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

AIM:

• Create the Rib and Screwboss for the Drill Handle considering the design rules.

Tooling Axis:

• The direction in which the mould open and closes is called the tooling axis direction.
• Here, using project intersection along xy plane is created and the two inclined lines were drawn inside the positioned sketch.
• Then bisecting lines with the two inclined lines were drawn.
• Thus, the tooling axis is drawn.

Class A surface:

• After receiving the clasa A surface check the connectivity of the surface using join or by boundary.
• If it is not join together make it with a minimum tolerance of 0.001 to 0.003 and check for connectivity of the surface.

Class B surface:

• Class B surface is created by offesting the Class A surface for 2.5mm (according to the thickness).
• The patches which are formed after offesting are closed using commands like extract ,extrapolate, multisections and trim.

Class C surface:

• For Class C surface the outer boundary of the Class A surface is taken and using the sweep command with both reference to surface and draft direction Class C surface is created.

Final Solid Component:

Ribs:

• Ribs are a feature in plastic injection molded parts. They are thin extensions that run perpendicular from a wall or plane. They are commonly used to provide additional support and strength to a part.

SCREW BOSS DESIGN:

• Bosses are projections designed to accept inserts, self-tapping screws, etc. for use in mounting, fastening or assembling parts.
