Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

 AIM : Advanced sheet metal design using NX cad challenge 2 Box Assembly .

OBJECTIVE : To design a BOX Assembly using Siemens NX sheet metal application.

INTRODUCTION :

                 SHEET METAL is metal formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metal working & it can be cut & and bent into a variety of shapes. Conties averyday objects are fabrication from sheet metal.

Applications : Aircraft bodies, automobile bodies, utensils used for domestic purpose, beverage cans.

the sheetmetal application provides an environment for the design of sheetmetal parts used in machinarey , automotive, aerospace etc. 

By using sheetmetal Application We can do :

• Import, clean up, & a non-sheetmetal part to a valid sheetmetal part 
• Export lat pattern data of sheetmetal part to a valid sheetmetal part.

Design Methodology :

Description :

FEATURES USED :

SKETCH: It is basic command to draw to draw 2D models.

TAB : This command is used to create a base feature by extruding a sketch along vector by a thickness value or by adding material to exixting faces & bend regions of sheetmetal part.

FLANGE : This command is used to add a flat flange at a angle to the planar face & a bend between the two. A flange consists of bend region & a web.

CLOSED CORNER : This command is used to modify two flanges is one operation & to close the corner where the two flanges meet .

HEM FLANGE : This command is used to modify an edge of a sheetmetal part by folding it on to itself for the purpose safe handling or to increase edge stiffness.

MIRROR BODY : This command is used to mirror the part w.r.t the required axis.

UNITE : This command is used to combine the two parts into one part .

DIMPLE : This command is used to lift an area of the model inside the sketch that stimulates a stamping tool.

MIRROR FEATURE : This command is used to mirror the required sketch to other side with reference to the axis.

UNBEND : This command is used to flatten the 3D model by selecting one stationary face.

REBEND : This command is used to rebend the flatern sheet material.

BEAD : This command is used to lift material along contour of a sketch that stimulates a stamping tool. Bead can also be created to stiffen sheet material.

CONCLUSION :

                 By performing this task , I have learned how to use features like tab , break corner , closed corner , dimple, hem flange, bead, rebend , datum plane, datum plane coordinate system , flat pattern, mirror feature, mirror body , unite, normal cutout & unbend by creating a box assembly.
