SWITCH BEZEL DESIGN

Aim -

Create the Switch Bezel 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.

Method Followed -

• Creating a tool axis.
• Creating Class B surface from given Class A surface.
• Creating Class C surface from Class A & B surface.
• Creating a solid body by using a closed surface.
• Performing a draft analysis.

Creating tool axis -

• To create the tooling axis, we need the proper orientation or view that gives the correct features and draft available in the component.
• So here the component view from the Z direction gives the proper view for the tool to see the features present in the geometry.

The tooling axis is created by the following steps -

Extracted the base surface.

The Center point is created by using a surface at zero.

At that point, an axis system is created.

Take an intersection on the YZ plane to get a boundary line.

Made a dummy axis line to form a tooling axis by bisecting two lines.

After that, I switched the surface and sketched on the XZ plane.

Using the axis center point, a line is drawn in sketch mode and it is constrained at the angle of 4 degrees.

At last, both the lines are bisected to get the Final tooling axis.

• We extracted a Class A surface and worked on it separately to create Class B surface

• Base
• Walls
• Bezel rest surface

• Base -

• Extract the surface
• Untrim the surface
• Extrapolate it
• Offset it by 2.5mm to the downward.

• Walls -

• Extract the three walls separately
• Untrim the surface of three extracts
• Extrapolate them
• Trim them with each other.
• Offset the given surface by 2.5mm to the outward direction.

• Bezel rest surface -

• Extract it
• Untrim the surface
• Extrapolate it
• Offset by 2.5mm to the downwards.

Trim the Walls, Base, and Bezel rest surface to get Class B and give edge fillets of R14 and R15 by calculating the fillet value. The Class B surface is given in the below image.

• Creating Class C surface from Class A & B surface -

Extract the boundaries of the Class A surface by using multiple extracts and make their smooth curves.

• Final join -

First of all, join the Class A and Class C surfaces together.

Then trim them with a Class B surface.

• Creating a solid body by using a closed surface -

A solid body is created by a closed surface feature in the Part Design workbench in the defined part body. This is our design output shown as given below in various orientations(Isometric view, Front view, Side view & Top view).
