Week 8 - Challenge 2 - Switch Bezel Design

Aim: Create the Switch Bezel Plastic component through the given Class-A surface.

Objectives:

* To create class B & C surface for the given component.

* To form the tooling axis and capture the surface properly.

* To check the feasibility of the component with a draft of 3 degrees.

Method: In order to obtain the proper draft analysis tooling axis is required and the following steps show how it is done.

* As this component has 1 hole from where the tooling axis can be generated, however it does not have proper 4 walls to generate it. In this case, an approximation is made in order to obtain the tooling axis.

* First by using the two side walls a dummy axis is made. As it is known that the draft angle is 3 degrees, the second axis is taken as a to the given wall and using these two axis the tooling axis is made.

TOOLING AXIS

* It is nothing but the direction in which the mold opens and closes the draft angle needed to be provided by considering this tooling axis.

* We can create a tooling axis by using the bisecting method.

CLASS B SURFACE

CLASS C SURFACE

* After forming the class b & C all the three surfaces can be trimmed and check for any discontinuity.

* Sweep angle is 3 degree .

* After trimming, this is how the surface will look like.

* Solid formed after the class A,B & C surface.

DRAFT ANALYSIS

*The above image shows the draft analysis in which green color surfaces shows that they are having an angle of more than 3 degrees but the surface in red color shows it is less than 3 degree that is having an angle of 2.22 degrees. These are the results of the draft analysis which are very crucial for determining the feasibility of the product.

* +ve draft is Green

-ve draft is Blue

No draft is Red
