Challenge

Week 12- Final project

AIM :- To create a CAD model for door trim panel's parts by considering the given inputs of class A surface along with master section by following the design rules followed in OEM and tier1 companies.

Objectives :-

  • To create individual tooling axis for the parts and perform draft analysis on the class A surface
  • To create the class B and class C surfaces from the given class A surface
  • To form a solid geometry by combining all the surfaces
  • To decide an attachment strategy for the part and create engineering features in reference from the master section provided
  • To perform draft analysis on the solid part model with all engineering features
  • To assemble all the components togehter to obtain the final trim

Given Data :-

  • Class A Surface for Door Trim Panel -

As we know in automotive industry there are complex products that we have to design but this is not possible with simple sketches for that we need Class A Surface.

The A-surface or the styling surface is first checked for any gaps and other issues in its surfaces. This Surface acts as the input surface so any correction to be done should be with approval from the styling team or done by them. A- perfect surface is the one when a boundary is created, the lines are only on the edges of a component and its holes or cutouts as shown below.

CLASS A SURFACE OF ARM REST:-

IMPROVEMENT OF CLASS A:-

  • Creation of Class B Surface -

Class B surface is created by offseting class A surafce by 2.5 mm as per the mastersection. After offseting some area not get offseted , there patches formed. This patches are closed by surface creation features such as fill , multisection , blend etc.

  • Creation of Class C surface -

C surface is the connecting surface of Class A and Class B surface. By using Sweep we created the Class C surface. For that first we have to extract Class A boundary and then with draft direction at angle 3 degree we have sweep the class A extracted boundary. And we get the Class - C surface.

  • Creation of Closed Body of Arm Rest - By trimming join of Class A ,C with Class B surface we get close body.

CLOSED BODY:-

  • Creation of Flanges on Arm Rest -

From mastersection we get the idea of flanges . I have created flanges on Arm Rest by considering counterpart (Lower Substrate) position.
