Development of 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

MAIN TREE:

OBJECTIVE 1: Create a Tooling Axis for the Class A surface.

TREE:

• Create a point on the class A surface to move the main tool for component creation on the base surface.
• Mask an axis over the point created with the same directions as the main axis.
• Using Intersect command from Generative Shape design select the YZ plane as the first element and the class A surface as the second element.
• After creating the intersecting lines select the Line command and join the vertices which show the most possible draft angle manufacturable.
• Bisect those two lines over the axis point we created.

OBJECTIVE 2: DRAFT ANALYSIS of Class A surface:

PROCEDURE:

• After Tooling Axis Select the Feature Draft Analysis option from the Insert Option.
• Select the element to analyze.
• Next click on Use the compass to define the new current draft direction option and make it align with the tooling axis by dragging it to the axis.
• If the color appears blue just click the invert option on the right side of the draft direction axis button.

Objective 3: Create a CLASS B SURFACE :

TREE:

PROCEDURE:

INNER WALLS:

TREE:

Using the Extract option select the first set of ribs from the Class A surface.

Then use the untrim surfaces command to restore the surfaces up to the limit.

After that click the Extrapol command to extract the surface in the curvature direction.

Finally use the trim command to cut the surfaces to get the desired output.

Set an offset to set a thickness of 2.5mm.

Fillets are given according to the CLASS A surface and considering the thickness.

Similarly proceed to do the same for the rest of the parts final part is shown below each respective tree.

BASE:

TREE:

OUTER WALLS:

TREE:

CONNECTING WALLS:

TREE:

After this, all sides are trimmed with each other and finally, a top surface is cut to create a final CLASS B surface.

We got the final CLASS B Surface.

Objective 4: Creating a CLASS C SURFACE

TREE:

Here all the outer boundaries are extracted according to the requirements.

Using sweep command with a reference surface we get the CLASS C surface.

OBJECTIVE 5: COIN HOLDER CREATION

TREE:

Trim all class A, B, and C surfaces:

To create a hole on the holder we extract the hole boundary from the class A surface and sweep with surrounding surfaces as reference.

Again trim and we get our final surface and convert it to a closed surface.

Objective 6: DRAFT ANALYSIS of the SOLID part

• Select the element to analyze.
• Next click on Use the compass to define the new current draft direction option and make it align with the tooling axis by dragging it to the axis.

CONCLUSION:

Created a CENTER CONSOLE COIN HOLDER Plastic component through the given Class-A surface.
