Advanced Sheet Metal Design Using NX Cad_Bracket

TITLE OF THE PROJECT: Advanced Sheet Metal Design of Bracket using Siemens NX CAD Sheet Metal application.

OBJECTIVE: To Design the BRACKET Sheet metal part using Sheet metal tools and drafting the part in flat pattern view for manufacturing and Design purpose.

INTRODUCTION:

Siemens NX is a software used for multiple engineering disciplines like CAD/CAM/CAE modules.

NX Sheet Metal Design is used for Design and Drafting of Sheet metal parts with its user friendly handy tools that converts the input sketches to desired design requirements and checks for the manufacturing feasibiltiy of the designed sheet metal part by flattening the part. The following NX Sheet metal tools are used to design this part, which is described as follows:

CONTOUR FLANGE: Creates a base feature by extruding a sketch along a vector, or adds material by sweeping a sketch along an edge or chain of edges.

NORMAL CUTOUT: Cuts material by projecting a sketch onto the model and then cutting perpendicular to the faces intersected by the projection.

BREAK CORNER: Rounds or Chamfers a sharp corner of a tab or flange.

UNBEND: Flattens a bend and the material adjacent to the bend.

REBEND: Restores an unbend feature to its previous bent state, along with any features added after the unbend feature.

BEAD: Lifts material along the contour of a sketch that simulates a stamping tool.

FLAT PATTERN: Creates a Flat Pattern feature from the formed sheet metal part.

DESIGN METHODOLOGY:

DESCRIPTION: 1) Draw the profile sketch as required for the design in the Front plane and Use Contour Flange tool as Base Tab.

2) Apply Normal cutout tool on the part with the defined sketch as required. Apply Break corners to remove the sharp edges on the contour flange part.

3) Use Unbend tool to Unbend the part and then perform Bead and Simple Hole operations on the part as required by using Bead tool and Hole tool.

4) Finally, use the Re-Bend tool to Re-Bend the part to original shape and Use Flat Pattern tool to Flatten the sheet metal part.

CONCLUSION: Hereby, Designing the BRACKET Sheet metal part, learnt to use the Sheet metal tools like Contour Flange, Normal cut-out, Unbend, Re-bend, Bead and Flat Pattern.
