How do you calculate machining tolerance?
The following terms are often used when applying tolerances:
- Basic size: The diameter of the bolt, or shaft, and the hole.
- Upper deviation: The difference between the part’s maximum possible size and basic size.
- Lower deviation: The difference between the part’s minimum possible size and basic size.
What is the purpose of DIN ISO 2768?
ISO 2768 and derivative geometrical tolerance standards are intended to simplify drawing specifications for mechanical tolerances. ISO 2768 is mainly for parts that are manufactured by way of machining or removal of materials.

What is ISO tolerance?
ISO Tolerances (DIN ISO 286-1) All International Tolerance Grades (IT-Grades) and fundamental dimensions are considered. The app “ISO Tolerances” is a fit calculator and addressed to students, employees and apprentices (trainees) in all technical sectors. It calculates all information about a fit by entering a basic size in a matter of seconds.
