Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly
Designing of Box Assembly
OBJECTIVE:
Design a Box_Aseembly using NX Cad software with suitable commends to achieve the final modeling as per the inputs.
INTRODUCTION:
Sheet metal is metal formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Countless everyday objects are fabricated from sheet metal.
Applications: Aircraft bodies, Automobile bodies, Utensils used for domestic purposes, Beverage Cans.
The Sheetmetal Application provides an environment for the design of sheetmetal parts used in Machinery, Automotive, Aerospace, etc.
By using Sheetmetal Application We can do:
• Import, clean up and convert 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 a 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 sheetmetal parts.
Flange: This command is used to add a flat flange at an angle to the planar face and add a bend between the two. A flange consists of a 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 sheetmetal part by folding it onto itself for the purpose of 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 another 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 the contour of a sketch that stimulates a stamping tool. Bead can also be created to stiffen sheet material.
Datum Plane: This feature is used to project the plane at a certain distance by giving the distance.
Normal Cutout: This command is used to remove the unwanted material w.r.t to the sketch.
Break Corner: This command is used to round or chamfer sharp corners of a tab or flange.
