Robotic End-of-Arm Tooling worked example

Vacuum Cup Loss with vacuum cups worn out per hour of 30 units / hr: a worked example

This scenario runs the vacuum cup loss calculation on the strong side: vacuum cups worn out per hour of 30 units / hr, with every other input held at its documented default. Use it when vacuum cup loss in robotic end-of-arm tooling is being quoted and consumables are a real chunk of the cost stack.

The inputs for this scenario

  • Vacuum cups worn out per hour: 30 units / hr (raised for this scenario; the documented default is 12)
  • Robot runtime this shift: 8 hr (unchanged)
  • Replacement cup cost: 3.5 $ / unit (unchanged)

Working through the calculation

  • Applying the documented formula (Vacuum cup loss consumed = vacuum cup loss use rate × vacuum cup loss runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 units for vacuum cup loss consumed, the number this scenario is built around.
  • At this operating point the engine returns 840 $ for vacuum cup loss run cost.
  • At this operating point the engine returns 8 hr for vacuum cup loss runtime.
  • At this operating point the engine returns 3.5 $ / unit for vacuum cup loss unit cost.

How this compares with the baseline

  • Against the tool's baseline example, where vacuum cups worn out per hour sits at 12 units / hr and the headline result is 96 units, this scenario comes in 150% above the baseline at 240 units.
  • Use it when budgeting EOAT consumables per shift, comparing cup compounds or suppliers, or building a per-part consumable cost into a quote. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
