Advanced Sheet Metal Design Using NX Cad - Odd Shaped Enclosure

ADVANCED SHEET METAL DESIGN OF AN ODD SHAPED ENCLOSURE USING SIEMENS NX CAD

OBJECTIVE:

• To design an odd shaped enclosure using Siemens NX Cad.
• To create a drafting of the same part in 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 formerly known as "unigraphics", is an advanced high-end CAD/CAM/CAE software. NX Sheet Metal provides a set of tools within the NX design environment that allows for simple and fast design of sheet metal parts.

DESIGN METHODOLOGY:

DESCRIPTION:

Tools Used & their functions:

SKETCH: It is used to create a profile.

EXTRUDE: It is used to create a solid or sheet body by selecting a section of curves, edges, faces, sketches, or curve features and extending them a linear distance.

SHEET METAL FROM SOLID: It is used to create a sheet metal part from a solid by forming a layer of sheet metal around the solid model.

FLANGE: It is used to create a extended part of a sheet part.

UNBEND: It is used to unbend the sheet metal by taking any one face as a stationary face.

REBEND: It is used to rebend the sheet metal.

HOLE: It is used to create a hole of various types in the part.

BEAD: It is used to lift material along the contour of a sketch.

JOG: It is used to create an offset or a step in a tab feature.

Order of Usage of tools:

• The sheet metal preferences are set as required.
• A required sketch is drawn in the XY plane.
• The sketch is extruded using EXTRUDE tool.
• Sheet metal is obtained from the solid model using SHEET METAL FROM SOLID tool.
• FLANGE is added to the edge of the sheet metal.
• A sketch is drawn and JOG tool is used to offset the surface as required.
• The sheetmetal is unbended using UNBEND tool.
• BEAD is added using a linear sketch.
• HOLES are added as required.
• The sheet metal is then again rebended using REBEND tool.
