Week 10 - Challenge 2- Attachment Feature Creation (Dog House)
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 houses
sktech the rectangle on b surface give the proper dimesnstion and make it one side reference line and exit from sketch and takenew body and sweep it at 1.5degree at length of 20mm
make it sthickenss surface of 2mm and give the following
outer egde fillet should be 3mm
inside egde fillet should be 1mm
inside draft should be 0.5 degree
and offset inner wall at 1mm and offset bottom reference at 4 mm and split it from main body and gove the draft at 0.5mm and finaly edge fillet it .
checking with drafting analysis
ensure the model should be2.5degree for main body and 1.5 degree for dof house outer body and 0.5 for inside body.
for that creat of one more tooling axis to paralle to inside body.
