In the world of sheet metal fabrication, precision and consistency are non-negotiable. When ordering stamped or formed components, engineers and buyers rely on standards to ensure that parts meet specific geometric and dimensional requirements. One such critical standard is DIN 6930-f .
is a German (Deutsches Institut für Normung) standard that specifies permissible deviations for dimensions and form for stamped and formed parts made of sheet metal .
If you work with press brakes, stamping presses, or laser-cut blanks that will be bent into shape, this standard likely applies to your technical drawings. Here is everything you need to know about DIN 6930-f. Before diving into the "-f" specifically, let's look at the parent standard.
When in doubt, start with DIN 6930-m (medium) and tighten to "-f" only on critical dimensions or through specific notes on the drawing. Need to look up the exact numerical table? Refer to the official DIN 6930-1:2011 and DIN 6930-2:2011 standards. Your local standards body (e.g., Beuth Verlag for Germany) provides the complete documents.
