Cut-To-Length Throughput at 65% line efficiency: a worked example

Suppose line 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. Estimate cut-to-length throughput from the sheets cut, the run time, and a realistic line efficiency, so you can compare the line against the required pace.

The inputs for this scenario

  • Sheets cut: 1,200 sheets (held at the documented default)
  • Run time: 8 hr (held at the documented default)
  • Line efficiency: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Cut-to-length rate = sheets cut รท run time.
  • Effective cut-to-length rate works out to 97.5 sheets/hr at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 150 sheets/hr at these inputs.
  • Line efficiency works out to 65 % at these inputs.
  • Run time works out to 8 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where line efficiency sits at 90% and the headline result is 135 sheets/hr, this scenario comes in 27.78% below the baseline at 97.5 sheets/hr.
  • It computes the effective cut-to-length production rate by dividing sheets cut by run time and multiplying by line efficiency. 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 cut-to-length rate: 97.5 sheets/hr (headline result)
  • Raw throughput: 150 sheets/hr
  • Line efficiency: 65 %
  • Run time: 8 hr
