Advanced Sheet Metal Design Using NX Cad Challenge_7_ Metal bracket-II

                                                         REPORT ON THE METAL BRACKET

OBJECTIVE:

Design a metal bracket and 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 metalworking. and it can be cut and bent into a variety of shapes. Countless everday objects are fabricated from Sheet metal. Thickness can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6mm(0.25 in) are considered plate steel or "structural steel"

NX formerly known as "unigraphics", is an advanced high-end CAD/CAM/CAE. The NX softwere supports product developing and manufacturing at all stages of the life cycle. NX supports modeling of both complex surfaces and solid models. NX sheet metal provides a set of tools within the NX design of sheet metal parts, dependent on their material and manufacturing process.

With NX Sheet metal, formed and unformed representations of the parts are created closely following the industry workflows and best practice for bending calculations, tooling, and sheet metal features. The value lies in improving quality and reducing cost of sheet metal  parts by producing an accurate sheet metal pattern as the correct input for part manufacture, whether internally or to a supplier.

 DESIGN METHODOLOGY:

DESCRIPTION:

Sketch:It is a basic of any Design.

Contour flange:Used for Creating sketch required for contour flange, holes, normal cut out etc..

Normal Cut Out: This tool is used to cut the material by projecting a sketch onto the model and then cutting normal to the faces intersected by the projection.

Unbend:This features is used to unbend the adjacent bends and flatten them. It is used to create holes and bead.

Break Corner: It is used to round or chamfer the sharp corners of a Tab.

Hole: It adds holes on sheet metal part according to the specified sketch points.

Advanced flange: Add a flange along an edge using a bend angle or reference face.

Rebend: It is used to rebend the unbended corners after adding any features on the faces.

Gusset: It Creates a stiffening gusset on the part.

 

Flat pattern: It is used to create a flat pattern features from the formed sheet metal.
