Tooling, Fixtures, Dies & Mold Economics worked example

Tooling Lead Time Buffer at 12% setup, handling, and delay allowance: a worked example

Push setup, handling, and delay allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when tooling lead time buffer in tooling, fixtures, dies and mold economics needs a defensible run time before a quote goes out.

The inputs for this scenario

  • Tooling jobs in queue to process: 120 units (unchanged)
  • Tool room throughput rate: 12 units / min (unchanged)
  • Setup, handling, and delay allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base tooling lead time buffer time = tooling lead time buffer workload รท tooling lead time buffer completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required tooling lead time buffer time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base tooling lead time buffer time.
  • At this operating point the engine returns 12 % for tooling lead time buffer allowance applied.
  • At this operating point the engine returns 12 pieces / min for tooling lead time buffer completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and delay allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • It computes the required tooling lead time in hours by taking base processing time and inflating it by a setup and delay allowance. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required tooling lead time buffer time: 11.2 hr (headline result)
  • Base tooling lead time buffer time: 10 hr
  • Tooling lead time buffer allowance applied: 12 %
  • Tooling lead time buffer completion rate: 12 pieces / min
