Mass Finishing, Deburring & Polishing worked example

Unload Labor Time at 58% manual handling share of unload: a worked example

Suppose manual handling share of unload falls to 58%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate unload labor time for mass finishing, deburring & polishing planning, quoting, troubleshooting, capacity review, or process improvement.

The inputs for this scenario

  • Parts unloaded in the batch: 100 units (held at the documented default)
  • Unload labor cost per part: 45 $ / unit (held at the documented default)
  • Manual handling share of unload: 58 % (the input this scenario stresses; the baseline uses 80)
  • Fixed setup and cleanup cost: 250 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Unload Labor Time cost = quantity × rate × capture factor + fixed cost.
  • Weighted cost works out to 2,860 hr at these inputs, and this is the headline figure for the scenario.
  • Per piece value works out to 28.6 $ / piece at these inputs.
  • Captured value works out to 2,610 $ at these inputs.
  • Fixed adjustment works out to 250 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where manual handling share of unload sits at 80% and the headline result is 3,850 hr, this scenario comes in 25.71% below the baseline at 2,860 hr.
  • It computes total unload labor cost as parts times per-part cost times the manual-handling share, plus a fixed per-batch cost, and divides back to a per-piece figure. 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

  • Weighted cost: 2,860 hr (headline result)
  • Per piece value: 28.6 $ / piece
  • Captured value: 2,610 $
  • Fixed adjustment: 250 $

Run it with your numbers

  • To rerun this with your own numbers, open the live Unload Labor Time calculator, set manual handling share of unload to your actual value, and adjust the remaining inputs to match your operation.
