Week 9 - Challenge 3 - Bumper

TITLE : TO BUILD BUMPER MODEL IN CATIA V5 AS PER PROVIDED MODEL

INTRODUCTION :-

IN THIS ASSIGNMENT WE FOCUSS ON PLASTIC DESIGN PROCESSES WHICH FOLLOW BY AUTOMOTIVE INDUSTRY. IN THIS PROJECT WE CREATE BUMPER MODEL WHICH INCLUDES CLASS A,B, AMD C SURDACE OF BUMPER, ALSO WE DO DRAFT ANALYSIS AND MAKE TOOLING AXIS FOR BUMPER. AT THE END CLOSED SURFACE AND SOLID MODEL ARE MADE.

OBJECTIVE :

1 FROM GIVEN BUMPER CLASS A SURFACE WE CREATE 3D MODEL FOR PLASTIC PRODUCTION WITH USING SURFACE COMMANDS.

2.WE CREATE CLASS B AND C FOR BUMPER AND READY CLOSE SURFACE.

3. CLOSE SURFACE MODEL MUST BE COVERTED IN TO SOLID MODEL

4. CREATE TOOLING AXIS FOR BUMPER

5. DO DRAFT ANALYSIS OF MODEL AND ANGLE MUST BE MORE THAN 3 DEGREEE.

THEORY PORTION FOR PLASTIC

STEPS FOR MAKE PLASTIC 3D MODEL

1.INSERT CLASS A SURFACE - DESIDE TOOLING AXIS (FROM THIS AXIS WE CAN SEE ALL SHAPE ON THE SURFACE AND EASY FOR MAKING )

2. AS PER THE CLASS A SURFACE WE MAKE PLAN TO PRODUCE MODEL (AS PER THE SECTION AND SHAPE WE DESIDE PLAN FOR B AND C SURFACE)

3.AFTER THAT WE CREATE B SURFACE AND C SURFACE FOR BUMPER. (THICKNESS OF BUMPER IS 3 MM)

4. AS PER THE THICKNESS, SURFACE IS MOVED TO 3MM DISTANCE AND READY B SURFACE USING BASIC COMMAND.

5.AT THE END WE JOIN CLASS A, CLASS B AND CLASS C SURFACES AND CREATE CLOSE SURFACE MODEL.

6 CLOSE SURFACE WE CONVERT IN TO THE SOLID MODEL .

7.DO DRAFT ANALYSIS OF SOLID MODEL OF BUMPER (THE DRAFT ANGLE MUST BE MORE THAN 3 DEGREE --- WE ALSO SELECT LESS THAN 3 DEGREE BUT IT MAKE DEFFICULTY FOR PRODUCTION AND COST IS INCREASE)

NOTE :- FOR FILLET - UPPER SIDE FROM THE CLASS A - (THIKNESS OF MODEL + RADIUS (CLASS A) = FILLET VALUE) EX.- 14 + 2.5 = 16.5

LOWER SIDE FROM CLASS A - (RADIUS -THIKNESS = FILLET VALUE ) EX;- 14 - 2.5 = 11.5

WE DO THIS BECAUSE WE MUST MAINTAIN DISTANCE BETWEEN CLASS A AND B SURFACE .

FINAL SOLID MODEL FOR BUMPER

CONCLUSION

OVERALL , IN THIS PROJECT WE MAKE BUMPER MODEL FROM GIVEN CLASS A SURFACE. WE SEE THAT MANY PROBLEMS ARE COME DURING MAKING CLASS B SURFACE. THE PRIMERY IS THAT FILETS ARE MADE PROBLES WHILE OFFSET SURFACE , HOWEVER WE SOLVED THEM DOING RECREATE JOIN OR SURFACE. THEN WE CREATE CLASS C AND JOIN WITH CLASS A AND B. MOREOVER CLOSE SURFACE OF BUMPER IS CONVETED INTO SOLID PART. AT THE END WE DID DRAFT ANALYSIS AND MODEL WAS PASSED.
