Week 9 - Attachment Feature Creation - Challenge 2
AIM:
To Create the Dog House for the Door Trim considering the design rules mentioned in the video. Consider the thickness of the part to be 2.5 mm.
"C" is where the doghouse contacts the backside of the surface
-
Doghouse wall thickness at the intersection of the part wall ( C ) should be 40% or less than the main wall stock ( T ).
-
The height of ( B ) should be between 3.0 – 6.0 mm
GIVEN CLASS A SURFACE:
CREATION OF TOOLING AXIS:
STEPS:
- Check the connectivity of the Class A Surface .Ensure that there is no gap between the component, using join command check it or by clicking boundary command.
- Find the possible tooling direction for the given component,it is the direction of mould(core or cavity) opening and closing.
- NEXT FIND THE DRAFT ANALYSIS,DRAFT IS required on all the parts in the direction of mould movement in order to allow parts to release (or) eject from the molds properly
- DRAFT NOMINAL VALUE:3 degree is the nominal value,7 degree for textured faces
- colour ranges in draft vanalysis
green-draft above 3 degree
red-below 0 degree
blue-0 to 3 degree
Draft is providing angles or tapers on the product engineering features such as ribs,screw bosses,that lie parallel to the direction of release from the mould eases part ejection.
The draft is done based on the tooling direction
CREATING TOOLING AXIS:
On the normal view of door trim with respect to tooling axis,the tooling axis should clear all the area of the component.The tooling axis
should designed in such a way.Tooling direction is the direction of mould opening and closing.In the below image orange colour line is called tooling axis

DOOR TRIM WITH TWO DOG HOUSE:
CONCLUSION:
Thus the DOOR TRIM ALONG WITH DOG HOUSE is designed ap per design guidelines by using given class A surface.
