Week 9 - Attachment Feature Creation - Challenge 1

AIM:Create the rib for the Centre console coin holder considering the design rules\

PROCEDURES:

Open the coin holder body into surface workbench
insert new geomatrical set for tooling axis and create tooling direction
for creating tooling direction extract the base plane and make a line on y direction and make it as tooling direction
then we want to create rib on outside of coinholder
create a postion sketch and a draw a line with proper constrains

Make sketch into output feature
then extrude it into tooling direction axis
from here we want to consider design rules for ribs
go to part workbench and thicken the surface
thickness must be wall thickness * 0.4 = 2.5*0.4=1
hight of rib must be 5 times of thockness =2.5*5=12.5
after assign proper thickness we want join rib into coinholder
therefore we want use boolian opperation here and assumble into coinholder body
then we need to create draft angle for rib
go to draft option and select all sides and select tooling axis and profile and set draft angle is 0.5 (optional draft angle)
then provide edge fillet of 0.25mm radius
after ctreating rib we want to interect the surface and need to extract the boundary for checking rib root thickness
Ribs create thick sections at the root (defined by the circle below). This area is thicker than the nominal wall thickness and susceptible to sink.
Rib root thickness should not be more than 25% greater than the wall thickness.
for that creat a trigent circle in fillet area and check for its diameter and analyse differnts from wall thickness

here dia is 2.670 and wall thickness is 2.5 , yes rib root thickness is 25% greaterthen wall thickness
after this we want to create second rib
create a new sketch from refrance of sketch 1 and constrain it properly
follow similer sketch we followed in rib one
and check distance between rib
distance between rib must statisfy 3:1 ratio of hight and wall thickness
so it is is approx 5 mm
