Week 10 - Challenge 1- Attachment Feature Creation (Ribs & Screw Boss)

AIM:

• Need to create door handle from given class A surface.
• Need to create tooling axis consider with the draft angles.
• Need to create Class B surface from Class A surface.
• Then create Class C surface and join the 3 surfaces.
• And finally we need to create a draft analysis for solid body.

PROCEDURE:

FEATURE TREE:

1.CREATION OF TOOLING AXIS:

• Tooling axis is a part pull direction from the cavity,when it was failure the part doesn't come from the cavity area,we need to give minimum draft angle to the part is 3 degree.

2.DRAFT ANALYSIS:

Draft analysis is use for find out weather the class A surface clear the 3 deg angle through out the area with cosideration of tooling axis.We are find out that from color codings and analyses under running points.

• In customize view parameters we need to select material mode
• Then we need to select draft analysis and take the compass to tooling axis.
• Then click on the Class A surface we easily got the color coding simulation of draft analysis.
• If we need to calculate perticular area of angle we need to use analyses under running points in the draft analysis wizard.
• Then using that arrow we can find out the angle on particular area.

CREATION OF CLASS B SURFACE:

• We need to offset the class A surface to 2.5mm,and using extract, extrapolate,Multiple surface and fill commands create the Class B surface.

CREATION OF CLASS C SURFACE:

• Using sweep,extrapolate and trim we need to create Class C surface.

• After final trimming we need to open part design interface to create the closed surface solid body.

CREATION OF CLOSED SURFACE:

• Join the Class A,Class B and Class C surface.
• And craete the closed surface to convert solid body.

CREATION OF RIBS AND SCREW BOSSES:

RIBS:

Ribs are used for giving additional strength to the part.It is a thin feature contain a draft angles,height and thickness with design considerations.

CREATION OF SCREW BOSSES:

• Screw bosses are used for mating the parts to assembly parts.
• 

DRAFT ANALYSIS AFTER SCREW BOSSES AND RIBS:

CONCLUSION:

Class A surface sucessfully converted into solid body and it is ready for manufacturing.
