BORING (CNC) machines, the cost of fabrication of canopy roller bracket was high.
6.Comparison between prior art arid present invention
The prior method was extremely expensive as it required expensive JIG BORING (CNC) machines and skilled labor. The invention of the method with

the help of the drill jig eliminates the use of expensive machines skilled labor resulting in reduction in the cost of production of the canopy roller bracket.
7.Aim of the invention
Aim of the invention was the reduction in cost of fabrication of canopy roller bracket with the help of a drill jig.
8.Summary of the present invention
The method of getting the drilling operation done using the drill jig led to considerable savings in the cost of production of the canopy roller bracket as compared to the earlier method of getting the drilling operations done on JIG BORING (CNC) machines.

FIG.2 illustrates the standalone drill jig
FIG.3 illustrates the drill jig with the loaded component.
10.Statement of invention
The method of drilling operation by using the drill jig led to reduction in the cost of production of canopy roller bracket as it employed conventional techniques as well as employed unskilled labor.
11.Detailed description of invention
a)The Canopy roller bracket depicted in Figure 1 is a critical component (i.e. a Class A part) used in the opening & closing of the canopy of aircraft.
b)It consists of three holes which have very close tolerance. JIG BORING (CNC) machines had to be employed for the drilling operation which required very high precision due to its criticality of the component.

c)Further, highly skilled labor was required to be employed for completing the
drilling operation on these JIG BORING (CNC) machines.
d)A high precision drill jig shown in Figure 2 was fabricated for drilling the
precision holes.
e)The drilling operation was done with high precision using the drill jig, thereby, avoiding the use of JIG BORING (CNC) machines for the same. Also, unskilled labor could be employed in place of skilled labor. All these factors drastically reduced the cost involved in fabrication of the canopy roller brackets.
f)The drill jig consists of two guide bushes which are precision drilled to have the required diameters and pitch.

Claims
We claim
1.The Drill Jig which has enabled the fabrication of Canopy Roller Bracket by Conventional Means rather than JIG BORING (CNC).
2.The method of fabrication of the Canopy Roller Bracket.
