Week 9 - Challenge 1 - Base Bracket Design
BASE BRACKET:
THE OBJECTIVE OF THE BASE BRACKET DESIGN IS TO CREATE THE SURFACE AND USE THE CLOSURE SURFACE METHOD.
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 FOR THE BASE BRACKET DESIGN IS THE CLASS A SURFACE.
THE PLASTIC PRODUCT DESIGNER IS TO MAKE THE B SURFACE AND THE C SURFACE TO THE INPUT FOR THAT SOME PROCEDURE WE SHOULD FOLLOW.
STEPS THAT SHOULD BE FOLLOWED:
1. 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
HOW TO CREATE THE TOOLING AXIS?
FIRST WE SHOULD LOOK INTO THE MATERIAL IF THERE IS ANY GAP IS THERE (USING THE BOUNDARY COMMAND) AND THEN TOOK THE INTERSECTION OF THE MATERIAL. THEN MAKE A LINE ON THE ANGLED EDGES FROM WHICH WE CAN EASILY GET THE CENTER POINT
THEN MAKE THE LINE ON THE BOTH THE SLANTING EDGES THEN WE NEED TO MAKE THE BISECTION FOR THE TWO LINES THE NEW BISECTING LINE WHICH COMES AFTER THIS PROCESS IS THE TOOLING AXIS HIGHLIGHTING THE AXIS AND CHANGING ITS GRAPHIC PROPERTIES FOR BETTER VISIBILITY
(BELOW IMAGE REPRESENTS THE BISECTING METHOD)
2. THEN WE SHOULD DO THE DRAFT ANALYSIS FOR THE MATERIAL.
WHAT IS DRAFT ANALYSIS?
THE DRAFT ANALYSIS IS THE CORE THING WHEN 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 AND C SURFACE THE MUST BE SET 3 DEGREE IF THE DRAFT WOULD NOT CLEAR THEN WE ALTER THE VALUES UPTO 3 DEGREE FOR EG ( 2.8,2.9)
