Week 8 - Challenge 2 - Switch Bezel Design

AIM:- To 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.

Thickness of the component to be 2.5 mm.

OBJECTIVE :-

• Screenshots of the Draft analysis report for both the given Class-A surface and the final plastic component.
• Screenshots of the solid model with the proper color code of the draft angle in various orientations (Isometric, Front, Side, and Top View).

REPORT ON DRAFT ANALYSIS:

Given Class A Surface:

STEP 1: Check the connectivity of the Class A SurfaceEnsure that there is no gap between the component, using join command.We can visually check it or by clicking boundary command.

STEP 2: Find the tooling axis of the component. The tooling axis is nothing but the mould opens or cavity opens.
Check visaully which is the best possible tooling axis.

But in this component we don't have hole,So we extract Base by extract command and by using the side walls we can sketch the dummy tooling axis.Now start doing sketch on YZ plane, By using the two side walls and close sketch.

Now select ZX plane and sketch a line with a Draft angle of 3 degree and close the sketch. Bisect the two sketchs and will get Tooling axis.

EXPLANATION ON BISECTING METHOD:-
Bisecting method is basically use to find the proper tooling axis using the dummy tooling axis. In Bisecting method, bisecting line is used which either bisect the two line or it will show error which means the two lines are parallel to each other. In order to know whether the particular surface is toolable or not we intersect the surface with the respective plane and get a sketch which consist of two lines and with the help of bisecting line option we bisect the line which creates a line at the mid point of the two lines. Like wise we create tooling clearing axis for x and y which will be used to create the main tooling axis using the bisecting line option in in the line comand.

DRAFT ANALYSIS ON Switch Bezel:-

CREATING B SURFACE:-

To start with, the top rest surface is extracted and untrimmed and extrapolated, so that can be used to trim with other surface to form the class B surface,So in the same way other surfaces are also taken, untrimmed and extracted to trim with the adjoint surfaces.Once all the adjacent surfaces are taken, they are trimmed and form into the B surface.
