Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1

AIM:

• To analyse the given class A surface with feature draft analysis.
• To create tooling axis and create Class B and C surface and form part body.
• To create ribs and screw bosses of the given class A surface.

Tooling axis:

• A centre point is formed as reference point on base surface
• From the reference point,axis system is formed.
• Tooling axis by bisection method:
  • From the tooling axis line XZ & YZ plane,an axis line is created by bisecting the two tooling axis line.

Draft analysis:

• From the feature draft analysis,3 degree drafting angle is good in most of the surfaces.
• Only few areas of surfaces are near to zero degree drafting angle.
• Reducing drafting angle to 0.5 degree all areas are getting cleared.

DOOR HANDLE

As per design rules, ribs has to be formed in the distance twice of thickness of the component.Here, two ribs are formed as shown in the challenge.
