Week 8 - Challenge 4 - Coin Holder Design

Aim: The aim of this project is to create a tooling axis for the given part and to make it a solid body of prescribed thickness.

Objectives: Using the given Class A surface, create a tooling axis and make it

a solid body of prescribed thickness.

Design Methodology with images:

Procedure for creating Tooling Axis

1. Intersect the model with the plane perpendicular or to an axis system.

2. Extend the lines which are perpendicular to the plane.

3. Again intersect the model with another plane and extend the lines perpendicular to it.

4. Create a bisecting line by bisecting option in Line definition.

5. Rename it as Tooling Axis.

Procedure for creating B Class surafce

Side Walls Walls

• Extract the side walls with no propagation in extract option.
• . Untrim them.

Extrapolate the walls with point continuity of distance 20mm.

• Trim the walls to get the required shape.

• . Offset those trimmed walls with thickness value.

Top & Bottom Surfaces:

• Extract the surfaces separately and untrim them.

Extrapolate the surfaces with required distances.

.Offset them with thickness value.

• Trim them for required shape.

. Measure the fillets, calculate it and create fillets.

Procedure for creating Class C Surface:

• Get the boundary lines of Class A surface separately.

• Smooth the curves with a smooth option as boundary lines have a lot of vertices.

• Sweep the curves with tooling axis as direction in Sweep option.

• As both lines do not intersect, extrapolate them with a certain distance.

• Trim the surfaces.

Procedure for creating Closed Body.

Join the Class A and Class C surfaces.

• Trim those joined surfaces with Class B surfaces.

• Go to Part Design and insert a Body.

• Create a closed surface.
