Week 9 - Challenge 2 - Switch Bezel Design

In this project, I design a Switch Bezel using Catia v5. I received input as Class A Surface. I Check the direction to eject the tool based on the component design. Later I checked whether all faces that intersected will clear the direction based on the tooling axis. I started working on the Draft Analysis tool to check if our tooling direction clears the path for easy removal of material from the tool. After that, I go class B creation using Advance tools from the surface followed by class C creation using the sweep command. after design A B C class surface, converting close surface into solid inside the part workbench

Procedure for creating Tooling Axis

1. A Reference Point is created along the Surface zero and new Axis system is created 
2. The X Direction along the Class A and Y direction along the Class A were used to create Tooling direction
3. Finally the Tooling axis is created by bisecting the two lines and it is published. Class A Surface as input using surface operation commands Class B is developed
4. The tooling Axis determines the direction of Class C boundary swept with draft direction.
5. When viewing from tooling direction normal all the parts that are drafted should be visible so it gives an rough idea to determine product manufacturing in Injection molding.

Procedure for B Surface Creation

• The next step is to design B surface for the input which is usually the surface where all engineering aspects and support creations are done.
• The B surface Creation is performed using surface operations in CATIA which is an offset from Class A with dimension proportional to the thickness of the part 
• In Switch bezel the B surface is offset 2.5mm from the input which is the thickness of the part 
• The B surface is an extrapolated surface compared to A surface and forms the bottom skin of the part.
