Week 9 - Attachment Feature Creation - Challenge 1

RIB DESIGN

Objective: The objective of this challenge is to create a Rib Design on the console coin holder with draft analysis and apply proper design rules for the Rib.

Define: Rib provides a means of economical stiffness and strength without increasing overall wall thickness. The rib is the B-side feature creation.

• It is locating and arresting components of the assembly.
• It provides alignment in mating parts.
• acting as stops or guides for machines.

General Guidance for the Rib design:

1. Height: 5 times the component thickness
2. Thickness: 0.4 times the component thickness
3. Draft angle: It must be 0.5 deg
4. Spacing between two ribs: Y/x =>3
5. Thickness at Tip:0.75 time of component thickness
6. Optimal Radius: 0.25 time of component thickness
7. Design suggestion:

1. Height of the Rib: It must be 5 times the component thickness. The thickness of the component is 2.5 and it multiplies by five (5x2.5=12.50).

2. Thickness of the Rib: Thickness: 0.4 times the component thickness (0.4x2.5=1).

3. Draft angle: It must be 0.5 deg

4. Spacing between two ribs: Y/x =>3

5. Thickness at Tip:0.75 mm at least.

6. Optimal Radius: 0.25 time of component thickness

Design suggestion:

Draft analysis: Now we check the draft analysis for ribs and the component we have a draft angle of 0.5 for the ribs so we took the 0.48-degree draft angle for the analysis.
