Week 8 - Challenge 4 - 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.
Take the Thickness of the component to be 2.5 mm.

PROCEDURE:

CHECK THE CONNECTIVITY OF CLASS A :

TOOLING AXIS :

Now we need to create the tooling axis for the Center Console Coin Holder model.
Visually check which direction is better for creating the tooling axis. Now in order to create the tooling axis in Z - direction
First creates a reference point on any surface as shown in below.

Now using the reference point, create a line normal to the surface. This line will give us the tooling axis.

CLASS B SURFACE :

SIDEWALLS :

FILLETS :

Fillets measure the class a surface and give the fillets it by required values.

BASE :

Once the base surfaces are Extracted, Untrim and Extrapolate it by 20 mm on each side using point continuity.
Offset it by 2.5 mm.
Trim them to form the proper base.

BASE WALLS :

Base walls are Extracted, Untrim, and Extrapolate by 10 mm on each side using point continuity.
Trim them to form a proper base wall.
Offset it by 2.5 mm.
Offset trim with a base surface.
Replace trim 2 with trim 12.
Local update in trim 3.

Sidewalls trim with Base Surface.

TOP WALL:

Top walls are Extracted and Extrapolate by 20mm on each side using point continuity.
Extrapolate by 4 mm.
Offset it by 2.5 mm.
trim 3 with offset.

CLASS B SURFACE :

Once all the surfaces are created trim these surfaces to form a Class B surface.
Give the appropriate fillets to form a Class B surface.

Class C Surface :

To create the Class C surface first, extract the boundaries of the Class A surface and extract the adjacent surfaces to the boundary as shown below.

Sweep:

Now using the sweep option create the surface.
To perform this operation, Go to the Toolbar > Sweep > Profile type > Line > Subtype > With reference surface > Guide curve 1 - (select the extracted boundaries) > Reference surface - (select the extracted surface) > angle and length as 90 deg and 4 mm respectively and click ok.

Hole:

To create a hole first, extract the boundary of the hole and extract the adjacent surfaces to the boundary as shown below.

Sweep:

Now using the sweep option create the surface.
To perform this operation, Go to the Toolbar > Sweep > Profile type > Line > Subtype > With reference surface > Guide curve 1 - (select the extracted boundaries) > Reference surface - (select the extracted surface) > angle and length as 90 deg and 4 mm respectively and click ok.

Final trim:

At last, Class A and Class C surfaces were joined together and trimmed along with the class B surface.
Thus a closed surface was formed as shown below.

Now using the close surface from the part workbench form a solid body from the surface body.

Draft Analysis:

To perform Draft Analysis on the Center Console Coin Holder model, first set the view parameters to Material Mode.
Then Go to the menu bar > select insert > Analysis > Feature Draft Analysis.
To give the draft direction, use the compass and align the Z-axis of it with the final tooling axis for the Center Console Coin Holder model.
Once it is properly aligned, lock the draft direction.
Select the Center Console Coin Holder and it will show us the current draft angle of the model.
Set the draft value to 2.8 deg under the colour scale variant and press ok.
