Tolerance and fits ISO description

Calculation of tolerance values for dimensions above 0 and up to 10,000 mm is based on ISO-286-1.

All the calculations in mm.

There is a function for evaluating the fit of the joint in which, according to the specified nominal size value and the selected deviation of the shaft or hole, it is possible to select the fit of the response part with the determination of the gap and tension of the joint, and the size deviation value can be set manually when determining the fit.
The application window "shape tolerances" provides a brief reference description of the deviation of the geometry and the tolerance for parts in accordance with ISO 1101 and ГОСТ 2.308. The values of the tolerances calculated by the application are determined by Russian ГОСТ 24643.
All recent calculations are saved.
