Sheet Metal Stamping & Press Lines worked example

Die Life Cost at 58% usable die-life fraction realized: a worked example in sheet metal stamping & press lines

Suppose usable die-life fraction realized falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Die Life Cost captures the tooling dollars that wear into every stamped part — sharpening, insert replacement and amortized die build — adjusted for how much of the expected die life you actually realize before a refurbish.

The inputs for this scenario

  • Parts run before die refurb: 100 units (held at the documented default)
  • Tooling & sharpening cost per part: 45 $ / unit (held at the documented default)
  • Usable die-life fraction realized: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed die build/amortization cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Die Life Cost cost = quantity × rate × capture factor + fixed cost.
  • Weighted cost works out to 2,860 $ at these inputs, and this is the headline figure for the scenario.
  • Per piece value works out to 28.6 $ / piece at these inputs.
  • Captured value works out to 2,610 $ at these inputs.
  • Fixed adjustment works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where usable die-life fraction realized sits at 80% and the headline result is 3,850 $, this scenario comes in 25.71% below the baseline at 2,860 $.
  • It computes total die-related cost as parts times per-part tooling cost times the realized-life factor plus fixed die cost, then divides by parts for per-piece die cost. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
