2.3 Tolerance Analysis & Dimensional Engineering:

Tolerance analysis and dimensional engineering are vital for guaranteeing that all module components will fit together correctly during assembly. Designers perform tolerance stack-up analyses, often using specialized CAD software modules, to understand how the variations in individual part dimensions can accumulate. This activity involves defining critical dimensions and applying Geometric Dimensioning and Tolerancing (GD&T) on engineering drawings to precisely communicate design intent and acceptable manufacturing variability. Close collaboration with manufacturing teams is essential to understand process capabilities and ensure the design is producible within the specified tolerances.
