Tolerances

Limit DimensionsCalculates maximum and minimum limits from a nominal and signed deviations.

ISO Tolerance GradesDisplays the width of international tolerance grades for a nominal size up to 500 mm.

Conformity with Measurement UncertaintyCompares the full measurement uncertainty interval against specification limits.

Gauge R&R Type 1Calculates repeatability and systematic bias of a gauge against a reference part.

Measurement Uncertainty BudgetCombines independent components of a length measurement into standard and expanded uncertainty.

Surface RoughnessCompares an Ra value with historical N classes and a user-selected Rz estimate.

Fit FinderFilters the stored preferred fits by desired clearance range.

Fit per ISO 286Calculates limits of deviation, limit dimensions, clearance or interference, and fit type from nominal size, hole, and shaft tolerance zones.

Press FitEstimates the elastic contact pressure and friction-transmittable load of a cylindrical press fit.

Process Capability Cp and CpkCompares measurement data against specification limits and separates short-term from total variation.

Acceptance Sampling and RiskCalculates acceptance probabilities of a user-defined sampling plan under the binomial model.

Tolerance AllocationDistributes a closure tolerance equally across independent dimensions.

Tolerance StackCalculates worst-case and statistical variation of a linear dimension chain.
