Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

                                                                                                                        TITLE- DESIGN OF SHEET METAL CASING

AIM:We have to design the sheet metal casing in sheet metal environment of NX-CAD.

INTRODUCTION:  An object having a thickness range of (0.5 to 6)mm is called sheet metal component. A sheet metal component is created by bending, cutting, or deforming an existing sheet of metal having uniform thickness.

NX allows you to create the sheet metal components in a specific environment called the Sheet Metal environment. This environment provides all tools that are required for creating the sheet metal components.

                                                                                       

                                                                                                                                                 TRIMETRIC VIEW OF CASING

• REBEND

DESIGN APPROACH DESCRIPTION :  CREATE A NEW FILE NAME  NX_CASING_TUSHAR  UNDER SHEET METAL ENVIRONMENT OF NX.

1- SKETCH THE RECTANGLE OF DIEMENSION  (60 * 50)mm IN XY PLANE.

                                             

NOTE- BEFORE CREATING ANY SHEET METAL FIRST WE NEED TO FIX THE GLOBAL PARAMETERS THESE ARE THE DEFAULT VALUES AND WE CAN CHANGE THE VALUES LOCALLY AS PER THE DESIGN REQUIREMENTS.

2 -  CREATE THE TAB OF 3mm THICKNESS AS A BASE FEATURE.

                 

3-   DRAW A RECTANGLE (5*40)mm ON THE TOP OF THE TAB PARALLEL TO XY PLANE WHOSE EDGE IS COINCIDENT WITH LEFT EDGE AND ALSO SYMMETRIC WITH X-AXIS. 

   

4- CUT OUT THE RECTANGLE USING NORMAL CUTOUT COMMAND.

5-DRAW TWO PARALLEL LINE OF RANDOM LENGTH SYMMETRIC TO THE X AXIS WHOSE DISTANCE FROM THE EDGE IS 10mm.

6- USE BEND COMMAND TO BEND THE SHEET AS SHOWN BELOW.

7- ADD FLANGE OF LENGTH 5mm BY SELECTING THE EDGE AS SHOWN BELOW.

             

8- BREAK SHARP CORNER TO AVOID THE SHARP EDGES.

             

9- USE UNBEND COMMAND TO UNBEND THE SHEET, SELECT THE STATIONARY FACE

10-WE HAVE TO CREATE THE HOLE FOR THIS FIRST WE CREATE POINT AT THE EDGE USING INTERSECTION CURVE OPTION OF POINT COMMAND AFTER THAT USING THESE TWO POINTS CREATE THE MID POINT USING BETWEEN TWO POINT OPTION OF POINT COMMAND.

                                                                                                    

11- CREATE A HOLE OF M2 SIZE AND SIMPLE FORM.

12- CREATE A DIMPLE ON THE BASE FOR THAT WE NEED TO CREATE THE SKETCH ON THE BASE FACE (UPPER). SHAPE OF SKETCH IS CROSS TYPE OF DIEMENSION 5mm USING STUDIO SPLINE SELECT ALL THE 16 VERTICES ONE BY ONE.

 13- USING MOVE CURVE COMMAND ROTATE THE CURVE THROUGH THE 45 DEG.

                  

14-  DIMPLE IS CREATED OF DEPTH 1MM.

15- WE HAVE TO CREATE THE BEAD OF 5mm DIAMETER IN THE BASE FACE AS SHOWN BELOW AND AFTER THAT WE HAVE TO MIRROR BEAD FEATURE TO ALL THE CORNER.

     

16-AGAIN REBEND IT WITH REBEND COMMAND.

 DO FLAT PATTERN FOR THE DRAFTING PURPOSE.

              

CONCLUSION: WE STUDIED THE BASICS OF SHEET METAL AND SHEET METAL ENVIRONMENT OF NX CAD AND DESING OF CASING IN NX SHEET ENVIRONMENT IS COMPLETED AS PER THE DESIGN REQUIREMENT.
