Advanced Sheet Metal Design Using NX Cad Challenge_7_ Metal bracket-II
ADVANCED SHEET METAL DESIGN USING NX CAD - METAL BRACKET II
OBJECTIVE
The objective of this project is to create a metal bracket in Siemens NX using the sheet metal tool and to create a draft of the sheet metal casing in NX.
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. Thicknesses can vary significantly. Sheet Metal application provides an environment for the design of sheet metal parts used in machinery, enclosures, brackets, and other parts normally manufactured with a brake press.
- Siemens NX sheet metal design software incorporates material and process information in sheet metal-specific modelling features: bends, flanges, tabs, cutouts, beads, dimples, louvres, corner and edge treatments, patterns, and other formable features.
- You can also quickly convert solid models to sheet metal components, and create sheet metal parts that enclose other components. More than 85% of Sheet metal industries use NX CAD as a design tool.
DESIGN METHODOLOGY
SKETCH > CONTOUR FLANGE >BREAK CORNERS > NORMAL CUTOUT > UNBEND > REBEND > ADVANCED FLANGE > HOLES > GUSSET > DRAFTING.
DESCRIPTION
Sketch - It is a basic and initial operation for creating any kind of sheet metal components.
Normal cutout - It cuts the material perpendicular to the sketch.
Bend - It is used for bending the material on one side of a sketch line by adding a bend between two sides.
Contour flange - It creates main flange or second flange by extruding sketch in sheet metal application.
Advanced flange - It adds flange along the edge using the reference face or bend angle.
Break corner - It Rounds a sharp corner at edges. It avoids sharp edges by making it smooth.
Unbend - It flattens a bend and material adjacent to the bend.
Hole - It creates a whole on basis of circle created.
Rebend - It restores a bend.
Drafting - It is used to draw 2D drawing from a 3D model. The drawing shows dimensions, relations, annotations etc. which is used to manufacture the components.
