Week 11

A-Pillar

Aim:

To create the A pillar Design with Master Section and using through the given Class-A surface.

Steps:

Given Class A:

Tooling Axis:

Considering the Ejection from the cavity of the mold after manufacturing the component, it must have a nominal 3-degree draft angle.

The tooling direction is created by considering the above factor. And hence the tooling axis is created along a plane which was created using three points from the master section.

Draft Analysis of Class A:

To make the red zones into green, positive draft side draft angle was decreased from 3 to 2.8 degrees.

CREATION OF CLASS B SURFACE:

Class B surface has been created by offsetting the Class A surface.

There were some fillet errors while creating offset. Those errors were corrected by using sweep command.

CREATION OF CLASS C SURFACE

The required outer edges of the A-Surface were extracted using Multiple Extract.

Then by using the sweep command the Class C surface was created.

Then, using extrapolate command, the edges were intersected between the surface corners, which eases the trimming operation.

Now the required portion of the C – the surface was trimmed out.

CREATION OF CLOSED SURFACE

Now the class – A and Class- C surfaces were joined together by removing the gaps in between.

Then the exact surface of the Bumper was trimmed from the above-resulted trim surface with the class-B surface.

Then, by defining the part body by using the Closed Surface command in Part Design, the component's solid body is created.
