Week 8 - Challenge 2 - Switch Bezel Design

O DESIGN A SWITCH BEZEL BY USING CLASS A SURFACE

AIM:

• To design a switch bezel Plastic component through the given Class-A surface by creating a tooling axis and draft analysis of the given surface.

DESIGN PROCEDURE:

• To setup the class-A surface and to creating a tooling axis

• add draft angle
• To create a base surface of model
• To create a B-surface
• To create a C-surface
• To use close surface for creating a solid part model

CLASS-A SURFACE:

TOOLING AXIS:

• Tooling axis can be classified into two methods

1. direct method
2. bisecting method:

• In this model we use bisect method based on the requirement. This method is used for complex components.
• To use AXIS for creating line on zx-plane and zy- plane respective to origins
• To bisect the two lines and create a tooling axis.

DRAFT ANALYSIS:

• The Drafting analysis was performed on the class-A surface by using the Feature Draft Analysis command.
• Using this command, the compass was set on the main tooling axis and the Draft angle was changed to 3 degrees.

CREATING CLASS-B SURFACE:

1.BEZEL REST SURFACE:

• To create a bezel rest surface by extract the surface from the class-A surface.
• After extraction to untrim the surface

• To offset the SURFACE down to 2.5 mm

2. WALLS:

• To create a side wall by extract the class A side faces
• To untrim the extracted side walls
• To extrapolate them for make sure to pass through all together for merge
• To trim the unwanted faces from walls by trim
• To offset the walls up to 2.5 mm

3. BASE:

• To create a base by extract the base from class A
• To untrim and extrapolate the base for final trim to create a B-surface

BEFORE FINAL TRIM OF CLASS B SURFACE:

B-SURFACE:

B-SURFACE

CREATING C- SURFACE:

• To use multiple extract tool on the class A surface
• The extract boundaries can be sweep along the tooling axis up to required length
• To replace the multiple boundaries into smooth curve for good transition
• To extrapolate and trim them for creating C-SURFACE

C-SURFACE

SURFACE MODEL OF A SWITCH BEZEL:

SOLID MODEL OF A SWITCH BEZEL:

TREE SHOTS:

CONCLUSION:

• To use class-A surface and create Tooling axis, Draft analysis were performed.

• The solid component was created from the surface model.
