Week 9 - Project - Master Section Development

AIM:- TO CREATE B-PILLAR MASTER SECTION.

OBJECTIVE:- TO CREATE A B PILLAR WITH THE HELP OF THE MASTER SECTION. IN THIS WE CREATE CLASS A, CLASS B, CLASS C SURFACE AND CLOSED CAD PART OF THE B -PILLAR. WE WILL ALSO ADD B-SIDE FEATURES TO IT. AND ALSO PERFORM THE DRAFT ANALYSIS FOR THE WHOLE CAD PART.

A GENERAL IDEA ABOUT THE B-PILLAR.

METHODOLOGY:-

FIRST WE WILL LOOK FOR THE BEST WAY TO CREATE A TOOLING AXIS. TOOLLINNG AXIS IS THE DIRECTION IN WHICH THE CORE AND CAVITY MOVE. FOR THE TOOLING AXIS WE WILL USE THE MASTER SECTION. WITH THE HELP OF THE MASTER SECTION WE CAN EXTRACT IT AND CREATE 4 PARTS. NOW WITH THE HELP OF THE BI-SECTION METHOD, WE WILL CREATE A LINE THAT WILL BE IN Y-DIRECTION.

AFTER CREATING THE TOOLING AXIS WE WILL GO FOR THE CREATION OF CLASS A SURFACE.

A-CLASS SURFACES ARE THOSE AESTHETIC/ FREE FORM SURFACES, WHICH ARE VISIBLE TO US (INTERIOR/EXTERIOR), HAVING AN OPTIMAL AESTHETIC SHAPE AND HIGH SURFACE QUALITY. FOR CLASS A WE WILL CHECK THE CONNECTIVITY OF THE WHOLE CAD SURFACE. IF THERE IS ANY GAP THEN WE WILL USE THE SURFACE FEATURE TO CREATE IT . THE CLASS A WILL LOOK LIKE THIS.

CLASS B CREATION

GENERALLY, CLASS B IS THE CANT BE SEEN BECAUSE IT IS HIDDEN BENEATH THE CLASS A SURFACE. IT IS BASICALLY THE OFFSET PART OF THE CLASS A SURFACE.

THEN WE WILL GO FOR FLANGE CREATION BY USING THE SWEEP COMMAND. FLANGE MUST BE PERPENDICULAR TO THE CLASS A SURFACE.

THE C SURFACE CREATION

THIS SURFACE CAN ONLY BE CREATED PERPEDICULAR TO CLASS A SURFACE BY USING SWEEP COMMAND.IT IS GENERALLY HIDDEN IN BACK SIDE .

TRIMMED PART OF A AND C.

CREATION OF CLOSED SURFACE.

B SIDE FEATURES AND THEIR DESIGN RULES.

THESE ARE THE FEATURES THAT PROVIDE SUFFICIENT STRENGTH TO THE PLASTIC COMPONENT. GENERALLY LOCATED AT THE BACKSIDE OF THE CAD MODEL.

THESE FEATURES ARE RIBS, A 4 WAY LOCATOR, A 2 WAY LOCATOR, AND DOGHOUSE BUT CURRENTLY, WE WILL WORK ON A DOG HOUSE,4 WAY LOACTORAND RIB DESIGN.

CREATION OF DOG HOUSE

WITH THE GIVEN MASTER SECTION WE WILL CREATE THE DOG HOUSE AS THE MASTER SECTION IS NOT ACCURATE WE WILL MODIFY OUR DOGHOUSE.

SKETCH OF DOGHOUSE.

CREATION OF SKETCH INTO SURFACE.

THEN WE WILL CONVERT THIS SURFACE INTO A CLOSED SURFACE.

NOW THE CREATION OF 4 WAY LOCATOR.

RIBS

RIBS ARE GENERALLY DISTRIBUTED EQUALLY AT THE BACKSIDE OF THE PLASTIC COMPONENT.
