Drawing Sheet Metal Parts

Sheet metal is one of the most versatile materials and processes in the world today.

Drawing sheet metal parts.

Thickness to diameter ratio is a main factor used to quantify the geometry of a blank and can be calculated by t d b. Designers and engineers develop components as small as washers and as large as entire roofs. As you create flanges and add bends the sheet metal design software will accurately represent the flat pattern required. Drawings of sheet metal parts can also contain views of the bent sheet metal part.

Sheet metal design software considers the fabrication methods needed for manufacturing. Sheet metal gauge bend tables store properties for a designated material. Thickness is represented by t and d b is the diameter of the blank. The flat pattern can be used to document and manufacture associatively as the design changes.

For noncircular sheet metal parts the maximum diameter is sometimes used. Sheet metal thickness is an important aspect of deep drawing process design. Drawings of sheet metal parts can also contain views of the bent sheet metal part. You can create dxf files of sheet metal flat patterns without creating a drawing.

You can create a configuration in a sheet metal part that shows the flattened part. Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on. When you create a drawing of your sheet metal part a flat pattern is automatically created. Sheet metal gauge bend table.

It appears in commodity products and in highly specialized one of a kind applications. Bend relief and collars near pierced areas strengthen sheet metal parts.
