Drawing Sheet Metal Parts

Drawings of sheet metal parts can also contain views of the bent sheet metal part.

Drawing sheet metal parts. As you create flanges and add bends the sheet metal design software will accurately represent the flat pattern required. Sheet metal gauge bend tables store properties for a designated material. For noncircular sheet metal parts the maximum diameter is sometimes used. Drawings of sheet metal parts can also contain views of the bent sheet metal part.

Sheet metal gauge bend table. Thickness is represented by t and d b is the diameter of the blank. You can create dxf files of sheet metal flat patterns without creating a drawing. The flat pattern can be used to document and manufacture associatively as the design changes.

Sheet metal is one of the most versatile materials and processes in the world today. Designers and engineers develop components as small as washers and as large as entire roofs. Products leveraging the possibilities of sheet metal. You can create a configuration in a sheet metal part that shows the flattened part.

When you create a drawing of your sheet metal part a flat pattern is automatically created. It appears in commodity products and in highly specialized one of a kind applications. Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on. Thickness to diameter ratio is a main factor used to quantify the geometry of a blank and can be calculated by t d b.

Bend relief and collars near pierced areas strengthen sheet metal parts. Sheet metal design software considers the fabrication methods needed for manufacturing.
