Week 8 - Challenge 1 - Base Bracket Design

AIM

To Create the Base Bracket Plastic component through the given Class-A surface.

TOOLING AXIS

To create the tooling axis we need study the class A surface and there is no gap between the surface. Create the point on the surface after create the dummy tooling axis.If there circle we can create the tooling axis on hole center.

BISECTING LINE

Create the intersect line on the CLASS A surface using the intersect command. After create the bisecting line with reference the lines after ecxtended center line will create between two reference line. That extended line is our Bisecting line.

DRAFT ANALYSIS:

Draft analysis used to analysis the part for proper draft angle. It has 3 colour scale green blue and red and maximum draft angle up to 3deg.Finally fix the comopass on tooling axis on Class A surface.

Class B surface
I perform in this surface in 3 ways
1)Rib-1
2)Rib-2
3)Surface

Rib-1
From class A surface i perform the 5 operation.
Extract,Surface trim,Extrapolate,Trim and Offset.
Offset done by 2.5mm.

Rib-2
From class A surface i perform the 5 operation.
Extract,Surface trim,Extrapolate,Trim and Offset.
Offset done by 2.5mm.
Same as Rib-1

Surface
Surface is also same process as do in Rib.

Final trim 

Now we have perform the trim operation and edge fillet command to make B'surface output.

Class C surface

During C surface creation we have extract the boundry surface from the Class A for creating this surface i use sweep command, In sweep command we have to give 3 deg in the angle because the draft angle for a plastic component is 0.5 to 3 deg.
