Week 11 - Final project

Aim :

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

1. a) Class A surface
2. b) Nominal thickness : Refer master sections
3. c) Attachment strategy :

Find a attachment strategy for the door panel complete work.

Use Push pin with Dog house for Lower substrate – Door panel attachment

Use heat stakes for part to part attachment

Solution:

We will create solid body for the following Class A surface :

We have created an assembly and separated the lower substrate as shown below:

Creation of B Surface:

We have offsetted the class a surface by 2.5 mm as shown below :

Creation of Class C Surface:

Using blend command we get the following c surface using the same for the whole class a suface we get :

We have joined the Class A ,Class B and Class C surface.

Creating Solid Body we get the following :

2.Part 2 :

We have the following class A surface as shown below :

Creation of Class B Surface :

We have created class B surface as shown .

Creation of Class C Surface :

We have created c surface using blend we get the following :

Now in order to get a solid body we will split this body as shown below :

The second half is as shown below:

We will use the same method of creating the class b and class c and after that joining it with class a surface as shown below:

Part 3 :

We have the following the class A given:

Creation of Class B :

We have created the following as class b surface:

Creation of Class C Surface:

We have created the following class c surface.

Now we will join all surfaces.

We have created the solid body as shown :

Part 4 :

We have the following as class A surface as shown :

Creation of Class B Surface :

We have offsetted the class A surface by 2.5 mm as shown below :

'

Creation of Class C Surface :

We have created the class c surface using blend command as shown below :

Final Join :

Now we will be joining the class A ,Class B and class C as shown :

Now we will create the solid body as shown :

Now we have body with a thickness of 2.5 mm as shown below :

Joining Features:

The lower substrate is joined with the map pocket with the following flanges as shown:

We have created the flanges as shown below :

Now we will create the heat stakes as shown below on the lower substrate :

Creation of Doghouse :

Now we have created the doghouse as shown below :

They have the pushpin attached to it .

Now we have attached the following part with the lower substrate with upper pocket as shown :

We have also attached the upper pocket with the same method as shown below :

Therefore all part are joined by heatstakes and doghouses as shown below in the final product :
