Every tool runs a deterministic SI engine with selectable universal units and reference-standard values on every input, three-tier validation with a production verdict, and an integrated Audit/Review module — inputs, formulas, assumptions, warnings, engine version and integrity hash in every report.
Omni-search across every calculator by task, sector or standard — with categories for machining, rotating equipment, tolerances, welding, lifting, pressure equipment, fasteners and costing.
Extended Taylor tool life with coolant/interruption correction, chip-thinning & HEM engagement compensation, Kienzle force, power/torque verification, deflection, surface finish and Gilbert minimum-cost optimization.
L10 and modified rating life Lnm with digitized ISO 281 aISO equations (κ, eC·Cu/P), viscosity-ratio analysis, X/Y equivalent-load interpolation, static safety and life-margin verdict.
