Week 8 - Challenge 2 - Switch Bezel Design

OBJECTIVE:

• To design the switch bezel from the given styling surface. 
• Create the A-surface and tooling direction for the A-surface.
• Perform draft analysis on the A-surface.
• Create the B-surface and C-surface.
• Create the Core and Cavity for the Switch Bezel.

SOFTWARE USED: CATIA V5

DESIGN METHODOLOGY

Given: A-surface

       

 

• First, we need to check the given A-surface for any surface errors like open boundaries or twisted surfaces. We can use the boundary command to check for any open boundaries.
  
  

           

•  TOOLING DIRECTION: Tooling direction is the direction in which the core moves away. It is necessary to find the tooling direction of the A-surface as the B and C surfaces will be created according to the tooling direction.
  
  To find the tooling direction we need to clear the inner walls of the Bezel for 3 degrees. Draft analysis is needed to check the angles of the inner walls.
  
   
  
  
• B-surface creation: For the B-surface, we create an extrapolated surface which will be cut using the C-surface.
  
  
• C-surface creation: 
  
   
  
  
• Draft analysis on the closed body: Draft analysis on the body is performed to check the draft on the A-surface, B-surface, and C-surface. Here the Closing surface follows the draft of the A-surface.
