What Output Do I Get at the Conclusion of Empirical Tolerance Design? What Are Key Deliverables from Empirical Tolerance Design from its Application in the Roadmaps?

• Optimized critical functional parameter set points that control subsystem and subassembly contributions to system level functional and assembly variation

• Optimized critical adjustment parameter tolerances used to tune the mean value of the system, subsystem, and subassembly critical functional response(s)

• Optimized critical-to-function specification set points that control component contributions to functional and assembly variation

• Critical Parameter Management data that is documented in the CPM relational database:

  System level variance models

  Subsystem level variance models

  Subassembly level variance models

  Component level variance models

  Manufacturing process level variance models

  CFP tolerances and their percentage contribution to CFR variation

  CAP tolerances and their percentage contribution to CFR variation

  CTF spec tolerances and their percentage contribution to CFR variation
