Week 9 - Attachment Feature Creation - Challenge 2

Aim:

Create the Dog House for the Door Trim considering the design rules and perform the draft analysis for class A and create the final close body component and perform the draft analysis.

OBJECTIVE:

To create DOOR TRIM LOWER using given class A

To create tooling axis

To create dog house

To perform draft analysis

Consider the thickness of the part to be 2.5 mm.

CLASS A SURFACE:

The above image represents the class A surface given as input.

GENERATING TOOLING AXIS:

1. The flat face from the given class A surface is identified and extracted.
2. A point is plated using point option and on surface method.
3. A line is created by using line command normal to surface plane. Thus TOOLING AXIS is created.

SIDE CORE AXIS:

1. The side core axis is created using point and direction method with initial point used for tooling axis and using the x axis for this component as direction.

CLASS B:

1. The given surface is offset for the given thickness of 3mm.
2. Few open patches are found in the class B surface.
3. These patches are closed by creating a boundary and exploited tangential or curvature to the surface for the suitable surfaces.
4. Then they are trimmed.
5. Fillet values are measured and applied. CLASS B surface is created.

CLASS C

1. The class C surfaces are created part by part up to required distance.
2. The edges are selected and boundary is created.
3. The outer edges are swept using boundary reference surface.
4. The cut out portions are created using tooling axis method using tooling axis

FINAL SURFACE:

1. The class A and class C surfaces are joined together.
2. The joined surface is trimmed with class B surface and Final surface is created.

CLOSED SURFACE CREATION:

1. By going to part design and using closed surface option. The Thickened component is created.
