Week 8 - Challenge 4 - Bumper

TO DESIGN A CAR BUMPER BY USING CLASS A SURFACE

AIM:

• To design a car bumper Plastic component through the given Class-A surface by creating a tooling axis and draft analysis of the given surface.

DESIGN PROCEDURE:

• To setup the class-A surface and to creating a tooling axis
• add draft angle
• To create a base surface of model
• To create a B-surface
• To create a C-surface
• To use close surface for creating a solid part model

CLASS-A SURFACE:

TOOLING AXIS:

• Tooling axis can be classified into two methods

1. direct method

• For this model, to use a line at mid-point of the base of the coin holder
• Due to perpendicular walls of the class A surface

DRAFT ANALYSIS:

• The Drafting analysis was performed on the class-A surface by using the Feature Draft Analysis command.

• Using this command, the compass was set on the main tooling axis and the Draft angle was changed to 3 degrees.

CREATING CLASS-B SURFACE:

• To offset the class-A surface along 3mm for to create a B- SURFCAE.
• Surface Gaps can be filled by using a fill tool and multi sectional tool

B-SURFACE

CREATING C- SURFACE:

• To use multiple extract tool on the class A surface
• The extract boundaries can be sweep at 90 degrees to the reference boundaries up to required length

C-SURFACE

SURFACE MODEL OF A CAR BUMPER:

SOLID MODEL OF A CAR BUMPER:

TREE SHOTS:

CONCLUSION:

• To use class-A surface and create Tooling axis, Draft analysis were performed.

• The solid component was created from the surface model.
