Advanced Sheet Metal Design Using NX Cad Challenge_6_Bracket
Bracket Using NX CAD
Objective:
The main objective of this project is to design the bracket from 2D drawing using NX CAD using sheet metal application.
Introduction:
The bracket design is done with the inputs from the 2D drawing. The design is completed by using some basic option which is available in the sheet metal application workbench. The commands used for this design contour flange, normal cut-out, break corner, beads, hole, unbend and rebend.
Design Methodology:
Description:
Sketch Creation:
The front view sketch is created in the XY plane.
Contour Flange:
After sketch creation, the contour flange feature is used to create the base feature. Contour Flange is 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.
Normal Cut-out:
The sketch is created in the XY plane and the normal cut operation is done to remove the material. Normal cut-out is the command that cuts the material by projecting a sketch into the model and then cutting perpendicular to the faces intersecting by the projection.
Break Corner:
After the cut-out operation, the sharp edges are blended by the command rounds or chamfer the sharp corner of a tab or flange.
Create Bead:
For creating the bead, sketch is drawn as per the dimension after unbending the sheet metal, since bead is present in the bending surface.
Bead:
This command lifts the material along the contour of a sketch that stimulate a stamping tool. The depth is given as per the drawing and the local radius is measured after rebinding the sheet metal.
Hole Creation:
The sketch is drawn as per the dimension for the hole creation. Then the simple through hole is used to make the holes. The distance between the holes is measured and captured using measuring distance command available in the analysis tab.
Different Views of Sheet Metal Casing:
1.Front View:
2.Top View:
3.Side View:
4.Isometric View:
Conclusion:
Designing a bracket with the sheet metal guidelines has given a very good approach to various tools of Siemens NX that really helpful with saving time, easy to apply and update. Objectives of this project are achieved with desired result.
