Week 8 - Challenge 1 - Base Bracket Design

 Week 8 - Challenge 1 - Base Bracket Design

AIM:- Create the Base Bracket Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model. 

CLASS A SURFACE:-

A point was created at the center of the large circle, Using that axis system is inserted

Tooling axis

Using the ZX plane an intersection is to be made.

Two lines need to be created from the points-take any two of the incline lines as reference,

create a main tooling axis using bisecting line in this case the tooling axis is red dotted line 

 Class B surface

Now creating Class B Surface:

Intially extracting the right side rib using extract option from Class A surface.

Then perform Extrapolate inorder to increase the length

Now trim the surfaces to required surfaces

Then Offset the surface inorder to get the required thickness (2.5)

Similary create the left side rib

Now Similarly get the slanted as well as the flat surface and offset it to desired value

And now trim inorder to get the required surface

Now fillet the surface to required amount

Class c surface 

Create the outer surface by boundary and sweep and also create circular hole using boundary and sweep

Then above image is the join of A and C that is join AC

Closed surface

above image show  the final  trim of the final plastic body created by trim/joining (Join AC)and Class B

The final plastic body  trim is created into solid using solid surface command 

1.Draft analysis of Class A Surface

 The draft angle for class a surface is 3

2.1Draft analysis of  solid plastic body with unevenness red patches

2.2Draft analysis of  final solid plastic body(Updated final surface without uneven red patches) draft angle 2.7

The draft angle for final plastic body is taken 2.7 to remove red uneven marks
