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

STEP 1: DOWNLOAD CLASS A SURFACE

STEP 2: CREATING TOOLING AXIS

• Visually check first in each direction x,y, and z axis for best tooling direction
• So y direction is the best direction for tooling axis.
• Creating a point over a flat plate and making a line in y direction.

STEP 3: CREATING B SURFACE

• Simply using the offset the class A surface by 2.5mm
• After that use extrapolate, multiple extract, multisection command to fill the gap.

STEP 4: CREATING CLASS C SURFACE

STEP 5: FINAL JOIN AND TRIM

STEP 6: CREATING RIB

• Create a sketch of the ribs for the closed body using the axis system.
• Then pad this sketch and the height is 2.5*5. Next use uniontrim with the main body, get ribs for the body.

STEP 7: CREATING SCREW BOSSES

General Guidelines for Bosses:

• Draft - 0.5 degrees on the walls of boss
• Thickness - Typically 40%* of the nominal wall at the base.
• Height to Diameter Ratio - 3:1
• Radii - 0.25mm maximum radii.
