Week 8 - Challenge 2 - Switch Bezel Design

TTom Thankachan11 Feb 2023

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.

Take the Thickness of the component as 2.5 mm

Given Class A Surface:

Make sure there is no gaps in between surfaces,visually we can check it or by clicking boundary command.
Find the tooling axis of the component. The tooling axis is nothing but the mould opens or cavity opens.
Look for the best possible tooling axis according to the product shape
Check all three axis, Along x and y it is not faesible.so z is the best possible tooling axis.

Tooling axis

To create tooling axis take intersction lines from the surface in X and Y direction,use bisecting lines option to get main tooling axis as below

Creating Class B Surface:

Before creatin B surface,make an extract copy of given Class A surface,extracting the surface by using extract option from Class A surface,then do untrim for the extracted surfaces, Then perform Extrapolate inorder to increase the length,make sure select point continuity while doing extrapolate.

Then trim the extra surfaces to get required surface.

Then do Offset the surface to a distance of 2.5 mm inorder to get the required thickness, Now Similarly do the same to all surfaces

Now apply fillet to required areas according to class A surface consider thickness value to the radius always(radius+thikcness of the part 2.5 mm)

Class C Surface

Class C surface is made by extruding edges of class A through class B surface by swept tool,the do the trimming operation to remove unwanted surfaces.
