Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

TITLE - CASING DESIGN USING NX-CAD.

OBJECTIVE - To create a casing using sheetmetal workbench tools following all the design rules and parameters in used    sheetmetal .

INTRODUCTION - Nx cad software is a simple and powerful tool which has wide variety of application in various  industries such as automobile , medical , aircraft etc . using the sheetmetal workbench from nx , we will create the required part .  . 

DESIGN METHODOLOGY - 

1- Setting sheet metal preference . 

2- Creating the sketch of base tab .

3 - Using tab command.

4- Creating normal cutout . 

5- Bending the sheetmetal .

6- Creating flanges .

7- Adding break corner .

8- Unbending the part .

9- Creating holes . 

10- Creating sketch for dimple .

11- Creating dimple.

12- Creating beads .

13- Mirroring the beads . 

14- Rebending the part . 

15 - Creating flatpattern and drafting .

16 - Top view .

17- Front view.

18- Side view . 

19 - Isometric view . 

20- Drafting sheet . 

DESCRIPTION - 

1 - TAB COMMAND -   

 This command is used to create a base feature by extruding sketch along vector by a certain thickness value or by adding material to existing faces and bend regions of sheet metal parts . 

2 - NORMAL CUTOUT - 

This command is used to cut material by projecting a sketch onto a model and then cutting perpendicular to the faces intersected by projection . 

3 - BEND - 

This command is used to bend the material using a sketch as input line for bend . bend is given considering the K factor , bend radius . 

4 - FLANGE - 

This command is used to add a flat flange at an angle to planar face and add a bend between the two . 

5 - BREAK CORNER -

This command is used to round or chamfer sharp corners of tab or flange . 

6- UNBEND - 

This command is used to unbend the material to create a flat sheet .

7 - HOLE - 

This command is used add hole in sheet metal body . this holes can be clearance for bolts, screws etc . 

8 - STUDIO SPLINE - 

This command is used to create spline in sketch. this spline can be created taking points as reference . 

9- MOVE CURVE - 

This command is used to move the selected curve in horizontal , vertical or it can also be rotated .

10 - DIMPLE -

This command is used to create an identation in sheetmetal part using sketched section as input for dimple . it can lift the area of model inside a sketch that simulates a stamping tool . 

11 - BEAD - 

This command is a stiffening deature . it stiffens the sheetmetal . it is used to lift the material along contour of sketch that simulates stamping tool . 

12 - MIRROR FEATURE - 

This command is used to mirror or duplicate a part along a plane. 

13 - REBEND - 

This command is used to bend the sheetmetal part that we had previously bend . 

14 - FLATPATTERN - 

This command is used to create the 2D drawing of the sheet metal part . 

15 - DRAFTING - 

This command is used to create drafting or detailed drawing of sheetmetal part . 

CONCLUSION - The sheet metal casing is created using the tools of NX cad .
