Advanced Sheet Metal Design Using NX Cad _Odd Shaped Enclosure
TITLE OF THE PROJECT: Advanced sheet metal design of ODD_SHAPED_ENCLOSURE .
OBJECTIVE: To Design the ODD_SHAPED_ENCLOSURE Sheet metal part using Siemens NX CAD Sheet metal application 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 sheet metal tools are used in this design, with it's description is as follows:
SHEET METAL FROM SOLID: Builds a sheet metal modelthat takes it's shape from a collection of planar faces.
FLANGE:Adds a flat flange at an angle to a planar face and adds a bend between the two.
JOG : Modifies the model by lifting material on one side of a sketch line, adding a flange between the two sides.
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.
HOLE: Adds a hole to one or more bodies in a part or assembly with options for Counterbored, Countersunk and Threaded.
FLAT PATTERN: Creates a Flat pattern feature from the formed sheet metal part.
DESIGN METHODOLOGY:
DESCRIPTION:
1) Draw the sketch profile in the front plane and use the Extrude tool to extrude the part as required.
2) Use SHEET METALFROM SOLID tool to convert the solid body to sheet metal part.
3) Add Flange on one side of the sheet and add Jog on other side of the sheet as required.
4) Unbend the part using Unbend tool and perform BEAD and HOLE operations on the sheet face as required by using Bead tool and Hole tool.
5) Finally, Re-Bend the part and perform the Flat Pattern operation by selecting the centre face of sheet metal using Flat Pattern tool.
CONCLUSION: Design of Odd Shaped Enclosure is finished with the use of Solid part and converting the solid part into Sheet metal part by sheet metal tools. By this design, learnt sheet metal tools like Jog, Bead, converting sheet metal from solid, Unbend, Re-Bend and Flat Pattern of the sheet metal part.
