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

Report

tooling axis creation

for this component, I use bisecting method. first I create a point on the extracted surface. then I use intersect command to intersect the component. I found the line then I create two lines coincident with intersecting lines.

after that use bisecting method to create a tooling axis

Draft analysis

Draft analysis is a common tool used in CAD (computer-aided design) software to determine the angles of sloped surfaces in a 3D model. The purpose of the draft analysis is to identify surfaces that do not have a uniform angle of inclination or draft angle, which can cause manufacturing and production issues in processes like injection molding, casting, or stamping.

this component has less than a 3 deg draft in some areas.

those areas have 0.9 deg draft

draft analysis for part body

Class B surface creation

offset 2.5mm

one patch is not properly offsetted

I performed Multisection over that patch

complete

A+C surface

triming

AC+B

close surface

part body

Rib creation

paded

draft 0.5deg

screw boss design

draft 0.5 deg

Uni trim RIB and Screw boss With the part body

fillet 0.25mm

perform draft analysis on complete part on screw boss side

ribs and screw boss have 0.5 deg fillet

0.4deg
