Mk Pdf - Tolerance Iso 2768

This section defines the permissible deviations for dimensions like lengths, diameters, and external radii. The "m" (medium) class is the most common for standard industrial machining. Table 1: Linear Dimensions (Permissible deviations in mm) Nominal Range (mm) Class f (fine) Class m (medium) Class c (coarse) ±0.05plus or minus 0.05 ±0.1plus or minus 0.1 ±0.2plus or minus 0.2 Over 3 to 6 ±0.05plus or minus 0.05 ±0.1plus or minus 0.1 ±0.3plus or minus 0.3 Over 6 to 30 ±0.1plus or minus 0.1 ±0.2plus or minus 0.2 ±0.5plus or minus 0.5 Over 30 to 120 ±0.15plus or minus 0.15 ±0.3plus or minus 0.3 ±0.8plus or minus 0.8 Over 120 to 400 ±0.2plus or minus 0.2 ±0.5plus or minus 0.5 ±1.2plus or minus 1.2 Over 400 to 1000 ±0.3plus or minus 0.3 ±0.8plus or minus 0.8 ±2.0plus or minus 2.0 ISO 2768-2: Geometrical Tolerances (Class K)

If a designer explicitly specifies a tight tolerance (e.g., $\pm 0.01$ mm) where it isn't needed, the machinist must use more expensive tools, slower machine speeds, or extensive inspection processes to meet it. If a designer explicitly specifies a tight tolerance (e
