Products > Tolerances and deviations

This workbook includes tables and calculations for easy option of fits of machine parts and determination of their dimensional tolerances and deviations. Using this tool the following tasks can be solved:

Selection of suitable fits of machine parts according to the international standard ISO 286.
Determination of dimensional tolerances and deviations of machine parts according to the international standard ISO 286.
Selection of preferred fits of machine parts and determination of their dimensional tolerances and deviations according to ANSI B4.1.
Determination of non-prescribed limit deviations of linear and angular dimensions according to ISO 2768.
Automatic design of a fit for the given clearance or fit interference respectively.

The data, procedures, algorithms and specialized literature and standards ANSI, ISO, DIN and others were used in the calculations.

List of standards: ANSI B4.1, ANSI B4.2, ISO 286, ISO 1829, ISO 2768, EN 20286, JIS B 0401
