Sheet Metal Design With Dimensions

The structural type and dimensions are as shown in figure 1 47 and figure 1 48.

Sheet metal design with dimensions.

Sheet metal thickness ranges from 0 024 in. 1220 x 2438 or 1220 x 3048. In a sheet metal design specifying hole sizes locations and their alignment is critical. 48 x 96 or 48 x 120 material dimensions mm.

Specifiers should consider the most economical use of these standard sizes before designing a project. Following all sheet metal design guidelines is very difficult in the complex part. Therefore exceptions can be there for complex features design. This helps in delivering the product at low cost and faster timelines.

Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. 0 609mm to 0 138 in. Because sheet metal parts are manufactured from a single sheet of metal the part must maintain a uniform wall thickness. However in many designs the size of the pre hole is not in accordance with the standard and cannot be accurately positioned.

When designing parts for laser cutting one should not make holes smaller than the thickness of the material. The projection weld nut spot weld nut is widely used in the design of sheet metal parts. It is always better to specify hole diameters that are greater than the sheet s thickness t.
