Robotic End-of-Arm Tooling worked example

Tool Changeover Time at 12% setup, docking, and delay allowance: a worked example

This scenario runs the tool changeover time calculation on the strong side: 12% setup, docking, and delay allowance, with every other input held at its documented default. Use it when tool changeover time in robotic end-of-arm tooling needs a defensible run time before a quote goes out.

The inputs for this scenario

  • Parts to run before the next tool change: 120 units (unchanged)
  • EOAT throughput rate: 12 units / min (unchanged)
  • Setup, docking, and delay allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where setup, docking, 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.
  • Use it when planning a batch on a robotic cell with an automatic tool changer, or when quoting how long a job with frequent EOAT swaps will actually take. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Required tool changeover time: 11.2 hr (headline result)
  • Base tool changeover time: 10 hr
  • Tool changeover time allowance applied: 12 %
  • Tool changeover time completion rate: 12 pieces / min
