Final Verdict

5. Practical Implications and Recommendations

Use these values for calculations.

• "m" (medium): Applies to linear and angular dimensions.
• "K": Applies to geometric form and position tolerances.

. It simplifies drawings by removing the need to label every single measurement, ensuring that the "default" precision of a part is understood by the machinist. The code is divided into two parts: : Refers to general tolerance iso 2768-mk

• Add note: “ISO 2768‑1 m” or “ISO 2768‑1 m; ISO 2768‑2 m” (or simply “ISO 2768‑m”) depending on parts used.
• Prefer explicit: “Tolerances unspecified: ISO 2768‑1 (linear and angular) — class m; ISO 2768‑2 (geometrical) — class m.”
• Do not mix with specific tolerances; specific dimensions override general note.
