Week 9 - Attachment Feature Creation - Challenge 1

PART I: Rib Design

1. Iso-constrained Sketches

The above line is extruded along the direciton of tooling axis, and provided the thickness of 1mm

Draft angle

Edge Fillet of 0.25mm

In a similar way second Rib was created and spaced at 5mm

Rib Creation Report:

Rib design has has to follow the guidelines provided

1. Draft: A draft of 0.5 degree is provided on the both the sides of rib to ensure easy removal from the mold

2. Thickness: It should be 40% of the wall thickness of the component

3. Rib height: It should be five times of wall thickness of the component

4. Rib Spacing: It should follow height to width ration of 3:1, while 2:1 is preferred.

5. Minimum thickness at the Rib: It should be 0.75 mm

6. Fillet: It should be of 0.25 mm

7. Width: It should be 0.4 times of the thickness

PART II: Rib thickness analysis

A rib thickness analysis was performed by measuring all the geometric parameters and to ensure they meet the provided design guidelines.

Draft analysis report:

• The green color represents angle of surface with respect to tooling axis being greater than 3 degrees.
• The blue color represents angle between 0 and 2 degrees.
• The red color represnts angle lesser than 0 degrees. It represnets errorneous draft angle that needs to be corrected.
