Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

TITLE OF THE PROJECT

CASING DESIGN

OBJECTIVE

The Objective of this design is to create sheet metal casing with the help of NX advance sheet metal.

INTRODUCTION

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 bend into a variety of shapes. sheet metal is a semi- finished product that can be produced over a large area, whereby sheets are generally light, thin, stable, elastic and flat.

DESIGN METHODOLOGY (SIEMENS NX CAD SHEET METAL)

DESCRIPTIONS OF TOOL/FEATURE

• TAB

This command 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.

• NORMAL CUTOUT

To cut material by projecting a sketch onto the model and then cutting perpendicular to the face intersected by the projection. Use planer sketches or 3D curves to specify the section for the normal cut out.

• BEND

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

• FLANGE

To add a flat flange at an angle to a planar face and add a bend b/w the two. A flange consists of a bend region and a web.

• BREAK CORNER

This command is used to round or chamfer sharp corner of a tab or flange.

• UNBEND

Unbend creating any feature the model should be unbended for easy understanding.

• HOLE

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

• DIMPLE

Dimple command to lift an area of the model inside a sketch that simulates a stamping tool. It can create an indentation in a sheet metal part using a sketched section as the dimple outline.

• BEAD

This uses the bead command to lift material along the contour of a sketch that simulates a stamping tool. Bead can also be created to stiffen sheet metals.

• MIRROR

This feature is created replica of one or more profile with respective to axis required.

• REBEND

Rebending of unbend profile is called Rebending. This is done is the final stage of the model.

• FLAT PATTERN

This will automatically create a flat surface of the model which helps for manufacturing.

• DRAFTING

Converting a solid model to 2D sketch.
