Advanced Sheet Metal Design Using NX Cad Challenge_1_Casing Design
Objective- To design a sheet-metal casing component 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. Also attach the Final model Images.
Introduction- What Is Sheet Metal?
Sheet metal is one of the shapes and forms metal can be bought in. Sheet metal is any metal that has a thickness in between 0.5…6 millimetres.
Sheet Metal Casing or an enclosure is a sheet metal component which is used in various applications such as in auto mobiles and electrical components to place the various circuits or switches in a computer CPU system or wire harnesses and it also provide protection of the components which are present inside the casing.
Design Methodology- The design approach which is used to design the component is mentioned below with the help of a flow chart
Sketch - It is the basic of any design on which the boss features are extruded or padded.
Tab - Tab is a command used to create a base for any sheet metal part that can be extruded from a sketch. The sketching plane can be selected as per the designer’s choice.
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. The angle, width, length, and type of flange can be determined as per the requirements.
Unbend - This feature is used to unbend the adjacent bends and flatten them. Here it is used to create more features. This command is used to unbend the sheet metal parts to create geometries and work on complicated designs. In this command, we have to select a stationary face and then select the corners of flanges to unbend.
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. The selected sketch is lifted off from the base to provide strength to the material. Similar to dimple, the material can be removed in both directions.
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. Here six simple holes are created on the unbent surface with a diameter of 10mm. It can be used to make customized or standardized holes along with a defined point or path. The depth of the hole can be controlled.
Flat pattern - It creates a flat pattern feature from the formed sheet metal part. The user chooses this command to create a flat view of the sheet metal after unbending all the sides and faces. This view can be used in drawing the flat pattern along with the bend radius and other dimensions.
