Week 8 - Challenge 3 - Switch Bezel Design

Aim-To create the switch bezel plastic component through the given class-A-surface and at the end performing the draft analysis on the model.

Objectives-

• To ensure proper tree structure is followed.
• Geometrical sets should have a proper name based on the sketches present inside of it.
• All the sketches should be created under geometrical set.
• Use of the close surface feature to make a solid body from the surface.
• To publish the tooling axis ,Class A,B and C surface.

Tooling axis creation

The tooling axis is the direction of drawing a sheet metal where the finished component is easily ejected on a particular direction and axis. The tooling axis is important for removing the material when finished.

The tooling axis is created for the given class-A surface.

Creation of tooling Axis (Bisecting method)

1. Extract the base surface of the given Class- A Surface and create the center point of the Extracted surface.

2. Then create two sketches on two planes by taking the cross section of the given surface in the particular plane.

tooling axis created from the two lines using the cross section of the surface on y plane as bisecting line.

tooling axis created from the two lines using the cross section and also creating one with the help of cross section line of the surface on X plane as bisecting line.

And now by creating another bisecting line using those two plane sketches is the tooling axis for this particular Class - A surface.

Creation of Class - B and Class - C surfaceE

extracting the class - A surface without the fillets and then untriming and extrapolateing them to join them, and after that offset the surface to 2.5 mm thickness which forms as the Class - B surface.

And then filleting the edges to 12 mm

Class - C surface

By extracting the boundary of the class - A surface, the surface required for the class - C is obtained.

using the smooth curve option a smooth surface can be obtained by sweeping the line towards the direction of the tooling axis.

Triming and joining the all the class surfaces together

Final out put:

Drafting of final surface :

using the close surface tool on the final surface

performing draft analysis on the final plastic solid model

TREE STRUCTURE:

isometric view:closed surface

conclustion:thus the switch bezel plastic component through the given class-A-surface has been created by creating class b&C and also draft analysis has been performed
