Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

Modelling of the Sheet Metal Box.

Objective
Designing of sheet metal box using NX Cad.

Introduction
Our aim is to design sheet metal box assembly using, various tools and commands in NX cad.

Flowchart

Description
The sheet metal box, hinge, lid are designed by using NX Cad.
The box, hinge, lid collectively forms the sheet metal box assembly.

Features Used

Rebend

There are various sub-features are available inside every feature, we have to use them according to our requirement or necessity.

Sketch
Creates a 2D sketch in the current application. Use the direct sketch tools to add curves, dimensions, constraints, etc.

Tab
Creates a basic feature by extruding a sketch along a vector by adding thickness value, or adds material to a planar face. Additional planar selections can be added to generate bends as a part of the base feature.

Flange
Adds a flat flange at an angle to a planar face and adds a bend between the two.

Closed Corner
This command closes a corner where two adjacent flanges meet by extending the bends and flanges.

Hem Flange
Modifies the model by folding the edge of a sheet metal flange over onto itself for the purpose of safe handling or to increase edge stiffness.

Mirror Body
This command copies a body and mirrors it across the selected plane.

Unite
This commands combines the volume of two or more solid bodies into a single body.

Dimple
Dimple lifts an area of the model inside a sketch that simulates a stamping tool.

Mirror Feature
This command copies a feature and mirrors it across a the selected plane.

Bead
Bead command lifts material along the contour of a sketch that simulates a stamping tool.

Datum Plane
This command creates a datum plane to construct other features.

Break Corner
Break corner command rounds or chamfers a sharp corner of a tab or flange.

Unbend
Unbend flattens a bend and the material adjacent to the bend.

Normal Cutout
Normal Cutout cuts material by projecting a sketch onto the model and then cutting perpendicular to the faces intersected by the projection.

Rebend
Restores an unbend feature to its previous bent state, along with any features added after the unbend feature.

Conclusion
The box, hinge and lid are designed by using various commands of NX Cad.
This box, hinge and lid collectively forms sheet metal box assembly.
