Week 8 - Challenge 3 - Coin Holder Design

Aim:

To create the Coin Holder 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.

Given File:

Tooling Direction:

Extract base from class A surface and created one point on the surface, Draw a line perpendicular to the surface which is your tooling direction.

Draft Analysis:

Class B and C surface creation:

Class B Surface:

Extract the rest surface and used untrim option to take full surface after that offset the same 2.5mm downward.

Again, Extract Class A surface wall and untrim all the wall.

Extract all the surface to the required dimension with Point continuity and offset them 2. 5mm.Then trim them for getting required surface.

For Base also used same operation after than all the surface trim to get required surface.

Given required edge fillet.

Class C Surface:

Create a boundry using the given class A. Now with the sweep option we can create a surface perpendicular to the tooling direction to join the two surfaces.

Now trim class B with class C

And then to get final surface trim it with class a.

Now use the closed surface command in the part workbench to create a solid body from the final surface.

Perform Draft Analysis on the final model.

This is the result obtained for the given class A model. The class A model itself having some issues with the Drafting analysis.
