AIM:--

Create the Bumper 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 to be 3 mm

To be able to create solid from the given Class-A surface, by considering tooling axis and draft analysis.

The given Class-A surface:--

WHAT IS CLASS A SURFACE ?

It is an Asthetic surface and which is visible to the customers ie, Top surface,

Tooling Axis:--

~ The tooling axis is the tool movement axis (core/cavity).

~ This axis will decide the draft direction.

FIG:--EXTRACEDTHE SURFACE AND CREATED THE POINT AND CREATED THE TOOLING AXIS LINE.

FIG:-- TOOLING AXIS

Performing draft analysis on the given Class A Surface:--

FIG:--The draft is considered as 3 degrees.

THE CTREATION OF CLASS B SURFACE :--

WHAT IS CLASS B SURFACE ?

The surface which is thicken and applying the engineering features in it that sorface is called as CLASS B SURFACE

NOW OFFSET THE CLASS A SURFACE FOR 3mm IN INWARD DIRECTION.

FIG:--THERE WILL BE GAPS IN THE FILLET AREAS AND USE MULTIPLE EXTRACT COMMAND AND SELECT THE SURFACE AND EXTRAPOLATE IT AND TRIM AND USE EDGE FILLET

FIG:-- CLASS B SURFACE.

THE CREATION OF CLASS C SURFACE:--

WHAT IS CLASS C SURFACE ?

The surface which joins the class A and B together that surface is called as CLASS C SURFACE .

By using the MULTIPLE EXTRACT Command create a boundary and use SMOOTH CURVE Option to smooth the curve and use Sweep command to create a surface along "WITH REFRENCE SURFACE".

And the angle of draft given in Sweep is 90Degrees.
