Cut-Off Saw Throughput at 65% cutting efficiency: a worked example

Suppose cutting 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. Cut-Off Saw Throughput converts a run's cut count and run time into a raw rate, then discounts for efficiency to give the effective units-per-hour a cold saw, band saw or shear-style cut-off cell truly sustains.

The inputs for this scenario

  • Cut tubes completed in the run: 1,200 units (held at the documented default)
  • Saw run time: 8 hr (held at the documented default)
  • Cutting efficiency (net of stops): 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw cut-off saw throughput = completed output รท runtime.
  • Effective throughput works out to 97.5 units / hr at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 150 units / hr 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 cutting efficiency sits at 90% and the headline result is 135 units / hr, this scenario comes in 27.78% below the baseline at 97.5 units / hr.
  • It computes the raw cut-off saw rate from output and run time, then applies an efficiency factor to give the effective sustainable 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 / hr (headline result)
  • Raw throughput: 150 units / hr
  • Efficiency: 65 %
  • Runtime: 8 hr
