Week 12- Final project

FINAL PROJECT

DOOR TRIM PANEL -

AIM - Creation of CAD model considering following inputs as like in OEM and tier1 companies.

1. Class A surface
2. Nominal thickness
3. Attachment strategy

SOFTWARE USED - CATIA V5

OUTPUT REQUIRED -

• Create a sketch by using Positioned sketch
• All the should be sketches should be Iso-Constrained
• Ensured Proper Tree Structure
• Geometrical sets should having a proper name based on the sketches present inside of it
• Create thickened part using master section for reference
• Create the mounting features as per design guidelines in the industry and with master sections
• Draft analysis & Tooling analysis
• Creation of parting lines and check tooling feasibility

MAJOR STEPS INVOLVE IN CONSTRUCTION OF FINAL RESULT :

[SINCE THE INPUT CLASS-A OF GIVEN DOOR TRIM PANEL CONSIST OF FOUR MAIN PARTS NAMED AS,LOWER SUBSTRATE,MAP POCKET,ARM REST,BOTTLE HOLDER,SO WE WILL BE WORKING DIFFERENTLY ON THERE CLASS-B,C CREATION,TOOLING AXIS CREATION ,DRAFT ANALYSIS ETC , FOR ALL FOUR IN SEPERATE CATPART FILE .ATLAST ALL FOUR CATPART FILE WILL GET ASSEMBLED IN ONE CATPRODUCT ASSEMBLY FILE

Procedure for Tooling axis creation

• Check the best possible tooling direction by manually adjusting the compass.
• By analysing it is found that y axis as tooling direction would clear most of the faces without any difficulties.
• Now extract any surface and create a mid-point on it.
• Then create a dummy axis creating a line on the point and direction along the y axis.
• Perform draft analysis to find whether the given axis clearing the draft analysis. If not create a new tooling axis.

ARM REST

BOTTLE HOLDER

IN ANY COMPONENT, DRAFT IS GIVEN AS TO EASE IT'S EJECTION FROM MOULD.

MIN DRAFT FOR PLASTIC COMPONENT IS - 3 DEG

FOR DOG HOUSE MIN DRAFT IS 1.5 DEG FOR OUTER WALLS & 0.5 DEG FOR INNER WALLS

FOR HEAT STAKES & LOCATORS 0.5 DEG FOR INNER & OUTER WALLS
