Week 11 - Project - A pillar Design with Master Section

MAKING A-PILLAR OF A CAR FOLLOWING MASTER SECTIONS:- (THICKNESS:2.5mm)

A-PILLAR:

A-PILLARS ARE THE VERTICAL AND INCLINED STRUCTURAL SUPPORT TO THE AUTOMOTIVE BODY STRUCTURE, AND IT HELPS TO ENCLOSE THE FRONT DOORS AND FOR THE ROOF."THE RED-MARKED AREA IS THE A-PILLAR OF A CAR" AND THERE ARE TWO A-PILLARS ARE THERE IN THE CAR.

MASTER-SECTIONS:

MASTER-SECTION ARE THE SECTION THAT GUIDES FOR THE DESIGN REQUIREMENTS WHICH DECIDES THE COMPONENT PACKAGING AFTER TECHNICAL STYLING SURFACES, ALL THE DESIGN REQUIREMENTS, AND THE DESIGN INFORMATION EVERYTHING PROVIDED BY THE MASTER SECTION

FOLLOWED METHODOLOGY TO MAKE THE A-PILLAR

• INPUT (CLASS A SURFACE)
• TOOLING DIRECTION
• CLASS B SURFACE
• CLASS C SURFACE (WITH APPROPRIATE DRAFT ANGLES)
• JOINING CLASS A SURFACE AND CLASS C SURFACE
• TRIM BOTH CLASS A+C AND CLASS B
• CLOSED SURFACE COMMAND
• SIDE CORE TOOLING DIRECTION
• DOG HOUSE FOLLOWING MASTER SECTION
• DRAFT ANALYSIS.

CLASS A SURFACE:

"CLASS A SURFACE" IS THE SURFACE WE CAN SEE EASILY IN THE VEHICLE IT ONLY HAS AESTHETIC DESIGN, HERE THERE IS NO ENGINEERING FEATURE PRESENT IN CLASS A SURFACE. HERE THE INPUT IS THE CLASS A SURFACE.

THE PLASTIC PRODUCT DESIGNER IS TO MAKE THE B SURFACE AND THE C SURFACE FROM THE INPUT FOR THAT SOME PROCEDURE WE SHOULD FOLLOW.

TOOLING DIRECTION:

FIRSTLY WE SHOULD CREATE A TOOLING AXIS ( WHY MEANS? - WHEN THE MATERIAL IS MANUFACTURED USING THE INJECTION MOULDING IT SHOULD EASILY COME OUT WITHOUT ANY DEFECT IN THE MATERIAL FOR THAT HERE FIRSTLY WE CONSIDER THE TOOLING AXIS FOR THE MATERIAL TO GET THE BEST RESULT.

HERE I USED THE BISECTING METHOD TO CREATE THE TOOLING AXIS FROM THE MASTER SECTION AFTER MAKING ISOLATION OF THE LINE WHICH I EXTRACT (BECAUSE THE ADDITIONAL CREATION SHOULD NOT BE THE CHILDREN OF THE MASTER SECTIONS).

DRAFT ANALYSIS:-

THE DRAFT ANALYSIS IS THE CORE THING WHEN IT COMES TO THE MANUFACTURING PROCESS. IN MANUFACTURING 3 DEGREE DRAFT IS MAINTAINED FOR A PRODUCT TO COME EASILY WHILE MANUFACTURING.SO THE MATERIAL SHOULD BE ANALYZED WITH A DRAFT ANALYSIS FOR A BETTER RESULT

HOW TO DO DRAFT ANALYSIS?

FIRSTLY WE NEED TO CHANGE THE MATERIAL (CUSTOMIZED MATERIAL). THEN SELECT THE COMPASS OPTION THEN MOVE THE COMPASS TO ALIGN WITH THE TOOLING AXIS PROPERLY. THEN CHOOSE THE LOCK OPTION TO LOCK THE COMPASS THEN SELECT THE MATERIAL THEN THE DRAFT ANALYSIS IS CARRIED OUT WE NEED TO CHECK IT SHOULD BE CLEAR THE A SURFACE IS AND C SURFACE THE MUST BE SET 3 DEGREES IF THE DRAFT WOULD NOT CLEAR THEN WE ALTER THE VALUES UPTO 3 DEGREE FOR EG ( 2.8,2.9)

THE WHITE ARROW MARKS ARE THE AREAS WHERE I DID THE 3-DEGREE DRAFT BECAUSE BOTH THE AREA ARE PERPENDICULAR TO THE TOOLING AXIS "THE AREA WHICH IS BLUE IS NOT HAVING THE PROPER 3-DEGREE"

"DRAFT ANALYSIS ON THE DOG HOUSE ITS ALSO PERFECTLY CLEARING FROM MAIN TOOLING AXIS"

DRAFT ANALYSIS USING THE SIDE CORE AXIS IT ALSO PERFECTLY DONE.
