Sheet Metal Tolerance Chart

Iso 2768 tolerance chart oem metal parts.

Sheet metal tolerance chart.

General tolerances to din iso 2768. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. The information within this table is based on tertiary sources original research particular assumptions and calculations. General tolerance iso 2768 does not specify where to use these tolerances.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. As per design requirements and manufacturing capability tolerance class is defined. The latest din standard sheet version applies to all parts made to din standards. The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the manufacturer s standard gauge which has no inherent tolerances.

Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered. For sheet metal parts iso 27 68 mk is used. Sheet metal is metal formed by an industrial process into thin flat pieces. And for machined components iso 27 68 fh can be used.

Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes countless everyday objects are fabricated from sheet metal. Sheet metal guage tolerances. Additionally minor variations between data sources. This chart shows suggested tolerances.

Sheet metal tol tolerance table description. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
