Week 9 - Challenge 1 - Base Bracket Design

TITLE : TO CREATE PLASTIC PRODUCT IN CATIA V5 AS PER THE GIVEN CLASS À SURFACE (BASE BRACKET )

INTRODUCTION :-

IN THIS ASSIGNMENT WE FOCUSS ON PLASTIC DESIGN PROCESSES WHICH FOLLOW BY AUTOMOTIVE INDUSTRY. WE HAVE BASE BRACKET SURFACE WHICH GIVEN BY THE INSTITUTE AND THE BRACKET SURFACE WE WILL CONVERT IN THE 3D PLASTIC MODEL WHICH HELP FOR PRODUCTION. WE USE SURFACE METHOD TO MAKE PLASTIC 3D MODEL. WE ANALYSE TOOLING AXIS AND DRAFT ANGLE.

OBJECTIVE :

1 AS PER THE GIVEN CLASS A SURFACE OF BASE BRACKET WE CREATE 3D MODEL FOR PLASTIC PRODUCTION WITH USING SURFACE COMMANDS

2. SURFACE MODEL MUST BE COVERTED IN TO SOLID MODEL

3. CREATE TOOLING AXIS FOR BASE BRACKET

4. DO DRAFT ANALYSIS OF CLASS A SURFACE OF BASE BRACKET

THEORY PORTION FOR PLASTIC

STEPS FOR MAKE PLASTIC 3D MODEL

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

- DO DRAFT ANALYSIS OF CLASS A SUFACE (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)

- AS PER THE CLASS A SURFACE WE MAKE PLAN TO PRODUCE MODEL (AS PER THE SECTION AND SHAPE WE DESIDE PLAN OF MODEL)

- AFTER THAT WE EXTRECT SURFACE- UNTRIM SURFACE- DO OFFSET AS PER THE THIKNESS (2.5MM) --- B SURFACE

- C SURFACE - IT SHOW THIKNESS OF PART SUCH AS 2.5MM FOR BASE BRACKET

- AT THE END WE JOIN CLASS A, CLASS B AND CLASS C SURFACES

- CLOSE SURFACE WE CONVERT IN TO THE SOLID MODEL

NOTE :- FOR FILLET - UPPER SIDE FROM THE CLASS A - (THIKNESS - RADIUS = FILLET VALUE) EX.- 3 - 2.5 = 0.5

LOWER SIDE FROM CLASS A - (RADIUS + THIKNESS = FILLET VALUE ) EX;- 3 + 2.5 = 5.5

CONCLUSION

OVERALL , WE HAVE SEEN HOW TO MAKE 3D MODEL FOR PLASTIC PRODUCT. WE MADE BASE BRACKET USING SURFACE COMMAND IN CATIA V5 AND CREATE TOOLING AXIS AND DRAFT ANALYSIS.
