Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1

Input:

The input was given as Class A surface.

Tooling Axis:

The component has walls that are perpendicular to the base of the component. Since the natural tooling axis was taken, (i.e) the axis normal to the base is taken as the Tooling axis.

Draft Analysis of Class A:

Draft analysis is done on the Class A Surface with respect to the Tooling Axis created.

The draft angle is maintained at 2.9 degrees. The design will not clear the draft angle since there is a deviation in class A provided.

Class B Surface:

Class B was created by offsetting Class A to the thickness of the component, (i.e.) 2.5 mm. The imperfect boundaries are repaired and joined into a single surface and B Surface is formed. The commands used here are Offset, Fillet, Untrim, Join, Multi Section Surface, Split, and Extrapolate.

Class C Surface:

The boundary is created on the Class A Surface and a sweep was done with the boundary as a guiding curve and Class A Surface as a reference surface at 90 degrees. This sweep is then joined with the Class A Surface to form C Surface.

Closed Surface:

In the final stage of the surface creation, The Class A Surface and Class B Surface are trimmed together to form an appropriate closed surface.

Part Body - Door Handle:

The part body is created using the close Surface command in Part Workbench with Closed Surface as the reference surface.

Rib Design:

Rib is designed at the required locations considering all the design rules. The created rib is duplicated and translated to the location of the second rib.

Screw Boss Design:

The Screw boss is designed at the required location considering all the design rules. The created screw boss is duplicated and translated to the location of the second screw boss.

Final Component:

Isometric View:

Front View:

Side View:

Top View:

Draft Analysis of the Final Component:

Draft analysis is done on the Component with respect to the Tooling Axis created.

The draft angle is maintained at 2.9 degrees for the component. The design will not clear the draft angle since there is a deviation in class A provided.

The draft angle is maintained at 0.49 degrees for the B side features.

Publication:

During this process of designing the Component, The Objects which are used frequently are published for ease of operation. Published Objects are,

• A Surface.
• Tooling Axis
• B Surface
