Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

Title of project

Casing design

Objective

The objective of this design is to create sheet metal casing with the help of nx advance sheet metal.

Intoduction

NX, formerly known as "unigraphics", is an advanced high-end CAD/CAM/CAE, which has been owned since 2007 by Siemens PLM Software. In 2000, Unigraphics purchased SDRC I-DEAS and began an effort to integrate aspects of both software packages into a single product which became Unigraphics NX or NX.

Sheet metal is metal 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. Sheets metal is a semi finished products that can be produced over a large area. Whereby sheets are genrallt light, thin,stable,elastic and flat.

Design approach method

procedure

• Create a sketch firs click on new file
• Add a solid sheet and cut out
• Again draw a sketch in the plane and exit and then click on bend button
• Add flanges
• After that click on break corner and apply to the edges.
• Unbend the metal sheet
• Add holes
• Add dimple
• Add beads
• Re bend the metal sheet
• Drafting

Description of tool /features

TAB

This feature is used to extrude the sketch with required thickness.

NORMAL CUT

Creates a cut profile to the tab with required depth.

BEND

This is to created by a single line on the surface,with required bend parameters.

FLANGE

Flange consist of one bend region and one web region with respective of the any edges with required length and angle.

BEND CORNER

Give a smooth radius to the sharp edges with required radius.

UNBEND

Unbend is a very important feature . before creating any feature the model the model should unbended for easy understanding.

HOLE

For creating a screw type , screw size hole feature is used.

DIMPLE

Creating a dent profile on the model is called dimple.

BEAD

Making a dent along the contour hole with respective to the direction required is bead.

REBEND

Rebend of unbend profile is called rebending. This is done in the final stage of model

screnshot of model

Drafting

Conclusion

Successfully crating the casing design in nx cad sheet metal.
