Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design

TITLE : sheetmetal casing design

OBJECTIVE : TO design the "sheetmetal casing design" using nx cad application

INTRODUCTION :

sheet metal designing is an indestrial processes like bending,punching ,deep drawing etc. in to thin flat picees

sheet metal designing is used in various industries like automobile,aeronautics,medical tables,beverages cans,etc.

here, we are using cad model of sheet metal casing in NX CAD software.sheet metal work bench is used to create this cad model. design methodology used to create this sheet metal casing design described below

Approch:

Discription:

1)SKETCH:

using 2d sketch command create 2d wireframe and exit the sketch

sketch is the basic feature to create any sheet metal design.

2)TAB:

using tab feature create the base of the casing by selecting the 2d curve

3)Normal cutout:

using this feature we can cut the specific portion of the tab by sketching

the required dimensions

4)Bend:

using this feature we can bend the tab at any specific length and angle

5)Flang:

using this feature we can create flang to a base feature. to create a flang just select the any edge base

6)Break corners:

this feature is used to remove the sharp edges and used to create blend or chamfer with specific radius

7)UNbend and rebend:

this tool is used to flattend the sheet metal part to create complex structure over it and we can rebend it again after the operation completed

8)Holes:

holes are ceated for fitting purpose with various sizes and types

9)dimple:

it is a punch tool used to create emboss over the sheet metal part to give strengthen the part locally

10)bead:

it is a another tool of punch used to create a emboss with required shape and specific size

11)mirror:

this feature is used to create copy of feature like bead,cutout etc. over the sheet metal part to reduce the time and process, effort

Final model of sheetmetal casing design:

1)front view

2)top view:

3)side view:

4)isometric view:

Drawing sheet:

conclusion:

in this challenge i learned the basics of sheet metal designing. using features like tab,flang,bend,punch tools,etc.
