Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd_shaped_Enclosure
ADVANCED SHEET METAL DESIGN OF AN ODD SHAPED ENCLOSURE USING NC CAD
OBJECTIVE:
- To design an odd-shaped enclosure using NX CAD.
- To create drafting of the same part in the A4 Sheet.
INTRODUCTION:
Sheet metal is a metal formed by an industrial process into thin, flat pieces. Sheet metal can be cut and bent into a variety of shapes. Countless everyday objects are fabricated from sheet metal.
NX is formerly known as "Unigraphics".
DESIGN METHODOLOGY:
1. Set the sheet metal preferences
2. extrude a sketch to obtain a solid model
3. create a sheet metal from the extruded solid using sheet metal from solid
4. create features like flange and jog
5. unbend the sheet metal to create bead and hole
6. rebend and create a flat pattern
DESCRIPTION:
Tools with their functions:
Sketch: it is used to create a profile.
Tab: it is used to create a base feature of sheet metal.
Flange: it is used to create extended parts on sheet metal.
Unbend: it is used to unbend the sheet metal by taking any face as a stationary face.
Rebend: it is used to rebend all the bent faces.
Dimple: it is used to lift an area of the model inside a sketch that simulates a stamping tool.
Bead: it is used to lift material along the contour of ta sketch.
Flat pattern: it is used to create a 2D representation of flattened 3D sheet metal.
Normal cutout: it is used to cut a portion of sheet metal.
Bend: it is used to bend the sheet metal.
Flanges: they are added to the ends of the bends.
Break corner: it is used to create a smooth edge at the sharp corners.
