Week 9 - Challenge 3 - Bumper
BUMPER:
THE OBJECTIVE OF THE BUMPER DESIGN IS TO CREATE THE SURFACE USING 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 BUMPER 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 LOOK DOWN INTO THE THREE DIRECTIONS (X,Y,Z) FOR A BETTER OUTCOME FOR THE PRODUCT WHILE MANUFACTURING. WHILE LOOKING THE VIEW THE ENTIRE PORTION CAN EASILY BE VISIBLE WHEN CHOOSING A DIRECTION.
2.THEN 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 DEGREES IF THE DRAFT WOULD NOT CLEAR THEN WE ALTER THE VALUES UPTO 3 DEGREE FOR EG ( 2.8,2.9)
