TITLE:- Odd Shaped Enclosure Using Advanced Sheet Metal options in NX Cad

OBJECTIVE:-

to make solid body and then convert it in sheet metal

INTRODUCTION :-

These basic guidelines for sheet metal fabrication include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.

Sheet Metal Fabrication is the process of forming parts from a metal sheet by punching, cutting, stamping, and bending. 3D CAD files are converted into machine code, which controls a machine to precisely cut and form the sheets into the final part.

Sheet metal parts are known for their durability, which makes them great for end use applications (e.g. chassis). Parts used for low volume prototypes, and high volume production runs are most cost-effective due to large initial setup and material costs.

Because parts are formed from a single sheet of metal, designs must maintain a uniform thickness. Be sure to follow the design requirements and tolerances to ensure parts fall closer to design intent and cutting sheets of metal.

DESIGN METHODOLOGY

DESCRIPTION (Need to explain tools/ Features used while designing)

Use the Extrude command to Creates a feature by extruding a section along a vector.
Use the Sheet Metal from Solid command to create a sheet metal body using a solid body to model it. The solid represents the inner void of an enclosure. You select the faces from the solid to be panel (web) faces, and edges between the faces to be bend regions.
Use the Flange command to create a single flange instance or multiple instances by selecting a single or multiple base edges.
Use the Jog command to create an offset or a step in a tab. You can use small jogs to provide clearance or rigidity to a part. The section for the jog must consist of a single profile that is linear or oblique across a planar face. NX creates the jog at any angle between 0 and 180° by lifting material on one side of the jog line and adding a flange between the two sides.
Use the Unbend command to unbend a portion of the part to construct cutout features, hole features, or deform features across a bend. You can later reform the bend to represent the true formed state of the model.
Use the Bead command to lift material along the contour of a sketch that simulates a stamping tool. Beads can also be created to stiffen sheet metal parts.
Use the hole to one or more solid bodies in a part or assembly with options for counterbored, countersunk, and threaded.
Use the Rebend command to return an unbend feature to its previous bent state. Any features added after the unbend operation are properly repositioned during the rebend operation.
Use the Flat Pattern command to create a 2D representation of the flattened 3D sheet metal part.
The Drafting application is designed to allow you to produce and maintain engineering drawings which comply with major national and international drafting standards.
