Week 8 - Challenge 1 - Base Bracket Design

Aim:

To be able to create solid from the given Class-A surface, by considering tooling axis and draft analysis.

Class-A surface given:

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 bisecting line for the inclination lines,

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

This axis will decide the draft direction.

The above picture is the result of the draft analysis.

The draft is considered as 3 degrees.

Class B surface:

 

by extracting the surfaces from class A and then offsetting the extracted surface we got a Class B surface that is 2mm below class A.

Class C surface:

By using the boundary Sweep is created.

And the angle of draft given in Sweep is 3 Degrees.

Closed Surface:

The above surface is trimmed/join from the Class A,B,C surfaces.

The Solid is made by using the Close surface tool.

Draft Analysis for solid:
