Week 8 - Challenge 4 - Bumper

AIM :

To create a body of Bumper from the input given which was the A-surface of a Bumper. The created body should be a closed solid volume which should be feasible for manufacturing and Tooling. The draft angle and draft analysis of the component should be done.

In model, proper tree structure to be maintained and publications of Tooling axis,A,B and C surfaces to be done.

INPUT GIVEN:

• A-Surface

• Thickness of component is 3.00mm

• Draft angle is 3 degrees.

CHECKING THE INPUT - A SURFACE:

The A-surface or the styling surface is first checked for any gaps and other issues in its surfaces. This Surface acts as the input surface so any correction to be done should be with approval from the styling team or done by them. A- perfect surface is the one when a boundary is created, the lines are only on the edges of a component and its holes or cutouts as shown below.

CREATION OF TOOLING AXIS:

Viewing from X axis the tooling can be cleared from this direction tooling axis can be created by line command

DRAFT ANALYSIS ON A SURFACE

CREATION OF B-SURFACE :

The A-surface is offsetted by 3.00mm as it is the thickness required.

The offset surface is the B-surface but had some issues like in some areas shown in below images.

The Areas where the B-surface has issues are corrected by closing them using commands like Multi section,Sweep,Offset and extract.

Finally all the created surfaces are trimmed or joined together with offset surfaces done earlier. This created a single single surface which will act as the final B-surface.

CREATION OF C-SURFACE :

The A and B surfaces are connected by another single surface which is called the C surface.

It is created by using sweep with A surface acting as the reference surface and curve created from the boundary of the same surface.

Sweep with draft direction is also used to create A surface

CREATION OF CLOSED BODY :

All the surfaces (A,B,C) are joined together to form a closed body.

Boundary is selected and the body is picked. Since an error popped up it can be understood that all surfaces are joined with each other to form a proper closed surface body.

Finally in part design workbench, using close volume it is changed to a solid body.
