Report: General Tolerances per ISO 2768-mK
Date: October 26, 2023 Subject: Interpretation and Application of General Tolerance Standard ISO 2768-mK
The "K" class defines general limits for the form and position of features. For example, surfaces with fitting dimensions must remain flat and parallel within the specified K-class range to ensure assembly functionality. 4. Technical Advantages general tolerance iso 2768-mk
The designation "mK" combines two specific parts of the standard: "m" (Medium) : Refers to ISO 2768-1 , covering linear and angular dimensions. "K" (Medium) : Refers to ISO 2768-2 Report: General Tolerances per ISO 2768-mK Date: October
1. Executive Summary
ISO 2768 is an international standard that simplifies engineering drawings by providing standard tolerance values for linear and geometric dimensions. This eliminates the need to specify tolerances for every single dimension on a drawing. Approved by: Cost Efficiency: Tighter tolerances (like ISO
- m = 1.0°, k = 3.0°
Approved by:
Cost Efficiency: Tighter tolerances (like ISO 2768-f) can be 2 to 2.5 times harder and more expensive to machine. The "mK" class offers a sweet spot between precision and production speed.
