Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure

DESIGN OF ODD ENCLOSURE USING SIEMENS NX CAD

Objective:

The main objective of this project is to design an Odd Enclosure by understanding different operations in Siemens NX-cad. Then drawing sheet is to be created for the designed sheet metal Enclosure.

Introduction:

The Sheet metal application provides an environment for the design of sheet metal parts used in Machinery, Automotive and Aerospace. Enclosures, Brackets and other parts are normally manufactured with break press. The sheet metal application are widely used in the,

• Aircraft Bodies
• Automobiles
• Utensils used for domestic purpose
• Beverage cans

In sheet metal application we can create a uniform thickness sheet metal parts using basic features such as flange, tabs and jogs. We can also do close corners, cutout and stiffening features. The complex sheet metal part can be designed in the solid model workbench and then we can convert into a sheet metal part. We can also import, clean up and convert a non-sheet metal part into a valid sheet metal part. Flat pattern sheet metal data can be used for the manufacturing process. The material parameters such as thickness, bend radii and bend relief can be easily set as default settings.

Version used here is NX 12.

Design Methodology:

Description:

Sketch: It is a basic and initial operation for creating any kind of sheet metal components.

Tab: It is a base feature that forms by extruding the sketch along a vector by providing thickness or adds material to a plane face.

Flange: It adds a flat flange on basis of edges at an angle to a planar face and adds bend between them.

Unbend: It flattens a bend and material adjacent to the bend.

Hole: It creates a whole on basis of circle created.

Bead: It lifts a material along the contour of a sketch that forms a stamping tool.

Rebend: It restores a bend

Flat pattern: It creates a flattened pattern from the formed sheet metal part.

Procedure for designing Odd Enclosure:

• At first sketch is drawn with required dimensions for extruding to form a solid body.
• Then these solid body is converted into Sheet metal by using command Sheet metal from solid on basis of selected faces and edges.
• One of the edges is selected for applying flange.
• Sketch is drawn by selecting the face opposite to above face for applying jog.
• Then unbend the part for applying required features. Sketches are drawn on face for applying beads.
• Holes are applied at different locations on surface of face.
• Whole part is selected to bend at required positions as earlier. Then flat pattern is applied to get a form of blank sheet.
• New draft file is opened by selecting base view for creating drawing of this Sheet metal.

Sheet metal enclosures
