Advanced Sheet Metal Design Using NX Cad Challenge_6_Bracket

BRACKET

OBJECTIVE

To model the Bracket using Siemens NX software by sheet metal tool.

INTRODUCTION

The sheet metal can be bent, drawn, cut, punched, or stretched. These processes are responsible for forming the metal into a different shape, surface, or size.

Here, By using Siemens NX Software the sheet metal Bracket is done.

DESIGN METHODOLOGY

FEATURE SEQUENCE/FLOW

MIRROR CURVE

• It is used to make a mirrored copy of sketch geometry through a specified sketch.
• Insert - sketch curve - Mirror curve

CONTOUR FLANGE

• It is used to create a flange by extruding a sketch along a vector, or by sweeping a sketch along an edge or chain of edges. NX adds the contour flange as the base feature of a new sheet metal part, or add the contour flange as a secondary feature.
• Menu - Insert - bend - contour flange

NORMAL CUTOUT

• It cuts the material by projecting a sketch onto the model and then cutting perpendicular to the faces intersected by the projection.
• Insert - cut - Normal cutout.

BREAK CORNER

• It used to round or chamfer sharp corners of a tab or flange.
• Insert - corner - Break corner

UNBEND

• It used to unbend a portion of the part to construct cutout features, hole features, or deform features across a bend.
• Insert - Form - Unbend

BEAD

• It used to lift material along the contour of a sketch that simulates a stamping tool. Beads can also be created to stiffen sheet metal parts.
• Insert - punch - Bead

REBEND

• It is used to reverse an unbend operation so that the feature that was unbent returns to its previous bent state. Any features added after the unbend operation are properly repositioned during the rebend operation.
• Insert - form - rebend

HOLE

• It used to add the following types of hole features in a part or assembly:
• General holes (simple, counterbored, countersunk, or tapered... )
• Drill Size holes
• Screw Clearance holes (simple, counterbored, or countersunk form)
• Threaded holes
• Holes on non-planar faces.
• Insert - Design feature - Hole

FLAT PATTERN

• It is used to create a 2D representation of the flattened 3D sheet metal part.
• Insert - flat pattern - flat pattern
