Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design
TITLE OF THE PROJECT:-Advanced sheet metal design using Siemens NX CAD-CASING
OBJECTIVE:- To design a sheet metal casing and to create a draft of it using NX CAD
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 bent into a variety of shapes. Countless everyday objects are fabricated from sheet metal. Thicknesses can vary significantly; extremely thin sheets are considered foil, and pieces thicker than 6 mm (0.25 in) are considered plate steel or "structural steel"
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.
DESIGN METHODOLOGY
Design methodology is explained by flowcharts as follows:-
DESCRIPTION
Sketch:- It is a basic of a design
Tab:- It is used to create base feature of the sheetmetal by extruding a sketch along a vector by a thickness value.
Normal cutout:- Cuts material by projecting a sketch onto the model and then cutting perpendicular to the faces intersected by the projection
Bend:- Modifies the model by bending material on one side of a sketch line, adding a bend between the two sides.
Flange:- Adds a flat flange at an angle to a planar face and adds a bend between the two.
Break corner:- Rounds or chamfers a sharp corner of a tab or flange.
Unbend:- Flattens a bend and the material adjacent to the bend.
Hole:- Adds a hole to one or more solid bodies in a part or assembly with options for counterbored, countersunk, and threaded.
Dimple:- Lifts an area of the model inside a sketch that simulates a stamping tool.
Bead:- Lifts material along the contour of a sketch that simulates a stamping tool.
Rebend:- Restores an unbend feature to its previous bent state, along with any features added after the unbend feature.
Flat Pattern:- Creates a flat pattern feature from the formed sheet metal part.

CONCLUSION:-
By performing this ,i have learned how to use basic features/tools like tab,flange,bend,hole,unbend,rebend,flatpattern etc.by designing casing.
