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

Attachment Feature Creation (Ribs & Screw Boss) :-

To Create the Attachment Features (Ribs & Screw Boss) on A Door Handle through the given Class-A surface by creating tooling direction, the tooling axis for the given Class-A Surface should meet the requirements of the draft angle.

Ribs:

Ribs should neither be too long nor too thick, otherwise, it will increase the difficulty of injection moulding, causing problems such as voids and sink marks on the back.

BOSS-

Bosses are common structures on plastic parts in home appliances and interior and exterior of auto-mobiles, mainly for positioning and fastening.

Class A surface:

Class B Surface Creation-

To create class B surface offset the class A with proper direction and distance. Here distance is the thickness of the component. As no given thickness is provided, so we are asuming the thickness value is 3MM. Reasult after offseting-

Class C Surface Creation-

Use 'Sweep' command to create a surface that is in 90 deg. angle with class A surface. The reasulyent surface will be the class C surface.

Final Closed Surface-

Class C surface trimmed with class B surface properly and joined with class A.

Solid Body-

Using 'Closed Surface' command of Part Workbench we have to make make the body solid.

RIBS-

As per design standerds we will create a sketch where ribs are needed.
