The use of general tolerance ISO 2768-MK has several benefits, including:
Or more explicitly:
Beginners assume that a 500 mm long part can have multiple 0.5 mm deviations. ISO 2768 tolerances are not cumulative over multiple features. Each dimension is measured directly between the two specified points. general tolerance iso 2768-mk
The designation "" combines two specific precision levels: The use of general tolerance ISO 2768-MK has
ISO 2768-MK is a standard published by the International Organization for Standardization (ISO) that defines the general tolerances for linear and angular dimensions. The standard provides a set of tolerance limits that can be applied to parts and components to ensure that they are manufactured within acceptable limits. The designation "" combines two specific precision levels:
To apply this standard correctly, you need the exact tolerance ranges. Below are the critical tables derived from the standard.
In the world of technical drawing and mechanical engineering, specifying every single dimension with a unique tolerance is impractical, time-consuming, and often redundant. This is where come into play. Among the most frequently referenced standards worldwide is ISO 2768 . While many are familiar with its basic forms (ISO 2768-1 for linear and angular dimensions), the specific variant ISO 2768-mK is arguably the most widely used—and most misunderstood—tolerance class in modern manufacturing.
