Week 8 - Challenge 3 - Switch Bezel Design
Switch Bezel Design
The objective of this project is to Create the Switch bezel Plastic component through the given Class-A surface.Along with the Tooling axis and the Draft analysis on the component.
INTRODUCTION
The Draft Analysis command enables you to detect if the part you drafted will be easily removed. This type of analysis is performed based on colour ranges identifying zones on the analyzed element where the deviation from the draft direction at any point, corresponds to specified values.
Tooling direction is the main consideration for plastic part and mould parts because it defines the movement of the mould part and the possibility of the plastic part coming out from the mould part (Core and Cavity).

TOOLING DIRECTION
The Tooling Direction is basically the direction that the mold pulls apart. The mold is built in two separate pieces, basically. You have a Cavity side and you have the Core side. The Core pulls apart from the Cavity and that's the Dyeline or the Tooling Direction.
PROCEDURE FOR CREATING TOOLING AXIS
Firstly import the given class A surface to the catia.
- Check For any defects in the surface such as boundries and estimate the possible tooling direction

Create an intersection curve between Class A and X-axis and create a bisecting line between the lines of draft surface

Create Y axis clearance with an angle to the draft surface

Create the actual Tooling axis by bisecting X and Y axis clearance lines

Draft Analysis
Using the feature draft analysis, perform draft analysis on the surface considering the tooling axis
3 degrees draft is optimum for the plastic moulding component

Creating B surface
To create the B surface offset the parts of class A surface without fillets



Trim the surfaces to create B surface

Creating C surface
To create C surface Create sweep with draft angle of 3deg w.r.t tooling axis from the boundry of class A surface
Finally trim A,B,C surfaces to create SWITCH BEZEL surface component

Use the feature closed surface to create part body from the surface

Perform draft analysis on the part body
