Advanced Sheet Metal Design Using NX Cad Challenge_6_Bracket
DESIGN AND MODELLING OF SHEET METAL BRACKET BY USING IN NX-12
OBJECTIVE :
To design and model the sheet metal bracket in nx-12 by using some basic feature and tools.
To learn how to design a sheet metal bracket from a given drawing .
To master the user interface and basic feature of sheet metal application in nx-12 like contour flanges, normal cutout ,break corner , unbend ,bead, re bend and hole.
INTRODUCTION :
Sheet metal design and fabrication
sheet metal fabrication is the process of forming part from a metal sheet by punching , cutting ,stamping, and bending.
3d cad files are converted into machine code ,which control a machine to precisely cut and forms the sheet into final part .
Sheet metal part are known for their durability ,which makes them great for end use application .part used for low volume
Prototypes and high volume production runs are most cost- effective due to large initial setup and material coasts.
Because part are formed from a single sheet of metal ,design must maintain a uniform thickness.be sure to follow the design requirement
And tolerance to ensure parts fall closer to design intent and cutting sheets of the metals .
DESIGN METHODOLOGY /APPROACH
DESCRIPTION
Tool / feature used while desiging the sheet metal bracket.
1 contour flange - in siemens nx sheet metal contour flange command used to create a base feature by extruding a sketch along
a vector or adds material by sweeping a sketch along an edge or chain of edge.
2 normal cutout-normal cutout command extract volume from sheet metal production principle .cutting face will be perpendicular to the sheet metal surface
3 breaK corner - this feature is used to smoothen the harmful corner of the sheet or to give an attractive look to the part
4 un bend : this feature is used to flatten the sheet metal part for further design operation
5 Bead - the bead is like a raised rib in the sheet metal panel. It requires that you have a least one sheet metal panel
In the active part as well as an open or closed -loop sketch.
The bead is another feature that has only a button for option on the command bar.
6 rebend- rebend feature is used to get the original bend shape after performing forming operation like a dimple ,bead.
7 hole- this feature adds holes to sheet metal part.
8 flat pattern - this feature is used to create an instance of the flat shape and size of the sheet metal that required to create the final part
drawing
conclusion :
sheet metal bracket is designed sucessfully in the nx-12 sheet metal environment.
basic features of the sheet metal environment of nx-12 like creating a sketch , contour ,flange ,normal cutout,break corner, unbend ,bead ,rebend,and hole and the flat pattern are learned and applied in design .
