Robust Tolerance Analysis

Systematic approach to setting targets and tolerances to achieve a specified level of quality at the lowest possible cost.  The process involves:
  • Determining the key outputs and their specifications, the key inputs and their low cost tolerances and the relationship between the inputs and outputs.
  • Find the optimal targets for the low-cost tolerances to achieve a robust design.
  • Determine if the capability meets specified level of quality.
  • If not, determine cause of variation and tighten tolerance.
  • Repeat previous 3 steps until the level of quality is achieved.
