Week 12- Final project
DEVELOPMENT OF SIDE DOOR TRIM PANNEL:
Door trim panel is creation of CAD model considering following inputs as like in OEM and tier1 companiesClass A surface is givin but after applying boundries check, it has been found there is some improvement needed to be actioned to get a closed surface. Nominal thickness is taken from the provided master sections.Based on the knowledge that has been gained by taking the Plastic Design Course by CATIA V5 I have develped Class B Surgaces, Class C Surfaces, tooling axis for every single part, also, I found a strategy to assemble the four seperate parts into one part design by creating engineering features such as Heat Stakes, Ribs, Dog Houses and Flanges.
1)ARM REST:
CLASS A SURFACE:
First I have found that Class A that been givin has open boundries
CLASS A IMPROVEMENT:
TOOLING AXIS CREATIONS:
Check the best possible tooling direction by manually adjusting the compass.By analysing it is found thathe t 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 clears the draft analysis. If not create a new tooling axis
DRAFT ANALYSIS IMPROVED CLASS A SURFACE:
Now perform the Draft analysis using the Featured Draft Analysis tool in the tools.Then after opening the draft analysis tool box ,go for the compass and place the compass alinged to tooling axis, and click on the lock symbol to lock the position. after alinging click on the surface which we want to do draft analysis,minimum draft angle given is 3 degree.it shows green colour once its finished.
CLASS B SURFACE CREATIONS:
Class-B surface means the thickness of a part it is not visible and is inside part. In other words, the Class-B surface is a surface below a certain thickness from the class-A surface. This is the surface that contains engineering aspects of a model.Create an offset surface of Cin LASS-A about 2.5mm inward direction.
Check for discontinuity and rework on the offset surface using extract, multi-extract, multi sections surfaces.Join the surfaces and ensure the final CLASS-B surface created has no gaps.
CLASS C SURFACE:
The surface that joins class-A and class-B surfaarethe s is class-C surface. Class C is often specified for interior surfaces not readily visible, surfaces that will be covered by another part when assembledCreate the sweep concerningerence to the surface and tooling axis, multi-extractingting the CLASS-A boundaryJoin the sweep surfaces by using commands like extrapolate, trmulti-sectiontion surface.Finally join all the sweep surfaces and ensure the continuity of the CLASS-C surface.

FLANGE CREATIONS:
In order to Join the Armrest body with the other bodies, I created 4 Flanges seperatly with counter holes, Flanges are different based on the engineering features will be held. Then these flanges are assembled to the main body (Armrest) by unitrim feature.Each Flange was created by extracting surface from Class C Surface aidded by Generative Surface. then I applied close surface feature to creat the flange body, Drafted by 0.5 deg, Filletted. Also it is important to mention that the counter holes were created by iso constrained, positioned sketches and then paded it and drafted before it was removed from the main flange.
