Week 9 - Attachment Feature Creation - Challenge 2
AIM:- CREATION OF DOG HOUSE AND SCREW BOSS ON THE COIN HOLDER COMPONENT. TO PERFORM THE DRAFT ANALYSIS ON DOG HOUSE AND SCREW BOSS AS WELL AS ON COIN HOLDER.
OBJECTIVE:-
The main objective is to create a dog house under design rules .the dog house should follow the design rules. also the creation of tooling axis and to perform the draft analysis on the whole combined component.
PROCEDURE:-
DESIGN RULES WE MUST CONSIDER IN THE BEGINNING.
1. DESIGN RULES FOR SCREW BOSS:-
- Draft -0.5 degree on walls of boss
- Thickness- typically 40% of the nominal wall at the base
- Height to diameter ratio -3:1
- Radii-0.25mm maximum radii
2. DESIGN RULE OF DOG HOUSE:-
- Dog house wall thickness at the intersection of the part wall should be 40 %or less than the main wall stock.
- The height of B should 3.0-6.0mm.
TOOLING AXIS CREATION:-
The creation of a tooling axis is necessary for this component .we will direct create a tooling axis with the help of extracted base of the coin holder then we use the intersection command to create the intersection of the coin holder.
after completing of tooling axis we would go for the CREATION OF SCREW BOSS DESIGN.
First, we will do the sketching of it in sketches and for the support, we will give the rib design also .then we will pad the screw boss with ribs .
after this, we will go to the creation of DOG HOUSE.
Then we will pad the dog house.
now we will create a tooling axis for the dog house.
then for the dog house, we will perform the draft analysis.
so to avoid the sink mark we will add the screw boss to the top of the dog house design.
to get the screw boss on the top we will use the translation command.
after this, we will perform a draft analysis of the whole component.
