Week 8 - Challenge 4 - Bumper

Aim:

Create the Bumper Plastic component through the given Class-A surface and performing a draft analysis for the completed model.

Procedure:

• Check whether the given class A surface is joined and there is no discontinuity.
• Use join or boundary command for this if there is.

TOOLING AXIS :

• Check for a suitable tooling direction in our case , normal to x-axis is the tooling direction.

Draft Analysis on a Class A Surface

• The green surfaces will be having a draft angle of more than 3 degrees .It can clear the draft anlysis.
• The red surfaces are having draft angle more than 0 degrees and less than 3 degrees.
• The blue surfaces are having negative draft angle.

Class B Surface

The class A surface is offseted to 3 mm and the necessary surface corrections are done.

Class C Surface:

The class C surfaces are created by sweep option and finaaly joined to the class A surface.

Final trim is performed to join the class A , Class B and Class C surfaces to form the closed model.

Draft Analysis of Solid Part

• The green surfaces are having draft angle of more than 3 degrees and they can clear the tooling direction.
• The red surfaces are having draft angle more than 0 degrees and less than 3 degrees.
• We can clearly see that the solid model surfaces are properly drafted.
