Iso 2768 Mk |verified| -

Class 'm' is intended for parts produced by common machining processes such as turning, milling, or drilling where average accuracy is expected. It assumes standard workshop conditions without the need for special finishing operations like grinding or honing.

The most common standard for general engineering and CNC machining. c (Coarse): For parts where high precision is not critical. v (Very Coarse): Used for rough manufacturing processes. 2. The "K" (ISO 2768-2): Geometrical Tolerances ıso 2768 mk

When a drawing references "ISO 2768-mK," it implies that any dimension or geometric feature not explicitly tagged with a specific tolerance falls under these "general" rules. This significantly de-clutters the drawing, highlighting only those features requiring precise control. Class 'm' is intended for parts produced by

Angular dimensions (e.g., 45° chamfer): ±1° for the "m" class. c (Coarse): For parts where high precision is not critical

Symmetry and runout: For class K, general symmetry tolerance equals the flatness/perpendicularity value, and circular runout is 0.1 mm.
