Week 8 - Challenge 3 - Coin Holder Design

CHALLENGE 23 – COIN HOLDER DESIGN & DRAFT ANALYSIS

Aim: Given Class A input surface, complete the thickened Coin Holder part and perform draft analysis on the completed part.

CLASS A SURFACE

We were provided the Class A Surface as below.

Fig 1 – Original Class A Surface before Translation

We then created a Tooling Axis simply by taking the Normal to the bottom surface of the coin holder.

Thickened Part

After creating the Tooling Axis, we created the Class B and Class C surfaces and trimmed them with the Class A surface. For the Class B surface, we started with the base, then added the Boss, Side Walls, and finally the Outer Flange (Upper and Lower). Finally, we used Close Surface to produce a final, thickened, solid part.

The Draft Analysis validated the design for manufacturability.

Conclusion: We were able to successfully model the part and verified it for Draft Analysis.
