Week 8 - Challenge 2 - Switch Bezel Design

Aim: Create the Switch Bezel Plastic component through the given Class-A surface.

Objectives:

• To create class B & C surface for the given component.
• To form the tooling axis and capture the surface properly.
• To check the feasibility of the component with a draft of 2 degrees.

Method:

In order to obtain the proper draft analysis tooling axis is required and the following steps show how it is done.

• Ectract the base from the Class A surface
• Create a point on the surface center
• Create the tooling axis on the center using the point
• Then create a sketch with respect to the yz plane
• Create an intesection and draw line on both side with the intersection as the reference
• Using the line drawn create a bisecting line

• Now create another sketch with respect to the zx plane
• Follow the same procedure create an intersection line and then create an line on the center point with an appropriate angle

• Now we got 2 lines
• With respect to the two lines create a bisecting line and name it as tooling axis

DRAFT ANALYSIS OF CLASS A SURFACE

CONSTRUCTION OF CLASS B AND C SURFACE

• Firstly extract the top surface followed by that extract the side walls and base as well without the fillets
• Untrim all the extracted surface
• Extrapolate the extracted surface upto a cetrain distance of all the element intersecting each other

• Trim the extracted surface with respect to the class A surface
• Now offfset the trimmed surface to a certain distance of 3mm according to the thickness

This is how the trimmed surface look like

• Now find the radius of the fillet from the class A surface using the measuring tool
• The fillet value should be given in accordance with the thickness

This is how the filleted surface look like

The class B surface is created sucessfully moving on to class C surface

• Create a sweep from the class A surface in accordance with the tooling axis
• Create a sweep with an angle of 3 deg
• The sweep surface should be smooth

• Now join the class A surface and the sweep
• And then trim the class B surface with the joint surface
• The required product is obtained
• Check the surface for any opening

Using the close surface command create the surface as a closed body
