Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

                                                                                   BOX ASSEMBLY  

1. INTRODUCTION:-

• STARTNX12.0 AND CREATE A NEW SHEET METAL MODEL CALLED CASING.PRT
• CREATE A SKETCH INTHE XY PLANE AND DRAW A RECTANGLE CENTRED AT THE ORIGIN WITH AN XLENGTH OF 200MM AND a Y WIDTH OF 150MM.
• EXIT THE SKETCH MODE. 

• SELECT TAB FEATURE GIVE 1MM SHEET THICKNESS.

2. ADDING FLANGE:-

SELECT 2 SIDE EDGES FOR FLANGE GIVE LENGTH NORMAL TO XY DIMENTION200MM ON 90 DEGREES AND BEND RADIUS 10MM.

SELECT 2 SIDE EDGES FOR FLANGE GIVE LENGTH NORMAL TO XZ DIMENTION 70MM ON 90 DEGREES AND BEND RADIUS 10MM.

BEND RELIEF & CORNER RELIEF SELECT IS  NONE 

3. ADDING CLOSED CORNER:- 

CORNER PROPERTIES - CLOSED GAP-0

 4.ADDING FLANGE :-

SELECT EDGES GIVE LENGTH DIMENSIONS 0.002MM BEND RELIEF &CORNER RELIEF IS NONE

 5.ADDING HEM:-

SELECT OPEN HEM, SELECT MATERIAL OUTSIDE ,BEND REDIUS 0.51MM, FLANGE LENGTH 3MM

6.MIRRIOR:-

7.UNITE:-

SELECT TOOL BODY & TARGET BODY

8.ADDING DIMPLE :-

1.CREATE SKETCH SELECT DIMPLE FEATURE THEN 2MM DEPTH MATERIAL OUTSIDE , PUNCH RADIUS , DIA RADIUS , CORNER RADIUS IS 1MM

2. CREATE RECTANGLE  ON THE BOTTOM SIDE 350X50MM THEN SELECT THE DIMPLE FEATURE 

9.UNBEND :-

10. DIMPLE:-

CREATE A 15MM DIA CIRCLE THEN SLECT DIMPLE FEATURE SELECT CROSS SECTION CIRCULAR , DEPTH AND DIA IS 2MM AND DIA RADIUS IS 2MM 

MIRROR DIMPLE 

11. ADDING HEM :-

 SELECT HEM FEATURE SELECT MATERIAL OUTSIDE FLANGE LENGTH IS 2MM, RELIEF DEPTH AND WIDTH IS 1MM

12. CREATE NEW  DATUM PLANE:-

CREATE NEW DATUM PLANE AT 203MM DISTANCE THEN CREATE SKETCH THEN SELECT TAB FEATURE 2MM THICKNESS 

13. ADDING FLANGE :-

1.SELECT EDGE LENGTH IS 3MM , MATERIAL OUTSIDE , BEND RADIUS 0.5MM

2.CREATE  55X20MM RECTANGLE 17MM DISTANCE FROM ORIGN

3.  SELECT TAB 1MM THICKNESS 

4.ADDING FLANGE ON TAB 4MM LENGTH ON 40 DIGREE ANGLE, BEND RADIUS 0.5MM

5. ADDING ONE MORE 4MM LENGTH OF FLANGE 

14.ADDINGE HEM:-

1.SELECT HEM FEATURE THEN SELECT OPEN LOOP , BEND RADIUS 5MM, ANGLE 325 BEND OUTSIDE 

2.CREATE A SKETCH 40MM FOR 2 CUTOUTS BEFORE UNBENDING HINGE 

3.SELECT NORMAL CUT 

4.MIRROR FEATURE 

 15. ADDING 1MORE HINGE :-

1.CREATE RECTANGLE ON TOP OF THE CAP THEN SELECT 1MM THICKNESS OF TAB

2.ADDING FLANGE LENGTH OF THE FLANGE IS 13.6MM AND ANGLE OF THE FLANGE IS 37DIG. BEND RADIUS IS 1MM

3.ADDING OPEN HEM OF 5MM BEND RADIUS AND 325 SWEEP ANGLE MATERIAL OUTSIDE  

 

4. UNBEMD HINGE THEN SKETCH 9 RECTANGLE FOR 4 CUTOUTS
