Week 9 - Challenge 1 - Base Bracket Design

Aim:

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

Class-A surface given

TOOLING AXIS

Create a bisecting line

• A geometrical set with the name base bracket was created and then the whole class A surface was separately extracted.
• The same extracted surfaces were then untrimmed to get a complete surface and then extrapolated so that trim command could be successfully performed.
• sides at a time were trimmed to get the below surface which was offsetted to 2.5mm.

DRAFT ANALYSIS

In plastic design, the draft analysis or angle that is considered in the OEMs is 3 degree.

First thing to carry out was to select the compass and set it on the tooling axis in upward direction.

• Draft analysis on the solid part resulted in green.
• The green region shows the part which is toolable or produceable by the molding machine and the draft angle is 3degree.
• Red color which is not there in this case states that the draft angle is less than 3 degree and cannot be produced or if produced would be faulty.
