Week 9 - Attachment Feature Creation - Challenge 2

Challenge: Create the Dog House for the Door Trim considering the design rules mentioned in the video. Consider the thickness of the part to be 2.5 mm.

Inputs:

1.Class-A Surface

2.Thickness of the component

Class-A Surface

To ensure the connectivity between the surfaces, all surfaces joined using join command.

With this it is concluded that all surfaces are joined properly & there are no gaps between the surfaces.

Using boundary command Class-A surface checked for unnecessary open profiles between the surfaces.

Tooling Axis

To create a tooling axis few steps need to be followed

Step 1:

a. Create a point at Centre of Gravity (CG) of the surface

b. Follow the instructions to create a point at CG

Go to Measure tool bar

Measure --> Measure inertia --> Create Geometry --> Non-associative geometry --> Centre of Gravity --> Ok --> OK.

CG point created for the given Class-A surface.

Tooling direction checked for X,Y&Z axis. Tooling can clear all the surfaces in Y-direction.

Tooling Axis created along Y-axis using the CG point.

Draft Analysis on Class-A surface

Few steps need to be followed to perform draft analysis.

a. View --> Customise view parameters --> Mesh --> Material --> Ok.

b. The go to Insert --> Analysis --> Feature Draft Analysis

c. Click on compass from the direction, drag & drop compass on the tooling axis in such a way that Z axis to be along the tooling axis.

d. Lock the compass using lock command from direction.

e. Click on the surface to see the results.

Draft Analysis on Dog House in Tooling in X-direction.

Class-B surface creation

Class-A surface is off-set by thickness.

Gaps were filled using Fill command.

Claa-B surface.

Class-C surface Creation

Class-C surfaces created using the boundary of Class-A surface.

Boundaries created & using sweep command drafted in Tooling direction.

Class-A&C were joined to perform final trim with Class-B surface.

Final Trim

Obtained final out put by trimming Class-A,B&C.

Dog House Creation

Dog House created by using the given data.

"C" is where the doghouse contacts the backside of the surface

• Doghouse wall thickness at the intersection of the part wall ( C ) should be 40% or less than the main wall stock ( T ).

• The height of ( B ) should be between 3.0 – 6.0 mm

Dog House bodies were created & added to main body using Boolean Operations.
