Mass Finishing, Deburring & Polishing worked example

Batch Capacity at 65% equipment uptime: a worked example

Suppose equipment uptime falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate batch capacity for mass finishing, deburring & polishing planning, quoting, troubleshooting, capacity review, or process improvement.

The inputs for this scenario

  • Parts processed per finishing cycle: 4 units / cycle (held at the documented default)
  • Available finishing cycles in the period: 480 cycles (held at the documented default)
  • Equipment uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Finishing yield (good parts): 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross batch capacity capacity = units per cycle × available cycles.
  • Good output capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross capacity works out to 1,920 units at these inputs.
  • Uptime loss works out to 672 units at these inputs.
  • Yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where equipment uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • It computes good-part output capacity from gross capacity (parts per cycle times cycles) after applying uptime and yield losses. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Good output capacity: 1,211 units (headline result)
  • Gross capacity: 1,920 units
  • Uptime loss: 672 units
  • Yield loss: 37.44 units
