Week 9 - Attachment Feature Creation - Challenge 2
Aim: To design plastic screw Boss and Dog House on existing coin Holder model.
Design consideration for screw Boss
- Draft – 0.5 degrees on walls of boss
- Thickness – Typically 40% of the nominal wall at the base.
- Height to diameter ratio – 3:1
- Radii – 0.25mm maximum radii
Design consideration for Doghouse
- Doghouse wall thickness at the intersection of the part wall (c) should be 40% or less than the main wall stock (T)
- Height of (B) should be between 3.0 – 6.0 mm
Draft Analysis:
Draft analysis enables you to detect the part we drafted will be easily removed. This type of analysis performed on the base of color ranges identifying the zones on the analyzed element where the deviation from the draft direction at any points, corresponds to specified values.
- Go to insert
- Click on the compass icon and align it with the tooling axis and click on the surface, we will get our result.
Main Tooling Axis
Side Tooling Axis
Conclusion:
In this way i have successfully Design screw boss and dog house by following all the design consideration.
