Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly

ADVANCED SHEET METAL DESIGN USING NX CAD – BOX

OBJECTIVE

• To know basics of sheet metal module in NX CAD
• To know the basic features like TAB , BEND , FLANGE , REBEND ,BEAD , DIMPLE
• To know the user interface in NX CAD

INTRODUCTION

Metal having thickness from 0.1mm to 6mm are termed as sheet metal. Extremely thin are termed as foils or leaf above 6mm are called as plate. Sheet metal are used in various products used in automobile industry , aeronautical industry. There are many other metals that can be made into sheet metals such as aluminium , copper , stainless steel etc.,

DESIGN METHODOLGY / APPROACH

FEATURES USED

• Tab
• Cut out
• Bend
• Flanges
• Unbend
• Holes
• Dimple
• Bead
• Mirror
• Rebend
• Hem Flange

TAB - TAB is the basic feature in the sheet metal environment in the NX CAD. TAB is the is the initial stage or startup of the sheet metal component. By using the TAB feature we create a base for sheet metal component and can decide the thickness of the sheet metal.

BEND – BEND feature is used to a part of the flat tab into the flange . It uses a sketch that includes bend line . BEND can be created either side of the bend line .

FLANGE –FLANGE feature is used to crate a extended portion or bend to the selected edge. While creating flange we have to set different parameters such as length , Bend radius , inset, bend relief , neutral factor

BREAK CORNER – BREAK CORNER is used to smoothen the harmful corners , we can add radius to it

UNBEND – UNBEND is used to flatten the sheet metal for further design

DIMPLE – DIMPLE is used to lift an area in the model inside the a sketch the simulates a forming tool

HOLE – HOLE is used to create holes in the sheet metal part

BEAD - BEAD is like a raised rib in the sheet metal
