Of course exceptions apply. As the largest stamping and spring company in northern california scandic is the leading source for custom metal parts. This can lead to formed parts looking different than the models they are based on.

General tolerance iso 2768 does not specify where to use these tolerances. It applies to the dimensions of parts that are produced by metal removal or parts that are formed from sheet metal. Flatness tolerances for sheet are published only for full size sheets. For sheet metal parts iso 2768 mk is used.

Plates can be out of flat for a number of reasons. General dimension tolerances of punching units. Was a hot critical job talk about close tolerance. Steel bar sheet strip tube etc sheet metal fabricators sheet metal work manufacturers.

When designing parts with some type of bend with a standard bend radius sheet metal tolerances are required to open. Steel bar sheet strip tube etc steel processing glass stained leaded commercial 619 750 2993. And for machined components iso 2768 fh can be used. Engineers designing sheet metal parts should understand the importance of bend relief and how it helps avoid torn.
