Advanced Sheet Metal Design Using NX Cad Challenge_7_ Metal bracket-II

                                                                            METAL BRACKET

Objective: To design and create the given sheet metal component "Metal Bracket" with given dimensions using the various commands in the Siemens NX CAD software.

Introduction:

• The given sheet metal component is an example and for understanding purpose of various tools and features in sheet metal workbench and for practice.

Design methodology:

1. Sketching the shape

2. Construction of base features

3. Creating additional features

4. Unbend and punch features/cutouts

5. Creating flat pattern

6. Draft Analysis

Tools/Features used:

1. Sketch: It creates a sketch in the current application. Use the direct sketch tools to add curves, dimensions, constraints, etc.

2. Circle: This feature creates a circle through three points or by specifying its center and diameter.

3. Profile: It creates a series of connected lines as well as arcs in string mode, that is, the end of the last curve becomes the beginning of the next curve.

4. Contour Flange: It creates a base feature by extruding a sketch along a vector, or adds material by sweeping a sketch along an edge or chain of edges.

5.Normal Cutout: This tool cuts the material by projecting a sketch onto the model and then cutting perpendicular to the faces intersected by the projection.

6. Break Corner: This tool rounds or chamfers a sharp corner of a tab or flange.

7. Unbend: This tool flattens a bend and the material adjacent to the bend.

8. Rebend: It restores an unbend feature to its previous bent state, along with any features added after the unbend feature.

9. Advanced Flange: It adds a flange along an edge using a bend angle or a reference face. The edge and reference face can be curved.

10. Hole: It adds a hole to one or more solid bodies in a part or assembly with options for counterbored, countersunk and threaded.

11. Gusset: This feature creates a stiffening gusset on the part.

12. Drafting: This feature starts the drafting application, which provides tools to create and maintain drawings of the design model.
