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 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 and it can be cut and bent into variety of shapes. Countless everyday objects are fabricated from sheet metal.
Applications: Aircraft bodies, Automobile bodies, Utensils used for domestic purpose, Beverage Cans etc.
The sheet metal application provides an environment for the design of sheetmetal parts used in machinery, automotive, aerospace etc.
DESIGN METHODOLOGY:
DESCRIPTION:
Features Used:
Sketch: It is basic command 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 existing faces and bend regions of sheet metal part
Flange: This command is used to add a flat flange at a angle to the planar face and add a bend between the two. A flange consists of bend region and a web.
Closed corner: This command is used to modify two flanges in one operation and to close the corner where the two flanges meet.
Hem flange: This command is used to modify an edge of a sheet metal part by folding it on to itself for the purpose of safe handling or to increase edge stiffness
Mirror Body: This command is used to mirror the 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 flatten sheet material
Bead: This command is used to lift material along contour of a sketch that stimulates a stamping tool. Bead can also be used to stiffen the sheet metal
