Week 8 - Challenge 2 - Switch Bezel Design

Week 8 - Challenge 2 - Switch Bezel Design

AIM:- Create the Switch Bezel Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model. 

Tooling Axis Creation

Using the two side walls 1st axis is made by bisecting  the side wall axis

As the 4th wall is not there, an assumption is made and the axis is taken which is 4 degrees from the horizontal axis.

Using the above two axis that we created  are bisected to create a tooling axis .The red color line is tooling axis

Class A surface

Class B surface 

creation of class B surface step by step 

First using the Extract command the surface is extrated from class a and untrimed  and exploded and then it is offseted ta a thickness of 2.5mm to create above surface 

 then the side surfaces are extracted from class a  and untrimed and exploded and then trimed and then offseted at 2.5mm

Then both the trimed together 

then fillet is given to form  above final class B surface 

Class C surface

Creation of class c surface step by step

It is created by multi extracting the boundary of class A surface and then making it smooth by spline and then sweeping it ( angle 3 degree)  and extracting  the edges and then triming it  to created B surface 

Creation of Trim of AC

final surface element 

The trim Ac  are trim with B surafe to create above final surface 

The final component is made using close surface command  and the thickness of the component is 2.5mm as given in the challenge 

Draft Analysis of class A surface 

1.1 Draft Analysis of class A surface with  draft angle 3mm with red patches and uneveness

1.2 Draft analysis of  final class A surface (Updated final Class A surface without uneven red patches) draft angle 2.7

Draft Analysis of final  plastic component 

1.1 Draft Analysis of final  plastic component with  draft angle 3mm with red patches and uneveness

1.2 Draft analysis of  (Updated  final  plastic component without uneven red patches) draft angle 2.7
