Calculation method
Calculation method
Assembly nominal (mm)
sum(sensitivity*nominal).
Worst-case half-width (mm)
sum(abs(sensitivity)*halfWidth).
Worst-case minimum (mm)
nominal-halfWidth.
Worst-case maximum (mm)
nominal+halfWidth.

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Calculation steps and notation
sum(list) adds all entries in the list.
Assumptions & limits
Assumptions & limits
- Linear signed dimensional chain with independent interval bounds; no assembly compliance or geometric datum model. Supported limits: 1..100 rows; finite sensitivities and nominals; tolerances>=0.
