Advanced Sheet Metal Design Using NX Cad Challenge_7_ Metal bracket-II

SHEET METAL BRACKET

OBJECTIVE

To design a sheet metal bracket and carryout drafting using Siemens NX.

INTRODUCTION

NX, formerly known as “unigraphics”, is an advanced high-end CAD/CAM/CAE, which has been owned since 2007 by Siemens PLM Software.
Sheet Metal Fabrication is the process of forming parts from a metal sheet by punching, cutting, stamping, and bending.
The thickness of sheet metal starts from 5 mmand goes up to 6 mm. Anything above that is a metal plate. The thin sheet metal is easy to form, while still providing great strength.
Drafting is one of the application in NX Sheet Metal used to get 2-D drawings of all the different views of the designed model.

DESIGN METHODOLOGY

DESCRIPTION

Contour Flange - It is used to extrude a sheet metal surface upto certain distance with a thickness, taking any sketch as reference.

Normal Cutout – This feature is used to make a cutout on the sheet metal part giving appropriate thickness using a sketch.

Break Corner - This feature is used to create a chamfer at the sharp edges in the sheet metal model.

Simple Hole - By drawing points on the sheet metal, taking those points as reference holes are created.

Advance Flange – Flange is created using any edge as a reference. Variable length and angle flanges can be created. Advance flange gives smooth finish at the edge where flange begins.

Rebend - This feature is to rebend the unbent model. This is done by selecting all the bends.

Gusset – Gussets are used to strengthen a flange without the need for secondary processes such as welding.

Flat Pattern - This feature is used to obtain a 2D projection of the flat sheet metal.
