Week 8 - Challenge 4 - Bumper

Aim :- To design the Bumper plastic component through the given Class-A surface.

Objective :-

1. To create a proper tooling direction.
2. To perform draft analysis of the plastic component.
3. To design the Bumper plastic component by creating the B-Surface and C-Surface using the given Class-A surface.

METHODOLOGY :-
In this model we have focused on the following things:

• Tooling axis
• Draft analysis
• Class-B surface
• Class-C surface
• Making a solid model from surface.
• Following tools were used to reach the final step:
• Extract
• Un-trim
• Trim
• Extrapolate
• Offset
• Edge fillet
• Boundary
• Sweep
• Join
• Close (part design)

CLASS A SURFACE :-

TOOLING AXIS :-

• For tooling axis, we have made a point on the class A surface.
• After that we have drawn line along Y axis
• Hence we have our tooling axis.

CLASS B SURFACE :-

• Firstly we have offseted our class A surface, 3mm inside direction.

• After offseting we have some gaps which have to be filled.
• For that we have extracted the both edges and extrapolated according to the requirement.
• Then trimmed and edge fillets are given.

- The same process is followed as above for all the gaps to filled.

Hence this is our final CLASS B SURFACE.

CLASS C SURFACE :-

• For class C surface, we have to extract all the edges of class A surface.

Hence, we have our class C surface

THIS IS OUR COMBINED CLASS A and CLASS C SURFACE

OPEN BODY :-

After trimming class A, C and B surface we have our open body.

CLOSE BODY :-

We have used close surface(part design) to solidfy our part.

DRAFT ANALYSIS :-

Draft analysis is performed based on colour ranges identifying zones on the analyzed element where the deviation from the draft direction at any point, corresponds to specified values. Minimum draft angle is considered as 3 degree.

TREE STRUCTURE :-

CONCLUSION :-

Thus the Bumper plastic component has been designed using the given class-A surface.
