Robotic End-of-Arm Tooling worked example

Vacuum Cup Loss with vacuum cups worn out per hour of 6 units / hr: a worked example

This worked example runs the vacuum cup loss numbers for a tougher week than the baseline: vacuum cups worn out per hour of 6 units / hr instead of the typical 12 units / hr. Estimate vacuum cup loss for robotic end-of-arm tooling using production-ready inputs so teams can budget material or utility usage and compare it with actual consumption.

The inputs for this scenario

  • Vacuum cups worn out per hour: 6 units / hr (the input this scenario stresses; the baseline uses 12)
  • Robot runtime this shift: 8 hr (held at the documented default)
  • Replacement cup cost: 3.5 $ / unit (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Vacuum cup loss consumed = vacuum cup loss use rate × vacuum cup loss runtime.
  • Vacuum cup loss consumed works out to 48 units at these inputs, and this is the headline figure for the scenario.
  • Vacuum cup loss run cost works out to 168 $ at these inputs.
  • Vacuum cup loss runtime works out to 8 hr at these inputs.
  • Vacuum cup loss unit cost works out to 3.5 $ / unit at these inputs.

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 50% below the baseline at 48 units.
  • Use it when budgeting EOAT consumables per shift, comparing cup compounds or suppliers, or building a per-part consumable cost into a quote. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
