Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly
Designing of a sheetmetal Box Assembly
Objective: To design a ‘Sheetmetal Box Assembly’ using Siemens NX Sheetmetal Application.
Introduction: For studying different tools and features used for designing sheet metal design parts, this project was selected. This project was mainly focused in providing an idea about the workflow in creating a part design and to familiarize certain tools in this application.
Design Methodology:
As shown in the flowchart, I started by sketching the base feature and it was constructed by using the tab feature. Then certain additional features like bends and flanges were added to the base feature. Then after that certain feature like closed corners, hem flanges, beads and dimples were applied on the base feature. Then it was unbended and rebended and a flat pattern was applied for creating a draft image.
Description:
For designing of a Sheetmetal Box Assembly the following features were used:
- Tab: This tool was used to create a base feature by extruding the sketch along a direction by thickness value.
- Bend: To create a bend specified to an edge or sketch input.
- Flange: This is used to add a flange at any angle to a planar face producing a bend between the two faces.
- Hem Flange: To create a hem like flange in the edges.
- Break corner: To round the sharp edges of tabs and flanges.
- Closed Corner: To close two adjacent flange corners.
- Dimple: Is used to lift an area of the model based on the input sketch.
- Bead: To lift material along the contour of the sketch.
- Mirror: To pattern features along plane.
- Unbend: To flatten the bend features.
- Normal Cut-out: To create a cut based on the sketch input.
- Rebend: The unbended features are bended using this feature.
- Flat Pattern: Used to create a flat pattern for draft purposes.
