Advanced Sheet Metal Design Using NX Cad

Odd Shaped Enclosure

Introduction

In this project, we are to learn to design Odd Shaped Enclosure using NX Cad for modeling. Siemens NX is cutting-edge software that is highly useful for the manufacturing sector. It provides many applications like sheet modeling and modeling and drafting.

NX Sheet Metal contains a powerful set of tools to design and optimize sheet metal parts. Standard bending calculations, sheet metal features, and advanced analysis tools all contribute to improving quality and reducing the cost of sheet metal parts.

NX Sheet Metal provides a set of tools within the NX design environment that allows for simple and fast design of sheet metal parts, dependent on their material and manufacturing process, the most common of which is straight brake sheet metal forming.

In Odd Shaped Enclosure Designing, NX sheet metal tools like flanges, Sheet metal from Solid, Jog, Bead, etc to get the final model. The drafting tool is used to get the technical sketch of the model made.

2.Tools / Features Used

1. Extrude: This tool helps to form solid from the sketch made.
2. Sheet Metal from Solid: It helps to form sheet metal wrapping a solid model with the help of selected faces.
3. Unbend: It helps to unfold the model surfaces and exhibit all surfaces to a plane. It flattens the bend.
4. Flange: Flanges are used to create a bend between two walls. The flange can only be made on a straight edge. It can be bent at any angle in different directions.
5. Jog: It helps to lift material from the surface forming a flange between them.
6. Hole: To create incisions on the surface based on the requirement. Closed sketches are made on the surface to create holes.
7. Bead: Lifts material from the surface based on the sketch we provide. The sketch is stamped on the surface of sheet metal.
8. Rebend: It helps to fold back the surfaces as they were. Bend and Rebend are the opposite tools that help in unfolding and folding surfaces.
9. Flat pattern: Creates flat pattern features from formed sheet metal. Creating a flat solid allows the designer to quickly get a flattened model of the bent sheet metal part. This tool can be extremely useful to measure the total area of the sheet metal required for the component.
10. Draft: After completing the final model drafting helps to get a technical drawing of the component at ratio.

Design Process

1. A solid body is created using the extrude feature in the sketch made in the XZ plane.
2. Sheet metal from solid features is used to create a sheet metal wrapping the solid created.
3. The flange is made on one side of the sheet metal and Jog on the other side.
4. Then the sheet metal is unbent to create holes, and beads on it.
5. Then sheet metal is bent back using rebend.
6. A flat pattern feature is applied and a draft of the sheet metal is created as per different views.
