Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly
BOX ASSEMBLY USING NX CAD
Objective -
To create a box assembly using NX cad sheet metal application, for production.
Introduction -
Sheet metal is metal formed by an industrial process into thin, flat pieces of. Sheet metal is one of the fundamental forms used in metal working and it can be cut and bent into a variety of shapes. Countless everyday objects are fabricated from sheet metal.
Applications of sheet metal are Aircraft bodies, Automobile bodies, Utensils used for domestic purpose, Bevarage Cans. The Sheetmetal Application provides an environment for the design of sheetmetal parts used in Machinery,Automotive,Aerospace etc.
Design Approach -
Description -
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.
