Robotic End-of-Arm Tooling worked example

Tooling Amortization at 99% expected utilization: a worked example in robotic end-of-arm tooling

Push expected utilization up to 99% and the picture changes. This example computes every intermediate figure at that operating point. you need a per-part tooling cost to roll EOAT investment into a piece-price or program quote.

The inputs for this scenario

  • Parts handled over tool life: 2,000 parts (000s) (unchanged)
  • Amortized cost per thousand parts: 3.5 $ / 1000 parts (unchanged)
  • Expected utilization: 99 % (raised for this scenario; the documented default is 90)
  • Design, build, and validation cost: 4,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Amortized tooling cost = parts handled x amortized cost per thousand parts x expected utilization + design, build, and validation cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 11,430 $ for total tooling amortization cost, the number this scenario is built around.
  • At this operating point the engine returns 5.72 $ / piece for tooling amortization cost per unit.
  • At this operating point the engine returns 6,930 $ for variable tooling amortization cost.
  • At this operating point the engine returns 4,500 $ for fixed tooling amortization adder.

How this compares with the baseline

  • Against the tool's baseline example, where expected utilization sits at 90% and the headline result is 10,800 $, this scenario comes in 5.83% above the baseline at 11,430 $.
  • It computes the total amortized tooling cost by spreading a per-thousand-parts running rate across expected volume and utilization, then adds the fixed design-build-validation cost, and reports a cost per thousand parts. 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.
