Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure

OBJECTIVE

The objective of the project is to design a sheet metal odd shaped enclosure using Sheet metal application in Siemens NX and a drawing sheet needs to be drafted for the designed model using drawing application in NX.

Sheet metal is a 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 everyday objects are fabricated from sheet metal.

NX, formerly known as "unigraphics", is an advanced high-end CAD/CAM/CAE, which has been owned since 2007 by Siemens PLM Software. In 2000, Unigraphics purchased SDRC I-DEAS and began an effort to integrate aspects of both software packages into a single product which became Unigraphics NX or NX.

DESIGN METHODOLOGY

DESCRIPTION

FEATURES USED FOR CREATING BOX ASSEMBLY

• EXTRUDE – Creates a feature by extruding a section along its vector.
• BEND – Modifies the model by bending material on one side of 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.
• 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.
• BEAD – Lifts a 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 from the formed sheet metal part.

PROCEDURE FOR DESIGNING THE BOX ASSEMBLY

• First a solid body was created by drawing the required sketch and using the extrude command.
• The extruded solid body was wrapped with the sheet metal using sheet metal from solid option.
• Then the solid body must be hidden and then the required flange was created on the left side of the enclosure.
• Then for the right edge a line was drawn and by using it a Jog feature was applied.
• Then for creating some other features like Bead, hole the unbent operations was carried out.
• After unbending the required beads were created along with the necessary holes on the sheet metal surface.
• Then the re-bent operation was carried out.
• Finally the flat pattern view was generated and the drafting (drawing sheet) for the flat pattern view was created and saved successfully.

CONCLUSION

Thus the project has been completed by designing a sheet metal Enclosure with odd shape using the sheet metal application in Siemens NX and then the required drawing sheet were created using the drawing application in NX.
