Week 8 - Challenge 1 - Base Bracket Design

Challenge 1 - Base Bracket Design

OBJECTIVE

• To create base bracket plastic component from the given class- A surface.
• To create the tooling axis for the plastic component
• To perform draft analysis over the plastic component.

CLASS- A SURAFCE

TOOLING AXIS

BASE BRACKET DESIGN:

1. RIB1 AND RIB2

• Bringing in the class-A surface.
• Extracting the rib surface.
• Un-trim the extracted surface.
• Extrapolate the un-trimmed surface.
• Trim the surface as per required shape.
• Repeat step 2, 3 and 4 for the next rib surface.
• Offset the created rib surfaces for 2.5mm. ( CLASS-B SURFACE

CLASS-B SURFACE:

• Intially extracting the right side rib using extract option from Class A surface.
• Then perform Extrapolate inorder to increase the length
• Now trim the surfaces to required surfaces
• Then Offset the surface inorder to get the required thickness
• Similary create the left side rib
• Now Similarly get the slanted as well as the flat surface and offset it to desired value
• And now trim inorder to get the required surface
• Now fillet the surface to required amount

Class C Surface:

DRAFT ANALYSIS:

Limiting draft angle = 7 degrees

Draft analysis from the selected hole feature as tooling axis locations.

Drfat analysis from the CG point of the plastic component.
