Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

BOX MODELING

 

Objective:

                The objective of the project is create a model of box modeling by using NX cad.

Introduction:

                In this challenge, by using NX sheet metal application to design the sheet metal casing by using various tools like a tap, flange, normal cutout, bend, dimple and bead.

Design Methodology:

The following of the CASIGN DISIGN are modeled in Siemans NX cad.

• Sketch
• Tab
• Flange
• Close Corner
• Hem Flange
• Mirror Body
• Unite
• Dimple
• Mirror Feature
• Unbend
• Rebend
• Bead
• Datum Plane
• Break Corner
• Normal Cutout

 

Description:

SKETCH

 Sketch is the two dimensional representation of the model with respect to the plane/view from the outside of the model. In NX cad there are different sketch options available to create a sketch.  The following sketch options available in NX cad Line, Arc, Circles, Rectangle, etc...  .

TAB

Tab is use to create a base feature by extruding a sketch along a vector by a thickness value or by adding material to existing faces and bend regions of a sheet metal part.

FLANGE

Use this command to add a flat flange at an angle to a planar face and add a bend between the two.  A flange consists of a bend region 1 and 2.

CLOSE CORNER

close corner command is used modify the flange in one operetion and to close the corner where the two flange meet.

HEM FLANGE

 

Hem flange command to modify an angle of sheet matel part by folding it on to itself for the purpose of safe handling or to increase edge difness.

The Hem Flange is always oreated as a secondary feature on a base part.

DIMPLE

The dimple command use to lift an area of the model inside a sketch that simulates a stamping tool.To create an indentation in a sheet metal part casing a sketched section as the dimple outline.

 

MIRROR FEATURE

“Mirror Feature” is the command, copies, and pastes features on the model by mirroring through plane or surface.

UNBEND

In this command use to bend area is form to unbend the sheet metal. First the stationary face is selected after the bend area selected it will formed unbend.

REBEND

Use the rebend commands to unbend and rebend non-uniform thickness bends.

 

BEAD

Bead - It lifts material along the contour of a sketch that simulates a stamping tool, it is used for giving strength to the sheet metal. It is create some angle of bend the sheet metal along a sketch profile.

BREAK CORNER

The break corner command is use to create the round or chamfer sharp corner of a tab or flange.

NORMAL CUTOUT

Normal cutout is used to extracts volumes from sheet metal production principles. Cutting faces will be perpendicular to the sheet metal surface.

Conclusion:

By using various commands in sheet metal design BOX ASSEMBLY is created by various features.
