James D. Meadows provides a comprehensive, mathematically reliable methodology for tolerance stack-up analysis, bridging theoretical design with practical manufacturing, assembly, and inspection requirements. His approach utilizes loop analysis and number charting to optimize tolerances using both worst-case and statistical methods based on ASME standards.
