Norme Iso 2768 Mk _hot_ -

By invoking ISO 2768-mK, the designer communicates that all dimensions without specific tolerances must comply with the “medium” linear and “K” geometric limits. This drastically simplifies the drawing, reduces clerical errors, and streamlines the first-article inspection report. For the workshop, it signals a standard of good practice: the part must be reasonably flat, holes must be reasonably perpendicular to faces, and linear sizes must fall within typical milling or turning accuracy without secondary operations.

The "m" stands for . It is the most commonly used tolerance class for general machining. It represents a balance between manufacturing cost and precision. norme iso 2768 mk

However, ISO 2768-mK is not a universal panacea. It is explicitly not intended for certain features. The standard excludes tolerances for chamfer angularity, fillet radii, or dimensions that are inherently dependent on other features (e.g., angular relationships from a datum). Furthermore, “mK” is inadequate for high-precision industries like aerospace or medical devices, where finer classes (like ISO 2768-fH) or fully defined individual tolerances are mandatory. By invoking ISO 2768-mK, the designer communicates that

It was a typical Monday morning at the factory of Precise Engineering, a leading manufacturer of high-quality machinery parts. The production team was buzzing with activity as they prepared for another busy day. Among them was Jérôme, a seasoned quality control engineer, who was responsible for ensuring that all products met the company's stringent quality standards. The "m" stands for

For any organization developing mechanical parts, referencing ISO 2768-mK in the title block is industry best practice for non-critical features, ensuring a balance between manufacturing speed and component quality.
