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.

REPORT ON DRAFT ANALYSIS:

Given Class A Surface:

Check the connectivity of the Class A Surface
Ensure that there is no gap between the component, using join command.
We can visually check it or by clicking boundary command.
It has 3 boundaries one outer and two inner circle boundaries.
Therefore first check completed.

Tooling Axis:

The tooling axis is the tool movement axis (core/cavity).

This axis will decide the draft direction.

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

BISECTING LINE

Create a bisecting line for the inclination lines

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

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:
