Week 8 - Challenge 3 - Coin Holder Design

COIN HOLDER DESIGN

AIM

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.

OBJECTIVE :

1. Creation of Tooling Axis.
2. Draft Analysis of Class A surface.
3. Creation of Class B and Class C surface.
4. Creating a solid part out of surface modelling.
5. Draft Analysis of coin holder.

CLASS A SURFACE

We get a class A surface as a input.

TOOLING AXIS

The tooling axis is defined as the direction in which the mold or core and cavity opens is the tooling axis.First create the point for the reference of tooling axis and now using point as a reference we create a line normal to the surface.

B SURFACE CREATION

Extract the side walls with no propagation in extract option.Untrim them.Extrapolate the walls with point continuity of required distance. Trim the walls to get the required shape.Offset those trimmed walls with thickness value and measure the fillets, calculate it and create fillets.

C SURFACE CREATION

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.

CLOSED SURFACE

Join the Class A and Class C surfaces.Trim those joined surfaces with Class B surfaces.Go to Part Design and insert a Body and create a closed surface.

DRAFT ANALYSIS

Go to the Insert menu and select the Analysis option.Select Feature Draft Analysis.Select the Material option and select the surface.Drag the compass and place on tooling axis.Make sure that the top surface is in green colour as draft angle should not exceed 3deg.Click on Okay after confirm the model.

• CLASS A SURFACE

• SOLID BODY ANALYSIS

RESULT

Created of Tooling Axis.

Draft Analysis of Class A surface is done .

Created of Class B and Class C surface .

Created a solid part out of surface modelling.

Draft Analysis of coin holder is done.
