Week 9 - Challenge 1 - Base Bracket Design

KKeshav Bansode18 Apr 2023

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 mode.

Class-A surface:

Visible surface and aesthetic look.
Surface provided by customer (OEM).
Surface with textures.
Don't have any features like rib, snap, bosses etc on class A surface.

Class-B surface:

Invisible surface.
Surface mostly don't have textures.
Surface need to be created according to class-A surface.
Having all features bosses, snap, rib etc in B side surface only.
Surface which is having tangent continuity is call class-B surface.

Class-C surface:

join to Class-A and Class-B surfaces.

We have focused on the following things:

Tooling axis
Draft analysis
Class-A surface
Class-B surface
Making a solid model from surface.

Following tools were used to reach the final step:

Extract
Un-trim
Trim
Extrapolate
Offset
Edge fillet
Boundary
Sweep
Join
Close surface

For Tooling Axis:

First ensure the class-A surface is properly joined and has no discontinuity on it. For this we can use boundary command or join command.
Analyze the model manually or visually to see which direction is most suitable for tooling axis.

As in 3D view, we can see 2 hole and a flat surface, we can directly take the tooling axis perpendicular to that. But to be sure, Let us a laze from all the view. the below image's the front side and top view shows the area that we have to keep in mide while choosing tooling axis. As from X we cannot see one hole so we cannot take axis along this. In Y we cannot see any hole so here to we cannot tooling aixs. But in Z we can see 2 hole and flat surface so we can taker tooling axis.
