Week 8 - Challenge 3 - Switch Bezel Design

Challenge - Switch Bezel Design

Objectives: 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 CLASS B & CLASS C SURFACES and to make a solid body from the surface

CLASS A SURFACE Switch Bezel Design

Tooling axis on a Switch Bezel Design

Input the class A surface of base bracket model in CATIA

First, create the point (reference point) on the Base extracted surface and create a dummy tooling direction in the Z direction

Create two sketches ( one sketch in the YZ plane and another sketch in the XZ plane)

Draw two lines as shown in the below fig and these lines help to bisect the midline and create a real TOOLING AXIS

CLASS B SURFACE

For creating a Class B surface extract the class A surface of Walls & base (individual surfaces) considers offsetting the thickness of the component as 3mm. Offsetting the extracted surfaces and UNTRIM the Extracted offset surface using the UNTRIM tool. Extrapolate the untrimmed surface for trimming the Ribs and Base surface. The final output of Class b surface as shown in below fig

The final output of Switch Bezel B surface

CLASS C SURFACE

To create a Class C surface, extract the Boundaries of a Class A surface as shown in figure

Create the surface using the sweep tool

For the sweep, tool Go to the tool bar>sweep>profile type> line >subtype>with draft direction select the guide curve (Extract boundaries)

SOLID PART BODY OF Switch Bezel Design

Finally using Close surface tool form part workbench for converting surface body to solid body
