Advanced Sheet Metal Design Using NX Cad Challenge_2_Box Assembly
Box Assembly
Objective
To design a sheet-metal Box Assembly with the use of NX-CAD Software and Write a detailed report on Sheet Metal Component with good explanation on Sheet Metal modelling tools applied throughout the modelling.
Introduction
The term “sheet metal” refers to any metal that can be formed into flat pieces of varying thicknesses. Thick metals are called plate. Metals used in the sheet metal industry include cold rolled steel, mild steel, stainless steel, tin, nickel, titanium, aluminum, brass, and copper.
Sheet Metal Box is a sheet metal component acts as a casing for various auto components, electrical components etc.
Design Methodogy
Tab - Tab is a command used to create a base for any sheet metal part that can be extruded from a sketch.
Flange - It is used to create an extended part (bend) of a sheet metal. It is created at the edge of one side of the model. This command will allow us to select the edge of the base to create a projecting flat extruded surface.
Unbend - This feature is used to unbend the adjacent bends and flatten them.
Rebend - It is used to re-bend the corners that were bent before along with any features added after the unbend feature.
Bead - It lifts material along the contour of a sketch that simulates a stamping tool, it is used for giving strength to the sheet metal. Here two beads are created on the unbent surface.
Hem - This command is used to modify an edge of a sheetmetal part by folding it on to itself for the purpose safe handling or to increase edge stiffness.
Mirror Body - This command is used to mirror the part w.r.t the required axis.
Unite- This command is used to combine the two parts into a single part .
Dimple: Lifts an area of the model inside a sketch that simulates stamping a tool.
Hole - It adds a hole to one or more solid bodies in a part or an assembly with options for counterbored, countersunk and threaded.
