General Tolerance Iso 2768-mk Here

ISO 2768 Part 1 divides tolerances into four classes: (fine), m (medium), c (coarse), and v (very coarse). The "m" class balances manufacturing cost with functional precision, making it the most common choice for general CNC machining and sheet metal fabrication.

Breakdown of ISO 2768-1: Linear and Angular Dimensions ('m')

Geometrical tolerances control the form, orientation, and location of features relative to one another. Under class , the variations are strictly regulated based on the length of the longest relevant feature. Straightness and Flatness Length of Longest Surface (mm) Tolerance (mm) Over 10 to 30 Over 30 to 100 Over 100 to 300 Over 300 to 1000 Over 1000 to 3000 Perpendicularity general tolerance iso 2768-mk

Features like parallelism and cylindricity do not have explicit tables in Part 2. Instead, they are indirectly governed by other parameters. For example, parallelism is typically controlled by the size tolerance of the linear distance between the two surfaces.

Therefore, indicates that a component must meet Medium linear tolerances and Medium geometrical tolerances . ISO 2768-m Linear Tolerances (Part 1) ISO 2768 Part 1 divides tolerances into four

While Part 1 focuses on size, governs the shape and orientation of features. The "K" class is stricter than "H" but less stringent than "L". The 'K' class applies specifically to:
