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
- direct method
- 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
- 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
- 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.
