Advanced Sheet Metal Design Using NX Cad Challenge_5_Odd Shaped Enclosure
Title: Odd Enclosure
Objective: Designing a sheet metal Odd enclosure using NX CAD tool
Introduction: This corresponding part is a sheet metal Odd enclosure which has been designed with NX CAD tool. The part is converted from solid to sheet metal. The part consists of feature such as holes, louvers, drawn holes, dimple with rectangular cut-out and beads.
Design Methodology:
Sketch of trapezium shape is drawn> then the sketch is extruded> the part is converted into sheet metal> Flange is make on LH side> Jog is made on RH side> unbending of part> Beads re placed in position> Holes are provide, Qty.04 > A louver is added> A Dimple is added> A rectangular cut-out is added on the dimple > A punched hole is added on top face> Re-bend of the part> Flat pattern is generated.
Description:
Sketch of trapezium shape is drawn on YZ plane of dimensions 200x100mm with angle 60 degree in Sketch command. Then it is extruded using Extrude command. All the above has been done in modelling workbench. Now the workbench is changed to Sheet metal. The solid is then converted into sheet metal using Convert to Sheet metal from Solid command. The Rip command inside this command is also used to rip off the edges. A flange of 20mm is added using Flange command. On the other side a jog is made of 20mm depth using Jog command. Unbending of part is done by using Unbend command. Two beads of 2mm radius is added by using Bead command. Also, four holes of type General Hole is made using Hole command and the dia is 25mm. On one of the remaining sides, a louver of width 15mm and depth 10mm is created using Louver command and at last on the last side, a dimple with depth of 2mm is created using Dimple command. A rectangular cut-out is also added on the dimple using Normal Cutout command. Lastly, on the top face of the part a punched hole of 30mm dia and depth of 10mm is created using Drawn Cutout command. Re-bending of the part is done using Rebend command and flat pattern is created by Flat Pattern command.
Conclusion:
Hence, above sheet metal OddnEnclosure has been design with minimum possible operations.
