Tooling Wear Cost at 65% wear-life consumed: a worked example

This worked example runs the tooling wear cost numbers for a tougher week than the baseline: 65% wear-life consumed instead of the typical 90%. Estimate die and punch wear cost attributable to a stamping or micro-forming run.

The inputs for this scenario

  • Parts stamped this run: 50,000 parts (held at the documented default)
  • Tool wear cost per part: 0.01 $/part (held at the documented default)
  • Wear-life consumed: 65 % (the input this scenario stresses; the baseline uses 90)
  • Sharpening setup charge: 220 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Tooling wear cost = parts stamped x wear cost per part x wear-life consumed% + sharpening charge.
  • Total tooling wear cost works out to 610 $ at these inputs, and this is the headline figure for the scenario.
  • Tooling wear cost per unit works out to 0.01 $ / piece at these inputs.
  • Variable tooling wear cost works out to 390 $ at these inputs.
  • Fixed tooling wear cost adder works out to 220 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where wear-life consumed sits at 90% and the headline result is 760 $, this scenario comes in 19.74% below the baseline at 610 $.
  • Use it when quoting a stamping job, validating a reorder price, or deciding whether the current run should trigger a scheduled die regrind. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total tooling wear cost: 610 $ (headline result)
  • Tooling wear cost per unit: 0.01 $ / piece
  • Variable tooling wear cost: 390 $
  • Fixed tooling wear cost adder: 220 $
