Tolerance Mechanical Calculator

Performs calculations of closed linear dimension chains within individual parts or in assemblies.

Dimension chains consist of individual elements, such as dimensions and spacings between individual parts (free play). Individual chain elements can be increasing, decreasing, or closing. Closing elements are parameters formed at the time of assembly of the given part (assembly-resultant elements, such as free play), or during the production process (production-resultant elements).

The application can work in the following two basic modes:

• Calculation of the resulting dimension including tolerances (check calculation): performs a check verifying correctness of designed dimensions.
• Calculation of tolerances of the closing chain element (design calculation).

Tip: See the Tolerance Calculation Formulas topic for used calculation formulas and other instructions for calculation tolerances.
