Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly
SHEET METAL DESIGN OF BOX ASSEMBLY USING NX CAD
Objective :
The objective of the project is to create the box assembly using NX CAD sheet metal designing
Introduction :
Sheet Metal -
The sheet metal is formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metal working, and it can be cut and bent into a variety of shapes. The metals which are less 6 mm thickness are considered as sheet metals. The sheet metal is available in flat pieces or coiled strips.
The various forming processes that are used to deform the sheet metals are -
Bending
Curling
Deep drawing
Hemming and Seaming
Punching
Blanking and Peircing
Rolling, Spinning and Stamping
Sheet metal is used in automobile and truck bodies, airplane fuselages and wings, medical tables, roofs for buildings and many other applications.
NX CAD in sheet metal -
NX sheet metal design software incorporates material and process information in sheet metal-specific modeling features: bends, flanges, tabs, cutouts, beads, dimples, louvers, corner and edge treatments, patterns and other formable features. You can also quickly convert solid models to sheet metal components, and create sheet metal parts that enclose other components.
NX Sheet Metal-specific features such as flanges, tabs, jogs, corner conditions, and drawn cutouts & many more along with productivity enhancements such as – automatic bend reliefs.
The software also provides common modeling features typically used in sheet metal design, such as holes and slots, as well as other essential capabilities such as copy, paste, and mirror.
The application provides defaults for sheet-metal-specific properties such as material – thickness, bend radius, and bend relief. You can easily change these defaults.
Design methodology :
Description :
Create the tab from the rectangle of 200x150 mm
Create the flange as shown in image
Create the hem
Mirror body and unite them
Create the emboss and bead
Close hem the sharp edges of the box
Create the top cap for box
Create the hinge using open loop hem and mirror the body
Do the same for the top hinge also

Conclusion :
The given box assembly model is successfully created using NX CAD sheet metal and drafting views are created.
