Calculation basis

  • Annualized machine and tooling:
  • Annual rivet consumption:
  • Labor, maintenance, downtime and reject/rework:
  • Accepted joints: attempted joints × (1 − reject rate)

This Bronze-level planning framework depends entirely on the values entered. It does not predict joint quality, final throughput or payback; validate those with sample joints and a defined acceptance test.
