Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure

SHEET METAL ODD SHAPE ENCLOSURE

OBJECTIVE:- Sheet metal odd shape enclosure using Sheet Metal features in NX CAD.

INTRODUCTION:- NX Sheet Metal provides a set of tools within the NX design environment that allows for simple and fast design of sheet metal parts, dependent on their material and manufacturing process, the most common of which is straight brake sheet metal forming.

DESIGN METHODOLOGY:- There are some step ot stages follows as shown as....

• Create a solid body: create solid body that encompasses the interior volume of the enclosure shape, using the modelling tools. using Extrude tool, create a feature extruding a section along the vector.
• Wrap the solid body with sheet metal: Builds a sheet metal model that takes its shape from collection of planer faces.
• Changing the parameters preferences accordingly.
• Add a flat flange at an angle to a planar face by using Flange command.
• Modifies the model by lifting material of one side of the sketch line, adding a flange between two sides by using Jog tool.
• Flatten the bend and the material adjacent to the bend face by using Unbend command.
• Lift material along the contour of the sketch that simulates the stamping tool by using Bead command.
• Add a hole to one or more solid bodies in a part with counterbored, countersunk and threaded by using Hole command.
• Rebend command using to restores an unbend features to its previous bent state, along with any features addad after the unbend features.
• Create flat pattern feature from the formed sheet metal part by using Flat pattern tool.
• Drafting: Creates a model based view on the drawing sheet by using Base View Tool

Descrption:-

1. Sketch:Creat a sketch in XY plane and draw a rectangle by using lines with an certain dimesions.
2. Extruding a Solid Body:Exit the sketch mode, use the Extrude button for creating first rectanglar model, select the specify vector with certain value.
3. Wrap the solid body into sheet metal by using Sheet Metal From Solid Command, Select the web face and then select the bend edges of validate parameter.
4. Flange: Click the Flange button, use a length of certain value and apply the flanges normal to plane on the edge of the metal sheet as correponding symmetrical egde.
5. Adding Another Flange: Click the Jog button, use a length of certain value and the model by lifting material of one side of the sketch line, adding a flange between two sides.
6. Unbending the Face: click the Unbend button, select as stationary face of the metal sheet for bending face one of its adjacent faces.
7. Adding bead: Click on the Bead button, select the curve using sketch feature and select the bead properties along with validate parameter.
8. Adding Hole: Click on the Hole button, select the general hole type and specify the point with simple form validate parameter.
9. Rebend: Click on the rebend button select the bend faces respectively to restores an unbend features to its previous bent state, along with any features addad after the unbend features.
10. Creating Flat Pattern: Click on the Flat Pattern Button, Select the face and edge for the orientation method.
11. Drafting: Creates a model based view on the drawing sheet by using Base View Command, Click on the Base view button and select the view of model and its projection available on the drawing sheet.

CONCLUSION:-NX sheet metal design software incorporates material and process information in sheet metalspecific modeling features: bends, flanges, tabs, cutouts, beads, dimples, louvers, corner and edge treatments, patterns and other formable features. You can also quickly convert solid models to sheet metal components, and create sheet metal parts that enclose other components.l
