Tube Nesting at 65% nesting cell efficiency: a worked example

Suppose nesting cell efficiency falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Tube nesting throughput measures how many nested tube parts a forming or cutting cell actually completes per hour once real-world efficiency is factored in.

The inputs for this scenario

  • Nested tubes completed per shift: 1,200 units (held at the documented default)
  • Nesting cell runtime: 8 hr (held at the documented default)
  • Nesting cell efficiency: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw tube nesting = completed output รท runtime.
  • Effective throughput works out to 97.5 units at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 150 units at these inputs.
  • Efficiency works out to 65 % at these inputs.
  • Runtime works out to 8 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where nesting cell efficiency sits at 90% and the headline result is 135 units, this scenario comes in 27.78% below the baseline at 97.5 units.
  • It computes raw throughput (completed tubes divided by runtime) and effective throughput (raw rate multiplied by cell efficiency) in units per hour. 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

  • Effective throughput: 97.5 units (headline result)
  • Raw throughput: 150 units
  • Efficiency: 65 %
  • Runtime: 8 hr
