Week 9 - Challenge 3 - Bumper

AIM : To create the Bumper Design Plastic component through the given Class-A surface.

Objective :

• To create a tooling direction.
• To perform draft analysis for given A-Surface and prepare the final close body.
• To design the Bumper plastic component by creating the B-Surface and C-Surface using the given Class-A surface.
• Take the Thickness of the component to be 3 mm.

Introduction :

The input of the product designer is in the form of the A-class surface. The job of the product designer is to create the B and C surfaces keeping all the aspects for the mold.

Class A Surface :

• Visible surface and aesthetic look.
• Surface with textures.
• Surfaces provided by customer(OEM).
• Don't have any features like(rib, snap, bosses, etc) on class A surface.
• Class A surface is made from scanned data with different software like alias etc.
• Surfaces which are having CURVATURE CONTINUITY IS CALLED class-A.

Class B surface :

• Invisible Surfaces.
• Surface mostly don't have textures.
• Surface needs to be created according to the class-A surface.
• Having all features(Rib,boss,snap etc) in B-side surface only.
• Surfaces which is having TANGENT CONTINUITY IS CALLED class-B.

Class A Surface

TOOLING DIRECTION:

NOW CREATE THE TOOLING DIRECTION FOR CLASS A SURFACE

DRAFT ANAYLSIS

Now do a draft anaylsis

ClASS -B surface

Offset class A surface and start reparing the surface

class C surface

Create class c surface and join it with class A surface

Final Surface

Once A+C surface done trim it with B surface and use close surface command in part workbench

Conclusion : The Bumper is created with consedering all Design Methodology.
