Week 8 - Challenge 3 - Switch Bezel Design

Switch Bezel design

Aim:

To design a Switch Bezel using the given class A surface

Procedure:

Check for connectivity:

The given class A surface is checked for connectivity using joint and boundary tools in catia

Tooling direction:

• Inorder to create tooling direction the face of switch bezel is extracted and a point is created in this extract
• An axis is created in this point .As the switch bezel has only three wall the tooling direction is created using sketch.
• A sketch is created in YZ axis using intersect 3D element.The side walls of the switch bezel is sketched using line and a bisecting wall is created between these two walls
• Now a sketch is created in XZ axis here a line is created at 5 deg to the walls of switch bezel.
• Now a bisectig line is created these two sketches and this line is used as tooling axis.

Draft analysis:

After creating tooling direction draft analysis is checked.

Creating class B surface:

• Extract the surface from the class A surface and untrim it if necessary do extrapolate.
• After extrapolating the surface is trimmed to required shape and then it is offsetted to 2.5mm.

Creating class C surfaces:

• Class C surfaces is created to joint class A and class B surface.It is created using sweep command(sweep-line-with draft direction) and also using draft direction and draft angle as 3 deg.
• The outer boundary of the class A is taken using boundary and swept to create class C surface in required direction.

Final output:

• After creating surface C the surface A and surface C is jointed and then it is trimed using surface B.
• After getting required shape the surface is thicken using closed surface tool in part workbench.

Final draft analysis of the solid part:
