Tolerancing strategies are rarely taught in engineering programs. Designers and engineers are left to fend for themselves, frequently pulling past design practices forward, whether there is a rational basis to do so or not.
Selective Review of GD&T
This advanced three-day course combines tolerancing concepts with statistical methods. We examine part tolerances, fixture tolerances, gage tolerances, assembly tolerances and the interactions between them. Tolerance stacks are evaluated via worst case analysis and a variety of statistical techniques. Strategies for robust design capitalize on operational definitions of GD&T to minimize loss to society.
