Box Assembly using NX Cad

Tittle:- Box Assembly using NX Cad

Objective:-

Write a detailed report on Sheet Metal Component with good explanation on Sheet Metal modelling tools applied throughout the modelling.

Introduction:-

NX is widely used CAD software for various purposes such as designing, engineering, manufacturing. It is used in various fields of different work.

Procedure:-

• Use Tab to create base of the Box.
• Use Flange (normal to XY) to create the side bend.
• Use Flange (normal to XZ) to create the side of box.
• Use closed corner to close the adjacent gap between corner.
• Use Flange
• Use Hem to create a U shaped profile.
• Use Mirror Body (using YZ plane) for mirroring the existing body.
• Use Unite to create a single solid body.
• Create a Dimple on front side of the Box.
• Use mirror feature to mirror dimple on the back side of the Box.
• Create a Dimple at the bottom of the Box.
• Unbend the Box.
• Rebend the Box.
• Create bead on the bottom of the Box.
• Use mirror feature for mirroring the rest of the bead.
• Use Hem for getting a smooth surface at the top of the Box.
• Create a Plane at the offset distance of 203mm from the XY plane.
• Create a Tab on new plane.
• Use Flange.
• Create a Lid using Tab, Flange and Hem options.
• Create a Hinge base using Tab.
• Use Flange and Hem to form the profile of Hinge.
• Then use Normal cutout to make the profile.
• Repeat it for the Hinge.
• Save the Model.

Description:-

Tab:-

it is the base for extruding a sketch to make a sheet metal in a planar face by changing its thickness.

Flange:-

It add flat surface or an angular surface on the edge of the surface to create an extended surface.

Closed Corner:-

This is used to fill the gaps or unfilled portion of the body.

Hem:-

It is used to modify the surface by folding edges of the sheet in order to improve ts characteristics.

Mirror Feature:-

This is used to mirror a feature along a specific direction.

Dimple:-

It is used to lift an area shown in the sketch to make an impression on the sheet metal.

Unbend:-

It is used for Unbending corners of the body.

Rebend:-

It is used for bending corners of the unbend body.

Bead:-

It is used to create a conture shape according to the sketch in the required direction with required punch/die radius.

Create Plane:-

It is used to create a plane at a specific point.

Normal Cutout:-

It is used to cut or create a gap in the sketch.

Break Corner:-

It is used to convert the sharp edges to the smooth edges of the corner.

Conclusion:-

Thus model has been designed and dimensioned with proper constraints as per the given instructions.
