Advanced Sheet Metal Design Using NX Cad Challenge_7_ Metal bracket-II
ADVANCED SHEET METAL DESIGN USING NX CAD -METAL BRACKET DESIGN.
Objective: To design sheet metal part for Metal Bracket as per the procedure by using NX-CAD software with suitable commands on Sheet metal work bench to achieve the final product and also to perform drafting for the Metal bracket.
Introduction: NX CAD software, the digital product development solution from Siemens, includes a set of state-of-the-art tools for designing sheet metal components. Using familiar terminology, NX Sheet Metal Design provides the design professional with a complete set of tools to efficiently create and manage sheet metal parts based on the knowledge of material properties and manufacturing processes.
NX Sheet Metal Design tools incorporate material and bending information, enabling the model to represent both the formed component and flattened blank shapes. The sheet metal design tools within NX allow companies to apply defaults based on both industry and company best practices to the values used in the creation of sheet metal parts. For example, bend radii and neutral factor values can be set to commonly used values to encourage re-use and save design time. Folded and unfolded views of sheet metal components can be used in both the 3D environment, as well as downstream in 2D documentation and for manufacturing.
Design methodology:
Description of Tools used:
SKETCH: It is the 2D representation of the model with respect to the plane or view.
CONTOUR FLANGE: It’s a command is used to make a sheet metal extrusion by using defined sketch as per requirement
NORMAL CUTOUT: It is used to make a cut out using given diagram
BREAK CORNER : Command used for make a fillet at the sharp edge corner sheet metal
UNBEND: Flattens a bend and the material adjacent to the bend.
REBEND: Restores an unbend features to its previous bent state, along with any features added after the unbend feature.
HOLE: Adds a hole to one or more solid bodies in a part or assembly.
GUSSET: A gusset is a thin metal object, typically made of steel, that is used to affix independent members of a structure to each other or to a beam to aid alignment. Gusset plates are used in joint, bend or otherwise disjointed structural locations that require additional support to withstand stresses.
FLAT PATTERN: Flat pattern tool is used to automatically create a flattened version of a sheet metal part and prepare model for manufacturing. The flat pattern feature remains the last feature in the model tree and maintains the flat model view.
TYPES OF VIEWS:
1.TOP VIEW:
2. FRONT VIEW:
3.ISOMETRIC VIEW:
4.SIDE VIEW:
5.FLAT PATTERN:
6.VARIOUS VIEW DRAFT:
7.FLAT PATTERN DRAFT:
CONCLUSION:
Thus, The Sheet metal bracket has been succesfully Designed from NX CAD application using sheet metal tools.
