Composite Tool Life Cost at 110% share of tool cost scope included: a worked example

What does the result look like when share of tool cost scope included reaches 110%? The full calculation is worked below with real intermediate numbers. allocating tool cost across composite production volume

The inputs for this scenario

  • Good tool pulls or parts planned over tool life: 1,200 parts (unchanged)
  • Tool-life cost per pull or part: 18 $ / part (unchanged)
  • Share of tool cost scope included: 110 % (raised for this scenario; the documented default is 100)
  • Fixed tool maintenance and storage cost: 3,200 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable composite tool life cost = good tool pulls or parts planned × tool-life cost per pull or part × tool cost scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 26,960 $ for total composite tool life cost, the number this scenario is built around.
  • At this operating point the engine returns 22.47 $ / piece for composite tool life cost per part or job.
  • At this operating point the engine returns 23,760 $ for variable composite tool life cost.
  • At this operating point the engine returns 3,200 $ for fixed tool maintenance and storage cost.

How this compares with the baseline

  • Against the tool's baseline example, where share of tool cost scope included sits at 100% and the headline result is 24,800 $, this scenario comes in 8.71% above the baseline at 26,960 $.
  • A figure at this level is achievable when share of tool cost scope included is genuinely sustained, not just peaked for a shift. It treats per-pull cost as constant, but real composite tools degrade non-linearly; early pulls are cheap and late pulls near end-of-life may need rework or coating that the flat rate understates.

Results at a glance

  • total composite tool life cost: 26,960 $ (headline result)
  • composite tool life cost per part or job: 22.47 $ / piece
  • variable composite tool life cost: 23,760 $
  • fixed tool maintenance and storage cost: 3,200 $
