In mechanical engineering and manufacturing, specifying precise tolerances for every single dimension on a technical drawing can be incredibly time-consuming and clutter the document. The provides a simplified solution to this problem by setting general, internationally recognized tolerances. Among these, ISO 2768-mK is one of the most commonly used standards in CNC machining, injection molding, and metal fabrication.
