Week 10 - Challenge 2- Attachment Feature Creation (Dog House)

DOG HOUSE

• DOG HOUSE IS AN ENGINEERING FEATURE USED IN PLASTIC TRIM DESIGN.
• DOG HOUSES ARE USED AS SUPPORTING FEATURE.

• DOG HOUSE GUIDELINES :-

1. DRAFT
2. DOGHOUSE WALLS
3. PART SURFACE
4. BOTTOM OF DOG HOUSE
5. WALL THICKNESS
6. HEIGHT AND WIDTH

• DOGHOUSE WALL THICKNESS AND SINK SAVER:-

• 'C' IS WHERE DOGHOUSE CONTACTS BACK SIDE OF SURFACE
• DOGHOUSE WALL THICKNESS AT INTERSECTION OF PART WALL(C) SHOULD BE 40%OR LESS THAN MAIN WALL STOCK(T)
• HEIGHT OF (B) SHOULD BE BETWEEN 3.0-6.0mm

• DOGHOUSE HEIGHT :-

MINIMUM HEIGHT (H) OF DOGHOUSE IS 6mm

LESS THAN 6mm CAUSEES WEAK STEEL CONDITION 3:1 RATIO OF STEEL WIDTH TO HEIGHT 2:1 IS PREFERRED.

• DOGHOUSE WIDTH :-

MINIMUM DOGHOUSE WIDTH (X) FOR DOGHOUSE IS 12mm 3:1 RATIO OF STEEL WIDTH TO HEIGHT2:1 IS PREFERRED

• DOGHOUSE DRAFT TO DIE DRAW :-

MINIMUM DRAFT (D) FOR DOGHOUSE IS 1.5 DEGREES TO DIE DRAW

IF SLIDE IS BEING CONSIDERED , THIS REQUIREMENT CAN CHANGE TO 3 DEGREES MINIMUM.

• THE ENGINEERING FEATURE :-

1. SCREW BOSS ARE MOUNTED ON THEM TO INCREASE THEIR STRENGTH AND HEIGHT .

2.LOCATOR ARE MOUNTED ON THEM TO INCREASE THEIR STRENGTH AND HEIGHT .

3. SNAP ARE MOUNTED ON THEM TO INCREASE THEIR STRENGTH AND HEIGHT .

• FOR THIS DESIGN IM USING CATIA SOFTWARE:-

ALL STEPS :-

1. FOR TOOLING AXIS :-

SELECT MASSUREE INERTIA FEATURE > SELECT BODY > SELECT CREATE GEOMETRY OPTION >SELECT CENTER GRAVITY OPTION >CLICK OK

AFTER SEE ONE POINT CREATE ON THE SURFACE.

THEN SELECT LINE OPTION AND SELECT PONT & DIRECTION AND CRATE A LINE ON THE POINT .

2. DRAFT ANALYSIS ON INPUT SURFACE :-

SOWN SOME BOUNDRYY IN RED IT IS LESS THAN 3DEG

3. AFTER SOME MODIFICATION IN INPUT SURAFCE ,AND NAME IT CLASS A SURFACE, THEN DARFT ANALYSIS ON THE SURFACE WE SHOW SURFACE FULLY GREEN .

4. CREATE B SURFACE BY OFFSET METHOD (OFFSET 2.5MM):-

5. C SURFACE :-

6. FINNAL SURACE (JOIN A_B_C SURFACE):-

7. SURFACE CONVERT IN CLOSE BODY :-

8. CLOSE BODY DRAFT ANALYSIS:-

9. CREATE SIDE CORE DIRECTION LINE FOR DOG HOUSE :-

10. DOG HOUSE :-

11. DRAFT ANALYSIS FROM MAIN TOOLING DIRECTION & SIDE COREN DIRECTION:-

12. COMPLETE DOOR TRIM DOG HOUSE BODY:-
