Iso 2768-mh Tolerance Chart 2021

To interpret the ISO 2768-MH tolerance chart, follow these steps:

GENERAL TOLERANCES ISO 2768-mH

ISO 2768‑2 provides default values for geometrical tolerances when such symbols are omitted, but it is safer to specify geometric controls directly when required. iso 2768-mh tolerance chart

Fixed at a maximum of 0.5mm for all ranges in class H. Application and Benefits General Tolerance - ISO 2768 1 & 2 - ZEISS Quality Forum A 5mm chamfer callout with no tolerance is allowed to be 4

Tolerances for angles when no individual tolerance is given.

A 5mm chamfer callout with no tolerance is allowed to be 4.5mm to 5.5mm. That is a massive 20% variation. If you need a cosmetic 45° x 1.5mm chamfer, you must explicitly tolerance it as max 1.6mm/ min 1.4mm.
