Week 8 - Challenge 1 - Base Bracket Design

DRAFT ANALYSIS :

The draft analysis technique is used to analyze whether our part model created in CAD is manufacturable based on the draft condition applied. Here the part should get easily removed from the panel dies (in case of Sheet metal part) or Mold (in case of plastic).

No parts can be ejected from the tool if it is having a straight 90-degree profile from its base surface. A small draft angle is provided to each and every area of the component in order to get easy removal of the component from the tool.

DRAFT ANALYSIS OF CLASS A SURFACE :

TOOLING AXIS :

Now we need to create the tooling axis for the base bracket model. Visually check which direction is better for creating tooling axis. First create a dummy tooling axis in Z direction.

Next we need to create the YZ plane at the required point. After that create the intescton line by using the created plane to the class A surface.

Now create line through the walls of a base bracket using point to point option with the help of intersect 1 where you thank the tooling might create problem.

Now using these 2 lines create a bisecting line from reference point in Z direction. This will form a main tooling axis in Z direction.
