Advanced Sheet Metal Design Using NX Cad - Sheet Metal Box Assembly
Sheet Metal Box Assembly
Objective
Design a Sheet Metal Box assembly in Seimens NX application.
Introduction
Sheet Metal Boxes are widely used in storage applications like lockers for jewels, storing tools, in automotive, covering machines etc. Commonly used materials are steel and aluminum. They are manufactured using some automated machines, where they can be cut, folded, bended, stamped or punched.
Design Methodology

Description
Tab: Use this command to create a base feature by extruding a sketch along a vector by a thickness.
Normal cutout: Use this command to make a hole or cutout using a sketch on the sheet metal.
Bend: It modify the model by bending material on one side of a sketch line.
Flange: Using this command we can add flange. Flange consist of bend and web region.
Break corner: It provides chamfer or blend to the sharp corners.
Unbend: It will flatten the bend region.
Rebend: After unbend the rebend command will bend the bend region to its original form.
Dimple: Dimple is a punch operation. It creates a depression on the surface.
Bead: It is also a punch function, used to stiffen the surface.
Hem: it modify the model by folding the edge of flange, for the purpose of safe handling and to improve stiffness.
