Week 10 - Challenge 3 - Door Trim Lower with Engineering Features

1)

First we need to creat real tooling axis, for that we have to intersect the surface A in x and y axis then we got two dummy axis then we have to bisect the two lines in order to get the real tooling axis of surface .

1st we extract the bottom base because we can easily creat the tooling axis in z direction , then creat point on base surface and go for position sketch and select zx and zy plane for creating the dummy aixis

but in this complex model its very difficulty to vislble all parts in one axis. here we choose x axis because we can able to see more parts compare to other axis.

here, we set one point on appropriate edge for creating the tooling axis and creat line .

class b surface

offset the surface into2.5mm towords to inside and extract the non connectivity parts from main body

creat of class c surface

surface which has perpendicular to drafting axis then we have to go for drafting with tooling axis and gives 3 degree draft towards to outside

suppose surface which has parrallel to drafting axis then we go for reference with surface option and gives 90 degree for sweeep.

join A and C surface

finally trim the class B with join A and C surface

make it closed solid surface using closed surface

creation of dog heat stakes and locators

locator

take the dimension of 15mm for each side and thicken it 2mm

draft should be 0.5mm

edge fillet should be 0.3mm

chamfer should be 3mm

and translate parent one into opposite side using translation

and creat the two way locator in middle position of fourway locator

heat stakes

take the hole of 5mm and 0.4*T for each side for outer dia

creat one heat stake and copy the parent and tranlate it into 15 point respectively using point point translate

all three locator height should be same and heat stakes height should be less than loctor.

drafting analysis

main parts are 3degree

heat stakes and locotor should be 0.5degree
