Week 9 - Challenge 2 - Switch Bezel Design

AIM:Create the Switch Bezel Plastic component through the given Class-A surface and perform the draft analysis.

OBJECTIVE:

1. Ensure Proper Tree Structure.
2. Geometrical sets should have a proper name based on the sketches present inside them.
3. All the sketches should be created under the Geometrical set.
4. Use the Close Surface feature to make a solid body from the surface.
5. To publish the Tooling Axis, Class A, B, and C surface.

• CLASS A SURFACE

TOOLING AXIS:

Tooling directions created by bisecting method.The ejection from the mold after manufacturing the interior trim must have the nominal 3 degree draft angle.

The base surface of the class-A was extracted to create a reference point on the surface using the point, create a line in the z-direction and an axis system was inserted to the point .Then using projection intersection along the yz plane is created and the two inclined lines were drawn inside the positioned sketch. So the bisecting lines with the two inclined lines were created.

Then the same procedure is done along the xz plane but on xz plane, we only have one surface line so the center point is used to extrude a line along the z-direction and gave a measurement of 6 degrees. from the surface line.

Bisecting these two lines sketch1 and sketch2 the bisecting line is created and published as a tooling axis

• CLASS B SURFACE

For the creation of Class B, class-A surface divide into 3 different surfaces.

B Surface creation include

1. Extract
2. surfaces untrim
3. Extrapolate the surfaces
4. Offset the surfaces by 3 mm
5. Trim

CLASS B SURFACE

• CLASS C SURFACE

The edges of the Class-A surface are extracted using the multiple extracts and then converted into smooth curvature to avoid the patches.

Sweep operation is performed (with draft direction) selecting the smooth curves as the guide curve and tooling axis as the direction and draft angle as 3deg.

FINAL TRIMS:

Join CLASS A and CLASS B.There is some unwanted boundary, extrapolate class-A by a small distance and trim it with class-c instead of joining them.

Then trim the class-C surface with the class-B surface.

• Go to the part workbench by using the Close Surface feature we created a solid body from the surface.

• FINAL DESIGN

SWITCH BEZEL

DRAFT ANALYSIS:

The draft analysis command enables you to detect if the part you drafted will be easily remove.

Change the part into material mode and In the draft analysis command, place the compus on tooling axis to create the Draft Analysis.

RESULT: Switch Bezel plastic component using class-A surface successfully created and performed the draft analysis on the final plastic component.
