Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure
Odd Shaped Enclosure
Objective -
To Design a Odd Shaped Enclosure using NX sheet metal workbench
Introduction -
Sheet metal ismetalformed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms usedin
metalworking, and it can be cut and bent into a variety of shapes. Countless everyday objects are fabricated from sheetmetal. Thicknesses can vary significantly; extremely thin sheets are consideredfoilor
leaf, and pieces thicker than 6 mm(0.25 in) are considered
plate steel or "structural steel".Sheet metal is available in flat pieces or coiled strips. The coils are formedby running a continuous sheet of metal through a
roll slitter .In most of the world, sheet metal thickness is consistently specifiedin millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known asits
gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge toabout 7 gauge. Gauge differs between ferrous
(iron-based)metals and nonferrous metals such as aluminum or copper. Copperthickness, for example, is measured in ounces, representing the weight of copper contained in an area of one square foot. Partsmanufactured from sheet metal must maintain a uniform thickness for ideal results.There are many different metals that can bemade into sheet metal, such as
aluminiumbrass copper,steel,tin,nickelandtitanium. For decorative uses, some importantsheet metals includesilver,gold, andplatinum
(platinum sheet metal is also utilized as acatalyst).Sheet metal is used inautomobile and truck (lorry) bodies, airplane fuselages and wings, medical tables, roofs for buildings (architecture), and manyother applications. Sheet metal of iron and other materials with high magneticpermeability, also known aslaminated steelcores, has applications intransformersand
electric machines. Historically, an important use of sheet metal was inplatearmor worn bycavalry, and sheet metal continues to have many decorative uses, including inhorse tack
. Sheet metal workersare also known as "tin bashers" (or "tin knockers"), a name derived from the hammering of panel seams when installing tinroofs.
DESCRIPTION:
Sketching - Making a 2d drawing such as curves, arcs, cirlces, points, rectangles and many options to create a drawing or tocreate features for upcoming designing.
Extrude - It is to make the 2d sketch in a 3 dimensional body or object by defiining its thickness.
Sheet metal from solid -
It converts the solid shaped part to shaped sheet metal, and is available in only sheet metalapplication.
Flange -
it adds an angular or flat surface on the edge of the surface to create an extended surface with the requireddirections,
Jog - It modifies the sketch by lifing on the one side and adds flange of required length between the two end sides.
Unbend - It is to flatten the bend sheet metal to form a flat sheet. It helps in making a extra features like bead, normalcutout on the sheet metal after bending.
Bead - This is to create a contour shaped accordingly to their sketch in the required direction with required punch/dieradius,
Hole - It is to create a hole on sketch, or to create a counter bored, counter sink and several hole options to do.
Bead - It is to create a contour or projection on the sheet, as respected with the created sketch.
Flat pattern - It creates the flat pattern of the sheet metal in a seperate sheet for it dimensions and details of the mode
Drawing sheet
Conclusion -
By doing this project I have learned some new NX sheet metal work bench tools like Hem flange, Closed corner,flatting tool. Understood
the Design Methodology to create this type of sheet metal parts.
